What is Point of No Return (PNR)?
What is Point of No Return (PNR)?
The point during a flight at which an aircraft is no longer capable of returning to the airfield from which it took off due to fuel considerations.
Beyond this point the aircraft must proceed to some other destination.
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.
Where is thrust produced in a gas turbine engine?
Where is thrust produced in a gas turbine engine?
Mostly in the fan, but also from the exhaust nozzle duct.

The tailplane of a Seneca has an elevator and a trim tab, what does a Boeing 737 have?
The Boeing 737 has an all moving horizontal stabilizer.
How do you get out of a spiral dive on a Cessna?
How do you get out of a spiral dive on a Cessna?
-
Unload. Make sure you are no longer 'pulling G's'
-
Roll wings level
-
Power Reduce the power to avoid overspeeding.
-
gently pull back on the control wheel to ease out of the dive.
When slowed down to a safe airspeed apply throttle as needed.
(N.b.: Do not confuse a spiral dive with a spin)
At high altitudes, what speed do aircrafts climb on?
At high altitudes, what speed do aircrafts climb on?
Mach number
If you are outside the range of any VOR’s/NDB's, how does the aircraft know where it is?
If you are outside the range of any VOR’s/NDB's, how does the aircraft know where it is?
Via INS/IRS/GPS

Why is anhedral used instead on some aircraft?
Why is anhedral used instead on some aircraft?
Anhedral:
compensates for the wing sweep improves roll maneuverability
What is the advantage of a variable pitch propeller? Why not have a fixed propeller?
What is the advantage of a variable pitch propeller? Why not have a fixed propeller?
A variable pitch propeller provides an optimum angle of attack for the propeller blades for a longer range which reduces fuel usage. Fixed pitch propellers are easier to produce and maintain, but reach maximum efficient at only one specific airspeed.
