REQUIREMENT RATIONALE (A.3.2.10)
The components of the EPS are normally dispersed throughout the aircraft and are subjected to a wide variety of environments. Therefore, environmental requirements have to be
determined for each component individually.
REQUIREMENT GUIDANCE (A.3.2.10)
The intent of this requirement is to provide a suitable definition of environmental conditions under which the ------------ must operate periodically and continuously. Environmental requirements are usually included in the host aircraft specifications. However, changes in the air vehicle since its initial configuration have to be considered. With the environment defined, the various tests needed during the development cycle can be tailored to meet the application. The risk is the ability to accurately assess the true environment.
MIL-STD-810 requirements can be specified for various environmental tests if it is determined that they are applicable to the particular weapon system. It is generally accepted that the performance of various equipment is degraded at environmental extremes such as high and low temperature. It will be necessary to determine the weapons systems performance requirements at these extremes and specify the performance of the equipment accordingly.
Use care to avoid unnecessary requirements or requirements the equipment is not susceptible, such as noise on heavy equipment or solar radiation on equipment in bays.
