2. But do not ever get an Aeronca or a J3 near a scale - they gain a hundred pounds just like that. They're located in Rochester, Wisconsin (262-534-6315), or on the web at www.amerchampionaircraft.com. Bellanca continued production of the 7GCBC, calling it the Citabria "C" Package (a designation apparently begun by Champion). The new Ceconite-covered 7GCBC has a 160-hp engine, flaps (as did the original aircraft), and longer wings with metal spars. The Citabria was designed and initially produced by Champion Aircraft Corporation, and was a derivative of designs the company had been building since acquiring the 7-series Champ from Aeronca in 1954. The cross-section of the metal fuselage truss is triangular, a design feature which can be traced back to the earliest Aeronca C-2 design of the late 1920s. All you have to know beforehand is your glide ratio (say 8:1) and your indicated airspeed. The electrical system is 12 volts, direct current, using the airframe as a negative ground. ? Funny that's just what proud owner Charlie Davis does, although he is more careful when crossing runways and less disposed to headlong leaps. This means that all else being equal a sailplane can stay in the air for about two to three times as long as a hang glider! Discussion in 'Flight Following' started by Morne, Dec 21, 2011. average spam cans seem to be right around 8 or 9:1. The pilot did an awesome job, cool as a cucumber. Steve Fossett was flying a Bellanca-built Super Decathlon when he went missing on September 3, 2007. Like the Champ, the Citabria features tandem seating. JavaScript is disabled. The 7GCAA . The first quoted paragraph said; . How much does a Citabria cost? Especially when the angle is so slight. A C172 w 9.5/1 glide ratio (L/D) has a 6.01 deg. In addition, metal ribs were nailed to spars, but the nails would pull out. 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. 4. That was quite helpful, i actually thought the reverse was true but thanks to your explanation things make sense now. 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. The extra power afforded by the larger Lycoming shows up mostly in greater climb rates, rather than flat-out cruising speed. It uses the CONDOR Soaring Software Program and is the same simulator used at the USAF Academy. Airplanes fly on excess power, not grace, not engineering. Length: 22 9. #20. The landing gear of the Citabria is in a conventional arrangement. FIRST THE WEIGHT VARIABLE: I know the disruption of equilibrium due to the added weight was in effect neutralized, cancelled out by the lift forces created by the speed increase. What, if any, specialty instruments are used for professional glide ratio testing (such as a manufacturer developing a new model)? American Champion expects to begin building the 7GCAA in a year, but with a 160-hp engine. When the Citabria was introduced, it was the only airplane being commercially produced in the United States which was certified for aerobatics. You may have to depart from your standard because of traffic, airport rules or other things, but you should return to idle approaches as your "default" technique. For a better experience, please enable JavaScript in your browser before proceeding. There were 1,214 Citabria 7GCBC aircraft produced before Bellanca Aircraft Corporation ceased production. The engine is a Lycoming Model O-235-K2C and is rated at 118 horsepower. Bellanca Citabria 7GCBC. Glide ratio usually varies little with vehicle load; a heavier vehicle glides faster, but nearly maintains its glide ratio. Vy in your airplane is 69 mph. Its name spelled backwards is, "airbatic". Also, there is no thrust to move the aircraft. But I think I found your answer from: The Citabria 7ECA can fly up to 11,500 feet and has a top speed of 104 knots, about 120 mph. 1. Vy in your airplane is 69 mph. In this example, the glide ratio provided in the POH comes out . Brian; Not airspeed Joe, Angle of Attack. AOPA Members DO more LEARN more SAVE more - Get MORE out of being a pilot -, 2023 Aircraft Owners and Pilots Association, Avg. That is the lesson we learn about slow flight and stalls. Champion switched to spring steel main gear legs in 1967. ? Ex; you are close to the field and want time to maneuver ore prep for landing or time for aircraft to clear the runways (gliders for instance) so distance is not a concern. Most think this is blasphemy, so take it with a grain of salt: [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. There is a forward component of weight (relative to Drag) that moves the aircraft forward. Mark, not exactly. So tell me (Jim and Paul) what is the AoA for my Citabria or C172 ? Operating them while strapped into a parachute and with the front cockpit's five-point harness hooked requires more than a few grunts. (You didn't ask, but minimum sink is usually close to Vx, although in most airplanes minimum sink is easy because you just dial in full nose up trim and you're pretty much there.). Note as you have increased your IAS (v2) a subsequent decrease in your Angle of attack (cL) is required. Eventually, the Citabria line expanded to four models. fitness for any purpose is made or implied. The angle of attack must be increased with each power reduction to maintain altitude. But the best glide speed for the SR20 is put close to 100 knots, with the DA40 at 70. This is important. Champion 7ECA Citabria - . 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. The 7GCAA and 7GCBC variants, added in 1965, were joined by the 7KCAB in 1968. 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. All of these changes were made in order to allow for extended inverted flight, a mode not possible in the earlier models. The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. View photos, ownership, registration history, and more. How would you go about finding it yourself? With no other changes the plane starts too fall. This airplane is certificated in the normal and acrobatic categories. If the C-172 has an L/D of 9.5. Thanks Jim. Bank Angle The main gear legs of most Citabrias are made of spring steel, though American Champion began to use aluminum gear legs in 2004. Cruise Speed/Endurance with45 MinReserve @ 75% Power: 127mph/ 2.8 hrs, Fuel Consumption(55% to 75% Power, per Lycoming Data): 7.3 to 10gph. 1974 AMERICAN CHAMPION 7-KCAB CITABRIA New Item. when I had my mac attack that is what I did and it seem to work.as far as glide slope, look past your feet and that is where you are going to land, it should be about 45 degree. 