What are fusible plugs, where are they used, how do they work, why do we have them?
What are fusible plugs, where are they used, how do they work, why do we have them?
Fusible plugs offer protection from tire blowouts caused by thermal expansion that is generated in the tire under extra hard braking conditions.
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.
How do you prevent an aircraft reaching Mcrit?
How do you prevent an aircraft reaching Mcrit?
Decreasing speed, by reducing engine power or pitching up.
What is the height of the tropopause according to ISA?
What is the height of the tropopause according to ISA?
36,090ft in ISA
What are the benefits of a free turbine?
What are the benefits of a free turbine?
A free turbine is a turbine that is not directly connected to the compressor. This allows the compressor to rotate at a different speed than the turbine. Since the turbine speed is coupled with the propeller, this allows for the propeller to be maintained at a constant ideal speed.
Another advantage is that free turbine engines can be designed to be more compact than their single shaft counterparts
What frequency range and band is an NDB in?
What frequency range and band is an NDB in?
Frequency range from 200-1750kHz, medium and low range frequency bands.
What are the forces acting on an aircraft in flight?
What are the forces acting on an aircraft in flight?
Lift, Drag, Weight and Thrust.
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
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.
What is VMBE?
What is VMBE?
The maximum brake energy speed.
It is a function of the gross weight, altitude, temperature, runway slope, wind component, and braking configuration.
V1 must be less than VMBE.
