3.5.4.2.10
Emergency. Emergency is any period of flight during which
the normal sources of power are inoperative. During this period, loads essential
to safety of flight under any flight condition are transferred to an alternate source of
power. These loads are listed in the emergency column, and the total load require-
ments are analyzed with respect to the alternate power source. Possible categories
of essential electric loads are flight instruments, surface controls, engine controls,
and fuel boost systems. If the emergency power source is a battery, see 3.5.5.1.
Exception:
For rotary wing aircraft having at least two
separate primary sources driven by the rotor
transmission and at least two secondary sources,
where a single primary or secondary source can
supply all essential loads, the emergency condi-
tion shall be omitted and replaced by analyses of
the loads and source capacities remaining after
a single failure for each type of power source.
3.5.4.2.11
Mission completion. Mission completion power is defined as
minimum electric power required to enable an aircraft to complete its mission The
requirement for this power may occur during any period of the flight. For a multi-
engine aircraft the load shall be compared to the power source capacity remaining
after loss of any one generating or conversion system. For a multi-role aircraft, the
mission requiring most electric power shall be chosen for analysis.
3.5.4.2.12
Additional columns. Additional columns may be used as re-
quired to report special operating conditions which may materially affect the load
analysis by indicating conditions more critical than those specified. These condi-
tions might include any of the following:
Ground Alert
Equipment Warmup
Idle Descent
Hovering
Loiter
Jato or Rocket Ignition
Launch
3.5.4.2.13
Combination of columns. Where load requirements for one
operating condition as specified under 3.5.4.2.12 are identical to those of one or
more other conditions, they may be combined into a single column with a suitable
heading denoting these conditions.
3.5.4.2.14
Average Load - subcolumns. For each analysis other than
continuous analyses, the average watts and average vars ac entries, or average
amperes dc entry, for each load for which the operating time is less than the time
