Without an EFC I wouldn't enter the hold. It's a moot point anyway,
whatever caused my comm radios to go belly up will affect my nav radios the
same way and I won't be able to identify the holding fix.

Not true. Stuck mic comes to mind quickly. Squelch set too high would be
second in mind. Something could fry within the com unit....

NAV still works, and before radios went south, at least the EFC would allow
me to navigate predictably. Again, realizing remotely possible, the rules
and regs did build this in with the EFC feature.
