Scope
This ARP discusses design philosophy, system and equipment requirements, environmental conditions, and design considerations for helicopter environmental control systems (ECS). The helicopter ECS comprises that arrangement of equipment, controls, and indicators which supply and distribute dehumidified conditioned air for ventilation, cooling and heating of the occupied compartments, and cooling of the avionics. The principal features of the system are:
-
a
A controlled fresh air supply
-
b
A means for cooling (air or vapor cycle units and heat exchangers)
-
c
A means for removing excess moisture from the air supply
-
d
A means for heating
-
e
A temperature control system
-
f
A conditioned air distribution system
The ARP is applicable to both civil and military helicopters where an ECS is specified; however, certain requirements peculiar to military applications, such as nuclear, biological and chemical (NBC) protection, are not covered. The integration of NBC protection into aircraft ECS is discussed in AIR4362.
Rationale
ARP292C has been reaffirmed to comply with the SAE five-year review policy.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
