Squadron Organisation This excerpt on Australian Spitfire pilot training is taken from Australian War Memorial Records AWM173 7/4 Part 2 ‘Narrative of RAAF in Single Engined Squadrons of Fighter Command.’ In single engine fighter squadrons (Spitfire and Hurricane) the normal compliment of operational aircraft is sixteen held on initial issue and at least two or three aircraft held on immediate reserve. These aircraft are manned by about 25 pilots who are divided into two flights, A and B of approximately equal strength. The ground crew are similarly divided and service the aircraft allotted to their particular flight. In actual practice it is usual for each ground crew to have one particular aircraft as their charge. Each of the flights is commanded by a pilot of the rank of Flight Lieutenant and the Squadron is commanded by a pilot of the rank Squadron Leader.