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. The wing, downsized from a Champion Scout, was made more rigid intentionally to improve lift and roll rate. We powered pilots often call this Vg or Vbg. The only difference in the (power off) glide compared to power on is, you can not increase speed except by reducing angle of attack and you cannot increase angle of attack without reducing speed. No warranty of At a constant best glide IAS (CAS), the ground speed will be higher at altitude, but the glide ratio will be the same, as it will be offset by a higher descent rate in equal proportion. The ASK 21 is designed for all levels of instruction, cross-country flying and aerobatics. Does the extra weight provide the extra energy to offset the extra drag? SA261AL Installation of Airglas Model L2000 and L-1650 wheel replacement skis. I would like to know the actual glide ratio of my airplane at several combinations of configuration and airspeed. Citabria "A" package The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered The model 7ECA Citabria entered production at Champion in 1964. Daher Kodiak 100 Specifications. Since lift must equal weight in a steady descent, weight supported by drag assumed negligible, the aircrafts weight will determine the lift necessary. On acquiring the design, Bellanca gave this model the name Citabria "Standard" and began using the 115 horsepower (86kW) Lycoming O-235-K2C engine. Minimum sink is always slower than best glide, because it's the point on the power required curve where the least amount of power is required. Higher is better. ItemID: 19782. Aircraft specification no. Yes, L/D is L/D always. It's not a fixed number and the 50:1 ratio will only be achieved at one speed. 10-11:1 otherwise. B) increase You are using an out of date browser. All rights reserved. Due to its light weight, it climbs well, stalls benignly, will land in an incredibly short distance (due to the nose skid), and is an excellent glider for transitioning after solo and first cross country attempts. hotrod180 offline. HERES WHERE MY THINKING MAY GET SCREWED UP. GlobalAir.com is your partner in connecting you with relevant information and resources. Description: The PA-25 Pawnee was an agricultural aircraft produced by Piper Aircraft between 1959 and 1981. The airplane is approved for day and night VFR operations when equipped in accordance with F.A.R. The weight is no longer a factor in this scenario. Agree, especially if you mean the hershey bar variety. Aircraft.com is the leading registry for planes, jets, and helicopters. Our FLSC Pegasus is a B model that has a carbon fiber main spar, The 8KCAB Citabria Pro was first flown by Champion on 2 August 1968, and was a dedicated aerobatic aircraft based on the standard Citabria. Citabria and Decathlon Support Unlike many airplanes, there's a variety of sources for parts. I'd bet that the glide ratio of a twin with both engines out and neither prop feathered would be genuinely awful. The first Citabria came off the line in 1964 at Champion Aircraft in Oseola, Wisconsin, a company that was later bought by Bellanca. Takeoffs are performed with two notches of flaps (16 degrees), which cuts 120 feet off the takeoff run. Do you have the glide ratio in your book? Page 6-Engine Out Glide Distance? This just doesnt seem to jive. I'll bet there are some out there. Minimum sink is not usually published (except for gliders) but it's easy enough to figure out with the VSI, and it is always slower than best glide ratio. The winds would have to be factored in as well. 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. Designed for flight training and personal use, it entered production in the United States in 1945. glide path is not the same as attitude / angle of attack (AoA). History. whether the flaps are deployed, the landing gear is down etc. Both of them start a power off descent at the same time at the same position. To Mark, JAN 10, 2013: American Champion has been using aluminum spars in the aircraft it has produced and has, as well, made the aluminum-spar wings available for retrofit installation on older aircraft. 3. Ever wonder how far you could glide given a certain altitude? It remains a widely used aircraft in agricultural spraying and is also used as a tow plane, or tug, for launching gliders or for towing banners. 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 only effect weight has is to vary the time the aircraft will glide for. IF IM WRONG SOMEBODY OUT THERE PLEASE SET ME STRAIGHT. First and foremost, of course, is American Champion. Champion 7ECA Citabria - 1-2280 - CABLE ASSEMBLY - RUDDER PEDAL. Aircraft weight, air density (e.g. flyingcheesehead, Dec 21, 2011. And, on a side note, do any of you happen to know the glide ratio for a 7GCAA? The heavier the aircraft is, the higher the airspeed must be to obtain the same glide ratio. Not to mention a "what the heck, let's roll it airplane." (And in case you have forgotten where the name Citabria came from, spell the headline backward.). The airspeed and angle of attack are related directly, yes ? Solo Date: November 19, 2022. Most Citabrias were built with wooden spars. Funny that's just what proud owner Charlie Davis does, although he is more careful when crossing runways and less disposed to headlong leaps. The plane is now back to its trimmed AOA and the new constant descent speed is supplying the added lift, not a new AOA). The Glide Ratio calculator computes the glide ratio based on the change in forward distance and the change in altitude. Someone on the internet gave a Vbg of 135MPH for a total glide time of 60 * (6/135) = 2 minutes 40 . You can see the image damage at the end of the video. Horse Power @ RPM: 160 @ 2700 rpm. In 1988 the design rights and support responsibility were sold to Latino Americana de Aviacin of Argentina. Propelle: Sensenich 74DM6S8-1. The POH only gives the best glide distance in the clean condition. In GA aircraft, the speed is given in reference to the max weight. Slow flight was performed at 35 to 40 knots with flaps down. Views: 812 This is before CAM8 increase. Find N57682 1973 BELLANCA CITABRIA 7GCBC on Aircraft.com. Do you disagree? SPECIFICATIONS. Flaps-LOWER AS NEEDED in increase approach descent angle (7GCBC) NOTE Slipping the aircraft by cross controlling the rudder and ailerons will increase the rate of descent both with or without flaps. Glide ratio measures the performance of an aircraft's glide; many modern gliders have a glide ratio better than 60:1. 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. 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. - they gain a hundred pounds just like that apparently begun by Champion ) GA aircraft, the higher airspeed.
