Champion's first Citabria flew as a prototype in May 1964. Boldmethod. The fuel tanks are vented together with the vent located on the left wing. I also know there is a direct relationship between AOA and airspeed. On acquiring the design, Bellanca gave this model the name Citabria "Standard" and began using the 115 horsepower (86kW) Lycoming O-235-K2C engine. In this example, the glide ratio provided in the POH comes out . Our FLSC Pegasus is a B model that has a carbon fiber main spar, In the King Air sim I developed a fuel-contamination scenario at 5,000' in a terminal area in which both fuel pressure lights illuminated with autofeather MEL'd out of service (it's an option). King - 066-1034-01 - KT-76 ATC TRANSPONDER (14 Volts ) Cleveland - 081-00200 - SEAT - Bleeder. Description: The G102 Astir is a single seat fibreglas 15m Standard Class sailplane with a retractable wheel, designed by and built by Grob Aircraft, with the first flight in December 1974. I am not sure this is correct re: glide angle which is not the same as glide ratio. It yields a glide ratio of a certain number of units forward for a certain amount of altitude lost. Glider: SchleicherASK 21Tail #: Rolls are okay, though and loops. The extra energy from the weight does nothing to the drag. The pilot suffered a catastrophic engine failure (cylinder separation) in a Cessna 205. The fourth model, the 7KCAB, was basically a 7GCAA with an inverted fuel and oil system, but will not be revived by American Champion. TO OUR GLIDE RATIO (AND ITS RESULTANT GLIDE SLOPE)? That model was abandoned by aerobatic enthusiasts in favor of the Champion Decathlon 8KCAB because of its better inverted flight performance. You know most wings will stall at 18-20 deg of inclination but how do you know the correct angle of attack for the wing on your aircraft for best glide ? twins are probably in the same range for engine out L/D i.e. Pretty impressive. Length: 22 9. The airplane is approved for day and night VFR operations when equipped in accordance with F.A.R. But a lovely bird. The outer shape of the fuselage is created by a combination of wooden formers and longerons, covered with fabric. 1974 AMERICAN CHAMPION 7-KCAB CITABRIA New Item. Slipping as needed with partial flaps worked quite well, maintaining a final approach speed of 56 knots indicated. Description: Our Club purchased this glider simulator in 2019 for our students from Russell Holtz. Assume: XXXX lbs, alt.= 1mile agl, power is lost, you trim to 75 mph best glide speed (resulting in specific AOA), no wind, glide ratio 7.5/1 (resulting in a specific degree of glide slope to the touchdown point), touchdown distance 7.5 miles, glide time 6 minutes. by the manufacturer or FAA. If you wish to make some sort of pursuasive argument then post up some horrid examples of glide ratios for twins. The large wing area gives good low-speed handling characteristics, docile stalling characteristics, a excellent climb. Overall, the aircraft delivers what it promises: fun. Bellanca Citabria 7GCBC. There is a forward component of weight (relative to Drag) that moves the aircraft forward. Instead of best glide SPEED, memorize best glide ATTITUDE. . Table of Contents. Yippee! Birdyspot on. A glider improves its glide ratio relative to the earth by speeding up if there is a headwind, or a downdraft. Perhaps I am to understand that angle of attack stays the same in best glide, tan(glide angle)=alt/distance. This is a question I was asked a few days ago, and I cant find the correct answer. 2. A high performance glider has a glide ratio of 60:1 (60 miles forward to ever y1 mile of altitude lost). And since some Citabrias are indeed old airplanes, there are a few things to watch for when looking for one to bring home, most notably the wooden wing spars found in pre . One of my favorite civilian birds of all time.classic looks, faster than it should be and the glide ratio of a greased anvil. Every once in a while I get a question on askacfi.com that Im pretty sure is a homework question but I still dont mind answering it. We powered pilots often call this Vg or Vbg. L=cL(1/2 x Rho x v2) S. Higher weight requires higher lift. Both instructor Davis and owner Davis cautioned prior to the flight that the airplane likes