This handbook was developed by the 436th STS/OL-PL for FB-111A maintainers. As a training aid it had the advantage of having a lot of general information, you may need, in one book. Its only purpose was to give you a quick reference, as far as systems, operations, functions, etc... The pressures, readings and limitations are subject to change, and are used only to provide general parameters. Use it whenever it can be helpful to you, and mark it to meet your own particular needs. This handbook is not tach data and will not be used as such. Nor can it be used as a reference for accomplishing a task. If you use it for the purpose of becoming more familiar with the aircraft and systems, it will have served its purpose. Notes: Sections 2,3,4 and 12 are covered on different pages, click on the link to view it.
