  1. 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
    (d)
  2. The VOR operates on the principle of
    Frequency differential
    AM
    phase differential
    FM
    Phase differential remember the light house analogy
  3. A common error on both the VOR and NDB is the?
    vertical polarisation
    night effect
    costal refraction
    terrain effect
    Terrain effect
  4. VOR radials are calibrated to magnetic variation ?
    At the station installation
    at the aircraft
    midway between the station
    at the nearer pole
    At the station install
  5. An error or limitation commonly associated with the vor is?

    co channel interference
    coastal refraction
    night effect
    site error
    Site error
  6. Aircraft bonding refers to
    Ensuring an even electrical potential between different parts of the aircraft
  7. 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
    The ground wave
  8. Bending and scalloping are terms used when describing
    Vor
  9. When selecting a DME frequency you are
    Selecting a pulse paired frequency
  10. The ADF sense antenna

    resolves the 180 degree ambiguity
    fine tunes the NDB frequency
    identifies the maximum signal position
    identifies the null position
    Resolves the 180 degree ambiguity
  11. 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
    coded information
  12. 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
    eliminates unwanted returns
  13. The error or limitation commonly associated withe the NDB/ADF

    vertical polarisation
    ground station error
    scalloping and bending
    terrain effect
    Terrain effect
  14. 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
    Direct wave
  15. The ADF loop antenna

    resolves the 180 degree ambiguity
    fine tunes the ndb frequency
    identifies the maximum signal position
    identifies the null position
    identifies the null position
  16. HF radio waves primarily propagate by-

    ground waves
    diffracting ground waves
    direct waves
    single and multi hope sky waves
    single and multi hope sky waves
  17. An ILS displays full deflection
    .5
    .7
    1.0
    1.4
    .7
  18. MLS has the advantage of
    curved approaches
