During what phase of flight is lift the greatest?
During what phase of flight is lift the greatest?
For a commerical aeroplane: During take off. At this point the aircraft has it it's maximum weight, and accelerating in the vertical plane requiring the highest ammount of lift to counteract the weight.
If you only have a compass, which is easier to navigate along: a line of longitude or a line of latitude?
If you only have a compass, which is easier to navigate along: a line of longitude or a line of latitude?
A line of latitude.
Why are NDB powered so that they only have a range between 15-25 miles?
Why are NDB powered so that they only have a range between 15-25 miles?
NDB’s can suffer from a lot of errors.
What is MDA?
What is MDA?
Minimum decent altitude (non-precision), the lowest altitude, expressed in feet above mean sea level to which descent is authorised on final approach or during circle-to-land maneuvering in execution of a standard instrument approach procedure where no electronic glideslope is provided.
If not visual between MDA and MAPt, a Go-around must be initiated.
Do airplanes have an optimum C.G.? If yes, where is it?
Do airplanes have an optimum C.G.? If yes, where is it?
Yes, the closer the C.G. is to the rear limit, the less tail down force is required, which means less drag which results in less fuel burn.
What sort of weather would you find at an occluded front?
What sort of weather would you find at an occluded front?
Low pressure weather, unstable weather.
What errors does an NDB suffer from?
What errors does an NDB suffer from?
NDB errors:
Interference from other NDB’s
-
Static, especially near thunderstorms
-
Night effect Coastal refraction
-
Mountain effect
-
Aircraft quadrantal error
What is DA?
What is DA?
Decision altitude (precision), the altitude at which a decision must be made during an ILS, MLS, or PAR instrument approach to either continue the approach or to execute a missed approach.
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.
Describe the take off segments.
Describe the take off segments.
1st segment starts at screen height and finishes at gear retracted.
2nd segment starts when the gear is retracted and finishes when acceleration alt is reached (min. 400ft max 1000ft) speed V2.
3rd segment starts at acceleration alt, minimum 400ft, and finishes when the flaps are retracted.
4th segment starts when the flaps are retracted, MCT is set and finishes at the 1500ft.
