Oswego, NY: IBM Federal Systems Division, Space Guidance Center, 1962. Presumed First Edition, First printing. Wraps. Good. Format is approximately 8 inches by 10.5 inches. Unpaginated (12 pages plus covers). Stated inside the front cover "Not for Public Dissemination". Illustrations. Recommended Reading. Cover has wear and soiling. Computer, Altitude Vertical Velocity, AN/ASQ-38 (For B-52E And Later). The aircraft's new ASQ-38 bombing-navigation system at first was difficult to maintain. Engineering changes were initiated to improve low-level terrain avoidance for the long term. A special project, Jolly Well, exchanged major parts of the ASQ-38 and replaced the terrain computer-another critical component of the overall system. Jolly Well was completed in 1964, after successful modification of the ASQ-38 of 480 B-52s-B-52E, F, G, and H models. ACR is believed to stand for Advanced Capabilities Radar. T A Techniques is believed to stand for Terrain Approach Techniques. This document was intended for use by Strategic Air Command crews. A major element in accomplishing a successful TA flight is the rapid and correct interpretations of the data presented on the pilot's indictor. this issue of the Operations Bulletin is concerned with scope interpretation and TA techniques. The information presented is based on the experience of the flight test crews of the Air Force, the Boeing Company, and IBM and confirmed by SAC crews.

The Boeing B-52 Stratofortress is an American long-range, subsonic, jet-powered strategic bomber. The B-52 was designed and built by Boeing, which has continued to provide support and upgrades. It has been operated by the United States Air Force (USAF) since the 1950s. The bomber is capable of carrying up to 70,000 pounds (32,000 kg) of weapons, and has a typical combat range of more than 8,800 miles (14,080 km) without aerial refueling.

Beginning with the successful contract bid in June 1946, the B-52 design evolved from a straight wing aircraft powered by six turboprop engines to the final prototype YB-52 with eight turbojet engines and swept wings. The B-52 took its maiden flight in April 1952. Built to carry nuclear weapons for Cold War-era deterrence missions, the B-52 Stratofortress replaced the Convair B-36. A veteran of several wars, the B-52 has dropped only conventional munitions in combat. The B-52's official name Stratofortress is rarely used; informally, the aircraft has become commonly referred to as the BUFF (Big Ugly Fat Fella).
