Station passage

[pve 0]

Hi all In my FMC using a loaded FS flight plan I want to trigger Wpt passage same time as the GPS. Using (A:GPS IS ACTIVE WAY POINT, bool) (A:GPS WP DISTANCE, nmiles) 3 < if{. Can't use less than 3 miles as it seems altitude distance to waypoint is included. Can any one help.pve

I use GPS only rarely (I'm old and therefore old-fashioned ;-), but the one thing I've noticed when flying a GPS flightplan is that the point in time when it flips over to the next waypoint seems to be dependent on not just distance, but speed too. It's probably a "time to" kind of function. Fly a sample flightplan, take note of your speed and the distance to the waypoint just before it flips over, and you can then compute the "time to" that FS uses. You can then make your code match. Let us know what value you get. ;-) I have often wanted to change this myself, to make it wait a bit longer before switching to next waypoint.... >>Hi all> In my FMC using a loaded FS flight plan I want to trigger Wpt>passage same time as the GPS.
