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.

Low pressure weather, unstable weather.

The distance from the datum to the point at which the weight of a component acts.

The critical angle of attack is the angle of attack which produces maximum lift coefficient.

This is also called the "stall angle of attack".

Dangers of flying into thunderstorms:

Severe wind shear and turbulence (with a risk of structural problems, loss of altitude, loss of airspeed) Severe icing Hail Lightning strikes (with a risk of damage to electrical systems) Radio Communications and Navigation interference from static electricity in thunderstorms

A line of shortest distance between two points on a sphere.

Dihedral provides:

Lateral stability (during a roll) Wing clearance, wingtip to ground has more space

Mach tuck is a nose-down pitching moment experienced as an aircraft passes Mcrit.

Mach tuck is a form of longitudinal instability that is caused by the centre of pressures rearward movement (caused by the shock wave) behind the centre of gravity.

Enhanced Ground Proximity Warning System, provides a greater level of detection than GPWS.

EGPWS is capable of ‘looking ahead’ to identify potential risks on the aircraft flight path as it includes a terrain and obstacle database.

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.
