VOR Flashcards
What is the frequency band of a VOR?
108-117.975MHz
What is the principle of operation for a VOR?
Phase difference or comparisson
What is the maximum angular displacement for a VOR and what is it called?
5 degrees - half scale deflection
A DME has a higher pitched tone of 1 350 Hz for its morse code identifier, and produces one at least every X seconds.
40
To enter a holding pattern based on a VOR/DME fix, which entry sectors are permissible when following a DME arc entry track? Sectors..
=1
=2
=3

In a CVOR (conventional),
What is the reference phase?
What us the variable phase?
What direction does the signal travel?
FM
AM
Clockwise
In a DVOR(doppler),
What is the reference phase?
What us the variable phase?
What direction does the signal travel?
AM
FM
Anti clockwise
A pilot is tracking inbound to a VOR on a designated radial using the HSI. The VOR ground station is located in an area with varying terrain and man-made obstructions. The pilot notices that the CDI is fluctuating slightly, even though he/she is constantly and accurately tracking inbound to the station and there is no apparent wind effect.
What is the term used to describe these fluctuations?
Scalloping
Whats a testing VOR called?
VOT
If the signal strength drops to less than blank%, then the VOR turns off.
85%
If the signal strength drops more than blank%, then the VOR turns off.
15%
How many degrees is full scale deflection on a VOR?
10 degrees
What flag appears when you are on the reciprocal of the VOR?
TO
What do you have to add to an RMI?
Deviation
Where is the aircraft located on the needle?
The tail
