Another big influence is the antenna pattern of the antenna on the
aircraft. Fuselage, wing and empennage are the blocking structures of
course. If you want I can have a look and get you some typical data
for structure blocked signal loss.
A lot of aircraft have a seperate GS antenna in the
Thinking of most GA and business aviation aircraft I know the NAV
antenna (VOR/LOC/GS) is always located on the vertical tail, just below
the horizontal tail with a cross or t-tail and on top of the vert. tail
with a low hor. tail. These are usually two antennas, one on each side
of the
For GA (what I have handy right now):
The good old Garmin 400 series: VOR/LOC:-103.5dBm, GS:-87dBm
Avidyne (EntegraII): VOR: 5uV, LOC and GS: 10uV

The Avidyne is TSO minimums if I remember correctly. Their

The nav.dat file contains 'range' in nm for the nav-aid.

Perhaps you could use some heuristic to create a reasonable power level to
meet the published range?

Oh I see then, my bad, I was not aware of this fact. Of course, the

determine the difference easily.
For NDB-s it is more easy. The short range ones are on or
Hi there,
I'm about to start implementing navradio signal propagation, and I'd like to
know from anyone who has experience with this type of radios whether this spec
sheet performance is typical for most receivers including airline big iron, so
that I should hardcode or not the values.
