RCAF Detachment Granum

The airfield was closed following the end of World War II and the subsequent termination of the British Commonwealth Air Training Plan (BCATP). As a relief landing field, its purpose became obsolete once the training program at its parent station, No. 7 Service Flying Training School (SFTS) at RCAF Station Fort Macleod, ceased operations.

The site is now private agricultural land. The original triangular runway layout is still clearly visible from satellite imagery, but the surfaces have long since been returned to nature and are used for farming, likely for growing hay or for cattle grazing. Several modern farm buildings and grain silos have been constructed on the property, adjacent to the original airfield footprint. The runways themselves are not paved and are impassable for aircraft.

RCAF Detachment Granum was constructed during World War II as a Relief Landing Field (R1) for No. 7 Service Flying Training School (SFTS), based at nearby RCAF Station Fort Macleod. It was a crucial component of the British Commonwealth Air Training Plan (BCATP), one of the single largest aviation training programs in history. The airfield's primary function was to handle overflow air traffic from the main base, allowing student pilots to practice essential skills like takeoffs, landings, and emergency procedures in a less congested environment. Pilots at No. 7 SFTS primarily trained on the Avro Anson multi-engine aircraft. The airfield featured the standard triangular runway pattern common to BCATP fields to allow for safe operations regardless of wind direction.

There are no known plans or prospects for reopening RCAF Detachment Granum as an airport. The land is privately owned and has been fully integrated into agricultural use for over 75 years. There is no economic or logistical demand that would justify the significant investment required to restore the site to aviation standards.
