fly by the seat of your pants
Meaning
To do something using instinct and improvisation, without a plan or exact information.
Origin
From early aviation: pilots without instruments sometimes judged the plane’s attitude and movement by bodily sensations felt through the seat of their pants, so it came to mean relying on instinct rather than data or planning.
Notes
Informal and common. Can sound admiring (resourceful) or critical (unprepared/risky) depending on context.
