RCAF Station Centralia was a Royal Canadian Air Force training base located just outside the village of Centralia near Exeter, Ontario, Canada. It became one of the largest training stations in Canada. It was turned over to civilian use after 1967, and currently operates as the Centralia/James T. Field Memorial Aerodrome. Flying schools were established across Canada as part of the British Commonwealth Air Training Plan during World War II. Centralia was the location for No. 9 Service Flying Training School (SFTS). Service Flying Training Schools provided advanced training to pilots who had graduated from Elementary Flying Training Schools (EFTSs). Trainee pilots flew the Avro Anson and North American Harvard. No. 9 SFTS had moved to Centralia from RCAF Station Summerside, Prince Edward Island, in July 1942. Relief landing fields for Centralia were located at Grand Bend and St. Joseph. No. 9 SFTS ceased operation in June 1945 and was replaced by No. 1 Aircrew Conditioning Unit (ACU). ACUs trained service personnel for operations in the war's Pacific theatre. When No. 1 ACU was closed after the war, the RCAF formed No. 1 Flying Training School (No. 1 FTS) which used Ansons and Harvards. The first and last flying course was in January 1946. The course lasted for three weeks before it was cancelled. In approximately 1942 the aerodrome was listed as RCAF Aerodrome - Centralia, Ontario at with a variation of 5 degrees west and elevation of . The aerodrome was listed as "Under construction" with three runways as follows: Because of increasing tensions between the Soviet Bloc and the West, defence expenditures were increased and the Canadian forces were strengthened. Centralia, along with a number of other stations, underwent major rehabilitation to better accommodate aircrew training. Centralia was reactivated in January 1947 to provide accommodation and training facilities for No. 1 Radar and Communications School (No. 1 R&CS) that was based in nearby RCAF Station Clinton. No.
