What is a VOR? What frequency range and band is it in?
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.

How does an aerofoil work?
How does an aerofoil work?
An aerofoil is a body shaped to produce an aerodynamic reaction (lift) perpendicular to its direction of motion, for a small resistance (drag) force in that plane. It achieves this by accelerating the flow passing over it, and decelerating the flow passing under it. This change in velocity causes a change in pressure, which in turn generates lift.
If you are at the locator, on glide-scope, on localiser, but your altimeter is reading 500ft high what could be the cause of this?
If you are at the locator, on glide-scope, on localiser, but your altimeter is reading 500ft high what could be the cause of this?
False glide slope.

What is a turbo fan?
What is a turbo fan?
A turbofan is a type of jet engine, similar to a turbojet.
It essentially consists of a ducted fan with a smaller diameter turbojet engine mounted behind it that powers the fan.
Part of the airstream from the ducted fan passes through the turbojet where it is burnt to power the fan, but the majority of the flow bypasses it, and produces most of the thrust. They are mainly used commercially because they are highly efficient and relatively quiet in operation.
What are the advantages of fuel injection vs a carburetor?
What are the advantages of fuel injection vs a carburetor?
Fuel injection provides:
-
Fuel free from vaporization ice
-
Better economy through metered delivery
-
More responsive and efficient engine
-
Less maintenance
On a tapered wing, where would the stall occur first?
On a tapered wing, where would the stall occur first?
At the tip as downwash and spanwise flow effect the angle of attack at each section, but because of the tapered wing the effective angle of attack near the tips is greater than that near the center.
What is ACA/H? What ACA/H did you use? Why do we have an ACA/H?
What is ACA/H? What ACA/H did you use? Why do we have an ACA/H?
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.
