I thought you had to get an expect further clearance time as part of the
hold instructions in case your radio failed shortly after directed to
hold? Otherwise, how would you know how many turns to make in holding
before proceeding on course? I'm not arguing, just asking,


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

I've had several lost-comms. I seem to remember:

1) Fried xmit relay in the audio panel

2) Defective headset jacks

3) Broken wire in my headset cable

None of these affected the nav radios.
