What is the movement of the center of pressure during/approaching a stall?
What is the movement of the center of pressure during/approaching a stall?
Center of pressure moves forward when approaching a stall.
Why will a jet usually not fly at 41.000 feet?
Why will a jet usually not fly at 41.000 feet?
Because of the distance which has to be covered to reach 41.000 feet which may not be convenient for a short flight.
On long flights it is more typical to fly at 41.000 feet when the aircraft weight and performance allows.
If you climb to FL300 at a constant IAS of 250kts, what would happen to the TAS?
If you climb to FL300 at a constant IAS of 250kts, what would happen to the TAS?
TAS will increase.
What is anhedral?
What is anhedral?
Downward inclination of a wing from the root to the tip.
Why is a great circle the shortest distance between two points?
Why is a great circle the shortest distance between two points?
The track changes constantly.
Why don’t you want to fly your Seneca into a thunderstorm?
Why don’t you want to fly your Seneca into a thunderstorm?
Due to the structural damage that may occur in thunderstorms, due to hail, severe turbulence and severe windshear.
Besides that, lightning strikes may cause damage to electrical systems and severe icing may occur.
Describe the take off segments.
Describe the take off segments.
1st segment starts at screen height and finishes at gear retracted.
2nd segment starts when the gear is retracted and finishes when acceleration alt is reached (min. 400ft max 1000ft) speed V2.
3rd segment starts at acceleration alt, minimum 400ft, and finishes when the flaps are retracted.
4th segment starts when the flaps are retracted, MCT is set and finishes at the 1500ft.
Can VMCG be lower than V1? Explain.
Can VMCG be lower than V1? Explain.
Yes, VMCG has to be equal to or less than V1 to ensure the aircraft could maintain runway heading having suffered an engine failure at or above V1 when the aircraft is committed to takeoff.

What is N1, N2, EGT and EPR?
What is N1, N2, EGT and EPR?
N1= Low pressure compressor spool or fan rotation speed. Usually expressed as a % of Max N1.
N2= High pressure compressor rotation speed.
EGT= Exhaust gas temperature, indicates the temperature at the first stage of the turbine, which is the most critical temperature in the engine.
EPR= Engine pressure ratio of the inlet to the jet pipe, displayed on the EPR gauge to use as a parameter for setting engine thrust
