Chickenhouse
This is an interpretation of the new regulations that is quite frankly stupid and overly restrictive............. What you are telling me is that if an aircraft with a 760 channel radio has a problem with that radio away from base it can't be fitted with another 760 radio of the same part number to let it fly back to base....... In effect grounding the aircraft.
I can only think the people pushing this interpretation of the new regulations have lost all reason or are in the business of selling 8.33 & mode S equipment.
This is not the interpretation the UK CAA put on the regulations, in the UK replacement of one radio with another of the same part number is not considered a change of equipment......... Just a unit change.
With this sort of nonsense from Europe you can see why the Brits want out of the EU.
