What is the coffin corner and why should pilots avoid it?
Answer: Coffin corner is a term used to describe a condition at high altitude when the maximum speed (limited by the spreading of supersonic shock waves) and the minimum (limited by amount of air passing over the wing) are nearly the same.
Where do old planes go to die?
Airplane Graveyard
The Davis-Monthan Air Force Base outside Tuscon, Ariz., is where old planes go to die. More than 4,000 military aircraft are parked on the base, from B-52s to stealth bombers, where they are salvaged for parts and broken down for scrap.
What happens to an aircraft when it stalls?
When an airplane stalls, it’s no longer able to produce lift. When this occurs, there’s an insufficient amount of air traveling under the airplane’s wings to keep it up. As a result, the airplane will drop, thereby reducing its altitude, until the angle of attack is correctly adjusted.
How do you recover a coffin corner?
To recover, you push the stick forward, letting the craft’s nose go down and the speed over the wings increase. You start flying again and can bring the stick back to a straight and (almost) level glide.
Does stalling speed change with altitude?
At higher altitudes, the air density is lower than at sea level. For example, the indicated airspeed at which an aircraft stalls can be considered constant, but the true airspeed at which it stalls increases with altitude.

Can commercial planes stall?
There are there three main scenarios for when a commercial aircraft will encounter a stall. Stalling may also occur when an aircraft has been ordered to ‘go-around’ and abort a landing. The pilot must transition from a low airspeed to a high airspeed but also trim the angle of attack and turn the aircraft.
Why is it called the coffin corner?
The name comes from the “coffin corner” found in Victorian houses (the slang and often refuted term for a decorative niche, or very small ‘corner’, cut into the wall of a staircase landing), because the target area is very small.
Does stall speed decrease with altitude?
Your indicated (IAS) stall speed stays the same because it is not directly affected by density altitude changes. However, your true airspeed stall speed does increase with altitude.
