When a new South African set of decorations and medals was instituted on 6 April 1952, to replace most of the British awards which had been used to date, South African equivalents of, amongst others, the British
Distinguished Flying Cross (DFC) and
Air Force Cross (AFC), were omitted. This omission was only belatedly addressed near the end of the 1966-1989 Border War, when the institution of the Air Force Cross (CA) was proposed. As proposed, the decoration was intended for award only to air crew, who displayed exceptional courage and leadership during dangerous or critical situations while airborne, where an award for bravery was not suitable, based on the premise that bravery involves knowingly entering mortal danger from a position of relative safety, as opposed to skillfully reacting to an unforeseen situation of mortal danger. The proposed criteria were described in the draft warrant as excellent airmanship or outstanding ingenuity or skill during emergencies or unusual situations in the air. • One incident which eventually led to the proposed decoration, was an in-flight malfunction in a
Canberra B(1) Mk. 12 which disabled the aircraft's control column. In spite of advice from the ground to ditch the aircraft, since the pilot would be unlikely to be able to land it safely, he managed to land it at
Air Force Base Waterkloof with minimal damage, while having only trim, rudder and engine power adjustments as controls. • Another example was a
Dakota C-47, which lost its rudder and elevators when struck by a surface-to-air missile, whose commander managed to land safely at
Air Force Base Grootfontein by having his passengers, most of them serving General and Flag Officers, move forward and backward in the cabin, as required, to alter the aircraft's centre of gravity. When the other three Arms of the Service subsequently proposed that an
Army Cross (CM), a
Navy Cross (CN) and a
Medical Service Cross (CC) should be instituted simultaneously, the proposed award criteria of all four crosses were amended to outstanding ingenuity or skill in the utilisation and control of personnel, weaponry or other equipment in dangerous situations and, in the case of the Air Force Cross, not necessarily restricted to flying. ==Institution==
