MIL-A-81573(AS)
initiation for constant aircraft bank angles of 0, 30, 60, 90, 120, 150, and 180
degrees each. It shall not be necessary to show curves for both right and left
bank attitudes unless performance characteristics of the aircrew escape system
will produce significant differences between the terrain clearance requirements
associated with equal magnitudes of right and left bank. The curves shall be based
on the worst results obtained from either right or left bank attitudes.
3.2.2.6
Landing and Take-off Escape Capability- As shown in Figure 6,
this chart shall depict the normal climb out and approach, as well as the no thrust
approach curves for the aircraft. Superimposed upon these curves shall be shown
the safe and unsafe regions based upon aircrew inflight escape system performance
characteristics. Separate charts shall be prepared for (a) wings level and 30
degrees bank, and (b) 45 and 60 degrees bank.
Data -
3.2.2.7
3.2.2.7.1
Data sources - The data required for developing the aircrew
escape system performance data presentations specified herein shall be derived
from, or extrapolated from, data obtained during escape system tests specified
by MIL-E-9426, MIL-S-18471, MIL-A-23121, and MIL-STD-846, as applicable.
The use of computer simulations based upon, or verified by, data generated during
the escape system tests to develop these presentations is encouraged.
3.2.2.7.2
Escape system weight - In developing the herein specified air-
crew escape system performance data presentations, the weight of the escape
system shall represent the total for fully-equipped 98 percentile aircrewman(men)
and the portion of the aircrew escape system boosted from the aircraft.
Esca pe system center of gravity - The escape system center of
3.2.2.7.3
gravity used in developing the aircrew escape system performance data presenta-
tion herein specified shall represent worst extreme conditions as determined
during test and evaluation of the escape system.
Aircrew reaction time - The aircrew escape system per-
3.2.2.7.4
formance data presentations shall include both pure data (showing performance
measured from time of escape system firing control actuation) and data allowing
for a 2 second aircrew reaction time between realizing the need for escape and
actuating escape system firing controls.
Completion of aircrew egress - Aircrew egress shall be con-
3.2.2.7.5
sidered complete when the last aircrewman or escape system has cleared the
adjacent aircraft structure.
