The exit fuel is something we want to look at after a bit of operational use. It isn't an issue if the tanker and receiver are going to the same location as you set the exit point at TOD and then work the fuels from there, exactly as we did for AARWIN. Remember, AARWIN only worked to the overhead and didn't automatically account for descent and approach. It shouldn't be too hard to work out the transit fuel when not co-located either, let's face it, it's just a speed distance time calculation to TOD.
But as I have said, it may be something that we change in the future if the need arises. What we need to do is get on with using it and see how we go.
Beags, I am as frustrated as you that the industry partners didn't get involved, especially ATr as only they really had the power to change the design philosophy behind the MPS, but unfortunately not many of the board had any AAR planning experience.
