Key Takeaways:

A "Brasher warning" is an immediate notification from air traffic control to a pilot regarding a "possible pilot deviation," such as an altitude error.
The warning is named after Captain Jack Brasher, whose alleged 1985 deviation was not communicated immediately, making it impossible for him to recall details months later.
This procedure was developed to ensure pilots are informed of potential deviations at the time they occur, facilitating recall for investigation, learning, and ultimately enhancing aviation safety.

Question: One of the old guys at the FBO was talking about getting his first Brasher warning in 30 years of professional flying for a possible violation. Is “brashing” pilot slang for something?

Answer: The pilot in question may have made a pilot deviation—like being at the wrong altitude—and was warned by air traffic control: “We have a number for you to copy, possible pilot deviation.”
