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.
What are the problems associated with icing?
What are the problems associated with icing?
Drag penalties (additional weight)
Less controllability
What is Vs?
What is Vs?
Stall speed is defined as the minimum steady flight speed at which the airplane is controllable.
Why do jet aircraft fly as high and fast as possible?
Why do jet aircraft fly as high and fast as possible?
Because the air is less dense thus the TAS is higher for a given power setting and for this reason modern jet aircraft are designed to be most efficient at high altitude.
If you are flying your light twin, how would you ensure minimum obstacle clearance if your engine fails on take off? How would you do this, or, where can you find the relevant information?
If you are flying your light twin, how would you ensure minimum obstacle clearance if your engine fails on take off? How would you do this, or, where can you find the relevant information?
In the airplane documents, as the airplane is certificated regarding performance to be able to fly blue line speed (or Vyse) in this situation, so I would climb at this speed to ensure minimum obstacle clearance.
What is profile drag?
What is profile drag?
Profile drag, also known as pressure drag or form drag, is the drag caused by the separation of the boundary layer from a surface and the wake created by that separation.
It is primarily dependent upon the shape of the object and increases directly with speed as the faster an aircraft moves the more air molecules collide with it.
What is an isobar?
What is an isobar?
A line on a meteorologic chart that joins places of equal sea level pressure (QNH).
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
The speed is too low for an indication.
What do you prefer, a high or low wingload?
What do you prefer, a high or low wingload?
The assessor was trying to get to the approach where you need flaps and slats to increase S (lower wingload) in order to be able to fly a lower speed.
How accurate are NDB's?
How accurate are NDB's?
NDB’s are stations emitting a signal. There is nothing for them to be accurate about. ADF's on the other hand, when tuned to an NDB need to be accurate within +/- 5 degrees.
