the AAC doesn't have co-pilots. Either a pilot or Commander (a more aggressive version of aircraft Captain). He was an aircraft Captain the first time he went solo, as we all were, so will do his time before getting command regardless of airframe.
Thanks for that, wasn't at all sure how it went these days. I came through in 1964/5 (!) in the days of the 'Integrated Flights' when one was posted back to the Air Troop of one's regiment/corps or posted to an AAC flight/Squadron that needed pilots. All rather different now
