Stop using "CAP". Use BARCAP or TARCAP instead.
TARCAP no longer allowed anywhere but front lines, since that's all we
have mission planning for right now. Later will add TARCAP and BARCAP
for all objective types with different timing profiles.
Part two of the fix for
https://github.com/Khopa/dcs_liberation/issues/210.
Reasonable ground speed depends a lot on altitude, so plumb that
information through to the speed estimator.
Also adds calculations for ground speed based on desired mach. I don't
know if DCS is using the same formulas, but we should at least be
pretty close.
We estimate the longest possible time from mission start to TOT for
all flights in a package and use that to set the TOT (plus any delay
used to stagger flights). This both cuts down on loiter time for
shorter flights and ensures that long flights will make it to the
target in time.
This is also used to compute the start time for the AI, so the
explicit delay option is no longer needed.
