AFGS�87219B APPENDIX A
d. Compliance with the design requirements for external power receptacles and their installation shall be determined by inspection.
e. Compliance with other external ground power requirements shall be as follows:
------------.
VERIFICATION RATIONALE (A.4.2.S)
Analyses of external power requirements are necessary in order to design the EPS interface with external power. Subsequent testing is required to confirm that the external power performance requirements are met. The proper selection and installation of external power receptacles can be verified by inspection.
VERIFICATION GUIDANCE (A.4.2.S)
a. Use the procedures of MIL-E-7016 to analyze the requirements for external power. b. Proper selection and installation of external power receptacles can be verified by
inspection of the applicable drawings and/or by inspection of the aircraft.
c. Performance requirements of the EPS with respect to external power can be verified by mockup tests and aircraft tests.
VERIFICATION LESSONS LEARNED (A.4.2.S)
External power receptacles have been standardized to assure that any aircraft can be provided external power at any location. This eliminates the need for onboard APUs, etc. If the standard power receptacle is not used, then special power carts or adapters will be required at remote locations.
A.3.2.6 Auxiliary power.
The EPS shall be capable of generating, controlling, and distributing power from on-board auxiliary power units for ground or airborne operations as follows: ------------.
REQUIREMENT RATIONALE (A.3.2.6)
Aircraft operational requirements may necessitate an on-board auxiliary power unit (APU) to provide electric power for certain modes of ground or air operation. The EPS must be capable of generating, controlling, and distributing APU electric power in a safe and effective manner. Considerations include the quantity of APU power required, whether both ground and airborne operation are required, whether parallel operation with main generator(s) or ground power is required, and whether no-break power transfer to and from the APU is required. In some installations the APU may be able to serve as the emergency power source.
