Vref = 1.3 x Vs0 (stall speed in the landing configuration).

OM = DOM + crew and fuel

For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.

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.

Yes.

There are permanent jet streams in the...

A wing tip is the part of the wing that is the most distant from the fuselage of a fixed-wing aircraft.

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.

New York to London (flying east) would take less time because of the Polar front westerly jet stream.

Fusible plugs offer protection from tire blowouts caused by thermal expansion that is generated in the tire under extra hard braking conditions.

1. Unload. Make sure you are no longer 'pulling G's'

2. Roll wings level

3. Power Reduce the power to avoid overspeeding.

4. gently pull back on the control wheel to ease out of the dive.

When slowed down to a safe airspeed apply throttle as needed.

(N.b.: Do not confuse a spiral dive with a spin)
