Definition
A radiotelephony term used to indicate that a transmission has been received and understood. It does not mean 'yes' and does not constitute agreement, compliance, or an answer to a question.
Plain English
It means 'I heard you and I understand what you said.' It does not mean 'yes' or 'I will do it.'
Context Anchor
Used in pilot-controller radio communication when one person needs to acknowledge that a message was received.
Derivation
Comes from the older phonetic alphabet where the letter 'R' was spoken as 'Roger.' 'R' stood for 'Received.' The newer ICAO alphabet uses 'Romeo' for the letter R, but 'Roger' survived as the word for 'message received.'
Why Pilots Care
It confirms that critical instructions or information have been received, reducing the need for repeats and helping prevent miscommunication during flight.
Intuition Check
Do not treat Roger as “yes” or “permission granted.” Roger only means the last transmission was received.
Example Sentence 1
After the controller advised 'Cessna 4-2-Charlie, traffic at two o'clock, three miles, opposite direction,' the pilot replied, 'Roger, looking.'
Example Sentence 2
The controller acknowledged the pilot's readback with 'Roger' before issuing the next instruction.
