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.

GPWS is a central computer system that receives various data inputs on configuration, (radio altimeter) height/altitude and instrument landing system glide slope deviation and is able to alert the pilot when a dangerous situation is about to occur.

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.

Yes, VMCG has to be equal to or less than V1 to ensure the aircraft could maintain runway heading having suffered an engine failure at or above V1 when the aircraft is committed to takeoff.

Anhedral:

compensates for the wing sweep improves roll maneuverability

Fuel injection provides:

• Fuel free from vaporization ice

• Better economy through metered delivery

• More responsive and efficient engine

• Less maintenance

Jet engines are designed to achieve their best specific fuel consumption at high rpm, which can only be achieved at high altitudes where the air density is low.

Thrust produced will be low enough to equal the required cruising thrust. Also high altitude gives the best operating conditions for the airframe i.e. minimum drag during the cruise.

Turboprops need relatively dense air for the propellers to work efficiently and at high altitude the density would be too low.

Asymmetric Committal Altitude/Height is the minimum height needed to establish a positive climb whilst maintaining adequate speed for control and removal of drag during an approach to a landing.

In the Seneca at Oxford we used 200ft AGL. At this altitude when continuing for landing you selected the landing flaps (check clear runway, on speed, on altitude, landing clearance received).

You now are committed to land, single engine G/A with flaps 40 and gear down is not possible in a Seneca.
