What is the date the airplane stall warning invented?
In the mid-1940s, Greene developed the first practical way to warn the pilot of the aerodynamic stall. His first design and apparatus included threaded bolts, a bicycle horn and other odd components, all powered by flashlight batteries. Greene filed his device for a patent in 1944, and the patent was issued in 1949. In order to develop his design, Greene founded the Safe Flight Instrument Corporation in White Plains, NY, in 1946. There, he refined and marketed the stall warning indicator.
When During an approach to a stall an increased load factor will cause the airplane to do what?
stall at a higher airspeed.
Was the Airplane invented in AFrica?
NO, the airplane was not invented in Africa.
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).
What year was the airplane invented answers?
The first airplane was invented in 1903
What colour are the warning lights of an airplane?
Red
Who has created airplane?
The Wright Brothers invented the airplane.
What is the effect of stall on an airplane?
When an airplane stalls, the wings lose lift for a brief period. This makes the airplane pitch down sharply to regain airspeed and resume flying.
When was the paper airplane invented?
The paper airplane was invented in 1909 by an American named Jack Northrop.
What year was the airplane invented in?
The airplane was invented in the late 1890's. The first recognised flight was in 1903.
Who invented the airplane during the Industrial Revolution?
The Wright brothers invented the airplane during the Industrial Revolution.
The wright brothers invented the airplane in what year?
