MIL-E-7016F
determine the available operating time. If the battery may subsequently be used for
starting, the above operating time shall be calculate so that sufficent capacity
remains for starting. See Figure 15 for example.
Emergency. An analysis of battery loading during the emergency
3.5.5.1.2
condition shall be made to determine the time remaining during which electrical
power will be available.
Engine starting - electrical requirements. The power require-
3.5.6
ments for engine starting shall be defined as follows:
Engine starting requirements data.  The current drawn, minimum
3.5.6.1
potential required, and other pertinent data should be shown in a manner such as
the example on Figure 16.
Starting power service data.  The identification and rating of the
3.5.6.2
recommended source of power for starting should be given in a manner such as the
example on Figure 16.
Peak starting requirements (common bus). If the loads nor-
3.5.6.3
mally "ON" during start and warmup are connected directly to the starting power
source during the engine starting, the analysis shall be continued as follows:
a.
Start and Warmup:
amperes/VA
5-second average load,
amperes/VA
5-minute average load,
amperes/VA
Continuous average load,
Note:
The above results shall be taken from the "Start and
Warmup" operating conditions chart, Figure l1.
The possible system peak is the sum of the peak starter
b.
load plus the 5-second average load from a. above.
The probable system peak is the sum of the peak starter
c.
load plus the 5-minute average load from a. above.
3.5.6.4
Self-powered engine starting. If the aircraft is capable Of
self-powered engine start, the starting requirements shall be reported under the
start and warmup operating conditions for analysis with respect to the internal
power source.
Ground power.  The following information shall be furnished
3.5.7
which pertains to ground operation with an internal auxiliary power unit, with
external power or both See Figure 17.
