capt. Captain.
captain 1 Very loosely, any PIC.
2 More correctly, officer in charge of military, naval or
commercial aircraft having flight crew numbering more
than one; not normally used with two-seat combat
aircraft. Usually * is PIC but in RAF in WW2 could have
any aircrew trade, in today’s MR [e.g. Nimrod] * is Tac
Nav, and in AAC helo * is Gunner [missile operator]
regardless of rank. Airline * has status of rank with four
gold stripes.
captain’s bars Parallel lights under tanker fuselage to
assist receiver’s station-keeping (USAF).
captain’s discretion Undefinable. Most airline captains
are permitted to ignore some rules, such as number of
hours on duty, or limitations on flight time.

capture 1 In flying aircraft or space vehicle, to control
trajectory to acquire and hold given instrument reading.
2 In flying aircraft, to control trajectory to intercept
and then follow external radio beam (eg ILS, radio range).
