I'll bet there are some out there. The Citabria design based on the Aeronca 7AC Champion. IF IM WRONG SOMEBODY OUT THERE PLEASE SET ME STRAIGHT. 3. 2023 Ask a Flight Instructor All right reserved. Glider: SchleicherASK 21Tail #: ItemID: 19782. The 1979 book I have has performance charts, but my 2001 book doesn't. Go figure. In that period, only one Citabria model was builta 7GCBC marketed as "Citabria 150S." Remember weight does affect stall speed. It is applicable to Serial Numbers 1240-98 and up. The outer shape of the fuselage is created by a combination of wooden formers and longerons, covered with fabric. In other words, the Angle of Attack for best glide will not change. Anyway, best glide is usually very close to Vy, since both speeds are close to the max L/D ratio for that airplane. [2] It was a parasol winged monoplane, with a revised wing section and a longer fuselage. American Champion's 7GCAA, reintroduced in 1997 as the Citabria "Adventure," is similar to earlier versions, with the exception of the metal-spar wings and the use of the Lycoming O-320-B2B engine of 160 horsepower (120kW); the most recent significant design change has been the switch to aluminum main gear legs in 2004. YOU GET THERE QUICKER. 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. How would you go about finding it yourself? Range: 500 miles. Try this Aviation Glide Calculator. The angle of attack must be increased with each power reduction to maintain altitude. Length: 22 9. The extra power afforded by the larger Lycoming shows up mostly in greater climb rates, rather than flat-out cruising speed. The weight is no longer a factor in this scenario. The real-world measurements I've done with our 182 resulted in a 7.04:1 glide ratio. 15:1 from 2000 feet gives a distance of 30000 feet or about 6 miles. The 7GCAA was basically the same as the 7ECA, but with a 150-hp engine. One glide I did from 7500' down to the surface at ~800 MSL resulted in an 11.54 glide ratio. tan(glide angle)=alt/distance. With 5,000 extra lbs in most GA aircraft youd be well above stall speed, which would make you glide at least as well as a rock. When imported it was registered in the USA - as an A model. The landing gear of the Citabria is in a conventional arrangement. Perhaps I am to understand that angle of attack stays the same in best glide, Prop stopped, which helped the glide ratio quite a bit. It yields a glide ratio of a certain number of units forward for a certain amount of altitude lost. the descent speed increases, but the glide ratio . Chris Prev 1 2 3 FirstPrev 3 of 3 Go to page Go The new Cessna 177 Cardinal with its cantilever, laminar-flow wing offering terrific visibility is a doll to fly, a step above its trusty-yet-pedestrian predecessor. Instructor: Scott Williams. The winds would have to be factored in as well. A sport pilot may not act as pilot in command of a light-sport aircraft: That is carrying a passenger or . Notice, there is no weight given here. Isnt this almost exactly the same question answered by figure 3-18 in the airplane flying handbook. 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. The first Citabria came off the line in 1964 at Champion Aircraft in Oseola, Wisconsin, a company that was later bought by Bellanca. 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 . The 7GCAA and 7GCBC variants, added in 1965, were joined by the 7KCAB in 1968. The heavier the aircraft is, the higher the airspeed must be to obtain the same glide ratio. Interested in buying this aircraft click here. Fuel Burn at 75% power in standard conditions per hour. If you have a GPS just hold an airspeed, throttle back, decend a fixed amount and see how far you went. PERFORMANCE Acrobatic Limit Loading: +5, -2g's Takeoff Distance, Ground Roll: 430 ft. Takeoff Distance Over 50-ft Obstacle: 895 ft. Fuel is supplied from two interconnected wing tanks and is gravity fed to the engine carburetor. Pilot's operating manual: Bellanca Citabria, 1975-1977 Series. Does an SR 22 require any additional rating or endorsement? 4. 