Does the N1 compressor produce thrust?

Does the N1 compressor produce thrust?

Yes, with the modern high bypass turbofans the N1 compressor works as a huge propeller, it takes a big mass of air and gives it a relative small acceleration.

Around 70% of the air will bypass the core of the engine, only 30% of air will be compressed further and will eventually go through the combustion chamber.

If you have a fire from the engine in the Warrior, what do you do?

If you have a fire from the engine in the Warrior, what do you do?

On the Warrior, I would perform the following items:

throttle closed mixture closed fuel selector off fuel pump off magnetos off (mayday + 7700 if time permits) and check if fire is out heater defrost off batt alt switches off top door latch unlatch seat belts erect secure and make a forced landing

What performance category was your last aircraft? How are airplanes classified?

What performance category was your last aircraft? How are airplanes classified?

Note: this question was asked to a candidate with previous Seneca experience, make sure to be able to answer this question for your previous aircraft type.

Seneca is class A.

Aircraft are classified according to their Vat.

If in a go-around, which take-off stages will still apply?

If in a go-around, which take-off stages will still apply?

None. The go around procedure is distinct from the take off procedure. You will still have an acceleration altitude, but you will not have a screen height, V1, Vr, V2, flap retraction altitude, etc.

How does GPWS work?

How does GPWS work?

GPWS is a central computer system that receives various data inputs on configuration, (radio altimeter) height/altitude and instrument landing system glide slope deviation and is able to alert the pilot when a dangerous situation is about to occur.

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

What is anhedral?

What is anhedral?

Downward inclination of a wing from the root to the tip.

At what speed does Mach tuck occur?

At what speed does Mach tuck occur?

Mcrit

Does a jet have a critical engine? Why yes or no?

Does a jet have a critical engine? Why yes or no?

No, there is no P-factor (asymmetric blade effect) as on a propeller-driven aircraft.
