Pre-takeoff checklist
"The FAA and FCC want aviators to remember that a specific radio frequency is for emergencies, and that's it. The FCC made clear in a notice Tuesday that the frequency isn't for "false distress or emergency messages, superfluous communications, messages containing obscene, indecent or profane words or meaning, general calls (calls not addressed to a particular station), routine messages, radio tests and transmission of recorded audio (such as music or spoken text)." The FAA said that each one of those kinds of chatter has been "happening quite often" on the frequency meant for real distress situations."
