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. (You must log in or sign up to reply here. 3, 2005.) ? Table of Contents. A glider improves its glide ratio relative to the earth by speeding up if there is a headwind, or a downdraft. Solo Date: November 19, 2022. If the weight is reduced and the IAS held constant, the glide angle will: Cleveland - 062-00300 - Piston. N3822A, Glider: SchweizerSGS 2-33ATail #: whether the flaps are deployed, the landing gear is down etc. 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. 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. I don't know of a list. The extra weight is balanced by the extra lift The American Champion Super Decathlon uses the AEIO-360-H1B, along with a constant speed propeller. So Joe, Jim and Paul are correct but they have not told us how they determine I seem to recall something in the 421 manual saying that the no engine glide speed was well north of 120 mph. It offers the added advantage of increasing wing strength. 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 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. The Citabria designs passed through the hands of a number of companies through the 1980s, including a Champion Aircraft Company which was no relation to the Champion Aircraft of the 1960s. 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.. Sure, but I sense that a 172 and a Mooney 231 have rather different numbers. glide path. We use cookies to help you get the best experience when using our website. This Bellanca Citabria is ready for an afternoon of fun! It can be used for spin training with tailweights added. Wing aspect ratio: 6.72; Length overall: 22 ft 8 in (6.91 m) Height overall: 7 ft 0 in (2.13 . Because the AOA remained unchanged, this once again perfectly balanced plane will remain on its same glidepath and arrive at the same touchdown point. Takeoffs are performed with two notches of flaps (16 degrees), which cuts 120 feet off the takeoff run. The Champion two seat aircraft was powered by a 108hp Continental fourcylinder engine. [2] It was a parasol winged monoplane, with a revised wing section and a longer fuselage. 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. Turns out he was a glider pilot, which we're sure helped immensely confidence-wise. N20737, Glider: HoltzMach 0.1 SimulatorTail #: There were 1,214 Citabria 7GCBC aircraft produced before Bellanca Aircraft Corporation ceased production. For example, a 50:1 glider will fly 50m for every 1m it drops. Best glide ratio is the most optimal - the highest - one. Champion switched to spring steel main gear legs in 1967. 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. Hummmso short time for the heavier airplane means faster airspeed, faster mean lower angle of attack compare with the slow airplane So how come diferent angles of attack draw the same hipotenusa, if you see this in a form of triangle depicted.? Or is the extra drag just neglected in the calculation? the descent speed increases, but the glide ratio . 3. The glide ratio varies with air speed, but there is a maximum value which is frequently quoted. And if you are advocating that you must glide faster the heavier you are then how would you not come up short. Maximum speed: 162 mph. THE ONLY THING WEIGHT DOES IS BRING THE PLANE DOWN THE GLIDE PATH AT A FASTER RATE. altitude) have no effect on the glide ratio. Arrow is famous for a safe glide ratio - glides like a safe. The pilot suffered a catastrophic engine failure (cylinder separation) in a Cessna 205. If two aircraft have the same L/D ratio but different weights and start a glide from the same altitude, the heavier aircraft gliding at a higher airspeed will arrive at the same touchdown point in a shorter time. American Champion Citabria 7ECA Pre-Cut Carpet Kit. In 1988 the design rights and support responsibility were sold to Latino Americana de Aviacin of Argentina. 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. Bellanca continued production of the 7KCAB as the Citabria "B" Package (a designation apparently begun by Champion). The similar, although more rugged, 8 series is used for the Scout bushplane and the more fully aerobatic Decathlon. ItemID: 19782. 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 It is good to know what your "best" glide ratio is, such as most single engine training airplanes are in the 9:1 glide ratio. Interested in buying this aircraft click here. 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. Older Citabria 7GCBC aircraft produced in the 1960s and 1970s had wood spars that are prone to cracking. On this Wikipedia the language links are at the top of the page across from the article title. 