anhedral is the downward inclinitation of the wing from the root to the tip.

Volume of litres x Specific gravity = weight in kg

A moving stabilator allows for wider operating range of the control surface, which is of great importance in aircraft with a large range of operating speeds.

Compared to a fixed horizontal stabilizer, when trimmed, the moving stabilitor will produce less drag, reducing fuel consumption.

Occluded fronts are formed during the process of cyclogenesis when a cold front overtakes a warm front. When this occurs, the warm air is separated (occluded) from the cyclone center at the Earth's surface.

Occluded fronts usually form around mature low pressure areas.

A METAR is an observation of the actual weather given by a meteorological observer at that aerodrome.

L = 1/2 * rho * Cl * A * V^2

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.

For a commerical aeroplane: During take off. At this point the aircraft has it it's maximum weight, and accelerating in the vertical plane requiring the highest ammount of lift to counteract the weight.

Drag penalties (additional weight)

Less controllability

A turbo charger is externally driven by exhaust back pressure turning a turbine which in turn drives a compressor in the induction manifold to increase the air pressure (constant volume, higher pressure) and is controlled by waste gate.

A supercharger is internally driven by the propellor shaft to compress mixture and is controlled by RPM.
