Having flown with the RAF chief test pilot (MOD Source) for their A330 tanker program recently, I know that your information is wrong.... They're only going to have 4 aircraft in permanent use and the other 8 will be flown by civilian operators with the RAF base paint underneath and can be withdrawn from comercial service at any time!! So I think Monarch still have a very decent outlook when it comes to MOD flying..
Can he explain how four FSTA will replace 14 VC10/tri*?
As the UK is paying handsomely for this Gold Plated solution over 27 years, they are going to damn well ensure its utilised fully, that includes ALL charter lift going on these AC as long as it meets qualifying criteria, unless Air Tanker want to turn it down, which would even mean tasks that used to operate on RAF C130s would now travel in style, thats the way the contract has been written and thats what we've signed up for.
say goodbye to your current 'lucrative' work, which always ends up being won by the lowest common denominator anyway.
