If you can, try a payware c172 in x plane 11, do it! (REP C172 or Airfoillabs) I flew a pattern in vr and it was like flying the real cessna!! Besides Its very simple to make a comparison, grab a power off landing in hd in youtube and take a look at the vertical speed indicator, the cessna glide around 600 fpm, on turns increase to around 900 Best glide airspeed is the speed that maximizes the L/D ratio, and this maximum value is known as L/D max. The maximum L/D ratio (L/D max) of a Cessna 172 is about 9, so its glide ratio is about 9:1 - for every 9 units traveled forward it will lose 1 unit of altitude. So, it will glide about 9,000 feet for every 1,000 feet of altitude available

According to Cessna 172 POH the speed for max range with power off, or glide speed, is 65, and achieved at the best L/D ratio. However with power on the speed for max range will be around 75 .com, Cessna 172 talk 24/7. You are not logged in. Cessna 172 (69 kts) and if I enter 80 FF assumes knots. While your glide RATIO will be the same, number of minutes at glide will be greater so head or tail wind will have more effect. Top #342310 - 06/08/17 04:11 PM Re: Maximize Glide Performance Curious1 Gold Pilo Most GA airplanes, whether they're a Cessna 172, or a Cirrus SR-22, glide about 1 1/2 miles for every 1,000' of altitude. So for example, if you're 4,000' above the ground, you'll be able to glide about 6 nautical miles before your wheels are on the ground Therefore, compared to a 172, the glide ratio is only slightly worse but at a 50% higher forward speed and a 50% higher sinkrate. I believe the 172 is 9:1 and the 182 is 10:1. If you have a controllable pitch propeller, you can increase that by about 10%, and if you stop the prop, it increases about 20% (Barry Schiff, Proficient Pilot).. The glide ratio of the C-152 is very similar to that of the C-172, at around 1/10. The C-152 has a smaller wing that the C-172, so even though it is lighter, the glide ratio remains pretty much the same. All of the US manufactured, traditional, GA aircraft seem to have glide ratios around 1/8 (Piper Tri-Pacer) up to around 1/10
In other words, the aircraft will glide horizontally 8 units for every 1 unit of descent. Our default is 10:1; most aircraft fall between 6:1 and 14:1. (A glide ratio of 20:1 might be appropriate for an Eagle riding the wind while a 1:14 ratio is similar to the glide capability of a brick.) Enter the altitude AGL that the glide condition begins This is very similar to that of the 172, except that the glide ratio is closer to 1.4 nm per thousand feet AGL. More importantly though is that the best glide speed does depend on the aircraft weight even though the maximum glide distance does not . And this dependence is quite large—the best glide speed increases 31% between 2100 lb and 3100 lb Glide ratio is determined by dividing the distance covered at a particular airspeed by the rate of descent over a one-minute period. In a trusty Cessna 172 I performed an informal flight test to determine its glide ratio, yielding the following data Math is simple, let's say (optimistically) the glide ratio in your 172 is 9:1. For every thousand feet of altitude AGL, your cone of being able to land someplace is nine thousand feet in radius (18,000 feet in diameter.) I typically cruise at 3,000 feet
Is 15.4 to 1 glide ratio correct or in a safe ball park for a 9a? Seems pretty high? Obviously many factors are involved ie. Weight, altitude, pressure, etc. Seems that by default 10/1 ratio as in C172. Seems to be used. Does anyone have an accurate glide ratio for a 9a, Say at max weight I first heard about this many years ago when Bill Thompson, the chief flight-test engineer for Cessna, told me that stopping the propeller of a Cessna 172 improved its glide ratio by 20 percent. I decided to perform a flight test of my own using a Cessna 182. The 182 has a glide ratio of 9.3:1, which is typical

The best glide with two souls aboard is at 72 knots which, with no wind, will glide 1 1/2 miles per thousand feet of altitude. For cross country, I flight plan for 4 1/2 hours of fuel on board (49 gallons usable) pilot and two passengers, plus 180 pounds of bags. Maximum gross weight is 2550 pounds
The glide ratio is based only on the relationship of the aerodynamic forces acting on the aircraft. The only effect weight has is to vary the time the aircraft will glide for. The heavier the aircraft is, the higher the airspeed must be to obtain the same glide ratio. If two aircraft have the same L/D ratio but different weights and start a. In a Cessna with 7.4:1 glide ratio, it might be prudent to use 1000 minimum safe altitude to consider returning to the field. Remember that the Impossible Turn at 1000 feet becomes an Improbable Turn since it needs at least 240 degrees of turn to line up with the runway - with a tailwind to boot .75:1 at that speed. I'm claiming 8.5:1 and a best glide speed of 110 kt at 1800 lb weight in my POH. The glide performance was much better than that with prop stopped, but it was so hard to get the prop to stop that I would not try that in a real emergency unless I was above 15,000 ft AGL Mathematically (and aerodynamically) speaking, a true 1:1 glide ratio does mean exactly that if you speak in statute miles. In the aviation world, we deal in Nautical miles, and 1 NM is 6000 feet. It makes the math a lot easier. So, the F-16's glide ratio is actually closer to 6000:1000 or 6:1, mathematically speaking (in all honesty, it's a.