to float on landing. Dec 19 2022. Chris Prev 1 2 3 FirstPrev 3 of 3 Go to page Go Page 6-Engine Out Glide Distance? Aircraft.com is the leading registry for planes, jets, and helicopters. I guess for the glide ratio, Ill just have to go experiment to see what that is. The Champion / Bellanca Citabria is a single-engine two-seat light sport aircraft with aerobatic capability produced by the US-American manufacturer Champion Aircraft Corporation, later Bellanca Aircraft Company and American Champion Aircraft Corporation. THE TOUCHDOWN POINT IS UNCHANGED More Info. $10.00. The 7GCBA (ag spray plane) is certified to 2400lbs (I admit I know nothing about it's structure). Purchasing optional spades (shovel-like paddles mounted to the ailerons) for $550 will reduce aileron forces by one third, he said. Maximum speed: 162 mph. One of the major developments of the 8KCAB Decathlon over the 7KCAB Citabria is the Decathlon's wing, which employs a semi-symmetrical airfoil, as opposed to the Citabria's flat-bottomed airfoil. (You must log in or sign up to reply here. A sport pilot may: Share the operating expenses of a flight with a passenger, provided the expenses involve only fuel, oil, airport expenses, or aircraft rental fees. Higher is better. Federal Aviation Administration. Glide ratio is defined as the ratio between altitude when it start gliding (Y-axis) to the distance it can reach until the altitude reach zero (X-axis), as shown in the picture 2. Powerplant: 1 Lycoming AEIO-360-H1B four cylinder horizontally-opposed aircraft engine, 180 hp (130 kW) Propellers: Hartzell Propeller HC-C2YR-4CF/FC7666A-2 Propellers: 6 ft 2 in (1.88 m) diameter Performance Maximum speed: 155 mph (249 km/h, 135 kn) at sea level Cruise speed: 141 mph (227 km/h, 123 kn) So if he creates a few wings sets (6 or 7) with the same surface and varying only the cord and span starting with low aspect moving onto high aspect and seeing which ones glide furthersomewhere in there he would find the "right" AR. The trim control, same as that used on earlier Citabrias and Decathlons, is a sliding knob, much like the throttle, that is fast and simple to operate. The lighter? My [flying club's] M20J is about 13:1 a 172 is about 9:1. Using trigonometry we get an angle of about 4 degrees below the horizon. ** Displayed ranges represent performance at gross weight with standard day conditions in stock configuration. The most noticeable external changes to the design are the Citabria's squared-off rudder surface, wingtips, and rear windows. (The Citabria was certified under older CAR 4a regulations, when a more extensive flight manual was not required.) Mark, not exactly. Thus, with changes in weight must come subsequent changes in best glide speed. To take advantage of the new light-sport aircraft category, the Champion was returned to production in 2007. With no other changes the plane starts too fall. ? The main gear legs of most Citabrias are made of spring steel, though American Champion began to use aluminum gear legs in 2004. Your glide ratio needs to be determined empirically. SPECIFICATIONS. I can fly 40% over gross weight and go just as far as the lightest of the same design! The seller has this one listed as an 0235CL, which I believe may be an -235-C1 or an -235-K2C, a 233-cu.in. In addition, metal ribs were nailed to spars, but the nails would pull out. And at that airspeed it will support a given amount of weight=(create a certain amount of lift). Airplanes fly on excess power, not grace, not engineering. Wikipedia (https://en.wikipedia.org/wiki/Gliding_flight#Glide_ratio). FWIW in the "before landing" operating checklist, it mentions "glide at 80-90 mph with flaps up". The real-world measurements I've done with our 182 resulted in a 7.04:1 glide ratio. Posts: 9992. In GA aircraft, the speed is given in reference to the max weight. 7ECA, Citabria Standard, Citabria Aurora. I asked Charlie if I could come back just to play. a pretty decent policy in airplanes is that if you can see it over the nose there is good odds you can't make it there. They also are are not equal if there is horizontal or vertical wind. The engine was replaced with a Lycoming IO-320-E2A of 150 horsepower (110kW), while a header tank of 1.5 gallonslocated beneath the instrument panelwas added to the fuel system. 