Why is it that comm radios fail but nav radios do not?

Receivers are simpler than transmitters?

Nav radios fail too! Transmitters are usually less complex than the
matching receiver, but they also handle much more power. More power
means more stress on the components, which in turn leads to a higher
failure rate.

If it's just your transmitter that has failed you have not experienced a
two-way radio communications failure.

Say What? ;-)

If you lose either TX or RX, then you don't have two-way communications.
Therefore you have two-way radio communications failure and should operate
according to 91.185.

If you lose just transmitter or just receiver you can still communicate
one-way. Two-way radio communications failure means loss of both
transmitter and receiver.

That's ridiculous.

Yes, you could also use smoke signals, rock your wings, etc. - However,
if you think that losing your transmitter during an IFR flight is not
considered a "two way radio communications failure" as used in 91.185
you're fooling yourself.

In my case, it was, "N17AV, if you read this transmission, turn left 30
degrees and ident", which was soon followed by, "Radar contact, continue
along previously cleared route". Or words to that effect.

Our route was POU V157 HAARP HPN. Once you get to the bend in V157, you're
very close to the ILS-16 localizer. We decided to just go for the
localizer as soon as we got there. The moment we left the airway, we
heard, "N17AV, you appear to be flying the ILS-16, cleared approach".

We flew the approach. We didn't see any light signals from the tower, nor
did we waste any effort looking for them. We landed, and taxied off the
runway. Our handheld VHF, which didn't work for **** in the air, was able
to talk to ground. We taxied back to the ramp with them and that was the
end of that.

If you lose either TX or RX, then you don't have two-way communications.
Therefore you have two-way radio communications failure and should
operate
according to 91.185.


If you lose just transmitter or just receiver you can still communicate
one-way. Two-way radio communications failure means loss of both
transmitter and receiver.

This argument reminds me of the debate of which is the inner or outer knob
on our GPSs.
