INSTRUCTIONAL REGISTER

Economic pressures in the mid 1930's made it necessary to declare only active equipment on strength but still there was a need to maintain suitable records of aircraft assigned to the role of training aids. The solution was found in the opening of an instructional register for aircraft no longer fit for active flying but useful as ground instructional aids. On14 February, 1935, the instructional register was opened with an "A" prefix followed by simple numerals in order. Thus DH Moth RCAF 56 became Al and succeeding transfers to this register were made in numerical order. One degree of specification later applied to this register was the use of "A" to indicate an airframe where engine running could be practised. The suffix "B" (eg 250B) was used where the airframe was suitable for stripping and a suffix "C" was used to indicate sectioned aircraft to be used solely as visual aids. The instructional register presented in this book does not identify these variations because in the life of an instructional airframe it was frequently transferred from one state to another and on occasion restored to its original "A" state.
