Hi Mark. Thanks for getting back to me. I thought as my query wasnt about the INS, but more how the plane would need to be set up when using it, that the link you gave wouldnt be the right place to post!  :-[ My bad. Thanks for the info about the fuel, its helped a lot.  :)

Sorry aburley.

You are right in saying that it is not an INS question, as a question about the 707 itself, so I apologize if I made it sound like you should have posted it in the thread I mentioned. Because I didn't load the 707 into FSX and take a look at what you are talking about (I was flying a long haul flight in another aircraft and so I couldn't do that). I'll try to take a real soon. ;)