91 or F.A.R 135. By continuing to use this website, you are agreeing to our Cookie Policy. Compared to the Citabria's wingspan of 33.5 feet (10.2m), the Decathlon's wingspan is shorter, at 32 feet (9.8m). 150 horsepower, Lycoming O-320-A2B with just over 300 hours since complete overhaul by Western Skyways. Recommended Engine TBO: 2000 hours. Compare. 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 the two aircraft were to start gliding from a mile high altitude, the 172 would glide about .8 miles further than the phantom. The Citabria is based on the Champion 7-series airframe. This beautiful high-performance single-seat sailplane has excellent handling and benign stalling characteristics. Champion 7ECA Citabria - 1 . Views: 614 The Micro Citabria charger stand is identical to the Cessna. Champion 7ECA Citabria - 1-2280 - CABLE ASSEMBLY - RUDDER PEDAL. Like the Citabria, the Decathlon features tandem seating and center-stick controls. glide path is not the same as attitude / angle of attack (AoA). So, there isn't better glide performance at altitude. Prop stopped, which helped the glide ratio quite a bit. The outer shape of the fuselage is created by a combination of wooden formers and longerons, covered with fabric. Heres one from aerodynamics test: IF IM WRONG SOMEBODY OUT THERE PLEASE SET ME STRAIGHT. So I'd guess best glide speed is 80-ish. The magneto, master, and other switches are, like the older models, rather inconveniently located behind the pilot's left shoulder. 2. Landing Distance over 50-ft. tan -1 (1/14) or tan -1 (0.714) or 4.086 degrees. Range: 500 miles. The airspeed and angle of attack are related directly, yes ? The outer shape of the fuselage is created by a combination of wooden formers and longerons, covered with fabric. Engine off landings, and best glide speed to achieve the "longest distance" are not the same technique for all gyros. The angle to the left wing from the pilot eyes is around 5.4 degrees. The heavier the aircraft is, the higher the airspeed must be to obtain the same glide ratio. A 5 deg angle (glide path) gets you 1909 feet farther while (just kidding). The 7GCBA (ag spray plane) is certified to 2400lbs (I admit I know nothing about it's structure). 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. What else should I plan for, in checking this? Vy in your airplane is 69 mph. Useful Load: 550 lbs. Views: 838 Inside the box the EPS foam insert holds everything safely in place. 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. Bellanca introduced two designs with close connections to the Citabria: The 8KCAB Decathlon and the 8GCBC Scout. Rolls are okay, though and loops. Use tab to navigate through the menu items. 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. How much does a Citabria cost? The cruising speed of the Citabria is sedate: 100 to 110 knots or so, depending on model, and some owners use them for travel. I would really appreciate if you could help me out. Usable) Oil Capacity: 8 quarts Baggage Capacity: 100 lbs. We purchased it from Doug Cline in 2019. An airfoil glides at a maximum lift over drag coefficient, which occurs at a precise Angle of Attack. Designed for flight training and personal use, it entered production in the United States in 1945. Brian; Not airspeed Joe, Angle of Attack. The engine is a Lycoming Model O-235-K2C and is rated at 118 horsepower. I am all about learning so help me out here. 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. Though the Decathlon went out of production within a decade of its introduction, this was not due to any fault in the design, but rather to the slump in general aviation in the United States at the end of the 1970s and the beginning of the 1980s. Pretty impressive. 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. [2] It was never put into production at Champion nor by Bellanca which acquired the company and designs only a short time later. tan(glide angle)=alt/distance. A C172 w 9.5/1 glide ratio (L/D) has a 6.01 deg. The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. The winds would have to be factored in as well. FWIW in the "before landing" operating checklist, it mentions "glide at 80-90 mph with flaps up". You are using an out of date browser. In GA aircraft, the speed is given in reference to the max weight. Variations in aircraft weight do not affect the glide angle . The fuel tanks are vented together with the vent located on the left wing. The Citabria design based on the Aeronca 7AC Champion. Thus, the only remaining variable left to change our lift is velocity (V), or airspeed. Airspeed-65 MPH recommended (60 MPH minimum) 2. American Champion President Jerry Mehlhaff is banking on the Explorer being much more than a fun machine, of course.