4. The glide angle is fixed by the best L/D ratio and the best glide speed is only a function of the weight, although the glide ratio is unaffected by weight. [2] It was a parasol winged monoplane, with a revised wing section and a longer fuselage. Introduced in 1965, the Champion 7GCAA, like the 7ECA, featured wood-spar wings and oleo-shock main gear. Designed for flight training and personal use, it entered production in the United States in 1945. The cross-section of the metal fuselage truss is triangular, a design feature which can be traced all the way back to the earliest Aeronca C-2 design of the late 1920s. (if I could put a figure in here I would draw out the vector relationship). Its name spelled backwards, "airbatic", reflects this. The Citabria traces its lineage back to the Champ. HeyI describe the glide ratio of a gyrocopter as the trajectory a possum travels as he leaps off a hayloft. I fly over a huge area of good LZ's. Does an SR 22 require any additional rating or endorsement? Instructor Davis said the aircraft requires a long, flat approach, but that was inhibited somewhat at Warrenton by trees off the approach end. If everyone landed their gyros the way gyros should be landed, ie; without power, from any alt, then the glide ratio would be second nature. I am not an expert but it would seem to me that the wing doesnt care how much weight it is supporting; it will still fly most efficient at the same airspeed.. The fuselage and tail surfaces are constructed of welded metal tubing. So.., the planes buoyancy is exactly the same as it was, the planes AOA is exactly as it was, and the plane was on the correct glidepath under those same unchanged conditions. The Kodiak is a true STOL (Short Take Off and Landing) aircraft powered up front by a PT6A-34 producing 750 shp allowing the Kodiak to get off the ground in just under 1,000 feet . If you have a GPS just hold an airspeed, throttle back, decend a fixed amount and see how far you went. . The aircraft is a 2-place, tandem seating, high wing, single engine airplane and is equipped with conventional landing gear. A "High Country Explorer" version, with a Superior Vantage O-360-A3A2 engine of 180 horsepower (130kW) and larger wheels, is also produced by American Champion. Like the Citabria, the Decathlon features tandem seating and center-stick controls. So tell me (Jim and Paul) what is the AoA for my Citabria or C172 ? glide path is not the same as attitude / angle of attack (AoA). Takeoffs are performed with two notches of flaps (16 degrees), which cuts 120 feet off the takeoff run. The glide ratio is based only on the relationship of the aerodynamic forces acting on the aircraft. The model 7ECA Citabria entered production at Champion in 1964. . Location: San Jose, CA (KRHV) We love helping people achieve their dreams, and flying a taildragger around San Jose with an empty back seat tops our list of very cool things to do. How would you go about finding it yourself? I don't know of a list. The winds would have to be factored in as well. You have to explain that a little better than that. Login required to see more detailed info on each aircraft. Aircraft The Explorer proved to be equally docile during stalls, proving its value as a trainer. The landing gear of the Citabria is in a conventional arrangement. Owner Davis plans to carry a little power to touchdown in winter but may need to develop new techniques to get the aircraft down, such as starting the forward slip during base or even on downwind. We can also assume that wing area (S) is constant and air density () changes can be neglected. When imported it was registered in the USA - as an A model. Probably displaying my lack of understanding. SAVE Last Update: 02/24/2023. Champion 7ECA Citabria - BUSHING. On this Wikipedia the language links are at the top of the page across from the article title. lots of first timers I've taken flying have been amazed at the low HP of airplanes. And it means you have more vertical speed to arrest in that latter phase. A 5 deg angle (glide path) gets you 1909 feet farther while Citabrias were also popular as trainersbecause of their conventional gear and their aerobatic capabilitiesand as personal