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. glide path is not the same as attitude / angle of attack (AoA). So if you're looking to cover long distances or stay in the air for a very long time . Fuel quantity is registered by two direct reading float type gauges, one for each tank. - MOUNT ENGINE SET OF 4. Will both airplanes arrive at the same point? The math looks like this: 1.5 nm * 6076.12 ft = 9114.18 ft. Now that both the rise and run are in the same unit value (feet), the ratio can be calculated. WHAT HAPPENS IF WE INCREASE THE WEIGHT THE VERY MOMENT THE GLIDE STARTS? Cleveland - 062-00300 - Piston. American Champion has been using aluminum spars in the aircraft it has produced and has made the aluminum-spar wings available for retrofit installation on older aircraft. Airspeed-65 MPH recommended (60 MPH minimum) 2. I fly over a huge area of good LZ's. Champion introduced the 7KCAB in 1968. D) be indeterminable. This means that if you start at an altitude of 1 mile, you can glide for 60 miles. Information and translations of glide ratio in the most comprehensive dictionary definitions resource on the web. Mark, not exactly. Description: The Schweizer SGS 2-33 is an American two-seat, high-wing, strut-braced, training glider that was built by Schweizer Aircraft of Elmira, New York until the late 1980s, the 2-33 was the main training glider used in North America. The Explorer gave no hint of wanting to swap ends during landings and takeoffs from Warrenton, where there was a slight crosswind. THAT ANGLE OF ATTACK IS THE CORRECT ANGLE FOR THAT PLANES BEST GLIDE SPEED REGARDLESS OF THE PLANES WEIGHT BECAUSE WEIGHT IS NOT A FACTOR IN GLIDING BECAUSE THE AIRPLANE IS PERFECTLY BOUYANT. However if you fly both airplanes, not at their respective L/D, but at the same fixed speed (as it is suggested in most POH, there is a best glide speed) than the maths are different. A high performance glider has a glide ratio of 60:1 (60 miles forward to ever y1 mile of altitude lost). A typical American training glider has a glide ratio of about 24:1. That model was abandoned by aerobatic enthusiasts in favor of the Champion Decathlon 8KCAB because of its better inverted flight performance. Bellanca continued production of the Decathlon throughout the 1970s, moving to the Super Decathlon variant during 1976. In comparison, a Boeing 747 has a 15:1 glide ratio. 45 and 45 is what I was told. The Citabria POH/AFM is a piece of junk, isn't it? As far as flight path is concerned its now like the added weight never existed. ? Federal Aviation Administration. Variations in aircraft weight do not affect the glide angle provided that the correct airspeed is flown. So what does all this gibberish mean, right? All of these changes were made in order to allow for extended inverted flight, a mode not possible in the earlier models. I seem to recall something in the 421 manual saying that the no engine glide speed was well north of 120 mph. On acquiring the design, Bellanca gave this model the name Citabria "Standard" and began using the 115 horsepower (86kW) Lycoming O-235-K2C engine. 2. The aircraft is a 2-place, tandem seating, high wing, single engine airplane and is equipped with conventional landing gear. Just as when you are under power. Login required to see more detailed info on each aircraft. Custom Doggy Mat. If I were to draw the aircraft in gliding flight, we would see that the tan of my glide angle is altitude/distance covered over the ground. The landing gear of the Decathlon is in a conventional arrangement. The first quoted paragraph said; Nationality and Registration MarksZK-CIT. SA261AL Installation of Airglas Model L2000 and L-1650 wheel replacement skis. Fuel Capacity: 36 gal. Cruise Speed/Endurance with45 MinReserve @ 75% Power: 127mph/ 2.8 hrs, Fuel Consumption(55% to 75% Power, per Lycoming Data): 7.3 to 10gph. More Info. You could carry 5000 extra lbs of lead and still glide to the same touchdown point. Now that I think of it, I could carry an extra 5,000 lbs. It's easier from the back seat, but that's not where you solo this aircraft. Left & Right Wing LED Lighting (with Flood & Wig-Wig). Our glider has blocks that can be rotated in front of the rudder pedals to accommodate shorter legged people. Though variants of the design, and other better-suited designs have largely taken over the Citabria's utility roles, Citabrias remain popular as trainers, glider towplanes, and for personal use. Early Citabrias were fitted with a steel tube main gear which uses an oleo strut for shock absorption. You can round 9.11418 down to 9.1. The Decathlon entered production at Champion in 1972, immediately before the company was acquired by Bellanca Aircraft Corporation, so only a handful were produced by Champion. . Take a scenic flight to a favorite restaurant with a "greenhouse" view from the front cockpit (especially if it has the $500 sunroof option), and have an aileron roll along the way as an appetizer. Thus, with changes in weight must come subsequent changes in best glide speed. Bellanca continued production of the 7GCBC, calling it the Citabria "C" Package (a designation apparently begun by Champion). 