20 Hz and 27.5 0.5 VDC
Service Conditions - The equipment shall operate satisfactorily
3.3.10
under any of the environmental service conditions or reasonable combination
of these conditions as specified in Specification MIL-E-5400 for Class 1A
equipment, except as modified herein:
*
3.3.10.1 Vibration - The equipment shall operate to the requirements
of this specification when subjected to the vibration requirements of Curves
I and II of Specification MIL-E-5400, except as modified below:
(1) Curve I shall be limited to 5g.
(2) The Tactical Display Control shall meet Curve I
or 5 g's, whichever is less, for X and Y axis; and Curve
I and III from 5 to 160 Hz, 2 g's from 160 to 400 Hz,
5 g's (Curve 111) from 400 to 500 Hz for Z axis. Cross-
over points 160 Hz and 400 Hz (Z-axis Tactical Display
Control Unit) are not considered resonances.
3.3.10.2 Temperature - The minimum temperature for satisfactory per-
formance to the requirements of this specification shall be -30C. The
battery contained in the Battery Unit shall not be subjected to temperature
less than -40C or greater than +55C. Battery protection for power inter-
ruptions shall not be required at temperatures below -15C, or above +45C.
Warm-Up Time - The time required for the equipment to warm
3.3.11
up prior to operation shall be kept to a minimum and shall not exceed 3 minutes
under standard conditions, and 5 minutes at -30C.
Alignment time for the Inertial Measurement Set is not
included in warm-up time.
Input Electrical Power
3.3.12
3.3.12.1 Operating Power - The equipment shall meet all applicable
requirements of MIL-STD-704 and shall give specified performance when
energized from the following power sources having characteristics and limits
as defined in MIL-STD-704, except as modified herein. The power required shall
not exceed the specified amounts.
