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.

VHF Omnidirectional Radio Range (VOR) is defined as VHF Omnidirectional Radio Range, an aircraft navigation system operating in the VHF band.

VOR's are assigned radio channels between 108.0 MHz and 117.95 MHz (with 50 kHz spacing); this is in the very high frequency (VHF) range.

35 ft

For Reference:

• 50ft for Class B or A (<15° AoB at take-off or normal landings)

• 35ft for Class A (dry take-off or steep approach)

• 15ft for Class A (wet take-off)

A wing stalls because the airflow over the wing’s upper surface separates when the critical angle of attack is reached or exceeded. This causes a reduction in the lift generated by the aerofoil

CFM56-7 series with a max takeoff thrust of 27,300lb.

These engines have higher thrust, improved efficiency, and lower maintenance costs than its predecessor, the CFM56-3 series.

The airspeed indicator uses part of the aircraft's pitot-static system to measure and compare the dynamic air pressure between air moving into the pitot tube and static air pressure measured in the case. 

The ASI is calibrated to ISA at MSL and represents the dynamic pressure as indicated airspeed in knots per hour.

ASI errors can originate and vary from:

A stall strip, usually located close to the wing root, causes the airflow to separate at a lower angle of attack and ensures that the wing root stalls before the wing tips.

Note: this question was asked to a candidate with previous Seneca experience, make sure to be able to answer this question for your previous aircraft type.

Seneca is class A.
