Definition
A radio procedure word used at the end of a transmission to indicate that the speaker has finished talking and expects a response from the receiving station.
Plain English
It means "I'm done talking — your turn to reply."
Context Anchor
Used in radio calls when pilots, controllers, or other stations need to make clear that a reply is expected.
Derivation
Over comes from an old English word meaning “above,” “across,” or “beyond.” In radio use, it came to mark that one speaker’s turn has passed over to the other person.
Why Pilots Care
Prevents simultaneous transmissions and keeps two-way radio exchanges orderly on shared frequencies.
Intuition Check
OVER does not mean the aircraft is physically over a place here. In radio phraseology, it means the speaker has finished for the moment and is handing the conversation to the other station.
