The days of a dedicated SAR jet sitting on the deck at Kinloss on constant stby have long gone I'm afraid.
Nowadays the aircraft hold airbourne SAR on a 4 hour CT/OpsCT regularly with nowhere near enough fuel onboard to be able to provide an effective top cover if a SAR shout came in.
Even if the jet then landed to get fuel on board the 'constant charge' (CC) servicing that was implemented in recent times has been scrapped due to fuel checks being carried out after every refuel.
I wonder if Joe public would be happy to know of this situation? (mind you thats if they even care)
