So guys how do your avionics get from the factory to your aircraft?
The chances are they have gone via one of the major players in the logistics game, be it DHL, UPS, FedEx TNT or whoever I have seen the sorting sheds and the way the boxes are bounced about is far worse than anything that an average landing by chute is going to put on the avionics, if the landing gear and it's mounts are undamaged it is unlikely the avionics will be.
The fact of the matter is the Avionic company's know how they ship their products and build them to take the shipping, however the company lawyers like to build in a little slack to cover themselves, and the best of this is the insurance company is likely to pay them to supply new equipment.
