2) How does range change with headwind and why
:confused:

I believe that LRC does not change with wind whereas Max range or Cost Index 0 does change with wind. Basically when flying into a headwind the Speed increases and with a tailwind the speed decreases. The FMC on a Boeing calculates this automatically. Old Smokey did a good piece on this a while ago which was a great help in my study for a certain Hong Kong based airline.
