Airborne, Inhabited,
Cargo AIC
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 as the
T38.
Airborne, Inhabited,
Fighter AIF
Same as AIC but installed
on high performance aircraft such as fighters and interceptors.
Examples
include the F15, F16, F111, F/A18 and A10 aircraft.
Airborne, Uninhabited,
Cargo, AUC
Environmentally
uncontrolled areas, which cannot be inhabited by an aircraft, crew
during
flight. Environmental extremes of pressure, temperature and shock may
be
severe. Examples include uninhabited areas pf long mission aircraft
such as the
C130, C5, B52 and C141. This category also applies to uninhabited areas
pf lower
performance smaller aircraft such as the T38.
Airborne, Uninhabited,
Fighter, AUF
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,
ARW
Equipment installed on
helicopters. Applies to both internally and externally mounted
equipment such
as laser designators, fire control systems, and communications
equipment.
Space, Flight, SF
Earth orbital. Approaches
benign ground conditions. Vehicles neither under powered flight nor in
atmospheric reentry; include satellites and shuttles.
Missile, Flight, MF
Conditions related to
powered flight or air breathing missiles, cruise missiles, and missiles
in
unpowered free flight.
Missile, Launch, ML
Severe conditions related
to missile launch (air, ground, and sea), space vehicle boost into
orbit, and
vehicle re-entry and landing by parachute. Also applies to solid rocket
motor
propulsion powered flight, and torpedo and missile launch from
submarines.