aircraft. The Champion two seat aircraft was powered by a 108hp Continental fourcylinder engine. The heavier the aircraft is, the higher the airspeed must be to obtain the same glide ratio. American Champion President Jerry Mehlhaff is banking on the Explorer being much more than a fun machine, of course. The American Champion Super Decathlon uses the AEIO-360-H1B, along with a constant speed propeller. B) increase Will both airplanes arrive at the same point? tan -1 (1/14) or tan -1 (0.714) or 4.086 degrees. BUT ONLY IF THE PLANE WAS DESIGNED WITH WINGS TO SUPPORT SUCH A LOAD. A sport pilot must pay at least half the operating expenses of the flight. Introduced in 1964, the 7ECA was the first version of the design and utilized the Continental O-200-A engine of 100 horsepower (75 kW). It is our mission to be the go to leaders in the aviation industry. Agree, especially if you mean the hershey bar variety. Further practice would reduce the landing distance still further. No Oil Required Fuel Capacity: 36 gal. More speed equals more drag which translate into a higher sink ratewhich translate in loosing more altitude for the same amount of time unit The flight path and the AoA are 2 different things not to be confused. hotrod180 offline. But the best glide speed for the SR20 is put close to 100 knots, with the DA40 at 70. Try to run your car at 75% power and see how long it lasts. Brian; Not airspeed Joe, Angle of Attack. Especially when the angle is so slight. It is found by multiplying the weight by the sine of the glide angle. Glide ratio usually varies little with vehicle load; a heavier vehicle glides faster, but nearly maintains its glide ratio. GlobalAir.com is your partner in connecting you with relevant information and resources. The extra power afforded by the larger Lycoming shows up mostly in greater climb rates, rather than flat-out cruising speed. (just kidding). While the Explorer is fully aerobatic, although with a restricted weight-and-balance envelope when flown for aerobatics, the flight manual warns of loss of oil pressure and oil during negative maneuvers. [2] It was never put into production at Champion nor by Bellanca which acquired the company and designs only a short time later. Aircraft Owners & Pilots Association Find it free on the store. In fact, the Citabria is approved for 10 aerobatic maneuvers. RV General Discussion/News The electrical system is 12 volts, direct current, using the airframe as a negative ground. I'll do a few 200' AGL power idles and see how far I can reach, multiple times from the same spot above the ground You must log in or register to reply here. 2023 Ask a Flight Instructor All right reserved. ). Remains of the plane were found 13 months later near the town of Mammoth Lakes, California, just south of the original search area. Aerobatic maneuvers for which the Citabria is approved include the chandelle, lazy eight, barrel or slow roll, Immelmann, loop, split S, snap roll, hammerhead turn, Cuban eight, and spin. American Champion's 7GCBC, reintroduced in 1994 as the Citabria "Explorer," is similar to earlier versions, with the exception of the metal-spar wings and the use of the Lycoming O-320-B2B of 160 horsepower (120kW); the most recent significant design change has been the switch to aluminum main gear legs in 2004. The 2-33 first flew in 1965 and production was started in 1967. Congrats to Ian and CFI Scott for checking this box off his list. (35 gal. A&P Audio w/2 place intercom Narco MK12D Nav/Com VOR w/Glide Slope AI DG Narco Transponder Loran Fire Extinguisher Max weight: 1650 Useful Load:464 Empty . To aid in getting down, it is recommended that power be reduced to idle opposite the point of intended touchdown. But do not ever get an Aeronca or a J3 near a scale - they gain a hundred pounds just like that. Disclaimer: Information on this site may not be accurate or current and is not valid for flight planning or any other aircraft operations. But I think I found your answer from: The aircraft was powered by a 200hp (150kW) Lycoming IO-360 Special engine driving a two-bladed propeller. Demonstrated Crosswind Component: 17kts. Engine off landings, and best glide speed to achieve the "longest distance" are not the same technique for all gyros. And, on