You are flying at FL350 and the temperature reads -30°C, is the aircraft at its optimum temperature?
You are flying at FL350 and the temperature reads -30°C, is the aircraft at its optimum temperature?
No because it is warmer, according to ISA temperature should be -55°C
Describe the movement of the center of pressure with varying angle of attack.
Describe the movement of the center of pressure with varying angle of attack.
The Center of pressure position is dependent of the angle of attack. As the angle of attack increases the center of pressure moves closer to the leading edge.
Do airplanes have an optimum C.G.? If yes, where is it?
Do airplanes have an optimum C.G.? If yes, where is it?
Yes, the closer the C.G. is to the rear limit, the less tail down force is required, which means less drag which results in less fuel burn.
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
The speed is too low for an indication.
Explain V1, V2, VR, VMCA and VMCG
Explain V1, V2, VR, VMCA and VMCG
V1 is the decision speed (sometimes referred to as critical engine speed or critical engine failure speed) by which any decision to reject a takeoff must be made.
V2 is the takeoff safety speed which must be attained at the 35 ft height at the end of the required runway distance. This is essentially the best one-engine inoperative angle of climb speed for the airplane and is a minimum speed for flight in that condition until at least 400 ft above the ground. V2 shall be at least 1.1 times VMCA, and no less than 1.2 times VS.
Vr is defined as the speed at which the rotation of the aircraft should be initiated to takeoff attitude.
VMCA is the minimum control speed in the air and is defined as the minimum speed, whilst in the air, that directional control can be maintained with one engine inoperative (critical engine on two engine aerolanes), operating engine(s) at takeoff power and a maximum of 5 degrees of bank towards the good engine(s).
VMCG is the minimum control speed on the ground and is defined as the minimum speed, whilst on the ground, that directional control can be maintained, using only aerodynamic controls, with one engine inoperative (critical engine on two engine airplanes) and takeoff power applied on the other engine(s).
