The aircraft and its systems
The FB-111A is a two-place (side-by-side) long range fighter bomber. The wing, equipped with leading edge slats and trailing edge flaps, maybe be varied in sweep, area, camber and aspect ratio. This capability earned it the distinction of being the world's first variable geometry production aircraft. The crew escape system is an airtight module which may be severed from the airframe by different methods. The module, once jettisoned, provides all life support and survival systems for the aircrew. These include protection from wind blast during ejection, oxygen, survival equipment, radio beacon and water flotation. In fact ejection can be initiated when the aircraft is completely submerged. Power is provided by two Pratt and Whitney TF-30 avial-flow dual compressor turbofan engines. Both engines are equipped with afterburner and develop around 20,000 pounds of thrust apiece. The aircraft design and engine thrust enable operations above 60,000 feet exceeding speeds of mach 2.5. The terrain following radar is unique in its ability to fly the aircraft over obstacles as low as 200 feet, at speeds of mach 1.1. This combined with an advanced forward looking radar, allows navigation, location, and penetration of enemy targets with extreme accuracy.
Note: The information presented on this page were taken from an "OJT Instructor Guide". This handbook was developed by the 436th Strategic Training Squadron / OL-PL for FB-111A maintainers. It was conceived as a training aid and had the advantage of having a lot of general infos in one book. Its only purpose was to give quick reference, as far as systems, operations, functions, etc... The pressures, readings and limitations were subject to change, and were used only to provide general parameters.
