Table 20. Maximum shock specifications
The maximum shock specification of an operational system is six consecutively executed shock pulses in the positive and
negative x, y, and z axes of 40 G for up to 2.3 ms. The maximum shock specification of a non-operational system is six
consecutively executed shock pulses in the positive and negative x, y, and z axes (one pulse on each side of the system) of 71
G for up to 2 ms.

Table 22. Operating temperature de-rating specifications
If the operating temerature of a system is up to 35 °C (95 °F), the maximum temperature is reduced by 1 °C/300 m (1 °F/547
ft) above 950 m (3,117 ft). If the operating temperature of a system ranges from 35 °C to 40 °C (95 °F to 104 °F), the maximum
temperature is reduced by 1 °C/175 m (1 °F/319 ft) above 950 m (3,117 ft). If the operating temperature of a system ranges from
40 °C to 45 °C (104 °F to 113 °F), the maximum temperature is reduced by 1 °C/125 m (1 °F/228 ft) above 950 m (3,117 ft).
