The Project’s Mission Profile file stores one or more profile definitions. Each profile definition has its own mission time and defines the environments and temperatures experienced in different phases of the mission. The data in a profile definition is used to calculate mission failure rate, MTBF (mean time between failures), availability, and reliability. If you select a reliability prediction calculation model that does not use mission profiles, this file is ignored. If different failure effects are designated for different mission phases, the FMEA module also uses the profile definitions in this file. The following table describes the two panes in the Mission Profile file.
