I doubt that the arrangements made by South Yorkshire to retain their aircraft will save them any money at all
From the NPAS figures..
Option 3 (10hrs per day own a/c) = 1.686 million pounds
Current cost of running own unit = 1.68 million pounds..
So the NPAS "deal" they have struck actually costs 6000 pounds per year MORE
For the 6K extra they get the privilege of only using the a/c that they OWN for ten hours a day, lose half their pilots, all their engineers, and half their cops..
Oh yes but they get 24 hr cover from NPAS..
(ah but they are in a mutual aid consortium already where they are provided with..... yes you guessed it.. 24hr cover...!!! )
So the sum total of the gains from joining NPAS = zero..
