SARON SAMRA Radio Aids and Flight
Planning UPDATED ACTUAL Questions
and CORRECT Answers
What is "skip zone"? - CORRECT ANSWER - space between ground wave coverage and
sky wave return to earth.
distance between transmitting antenna and point sky wave returns to earth? - CORRECT
ANSWER - Skip distance
what happens to propogation of ground radio ground waves as frequency increases. - CORRECT
ANSWER - attenuation INCREASES to provide LESS reception distance.
how does single sideband SSB increase transmission power? - CORRECT ANSWER -
eliminates one sideband and carrier wave. carrier is reinserted by receiver.
How are SELCAL tones generated? - CORRECT ANSWER - in the ground station coder
and are received by a decoder in the airborne receiver
How does a VOR work? - CORRECT ANSWER - Depends upon a phase difference
between two signals received simultaneously from a ground station.
VOR airway radial tolerance maintained by NAV Canada. - CORRECT ANSWER - +-
3.0 degrees
What is the minimum reception distance and height for a VOR signal assuming no interference?
- CORRECT ANSWER - 40nm at 1000 ft
dual VOR receiver tolerance - CORRECT ANSWER - +- 4° ground, +-4° air
, Tolerance for VOR and DME receivers at VOR check points are... - CORRECT
ANSWER - +- 4 degrees and .5 nm
Abeam a VOR station the CDI is fully deflected and there is no TO/FROM indication. -
CORRECT ANSWER - Crossing a radial 90 degrees to the one selected on the OBS.
What measures the time difference between airborne transmission and ground reply of two
matched signals on different freqs? - CORRECT ANSWER - Distance Measuring
Equipment (DME)
Can civilian aircraft equipped with DME obtain info from TACAN? - CORRECT
ANSWER - yes - select paired VOR freq on LO chart.
DME greatest slant range error? - CORRECT ANSWER - high altitude short distance
ILS localizer provides signal coverage to what? - CORRECT ANSWER - 35 ° and 10 nm
ILS localizer signal is reliable to 10° splay between... - CORRECT ANSWER - 10 and 18
nm
how many degrees is a full scale VOR indication? - CORRECT ANSWER - 10 degrees
how many degrees is a full scale ILS/LOC indication? - CORRECT ANSWER - 2.5°
beam depth of ILS glide path? - CORRECT ANSWER - 1.4 °
When the 3 letter identifier for the localizer begins with an X - CORRECT ANSWER -
The localizer alignment exceeds 3° from the runway heading.