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. Since lift must equal weight in a steady descent, weight supported by drag assumed negligible, the aircrafts weight will determine the lift necessary. Its name spelled backwards is, "airbatic". Well I stuck my neck out on this one. The 1-26 is the most numerous sailplane found in the US. The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. Compare. Designed for flight training and personal use, it entered production in the United States in 1945. In this example, the glide ratio provided in the POH comes out . The prototype had an open cockpit for a single pilot, but the design allowed for conversion to a two seat layout. 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. The Glide Ratio is the ratio of distance forward to distance downwards when a glider is flown at a constant speed in still air. ** Displayed ranges represent performance at gross weight with standard day conditions in stock configuration. My [flying club's] M20J is about 13:1 a 172 is about 9:1. 2. Recommended Engine TBO: 2000 hours. The angle to the left wing from the pilot eyes is around 5.4 degrees. It may not display this or other websites correctly. Cruise speed: 126 mph. $145.00/hr. 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. 1974 AMERICAN CHAMPION 7-KCAB CITABRIA New Item. 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. Can a student solo cross country have a purpose other than meeting the requirements? 2. Its name spelled backwards, "airbatic", reflects this. Probably displaying my lack of understanding. For example, a 50:1 glider will fly 50m for every 1m it drops. To BART, Jan 10, 2015: The aircraft was powered by a 200hp (150kW) Lycoming IO-360 Special engine driving a two-bladed propeller. This frees you to make the decisions and troubleshoot. They also now manufacture the Citabria Adventure and the Citabria Explorer. Engine off landings, and best glide speed to achieve the "longest distance" are not the same technique for all gyros. Keep in mind, though, you're going quite a bit slower than your best glide speed, and that can significantly impact your glide range. The Explorer proved to be equally docile during stalls, proving its value as a trainer. I can fly 40% over gross weight and go just as far as the lightest of the same design! 8-10:1. best glide speed is really high though thanks to much higher wing loading. Operating them while strapped into a parachute and with the front cockpit's five-point harness hooked requires more than a few grunts. A modern German counterpart about 33:1. By continuing to use this website, you are agreeing to our Cookie Policy. 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. Production was completed in 1981. tan -1 (1/14) or tan -1 (0.714) or 4.086 degrees. Department of Transportation. STICK AND RUDDER says the terms airspeed and AOA are just two ways of saying the same thing. 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 ? Champion 7ECA Citabria - BUSHING. Data from Jane's All the World's Aircraft 196970[2], Aircraft of comparable role, configuration, and era. ? Using the Explorer to give tailwheel transition training to a nosewheel pilot is almost cheating, given the aircraft's well-mannered behavior. ). SECOND THE SPEED VARIABLE: I know the AOA did not change. Lighter Total system is now 3 lbs. 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. There is this sweet spot where both are minimized and that is where you will find your best aircraft glide performance. Perversely, adding weight means that the best glide angle occurs at a faster speed. They were also found in utility roles as bush planesthanks to their short take off and landing (STOL) ability, agriculture, pipeline patrol, and as glider towplanes. The math looks like this: 9114.18 ft /1000 ft = 9.11418. This should be a indicated airspeed you should try and maintain the second your engine quits or starts sputtering. Additionally, the positioning of the flap handle offers little leverage advantage. (And in case you have forgotten where the name Citabria came from, spell the headline backward.). With only half tanks, we were still right at the new, higher gross weight of 1,800 pounds. Available in several versions, with varying powerplants and equipment, the Citabria and its stablemate, the Decathlon, have a great deal to recommend them to the recreational flyer. 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. 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.
