Navigation
The accuracy depends on:
- The quality of the receiver
- The distance to the transmitter
- The surrounding terrain including high-voltage lines
Accuracy for transmitter and receiver +/- 3 degrees in total. In addition, pilot
inaccuracy of +/- a few degrees must be taken into account.
In the drawing here you can see some transmitter limitations.

VOR transmitters must be able to function correctly up to an angle of at least 40
above the horizontal. Cone of confusion approx. 6 degrees.
We can find the range in NM using the following formula:
1,23*√height in feet
Remember, it is on the VHF band, so line of sight is required
o
This VOR instrument shows that there is 345 to or
from the VOR station.
The aircraft may be on radial 165, but there is a flag
warning, which means that we cannot trust the
display. This may be due to errors in the VOR or
because we are outside its range.
