Peterh337 - yes, but if you work the calculation without taking into account the defamation of the honeycomb under the seat at a descent rate of 1500 fpm the cockpit is only experiencing a g loading of between 2 and 4. We commonly sustain this level of g during basic aerobatics and its not unusual to experience +8 or more. Perhaps the avionics are suffering much less g than one might think after a chute deployed landing. I have no idea at what g level one could expect damage to occur to pcbs etc.
