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.

A precision approach uses both lateral (from left to right) and vertical guidance. A non-precision approach only uses lateral guidance.

The angle between the chordline and the incoming airflow.

The ratio between the wing span and the mean chord line.

A high aspect ratio is associated with good lift to drag ratio, i.e.: Gliders.

A low aspect ratio is usually associated with fast aircraft, i.e.: Fighter jets.

To varify the nose gear position (up or down).

Drag penalties (additional weight)

Less controllability

Government sources.

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

Stall warning, stick shaker, stick pusher, etc...

Generically we can destinguish between systems that alert the pilot of the impeding stall, like stall the stall warning or stick shaker, and systems that try to correct the situation, like a stick pusher.

A straight line conecting the leading edge with the trailing edge of an aerofoil.
