744 GS calculations
Was looking at the prog page the other day, and the figures were something like...
TAS 495 kts
T/Wind 160 kts
and the GS on the ND said
GS 665 kts
All figure for illustrative purposes, but in a nutshell, the GS indicated GREATER than the total of TAS and T/wind by about 10 kts. FWIW wind was coming from our 7 o'clock.
It would seem to do with vector triangles, but be damned if I can figure it out.