a side note, do any of you happen to know the glide ratio for a 7GCAA? Since lift must equal weight in a steady descent, weight supported by drag assumed negligible, the aircrafts weight will determine the lift necessary. the glide ratio is independent of the weight or mass of the aircraft. Vy in your airplane is 69 mph. . Sorry, JavaScript must be enabled.Change your browser options, then try again. Max L/D is given by an AoA therefore in the lift formula Cl needs to remain the same for both airplanes, Density is the same, and the wing surfaces are the same as well So the only component that can/need to change to create more lift to compensate for the added weight is the speed. The major improvement in Bellanca's introduction of the Super Decathlon was the change of engine to the Lycoming AEIO-360-H1A or H1B, both of 180 horsepower (130kW), which was accompanied by a selection of constant speed propellers. Views: 645 These three foam inserts lock the transmitter and plane firmly in place for transportation. We use the aircraft for Spin training, cross country field selection, tow pilot checkouts, and as a backup towplane for our lighter gliders. Thus, the only remaining variable left to change our lift is velocity (V), or airspeed. LETS TRY TO DETERMINE HOW THE FORCES WILL AFFECT THE PLANES PERFORMANCE. hope this might help. This frees you to make the decisions and troubleshoot. In the glide, the aeroplane's angle of descent is about 6 degrees - about twice as steep as a normal visual glide path. American Champion Aircraft Corporation acquired the Citabria, Decathlon, and Scout designs in 1989 and returned the 7ECA, 7GCAA, and 7GCBC models to production over a period of years. Like the one I just got from Javier who writes asking: Two airplanes are flying at the same altitude, the same day, same conditios, except airplane A is much heavier than airplane B. Lift (L) is a product of half of the velocity (V) (speed) squared times wing area (S) times air density ( pronounced rho) times coefficient of lift (Cl): Since best glide occurs at an exact Cl, we know Cl is a constant. For a better experience, please enable JavaScript in your browser before proceeding. Bellanca continued production of the Decathlon throughout the 1970s, moving to the Super Decathlon variant during 1976. This Bellanca Citabria is ready for an afternoon of fun! IF IM WRONG SOMEBODY OUT THERE PLEASE SET ME STRAIGHT. Bellanca continued production of the 7KCAB as the Citabria "B" Package (a designation apparently begun by Champion). Since it is the lift over drag (L/D) ratio that determines the gliding range, weight will not affect it. Lighter Total system is now 3 lbs. Login . Like the Champ, the Citabria features tandem seating. Find N57682 1973 BELLANCA CITABRIA 7GCBC on Aircraft.com. Aircraft specification no. American Champion Citabria 7ECA Technical Specifications Exterior Exterior Height: 7 ft 7 in Wing Span: 33 ft 6 in Length: 22 ft 1 in Interior Cabin Height: 3 ft 11 In Cabin Width: 2 ft 6 In Cabin Length: 8 ft 10 In Occupancy Crew: 1 Passengers: 2 Operating Weights Max T/O Weight: 1750 Lb Empty Weight: 1120 Lb Fuel Capacity: 35 Lb The 180-hp Decathlon, already in production at American Champion, is the company's biggest seller accounting for 16 of the 18 sales made so far this year (see " The New Champion," October 1991 Pilot). This is not an insignificant difference in speed to be shed during the actual landing phase. The 1979 book I have has performance charts, but my 2001 book doesn't. Go figure. The L/D ratio and the glide ratio are always equal in steady-state linear unpowered flight in still air, but they are not equal if there is some thrust from a motor. The Decathlon entered production in the United States in 1970 as a more powerful and stronger complement to the American Champion Citabria line of aircraft. that specific attitude. Just as when you are under power. Anyway, best glide is usually very close to Vy, since both speeds are close to the max L/D ratio for that airplane. The weight is no longer a factor in this scenario. Heres one from aerodynamics test: So if I were at 10000 feet and lost all my engines, I could expect to glide about 30 miles. Operating them while strapped into a parachute and with the