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

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.

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

A wing stalls because the airflow over the wing’s upper surface separates when the critical angle of attack is reached or exceeded. This causes a reduction in the lift generated by the aerofoil

Lift, Drag, Weight and Thrust.

TAS will increase.

Poor, because the sweep-back design has the effect of reducing the lift capabilities of the wing.

• If no IRS/INS/GPS was available, it’s easier to fly a constant heading (but you will need to apply variation).

• If flying over short distances (as done during your training) the error introduced by flying a rhumb line is insi

A free turbine is a turbine that is not directly connected to the compressor. This allows the compressor to rotate at a different speed than the turbine. Since the turbine speed is coupled with the propeller, this allows for the propeller to be maintained at a constant ideal speed.

Another advantage is that free turbine engines can be designed to be more compact than their single shaft counterparts

Antiskid has a detection system that senses the moment a wheel stops rotating.

Once it senses that the wheel is not rotating, the antiskid system releases brake pressure. This allows the wheel to regain traction with the surface, so that break application can be resumed and prevents complete loss of controllability.
