Error associated with the NDB/ADF is
Quadrantal error
NDB station radiates a signal which is
Omni directional
NDB signal received by adf in ac with fixed card adf. Nav info presented as
A relative bearing to the station
In a vertical gyroscope at the South Pole
Drift and topple due earth rate rotation will be zero
In a horizontal axis gyro at the South Pole
Drift will be max topple will be zero
On a polar stereographic chart, meridians appear as
Straight lines
In an inertial navigation system (INS), compensation for earth rate rotation must be applied
According to a specific latitude
In an INS, compensation for transport rate must be applied
According to aircraft speed over the ground
In an INS, the platform on which the accelerometers are mounted must be aligned with
True north
FYI CP position is determined by the GSO and GSH from CP, time to the CP (GSO) has no influence on the position of the CP
Ok???
Coastal refraction is an error which results in
NDB signals bending toward the coast when approaching an island station from over water at an acute angle to the coast
A Doppler VOR installation has the advantage of reducing errors associated with
Obstructions in the vicinity of the site
The purpose of the annunciator in the gyrostabilised remote indicating compass system is to indicate
That the mag detector unit and gyro are correctly aligned and synchronised
A horizontally polarised radio signal is best received by a
Horizontal antenna
A machmeter is subject to
Pressure and instrument error
