I tried, but without reproduceable results.
The heading seems to depend on many things like the location of buildings near the landing pad, the airspeed (depends on how far the last waypoint is away) and the terrain. So you may be lucky if it works in a certain setting, but sometimes it just doesn't work and the chopper turns before landing.
Best results I had when doing it on the desert island and by forching the chopper down with "flyInHeight 0", which unluckily isn't enough for my scen. (Here the chopper lands, pilots get out, go to a tent, wait until base is attacked, run to chopper, wait until the general gets in and then fly away)
