4.3.1.2.2 Demonstration of aircrewmember population range accommodation.
For each aircrewmember station, the contractor shall demonstrate compliance
with the requirements of 3.2.1.1.
4.3.1.2.3 Demonstration of aircrewmember capability to reach and actuate
aircraft controls. For each aircrewmember station, the contractor shall
demonstrate compliance with the requirements of 3.2.1.2.
4.3.1.2.4 Demonstration of aircrewmember capability to reach and actuate
escape system controls. For each aircrewmember station, the contractor shall
demonstrate compliance with the applicable requirements of 3.2.1.3. The reach
requirements of 3.2.2.10.1 and 3.2.2.10.2.1 shall be demonstrated.
4.3.1.2.5 Field of vision. Field of vision plots for each aircrewmember
station shall be made available as part of the compatibility demonstrations.
The effect of each occupied ejection seat assembly and other system components
upon the field of vision for each aircrewmember station shall be depicted upon
field of vision plots in accordance with the procedures specified in MIL-STD-
850. Plots shall be made quantitatively with the Field of View Evaluation
Apparatus (FOVEA) in accordance with NATC report SY-126R-78. In a multi-seat
aircraft, the FOVEA shall be positioned at the design eye position for the
ejection seat assembly being evaluated. The other ejection seat assemblies
within the aircraft at the time of plotting shall be occupied and in the full-
up position.
4.3.2 Engineering proofing article II (EPA-II} review. The EPA-II review,
which includes the escape system fit and compatibility evaluation (see 4.3.2.2)
and the audits and reviews specified in 4.3.2.1, 4.3.2.3, 4.3.2.4, 4.3.2.5,
and 4.3.2.6, is a detailed evaluation of the proposed design and configuration.
Limited DT-IIA testing may be authorized by the procuring activity prior to
final acceptance of the EPA-II review. At least 60 days shall be allowed
after the completion of DT-IA testing (see 4.3) to provide sufficient time
to gather data for and to complete the IFCA (see 4.3.2.1) prior to the
commencement of other EPA-II events.
Initial functional configuration audit (IFCA). An IFCA of the
4.3.2.1
escape system shall be conducted by the contractor in accordance with MIL-STD-
1521 prior to the commencement of other EPA-II events. A summary of the
results of the DT-IA tests, as documented by the individual development test
reports, shall be made available to the procuring activity (see 4.7.3.4).
The objective of the IFCA will be to verify that sufficient data has been
generated and that compliance with functional and performance requirements
have been demonstrated by DT-IA testing before preceding to DT-IIA and
DT-IIB. Concurrent with the conduct of the IFCA, a qualification status
review shall be conducted by the contractor as a follow-up to the IQSR of
4.3.1.1.
4.3.2.2 Escape system fit and compatibility evaluation. A proofing
article(s) shall be installed in the aircraft or an aircraft cockpit mock-up
acceptable to the procuring activity for evaluation of escape system fit
and compatibility with the aircraft and for evaluation of aircrewmember
