Cor this hoary old chestnut again.
Who cares about programming the SIDs and STARs except for a veeeeeeeery small minority of sim users, and nothing wrong with that.
Departure and arrival legs are handled by ATC in the sim - you don't have to program them. That's one of the things you
paid for when you bought FS9 and there's no reason for the huge majority of users to go out and buy extra software to plan this kind of flight. So don't give the impression they have to to, to do things 'right'.
Direct GPS is a perfectly OK way to plan this route and as Bill says it gives a track that as close to 'real life' as to make no difference whatsoever to the average simmer.
My plan for a 767-336 gave me a total distance of 5535.2 km, fuel burn of 28610.4 kg and time en route of 5.28 hrs.
Shove the details into your fancy payware and see how different your numbers are!
You don't just take off and go straight onto the GPS track, just as you don't fly direct to LHR and land. You are vectored at both ends by ATC so long as you elect to fly IFR which anyone in their right mind does. That's close enough to a SID and STAR for me thanks very much. And you try flying a different track from the one allocated you by ATC in real life and see what happens!
Obviously there are simmers who want to do things
exactly as per real life, and as I said nothing wrong with that. But you don't have to give the impression that people who don't want to sit there plugging in the numbers (a) are some kind of second-class citizen or (b) get less from the sim.
There you go - got that off my chest.........again
