A: interference from other transmissions and is maximum at dusk when east of the NDB
B: skywave distortion of the null position and is maximum at dawn and dusk
C: static activity increasing at night particularly in the lower frequency band
D: the effect of the Aurora Borealis
A: The range is limited to the line of sight.
B: Aircraft height is not limiting for the reception of signals from the NDB.
C: The range of an NDB will most likely increase at day time compared to night time.
D: The transmitter power of the NDB station has no affect on the range.
A: height error – station interference – mountain effect
B: static interference – station interference – latitude error
C: static interference – night effect – absence of failure warning system
D: coastal refraction – lane slip – mountain effect
A: 100 metres.
B: 1000 metres.
C: 10 metres.
D: 1 metre.
Given: W/V (T) 230/ 20 kt, Var. 6E, TAS 80 kt What relative bearing from an NDB should be maintained in order to achieve an outbound course of 257(degrees)(M) from overhead the beacon?
