Does windshear show on the weather radar?
Does windshear show on the weather radar?
No
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.
What is the speed of sound at sea level according to ISA?
What is the speed of sound at sea level according to ISA?
662 kts
Local speed of sound = 39 x √(Temperature in Kelvin)
15°C in Kelvin is (15 + 273) = 288
So the local speed of sound = 39 x √288 = 662 kts
What would you do in the event of an engine failure below V1, and what would your initial actions be?
What would you do in the event of an engine failure below V1, and what would your initial actions be?
Assuming I'm performing single pilot operations:
-
power idle,
-
max brakes (and reversers if available),
-maintain directional control using rudder input,
-
After coming to a full stop set parking break.
-
Inform ATC 'Stopping'.
-
Initiate the appropriate process to diagnose the problem (ECAM, NITS DODAR, checklists....).
-
When performing multi pilot operations the actions performed by me will depend with my current role: PF, PM and/or CM1 CM2.
You are flying in a straight line on an airway when your company calls and requests you to return to base, what will you do first?

Inform ATC.
Where does the wing stall first on a typical SEP Aircraft (Cessna, Tecnam, ...)?
Where does the wing stall first on a typical SEP Aircraft (Cessna, Tecnam, ...)?
At the wing root. This is a property of rectangular wings, but it's also common to find close to the wing root devices that make it so that the wing root stalls first.
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.
What is induced drag?
What is induced drag?
Induced drag and its wing tip vortices are a direct consequence of the creation of lift by the wing.
Since the Coefficient of Lift is large when the Angle of Attack is large, induced drag is inversely proportional to the square of the speed whereas all other drag is directly proportional to the square of the speed.
The effect of this is that induced drag is relatively unimportant at high speed in the cruise and descent where it probably represents less than 10% of total drag. In the climb, it is more important representing at least 20% of total drag. At slow speeds just after take off and in the initial climb, it is of maximum importance and may produce as much as 70% of total drag.
Finally, when looking at the potential strength of wing tip vortices, all this theory on induced drag must be moderated by the effect of aircraft weight. Induced drag will always increase with aircraft weight.
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
While climbing with a SEP, in what temperature range can carb icing occur?
While climbing with a SEP, in what temperature range can carb icing occur?
Carb icing can occur with temperatures as high 30°C and humidity as low as 50%, but it is more likely when below 20°C and high humidity, especially during low power settings.