Even a Cessna 172 (glide ratio of 20:1 IIRC from the old days) might exceed the fuel economy of a car of the same weight, if it made the most efficient climb to altitude, followed by an unpowered glide. Of course, there are aircraft with glide ratios of 1:80 or 1:100 or more this value is usually of around 0.02 to 0.025 for an aircraft with a glide ratio above 15, 0.03 to 0.04 for aircraft with glide ratios of about 10, and up to 0.1 for some slow bush planes with very low glide ratios
. 01-13-2009, 09:36 PM. Icarus' glide ratio works out to 4.8:1 using statute miles. Roger on the jury struts. The jury strut spacer is a pretty accurate indicator of glide capability. I have tried this from altitude (no wind) and also fly the traffic pattern so the runway is always lower than this spacer I reduced indicated airspeed to 58 knots, halfway between the power-off stall speed (48 knots) and the speed for best glide (68 knots), and then simulated an attempt to restart the engine (check ignition, fuel, and so forth). The instructor commented that my speed was 10 knots low and asked if I knew the speed for best glide A Cessna 172 is a powered aeroplane, it has four seats and an engine between 145 and 230 hp. It is not designed to be a glider. It is heavy, it is cumbersome compared to a sport sailplane - however once at cruising altitude in the event of the eng..
Compared to C172 SP, which also has a 180hp Lycoming engine, the much higher performance shows how much more efficient this plane is (sorry I just like to diss Cessna, no offense to people who like them :P). Glide ratio 13:1. I'd almost call it a glider. I have seen how well the DA20 glides, and it looks like the DA40 is no different LTCTerry on Apr 30, 2017. A typical American training glider has a glide ratio of about 24:1. A modern German counterpart about 33:1. Higher is better. 40 or more to one for single seaters has been common for 30 years or so. An extremely expensive, highly competitive glider today can have a 60:1 glide ratio of a Cessna 172 increased the glide ratio by 20%. A similar increase occurs in the Cessna 150 (and most other light aircraft) which boosts the glide ratio from 8.5 to 10.2, added gliding distance that could convert a potential disaster into a safe landing. Once the prop is stopped, however, lower the nose and accelerate to the normal glide speed best glide - 65 kias (75mph) (full gross weight) carb heat - on (also supplies alternate air) (note gauges) (try re-priming) note wind direction & velocity pick landing site mixture - full rich fuel selector - check/ switch/ both fuel primer - locked magnetos - check all master - on if no restart & time permits maintain best glide squawk 770
All cuff manufacturers claimed the same thing, improved stall performance, better lift over drag ratio, better glide. I asked pilots who had other kits on their 170s and 180s. None could come up with any real advantage. So I called LindAir about the Sportsman kit - they were ecstatic . For the parameters used in this application, a Baron 58 aircraft has a maximum lift-to-drag ratio of about 12.2. This means an unpowered Baron will fall 1 m for every 12.2 m of travel
A good exercise is to examine the glide ratio in your POH and do the math for a 5000ft decent glide. Put yourself at the prescribed distance from the airport, that you should be able to cover, at 5000ft agl, in line with the runway and see where you end up. This will give you a reasonably accurate glide ratio for THAT airplane Glide Slope Ratio The Glide Slope Ratio is a number that indicates how well your designed shoebox glider flies through the air in terms of its forward distance vs. its drop in altitude. Glide Ratio = Horizontal Distance divided by the Change in Altitude The Sportsman STOL wing cuff is a state of the art modification designed to increase light plane utility and safety by increasing the wings efficiency and resistance to stalls and spins. The kit consists of a glove that fits over the wings leading edge, extending approximately two inches forward from the original wing, and further drooping the leading edge This example shows how to perform glide calculations for a Cessna 172 following Example 9.1 in Reference 1 using the Aerospace Toolbox™ software. Best glide calculations provide values (velocity and glide angle) that minimize drag and maximize lift-drag ratio (also called the glide ratio) A modern C 172 has relatively large and sophisticated flaps relative to other similar sized aircraft. The flaps can be used to significantly increase the surface area of the wing. When you extend flaps, you are increasing both lift and drag. This.
