The glide ratio for the P-40 with the power off is approximately 4% feet forward to 1 foot down at a speed of 150 mph with wheels and flaps up and no overload. In other words, from 5280 feet altitude you can glide about 4 1/2 miles. In an emergency, keep your gliding speed at 150 mph by controlling the angle of your glide. Never let your speed fall below 140 mph. Don't make any turns steeper than 45'.

When practicing long power-on glides, maintain a manifold pressure of at least 20" Hg. Clear your engine every 2 or 3 minutes to keep the plugs from fouling and the engine from becoming too cold. Don't let your coolant temperature fall below 850. When gliding in for a landing use your trim tabs to establish an indicated airspeed of about 110-115 mph.

The stalling speed of the P40 is 'approximately 84 mph with wheels and flaps clown, about 90 mph with wheels and flaps up, (These speeds vary slightly among individual airplanes.) But you can stall the P-40 at any speed, in any position, if you don't coordinate your controls properly. If a high-speed stall develops it usually snaps the airplane. Unless you ease back pressure on the stick immediately, the plane goes into a spin. Avoid high-speed stalls. They are dangerous to you and to the airplane.

Low-speed stalls, on the other hand, are as safe as they were in your AT-6 and are an important part of your P-40 training. Learn lowspeed stalls with wheels and flaps up, wheels and flaps down, only wheels down and only flaps down. Low-speed stalls help you to get the feel of your airplane. If you stall in an unusual position (like the top of a loop or Immelmann) retard the throttle, neutralize the stick and rudder, and wait until the nose is well down before starting recovery. Do not practice stalls below 8000 feet; you may not have room to recover.
