3.5.4.1.4.3
Ac phase identification. Loads supplied from wye-connected
sources shall be entered under phases A-N, B-N and C-N. Loads supplied from
delta-connected sources shall be entered under phases A-B, B-C and C-A. Loads
supplied from single-phase sources shall be entered under the phase to which it is
reflected, with an appropriate note.
3.5.4.1.5
Dc amperes per unit - Column E. Dc power requirements shall
be stated in amperes, measured at nominal system voltage, Entries shall be the
average current drawn by the equipment over the operating time. Transient and in-
rush currents shall be analyzed in accordance with 3.5.4.3.
3.5.4.1.6
Load operating time - column F. The load operating time is
the time in minutes for which each item of equipment draws electric power in each
operating condition. If the operating time varies in a manner which cannot be defined
satisfactorily with a simple unit of time, an explanation shall be included in the notes.
Operating times of O. 005 minute or less shall be entered as "O". Operating times
greater than 0.005 but less than 5 minutes shall be entered to the nearest 0.01
minute. Periods longer than 5 minutes are considered continuous; enter "C" as on
Figures 4 and 10.
No entry shall be made for equipment used only
Exception:
during engine starting.
3.5.4.2
Load analysis charts- column G. The load analysis charts are used
to determine the total load requirements for each condition under which the aircraft
operates. The operating conditions listd in the following paragraphs are considered
typical for most military aircraft. The conditions shall be reported and analyzed in
the order corresponding to a typical operation of the particular aircraft. Special
conditions applicable shall be reported in additional operating condition columns. The
charts for each operating condition shall be designated G1, G2, G3 . . . consecutively
for a normal operating sequence. See Figures 5 and 11 for sample load analysis charts.
3.5.4.2.1
Ground maintenance. Ground maintenance is that operating con-
dition existing when electric components are being repaired, checked or tested, and
electric power is supplied by internal or external power source(s). The electric
loads reported shall include the maximum power requirements of all loads or groups
of loads which may be operated simultaneously during maintenance operations.
3.5.4.2.2
Calibration. Calibration is that period when equipment is be
checked for accuracy or recalibrated.
Exception:
The condition of calibration may be omitted when
each electric equipment in the aircraft can be
calibrated with (1) power having the characteristics
specified in MIL-STD-704, and (2) the ground
power source required for the ground maintenance
