What is the role of "NORDO" in radiotelephone terminology?

Explanation:
NORDO signals no radio capability. In radiotelephony, this tag is used to indicate that the aircraft cannot transmit or receive voice communications, so two-way contact with air traffic control (and others) isn’t possible. That’s why this status matters for safety— pilots must rely on alternate procedures and signals and ATC must plan accordingly. It isn’t about being on hold, the controller being unavailable, or whether the flight is instrument-rated; those are different situations.
