Landing Offset

[Ryan Flynn]

I can pull the data and calculate the landing rate without a problem. However, when is the best time to do this; as soon as the aircraft has landed? 5 seconds after?

If you mean the touch-down vertical speed value in offset 030C, FSUIPC stops changing that value when the "on ground" flag in offset 0366 is set, so all you need do if wait for 0366 to be non-zero, then read 030C.

Don't forget that if the aircraft bounces it will look like a touch-and-go to FSUIPC, so then the value won't stabilise until the final touchdown -- by which time you'll have lost the value you want. One answer to that is to keep reading both 0366 and 030C together, and take the first value of 030C when 0366 becomes non-zero.
