....hope I am not classed a serial pest
My point has been aired. As indicated subsequently, whilst I do not know the age of the aircraft and its equipment, I point to the intent of the importer and the business decision they must make. Either the cost is purely to meet regulations...and at 400 large appears a tad highball... or, it is an avionics upgrade wish list that has the sky as the limit.
To use this event as an example of bureaucratic intransigent behaviour is fraught with doubts.
