Yes but before this change came in we were not getting any tech stops in the first place other than Antonovs and military which still continue so I dont believe it has had any effect on what we currently get. That was what resulted in the place going down to Cat 3 because we were not getting this business like we used to.
If any aircraft were not to stop at Prestwick because of this it would be a flight at very short notice when the fire service cannot accomodate. If they do things properly and read the Notam then they will book with their agent and get PPR to operate within these hours. It is working well enough with our operators, although I fully support an argument for the airport to be open 24H with full fire coverage.