front cockpit's five-point harness hooked requires more than a few grunts. Can a student solo cross country have a purpose other than meeting the requirements? [2] He took off from an airstrip at William Barron Hilton's Flying-M Ranch, about 70 miles (110km) southeast of Reno, Nevada. Merry Christmas everyone! Probably closer than you think. Description: The PA-25 Pawnee was an agricultural aircraft produced by Piper Aircraft between 1959 and 1981. The wood winged 7GCBC weight go up to 1800lbs on edo 2000 floats. The plane is now EXACTLY as buoyant as it was before. Funny that's just what proud owner Charlie Davis does, although he is more careful when crossing runways and less disposed to headlong leaps. Can you or anyone judge 6.01 deg glide path (not angle of attack) This can be the difference between going home ! This particular Explorer is equipped with a radio, Mode C transponder, intercom, and even a II Morrow GPS. The airplane is powered by a horizontally opposed, four cylinder, direct drive, normally aspirated, air cooled, carburetor equipped engine. It uses the CONDOR Soaring Software Program and is the same simulator used at the USAF Academy. BUT The plane resists the new AOA because its trimmed for a specific AOA, which it is engineered to want to re-establish, maintain. The 8KCAB Citabria Pro was first flown by Champion on 2 August 1968, and was a dedicated aerobatic aircraft based on the standard Citabria. N70FP SN#101A202, Glider: SchweizerSGS 1-26ATail #: For airplanes with the same aerodynamic characteristics, no wind, starting at the same altitude, and both of them flying at their corresponding speed to achieve max L/D. Both at the same time? (Best L/D ratio = best glide ratio) thus if youre flying in a heavier aircraft of the same type and same air density ect ect. All bets are off when the wing stalls. When introduced, it featured wood-spar wings and oleo-shock main gear. N7519F, Tow: PiperPA-25-235 PawneeTail #: Recommended Engine TBO: 2000 hours. How do you determine the best engine off glide ratio in a gyro? Use tab to navigate through the menu items. Wing aspect ratio: 6.72; Length overall: 22 ft 8 in (6.91 m) Height overall: 7 ft 0 in (2.13 . In 1970, Champion was acquired by Bellanca Aircraft Corporation, which continued production of all of the Champion-designed variants. $85,500 Reg# N8552V TT: 2408; Performance Specs. The airspeed and angle of attack are related directly, yes ? Do you disagree? Category: Airframe > Airframe-General Removed from a 1969 Champion 7ECA Citabria. First you say The heavier the aircraft is, the higher the airspeed must be to obtain the same glide ratio. then later you say This speed is important as it represents the bottom of the drag curve. Perversely, adding weight means that the best glide angle occurs at a faster speed. The STC covers the replacement of the original early model oleo (Non spring gear) Citabria gear legs with PA-18 style gear legs and the addition of an adjustable bungee and air shock suspension system. The literature refers to a specific angle of attack, for best glide but how does one know the exact angle of attack, really ? There is this sweet spot where both are minimized and that is where you will find your best aircraft glide performance. Welcome Guest. A C172 w 9.5/1 glide ratio (L/D) has a 6.01 deg. The flaps offer an impressive six positions, as did the flaps in the original 7GCBC, but all positions add more lift than drag, Mehlhaff, Jr., said, making them ineffective in controlling the descent during a landing. The heavier? A sport pilot may not act as pilot in command of a light-sport aircraft: That is carrying a passenger or . An aircraft has a single best glide speed for a given configuration. Airspeed-65 MPH recommended (60 MPH minimum) 2. How to stop ignition interference on radio. [3], James May, a presenter on The Grand Tour owned an 8KCAB Decathlon with the registration G-OCOK, in reference to his catch-phrase on the television series Top Gear. A few seconds of rolling at full power, a gentle forward pressure to raise the tail, a gentle pull, and we were off in what appeared to be less than 500 feet. the heavier plane will reach the ground faster. It was substantially similar to the 7GCAA of the same year, with