What does SLOT mean in the aviation field?

Answer 1

If you're talking about formation flying, the slot position is the position below and aft of the leader and the two wing men, on the centerline of the lead aircraft. This is sometimes referred to as the #4 position.

Alternate AnswerSLOT - A long, narrow, spanwise gap in a wing, usually near the leading edge, to improve airflow at high angles of attack for slower landing speeds.

SLOTTED FLAP - A flap that, when depressed, exposes a slot and increases airflow between itself and the rear edge of the wing.

Crew Slot - I think this term is used to refer to a Flight Schedule for a crew member. Term is similar to a job position.
