For example, I've twice been cleared to random 5-letter fixes which

specified. Actually, both approaches ended up being visuals. I
don't know every 5 character permutation of "wip-pee" intersection
and which one applies - running through the guesses takes some
serious knob time.

Hah! I hear ya. Try finding TIFTO on your GPS in south Georgia.
