If you've still got a radar target you can still separate from a NORDO
aircraft. If you've got no radar then everything beneath the NORDO is
effectively shut down until it's known to be on the ground.

If you are NORDO, your mode C might not work either... How would ATC
know who's below it?

Whoa there, big hearted fellow. If you're now gonna say the comm failure
might spread to your transponder and encoder leaving you nonradar as well as
NORDO, then I'm gonna say it can spread to your nav radios as well, leaving
you unable to hold anywhere. All the more reason to put it on the ground as
soon as possible.

All the more reason to have a handheld comm, a handheld GPS (turned on using
ship's power for the whole flight so you don't have to wait for it to find
itself), and plenty of fresh batteries.

If you have a handheld comm you're not NORDO.

You may as well be if the handheld doesn't have the power to reach ATC.

You are supposed to be flying at your planned altitude. I don't know
how far ATC would be willing to trust that, though -- you'd certainly
be within your rights to choose a different altitude to avoid
turbulence or icing.

How good a job can primary surveillance radar do on picking out a
target's altitude? Obviously, SSR won't help.


All the best,

Where are those rights found?

It can't do that job at all.

Emergency authority of the pilot (sorry, I left out the adjective
"severe" before "turbulence"). If I'm flying in IMC and go NORDO,
then hit icing or severe turbulence, I'm not going to worry about
sticking with my flight-plan altitude.

I don't claim that it would be OK for the pilot to change altitude
just to avoid light or moderate chop.


All the best,


David
