Use Environment per MIL HDBK-217F (Airborne):
Airborne, inhabited, Cargo: Typical conditions in cargo compartments which can be occupied by an aircrew. Environment extremes of pressure, temperature, shock and vibration are minimal. Examples include long mission aircraft such as the C130, C5,B52, and C141. This category also applies to inhabited areas in lower performance smaller aircraft such as the T38.
Airborne, Inhabited, Fighter: Same as AIC but installed on high performance aircraft such as fighters and interceptors. Examples include the F15, F61, F111 , FIA 18 and A10 aircraft.
Airborne, Uninhabited, Cargo: Environmentally uncontrolled areas which cannot be inhabited by an aircrew during flight. Environmental extremes,of pressure, temperature and shock may be severe. Examples include uninhabited areas of long mission aircraft such as the C130, C5A , B52 and C141, This category also applies to uninhabited area of lower performance smaller aircraft such as the T38.
Airborne, Uninhabited, Fighter: Same as AUC but installed on high performance aircraft such as fighters and interceptors. Examples include the F15, F16, F111 and A10 aircraft.
Airborne, Rotary Winged: Equipment installed on helicopters. Applies to both internally and externally mounted equipment such as laser designators, fire control systems, and communications equipment.
Air Portable: Denotes materiel that is suitable for transport by an aircraft loaded internally or externally, with no more than minor dismantling and reassembling within the capabilities of user units.

Mean Time Between Failure Definition .... Military Specifications
For reference; MIL-E-5400: Warmup time shall be such as to provide the specified performance within a period as specified by the detail equipment specification.Unless other wise specified,the warmup time at temperatures down to -54C shall not exceed 2 minutes for equipment essential to flight safety, and shall not exceed 5 minutes for equipment not essential to flight safety.
