Air performance

Edit: these may be in error, see my next post.

If it’s of any interest, these are the formulas I came up with for Spaceships air vehicles based on the (also not perfect) VE2 formulas and some reasonable assumptions about shape and area. It ended up simplifying down to only needing length in yards and Accel. in G to calculate. Note this is the length from the hull size chart, not the adjusted length based on streamlining — I was aiming for ease of use, so there are conversion factors already built in.

Stall Speed = square root of length * 36
Top Speed = square root of (length * Accel. * 600,000)

Again, these give results consistent with VE2, which is not actually physically accurate but is good enough to be plausible for a game.
