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.
What setting would you set the trim to for long range cruise?

What is a yaw damper?
What is a yaw damper?
Boots on the leading edges inflate (6 seconds) to break the ice dissipating it into the airflow.
Powered by the gyro pressure system.

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.
What is departure?
What is departure?
Departure is an east-west distance along a parallel line of latitude, other than the equator.
Departure is calculated by: Change of longitude(minutes) x cosine of latitude.
On A high wing anhedral airplane, like a BAE146, and a high wing straight winged aircraft like a Fokker 50, why they don’t have dihedral wings if it has so many advantages?
On A high wing anhedral airplane, like a BAE146, and a high wing straight winged aircraft like a Fokker 50, why they don’t have dihedral wings if it has so many advantages?
A high wing location like the BAE and the Fokker give a natural stable contribution.
This is because the Center of Gravity is underneath the wing, therefore when disturbed the C.G. provides a positive momentum opposite to the distortion.
What navigational instruments does the Boeing 737-800 have?
What navigational instruments does the Boeing 737-800 have?
IRS / GPS / VOR / DME
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.
What is a high bypass ratio engine?
What is a high bypass ratio engine?
In a high bypass design, the vast majority of the thrust is derived from the ducted fan, rather than from combustion gases expanding in a nozzle.
A high bypass ratio provides a lower thrust specific fuel consumption (grams/sec fuel per unit of thrust in kN using SI units), especially at zero velocity (at takeoff) and at the cruise speed of most commercial jet aircraft.
