KC-135R Stratotanker

Block 25

The Reduced Vertical Separation Minimum (RVSM) equipment is being installed on eight (8) Receptacle Configured KC-135R aircraft (Pacer CRAG Block 25 configuration). This is a continuation of RVSM Flight Test Validation acquired by OC-ALC/LC from the KC-135 OEM. This effort includes integration and installation of government furnished KC-135R RVSM kits into eight KC-135R Air Refueling Receptacle equipped aircraft.

In an effort to deal with the tremendous growth of air traffic, International Civil Aviation Organization member nations have agreed to comply with RVSM as one of many planned air traffic management changes. RVSM reduces the vertical separation between aircraft from 2,000 to 1,000 feet at altitudes between 33,000 and 37,000 feet. Eventually, the RVSM airspace will be expanded to include altitudes between 29,000 and 41,000 feet. While the North Atlantic is the first region to initiate RVSM, it is expected to eventually be implemented over the Pacific ocean, continental U.S., and European airspace as well. These RVSM requirements represent one of the most significant changes in oceanic air traffic management in the last 40 years.

The RVSM kit consists of Group B components and Group A hardware including wiring harnesses, pitot static tubing and metal fabricated parts. Due to receptacle type variations, modifications required to the GFP RVSM kits will vary from aircraft to aircraft. Due to the high utilization of these aircraft, minimum aircraft down time and flexible scheduling of modification dates are necessary to meet a critical operational requirement. Aircraft No. 1 is scheduled for modification on/or about Jan 01 with final aircraft completion no later than Dec 03 (aircraft will be modified in a serial fashion with some gap in activity between each aircraft).