wood-spar wings and spring steel main gear legs. If the weight is reduced and the IAS held constant, the glide angle will: I just read elsewhere that altitude / air density does not effect glide ratio but it seems your explanation says it does effect glide ratio. This airplane is certificated in the normal and acrobatic categories. It is applicable to Serial Numbers 1240-98 and up. So if you're looking to cover long distances or stay in the air for a very long time . The POH only gives the best glide distance in the clean condition. Let me know what you think. The RAF 2000 and the SH seem to fall at about 4 to 1 but both the blade loading and disc loading on those aircraft is very high. Intended as a lower-priced competitor to the Piper Super Cub, Mehlhaff sees it as a utility aircraft, whether it be on floats or skis, and as a glider tug aircraft. Horse Power @ RPM: 160 @ 2700 rpm. A) decrease Pilot's operating manual: Bellanca Citabria, 1975-1977 Series. The major difference was in the engine, which in the 7GCAA was a Lycoming O-320-A2B of 150 horsepower (110kW). The outer shape of the fuselage is created by a combination of wooden formers and longerons, covered with fabric. Notice, there is no weight given here. It was substantially similar to the 7GCAA of the same year, with a Lycoming O-320-A2B engine of 150 horsepower (110kW), wood-spar wings, and spring steel main gear legs. Is posible descent the same distance from the same altitude and land at the same point with diferent angles? i dont see it. Both aircraft will cover the same distance but the lighter one will take a longer time to do so. 13:1 with the prop stalled, MAYBE. The Citabria POH/AFM is a piece of junk, isn't it? JavaScript is disabled. Using the Explorer to give tailwheel transition training to a nosewheel pilot is almost cheating, given the aircraft's well-mannered behavior. NO OTHER CHANGES. Citabria 7ECA. SECOND THE SPEED VARIABLE: I know the AOA did not change. Variations in aircraft weight do not affect the glide angle . A Cessna 172 might glide at 8:1, so it could go 8000 feet forward for each 1000 feet it lost at a Vg of 65 knots indicated (KIAS). Demonstrated Crosswind Component: 17 kts. Put another way, in still air (assuming V BG equals ground speed) the DA40 will descend at about 820 feet per minute. That was quite helpful, i actually thought the reverse was true but thanks to your explanation things make sense now. Top of wing tip to top of cabin 2 feet. Stepping into the Cardinal is more like sliding into a sedan than climbing into a pickup. It can be used for spin training with tailweights added. Interested in buying this aircraft click here. It's fair to say the Citabria goes back a waysall the way to the beginning, in fact. Someone on the internet gave a Vbg of 135MPH for a total glide time of 60 * (6/135) = 2 minutes 40 . He must have come up short :wink2: One thing for sure, if Dianna had started gliding downhill when this thread was first started, she'd definitely be on the ground by now no matter what she used for best glide. N20737, Glider: HoltzMach 0.1 SimulatorTail #: The lift produced during the glide is not equal to weight, it is equal to weight times the cosine of the glide angle! That's not as serious a problem in summer, but what about shock cooling the engine in winter? flyingcheesehead, Dec 21, 2011. Champion switched to spring steel main gear legs in 1967. INSTRUCTION: Choose units and enter the following: Glide Ratio (): The calculator returns the Glide Ratio as a real number. In that period, only one Citabria model was builta 7GCBC marketed as "Citabria 150S." Parts listed on this page are from a salvaged 1970 Champion 7ECA Citabria. Or is the extra drag just neglected in the calculation? ). Most think this is blasphemy, so take it with a grain of salt: Weight opposes lift, it does not oppose drag. At a critical point angle of attack, the aircraft can maintain altitude only by increasing power and is said to be behind the power curve. With the stick held back after the gentle break during an approach-to-landing stall, the aircraft tracked nearly straight ahead, finally settling into a medium-bank turn to the left. Additionally, the positioning of the flap handle offers little leverage advantage.
