FCC radio permit stupid question
Alright here's what I guess will be a stupid question because I guess I should know the answer to this.
I always thought that a Radio Permit was no longer needed on board the aircraft or even needed to be applied for and received. However, we just bought our first "step up" aircraft being a King Air with an HF radio, and displayed next to the Registration is the previous owners Radio Operators Permit.
Do I/We need a Radio Permit with this aircraft?