D. Explain which of your derived values will allow glide performance predictions for your aircraft and quantify best glide conditions with specific values Lift is proportional to distance and drag, so (L/D)max is proportional to glide ratio (distance/altitude) (Dole et al, 2017, p. 88). For this aircraft the (L/D)max is 13.7169816 I know the glide ratio for the Cessna 172 I fly is 9:1 which is for every 1,000 feet of altitude I will cover about 9,000 feet which is 1.7 miles. so let's say a 737 has a glide ratio of almost double 9:1 like 17:1, if it's 10,000 feet in the air and 32 miles away from LAX , it will actually glide right onto a runway, I find that hard to believe For the C172, the glide ratio is about 9:1, so the descent angle would be about 6 degrees down. The angle of attack would be about 10-15 degrees up, totalling about 4-9 degrees above horizontal. I'm not sure what angle the wings are mounted at. It also depends on the pilot's height and how high the seat is adjusted w.r.t. the cowling This resulted in a TAS and ground speed of 234 kt and a sink rate of 900 ft/min. This is a glide ratio of approximately 26:1. As far as I know the best glide ratio of an A320 is about 16, so the number in the simulation is much too high. Great addon by the way!!! My background: Private pilot licence C172, Aquila 211, Robin 2160 D, Super.

A fully loaded 747 has a glide ratio of 15:1 meaning that it travels 15 feet horizontal for every foot of vertical drop. That means at 35,000 feet it could travel about 100 miles. The new 787 Dreamliner is around 20:1. As a comparison, a Cessna 172 (little single engine plane) has a glide ratio of 9:1 - not as good as airliners The Cessna 172 wing has an aspect ratio of 7.32 while the Dash 8 has a much higher aspect ratio of 12.78. Difference in Aspect Ratio between Cessna 172 and de Havilland Dash 8 Q400. Why would these two aircraft be designed with such a large variation in aspect ratio? The first clue is to look at their respective design cruise speeds Our glide ratio, the ratio between distance over the ground and altitude lost, is equal to our lift-to-drag ratio (1). In order to maximize the distance we travel over the ground in a glide, we must achieve the best possible lift-to-drag ratio (2). We may remember something similar from our study of flight for maximum range where we also must. Both heavy and light glider achieve the same best glide ratio, as shown here, but the heavy glider does so at a higher speed. This is the reason for carrying ballast to improve glide performance when the thermals are strong enough, even though the climb rate suffers. Reply 19th May 2010, 15:57. As I understand it, altitude should not matter when doing these experiments to determine glide ratio. So for example if we are at 10,000 feet, gliding at 90Kt IAS, of course our true airspeed is say 20% higher, but then our true rate of descent is also 20% higher than indicated on our VSI
This data uses the glide ratio of a Cessna 172 (1.5 nm per 1000 ft), which also applies to the Cessna 150. The maps assume no wind, and a lake elevation of 577 ft MSL. NOTE: This map was drawn to a set scale assuming that the scale (6.85 pixels/nm) applies to the entire map. Due to the curvature of the Earth, this causes some slight (~5%) errors • Airspeed - Best Glide 65 KIAS approach and landing in a C172, the (visual) aiming point chosen by the pilot is often an earlier point on the runway than the AIM defined aiming point markings to account for the flare. This technique ensures that the airplan Because of the intricacies involved in training on jet aircraft, the United States Air Force adopted the Cessna Model 172 high-winged monoplane as a basic trainer. The Model 172 was introduced in 1964 as the T-41 Mescalero (Mescalero representing an Apache tribe) and retained all of the form and function of its civilian market product 61 kias with full flaps (until flare) Magneto check max difference during run up check.

Fuel allowance for engine start, taxi and takeoff. 1.4 gallons The Cessna 337 Skymaster is arguably the most commercially successful so-called push-pull attempt, at least in terms of numbers built. And although the 337 Skymaster isn't the most popular twin ever marketed, it's done just fine for itself and has achieved its primary goal: eliminating asymmetric thrust and simplifying the pilot's workload in the event of an engine out
This ratio indicates not only how far an airplane will glide from a given altitude (see Section 21.3.8, Glide Distance), but also, in the case of a propeller aircraft, how far it can fly and, in the case of a jet, how long it can stay aloft. Table 15-18 shows typical values for the maximum L/D ratio for several classes of aircraft Glide approaches For a glide approach and landing we usually assume you still have your flap available to you. Set up your glide at your best ROD speed, and aim 1/3 into the runway. The thinking is that is is better to run off the end of the runway at low speed than not to make the beginning of the runway at a higher speed The glide ratio is mathematically equal to the Lift to Drag (L/D) ratio. In light, single engine aircraft like the C172, a spool up is not really required because the engine is quite small. On large airliners though, the engines produce more thrust and have a lot more going on, so it is usually standard to set the throttles to around 50%. The NACA 65A015 airfoil used on the Cessna 177 was chosen for its laminar-flow characteristics. This airfoil has a much higher drag at low Airspeeds than the NACA 2412 airfoil used on the Cessna 172, so in order to obtain a positive rate of climb the pilot had to use a higher climb Airspeed than was common in the Cessna 172
