Who invented airplane stall warning?
the person who invented the airplane stall warning is Leonard Michael Greene.
When During an approach to a stall an increased load factor will cause the airplane to do what?
stall at a higher airspeed.
What is the stall speed of an airplane under a load factor of 4 if the unaccelerated stall speed is 70 knots?
The stall speed of an airplane is inversely proportional to the square root of the load factor. Therefore, with a load factor of 4, the stall speed would be 35 knots (70 knots / √4).
Does the disign of a paper airplane effect it?
Yes, the design of a paper airplane can effect its performance.
What are the flaps on an airplane used for?
The flaps on an airplane are there for two reasons: Drag and lift. As an airplane lines up with the runway and descends, it must slow down. Several things are done to slow down, such as throttle the engines down and lower the gear. However is some airplanes, to slow down and remain slow they must extend the flaps. These cause extra drag, which slows the airplane down. They are usually extended in increments while on approach. The second reason is for lift. As an airplane get slower, the wings get less and less effective, and once it gets slow enough, it may stall. To prevent a stall, airplanes lower flaps. These redirect air downward, pushing the airplane up. This allows it to fly slower, past its "clean" stall speed. (Clean stall speed refers to an airplane's stall speed with no flaps or landing gear extended) Some airplanes can fly nearly 100 knots slower with full flaps. The stall speed with full flaps and landing gear extended is known as "dirty" or "landing configuration" stall speed. This is much slower than "clean" stall speed.
What happens when a flying airplane has less thrust than drag?
It will stall and begin to lose altitude.
What will the angle of attack at which an airplane wing stalls at is do to what?
The plane stall remain the same regardless of gross weight.
What is the effect of uncontrolled climb and descent in an aircraft called?
Stall
Does a hole affect a paper airplane?
The effect of a hole on a paper airplane would depend on the type of paper airplane the hole is on, and where it is on the aircraft.
What control stall margin?
Stall margin is the difference in the critical angle of attack and the angle of attack in which you are operating.Example:Suppose, critical angle of attack= 15°AOA operating in a flight= 5°then, Lift by the wing balances the weight of the airplane with a STALL MARGIN= 10°Stall Margin is being controlled by an angle of attack and the position of flap control..CHEERS!
Why do planes stall?
Because of the airflow suddently stops to flow over the wings and not enough flow to keep te airplane in the air
Why do airplanes stall at times?
The term "stall" describes an airplane that can't produce enough lift to stay in the air. Usually, this means the airplane will descend rapidly and will gain airspeed and lift; thus it will recover from the stall. Pilots practice this because recovering from a stall is important. It is especially important near the ground where there may not be enough time or altitude to recover from a stall, and so the airplane will crash. If you are talking about the enging stalling, it could be the same reasons any engine stall, it either has a fuel problem, an ignition problem or a catastrophic mechanical failure. IF you are talking about the wing stalling, then is is because the wing has exceded the critical angle of attack. quite simply the wing produces no lift and the plane is now falling. the only way to recover is to lower the nose reducing the angle of attack to the relative wind, increase the airspeed to once again to produce lift. Hope this helps.
