Page "British Commonwealth Air Training Plan" Paragraph 9

Article XV of the agreement stipulated that graduates belonging to Dominion air forces, where they were assigned to service with the RAF, should be placed in new squadrons identified with the RAAF, RCAF and RNZAF.

These units later became known as " Article XV squadrons ".

Articles XVI and XVII stipulated that the UK government would be wholly responsible for the pay and entitlements of graduates, once they were placed with RAF or Article XV units.

Some pre-war / regular RAAF and RCAF squadrons also served under RAF operational control, while New Zealand and Rhodesian personnel were frequently assigned to RAF squadrons with the honorifics of " and "" in their names.

However, in practice — and technically in contravention of Article XV — most personnel from other Commonwealth countries, while they were under RAF operational control, were assigned to British units.
