    Re: Two body Sandwich Fix Proforma

    Now that I understand what is going on with the "sandwich fix" I have to ask the question, "why?" It looks like a lot of work, what was the payoff? Was it thought to be more accurate than the standard three body fix which had the standard MOO, MOB, Coriolis, rhumb line, wander and groundpeed  corrections applied?

    Attached is an RAF two body sandwich fix proforma at 276KB (larger available).  Clearly not every box had to be filled in for every body.  I’m still trying to work out why we used IAS change and not TAS change.  Perhaps the 6 in the ‘Sum’ column allowed for it.  At high level Mach .84 always seemed to be 480kts TAS and 240kts IAS. When I get time, and after I find my Mear’s slide, I’ll fill one in with fictitious values if I can remember what all the boxes were for.  On the reverse was a three body sandwich fix proforma. That must have been really complicated.  Dave
