No. 15 (Pilot) Advanced Flying Unit was a Royal Air Force training formation formed during World War II to provide intermediate and advanced pilot instruction. It operated under the auspices of Flying Training Command and coordinated conversion training between elementary schools such as No. 1 Elementary Flying Training School and operational units like Fighter Command and Bomber Command. The unit contributed to aircrew preparation for campaigns including the North African Campaign, the Italian Campaign, and the Western Front (World War II).
Formed in 1942 amid the expansion of the British Commonwealth Air Training Plan and the reorganisation of RAF Training Command, the unit emerged as part of wider efforts exemplified by formations like No. 1 Group RAF and institutions such as the Aeroplane and Armament Experimental Establishment. It reflected doctrines developed after lessons from the Battle of Britain, the Blitz, and the Battle of the Atlantic, aligning with policy debates involving figures such as Arthur Harris and Charles Portal. Throughout 1943–1944 the unit adjusted syllabus and strength in response to operational needs signalled by operations like Operation Torch and Operation Overlord, before winding down activities as aircrew throughput declined after VE Day.
The unit's remit encompassed advanced pilot conversion, instrument flying, night navigation, formation tactics, and gunnery preparation to feed aircrew into commands including Transport Command, Coastal Command, Bomber Command, and Fighter Command. Training incorporated procedures and standards set by establishments such as the Royal Air Force College Cranwell and instructional methods influenced by aviators like Arthur Tedder and instructors seconded from squadrons such as No. 617 Squadron RAF and No. 303 Squadron RAF. Cadets progressed from elementary schools such as No. 2 Elementary Flying Training School through advanced units and underwent exercises resembling sorties flown in theatres referenced by Mediterranean Air Command and Allied Expeditionary Air Force planners.
The unit operated a mix of single‑ and twin‑engine types for conversion and advanced handling. Typical types included the Avro Anson for navigation and multi‑engine drills, the Airspeed Oxford for instrument and night training, the Miles Master for advanced handling and aerobatics, and the Hawker Hurricane for fighter conversion. Other types seen in associated training pools and relief landing grounds comprised the de Havilland Tiger Moth for refresher tasks, the Supermarine Spitfire for high‑performance familiarisation, and the Fairey Battle in some early multi‑crew exercises. The unit also liaised with maintenance depots like No. 43 Maintenance Unit RAF and testing establishments including the Royal Aircraft Establishment.
Initially based at satellite airfields that were part of the RAF training network such as RAF Cranage, the unit operated relief landing grounds near RAF Church Lawford and detachments at stations like RAF Tern Hill and RAF Wellesbourne Mountford. Movements reflected strategic dispersal policies seen across fields such as RAF Halton and RAF Shawbury to mitigate risks from Luftwaffe raids during the Blitz. During 1943–1945 the unit rotated through airfields administered by groups including No. 21 Group RAF and utilised ranges overseen by organisations such as the Air Ministry Experimental Flight for instrument and gunnery practice.
Organisationally the unit reported to higher echelon training commands analogous to No. 21 Group RAF and followed doctrine promulgated by the Air Ministry and overseen by chiefs like Charles Portal. Its internal structure featured an HQ flight, multiple conversion flights, an instrument and navigation flight, and an armament flight coordinating with depot units such as No. 6 Repair and Salvage Unit RAF. Commanding officers were drawn from experienced squadron leaders and wing commanders who previously served with operational units like No. 303 Squadron RAF and staff colleges such as the RAF Staff College, Bracknell.
Instructors and alumni included decorated aircrew who had served in campaigns like the Battle of Britain and the North African Campaign, some later posting to squadrons such as No. 617 Squadron RAF and No. 1 Squadron RAF. The unit experienced incidents typical of wartime training: forced landings recorded near RAF Northolt and occasional accidents investigated by boards referencing procedures at the Aeronautical Inspection Directorate. Distinguished visitors and inspection tours involved figures from Ministry of Aircraft Production and senior officers like Keith Park. Postwar demobilisation saw many instructors return to units such as Transport Command or to civilian roles at organisations including British European Airways and universities like University of Cambridge where aviation research continued.
