How does a jet engine/gas turbine work?
How does a jet engine/gas turbine work?
Forward motion forces air into the intake which is a convergent duct where it is compressed (causing a temperature rise).
Fuel is added and combustion takes place increasing the volume. The expanding gasses accelerate to the atmosphere through the exhaust duct nozzle producing a propulsive jet.
When does speed change from IAS to Mach?
When does speed change from IAS to Mach?
At FL260
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.
Why don’t you use carburetor heat on the ground for long periods?
Why don’t you use carburetor heat on the ground for long periods?
Battery power to the starter motors.
What is Vmu?
What is Vmu?
Vmu is the minimum unstick speed.
It is the calibrated airspeed at and above which the airplane can safely lift off the ground and continue the takeoff. Lift-off is not possible prior to reaching this speed.
Vmu is not an operational speed and is established in flight testing only.

How accurate are NDB's?
How accurate are NDB's?
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.
Can a helicopter rotor blade stall?
Can a helicopter rotor blade stall?
Yes
What do you know about carb icing? Would you experience it today?
What do you know about carb icing? Would you experience it today?
Carb icing can occur in the engine induction system and in the carburettor of piston engines.
Regarding the second question, mention the conditions in which carb icing can occur and if it would be possible on that particular day.
Conditions for carb icing: when OAT is between -10 & +30, with high humidity (greater than 40%) and/or visible moisture.
