The weight of an aircraft is applied at the CG. The lift at the CP. The relative position between these 2 points determines the stability of the aircraft. For an Aircraft with a tail surface, a CG in front of the CP constitutes a stable system, while a CG behind the CP an unstable system.

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

Anhedral:

compensates for the wing sweep improves roll maneuverability

Apply opposite aileron to the direction of the roll.

-15°C

because:

-2°C per 1000 feet gives -30°C.

ISA: 15°C at sea level - 30°C = -15°C at FL150

NDB’s are stations emitting a signal. There is nothing for them to be accurate about. ADF's on the other hand, when tuned to an NDB need to be accurate within +/- 5 degrees.

Dihedral provides:

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

Contingency fuel is carried to account for additional enroute fuel consumption caused by wind, routing changes or ATM: ATM/CNS restrictions.

Swept wings have:

• Poor lift qualities

• Higher stall speeds

• Speed instability at low speeds

• A wing-tip stalling tendency
