These recommendations apply to the user's manual for any computer program pertaining to aircraft ECS. This includes computer programs for:

a. Cabin air conditioning and pressurization performance.

These recommendations apply to user's manuals for generalized computer programs as well as those for a specific component or system.

The user's manual is a document which defines all procedures necessary for a user to initiate and utilize the program and obtain output data. The user's manual does not normally contain procedures or information required solely for modifying the program. Such procedures or information are contained in a programming or operator's manual; however, they may be contained in supplemental documentation to the user's manual.

These recommendations apply to computer programs which will be voluntarily released to users or are required to be released by contract. It is the intent of this recommend practice that proprietary data not be included in the user's manual.
