Intercepting aircraft approach intercepted aircraft from astern. Element leader reduces throttle and extends dive brakes. Wingman continues to the opposite side of the intercepted aircraft from the leader and climbs to 4,000 feet above target aircraft altitude for the purpose of maintaining surveillance, using economical power setting. Should weather ceiling not permit surveillance from this position, wingman will assume a position on either side of aircraft which will permit observation of both the aircraft and his element leader at a distance of 3,000 feet from the intercepted aircraft, if visibility permits. During surveillance, wingman will maintain position by S-turns rather than reducing speed with dive brakes. The desired position of the element leader is 1,000 feet abreast the aircraft at the aircraft's altitude. After speed and position are stabilized, element proceeds with Phase II of the procedure.
1-6-2. PHASE II
Wingman continues surveillance. Element leader begins gentle closure of aircraft at same level until no closer than absolutely necessary to obtain information needed. As he gives identification information to director, wingman copies information for mission report. Element leader uses every precaution to avoid startling intercepted aircrew or passengers, keeping constantly in mind that maneuvers considered normal to a fighter aircraft may be considered hazardous to passengers and crews of nonfighter aircraft. Upon completion of identification, fighter-interceptors withdraw from aircraft's vicinity as outlined in Phase III.
1-6-3. PHASE III
Element leader breaks gently away from aircraft in shallow dive to pick up speed. Wingman stays well clear of intercepted aircraft and joins leader.
