T.O. GR1F16CJ1 826Change 1 When close interval stream operations are being conducted, do not use orbit delays to control timing. The RZ will be located a minimum of 50 NM prior to the ARIP/SD. Tracks from the ARIP/SD may be established from any direction and need not necessarily be an extension of the air refueling track. If orbit delays are required, they will be accomplished by orbiting at the RZ point along an extension of the track from the RZ to the ARIP/SD. Orbit in a racetrack pattern using 30 degree banked turns and a maximum of 15 NM straight legs (unless operational directives specify longer straight legs). Tanker(s) and receiver(s) will joinup at the RZ by controlling timing so they arrive at the RZ at the same time. Timing to the RZ may be adjusted using differential airspeeds, orbit delays or timing triangles. If a planned orbit delay is used, receiver(s) and tanker(s) may accomplish joinup in the orbit. Assigned altitudes at the RZ will provide at least 1000 feet separation between affected airplanes (highest tanker and lowest receiver), with the receivers normally at the highest altitude. If the receiver(s) planned level off altitude is within 30 minutes flying time from the ARIP, the receiver(s) may level off below the tanker and maintain an altitude which provides a minimum of 1000 feet vertical separation between the highest receiver(s) and the lowest tanker(s). Communications will be in accordance with specified emission option. If radio contact between the airplanes has not been established prior to the rendezvous control time, or the adjusted rendezvous control time, airplanes will maintain altitude and depart the RZ to cross the ARCP at the ARCT. Delays at the ARCP will use normal orbit procedures unless otherwise directed. If there is minimal separation between following aircraft or cells using the same track, orbits at the ARCP will require close coordination and a thorough crew briefing to ensure altitude separation. When the aircraft or cells pass the ARIP/SD, the tanker(s) and receiver(s) will echelon and the receiver(s) will begin descent to the base air refueling altitude. Receiver(s) will descend to be at the base altitude 80 NM prior to the ARCP. Tanker(s) will maintain published buddy cruise KCAS and adjust to air refueling airspeed crossing the ARCP. NOTE For peacetime training missions, the ARIP or the ARCP may be designated as the RZ. In these cases, cells will echelon and start descent at the base refueling altitude as soon as practical after rendezvous completion. If prebriefed, tanker(s) and receiver(s) may adjust to air refueling airspeed and begin air refueling after passing the RZ. Once departing the RZ/ARIP, the tanker(s) should fly centerline. The receiver is the maneuvering aircraft. If the tanker is behind the receiver, the tanker should accelerate and pass slightly off the left wing of the receiver. Alternate Rendezvous Procedures Tanker and receiver crews must be prepared at all times to accomplish the rendezvous using whatever resources are available. When rendezvous equipment is degraded, tankers and receivers will fly the same profiles as described in previous paragraphs. The following are some suggested alternate rendezvous procedures which should be used in any combination to ensure a successful rendezvous: NOTE Initial visual contact between the receiver and tanker may be enhanced, inflight weather conditions permitting, if the tanker jettisons fuel to increase its visual signature. This procedure may be initiated/requested by the tanker, re ceiver, or the ground agency controlling the rendezvous. It should only be used if a receiver low fuel state or other similar circumstances require the rendezvous be expedited. If required, the tanker will dump fuel in 500 1000 pound incre ments until positive visual contact can be maintained. D Radar/Rendezvous Beacons. The receiver/tanker beacons may be used for range and offset information with suitably equipped airplanes. Depending on equipment capability, one airplane should maintain the planned outbound or inbound track while the other airplane maneuvers to establish the planned offset. The tanker will clearly establish which airplane will be maneuvering. |
