Side bands are often used with AM propagation. An advantage of using sideband transmissions is-
(A) external noise and interference is reduced
(B) the carrier dose not have to be so powerful
(C) different information can be transmitted simultaneously on both bands
(D) all of the above

The VOR operates on the principle of
Frequency differential
AM
phase differential
FM

A common error on both the VOR and NDB is the?
vertical polarisation
night effect
costal refraction
terrain effect

VOR radials are calibrated to magnetic variation ?
At the station installation
at the aircraft
midway between the station
at the nearer pole

An error or limitation commonly associated with the vor is?

co channel interference
coastal refraction
night effect
site error

Aircraft bonding refers to

At ranges greater then line of sight, the type of radio wave propagation on which the ADF/NDB
systems relies on is the

The direct wave
The sky wave
The ground wave
a combination of ground and sky waves

Bending and scalloping are terms used when describing

When selecting a DME frequency you are

The ADF sense antenna

resolves the 180 degree ambiguity
fine tunes the NDB frequency
identifies the maximum signal position
identifies the null position

An advantage of SSR over primary radar is the return signal ?

is reflected more strongly by the target
allows contouring of the weather returns
is not subject to attenuation
may contain coded information

An advantage of SSR over primary radar is that the return signal.

is reflected more strongly by he target
allows countering of the weather returns
is not subject to attenuation
eliminates unwanted returns

The error or limitation commonly associated withe the NDB/ADF

vertical polarisation
ground station error
scalloping and bending
terrain effect

At ranges up to line of sight the type of radio wave propagation on which the NDB/ADF system relies on is the ?

direct wave
sky wave
ground wave
combination of ground and skywave

The ADF loop antenna

resolves the 180 degree ambiguity
fine tunes the ndb frequency
identifies the maximum signal position
identifies the null position

HF radio waves primarily propagate by-

ground waves
diffracting ground waves
direct waves
single and multi hope sky waves

An ILS displays full deflection
