Decision altitude (precision), the altitude at which a decision must be made during an ILS, MLS, or PAR instrument approach to either continue the approach or to execute a missed approach.

Basic Empty Mass (BEM) is the mass of the aircraft with the basic equipment, unconsumable fluids and unusable fuel and oil.

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

Airplanes can get uncontrollable during windshear.

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

Lift is the component of the total aerodynamic force perpendicular to the relative airflow.

Lift is generated when a streamlined body, such as an aerofoil, is placed in a flow of air.

The angle between between the chord line and the aircraft's longitudinal axis. It's a fixed angle for wings, but variable for variable incidence tailplanes.

662 kts

Local speed of sound = 39 x √(Temperature in Kelvin)

15°C in Kelvin is (15 + 273) = 288

So the local speed of sound = 39 x √288 = 662 kts

Fuel injection provides:

• Fuel free from vaporization ice

• Better economy through metered delivery

• More responsive and efficient engine

• Less maintenance

Dihedral is the upward inclinitation of the wing from the root to the tip.
