On A high wing anhedral airplane, like a BAE146, and a high wing straight winged aircraft like a Fokker 50, why they don’t have dihedral wings if it has so many advantages?
On A high wing anhedral airplane, like a BAE146, and a high wing straight winged aircraft like a Fokker 50, why they don’t have dihedral wings if it has so many advantages?
A high wing location like the BAE and the Fokker give a natural stable contribution.
This is because the Center of Gravity is underneath the wing, therefore when disturbed the C.G. provides a positive momentum opposite to the distortion.
What are TORA, TODA, ASDA clearways, stopways, and screen heights?
What are TORA, TODA, ASDA clearways, stopways, and screen heights?
TORA= Takeoff Run Available, the length of runway declared available and suitable for the ground run of an aeroplane taking off.
TODA= Takeoff Distance Available, the length of the take off run available (TORA) plus the length of the clearway, if available.
ASDA= Accelerated Stop Distance Available, the length of the takeoff run plus the length of the stopway, if available.
A clearway is an area beyond the paved runway, free of obstructions and under the control of the airport authorities. The length of the clearway may be included in the length of the takeoff distance available (Take Off Distance Available (TODA)). For example, if a paved runway is 2000 m long and there are 400 m of clearway beyond the end of the runway, the takeoff distance available is 2400 m long.
The stopway is an area beyond the runway which can be used for deceleration in the event of a rejected takeoff.
Screen height: TODR is the distance from the brake release point to the point where the aircraft gains a height of 35 ft above the ground. This 35 ft is what we call the screen height. While 35 ft is the screen height for class A airplanes, it is 50 ft for class B airplanes.
On a wet runway, the screen height is reduced to 15 ft.
