If it is true that the P68 does not meet requirements there is a conundrum in that it has passed the EASA FIKI.
If it has FIKI I would assume it meets all aspects....and yet the suggestion [well much more than that] is that there is an element of the flight envelope it does not meet.
So a suspicion is emerging that face saving might be the order of the day.
As FIKI is a small part of the mission there is at least a possibility that the aircraft could enter service and do most of the mission and thereby avoid entering the 'missing' parameter. Avoid flying on damp and cold winter days and nights.
That would save face and it is unlikely to emerge for a few years in which time a replacement airframe might be acquired.
I accept this theory is full of holes but on one hand I understood that there was not a snowballs chance of it meeting the spec and yet another source has suggested that it will enter service later in the summer.
