Good afternoon,a) Nothing in the doc, as I read it, desagrees with my previous post.As a matter of fact, on departure, ramp position remained waypoint 1 for two raisons:1) No need to delete it.2) Might have been useful in case of an emergency.Keep in mind INS did appear on the late sixties.b)Before linking th INS to the FD/PA:1)Upon cleared in route by the ATC make a waypoint change (0-2 for example) 2)Check the distance to go and the turn angle.3) If everything is correct, activate the INS.4) In case of a wide angle of turn, make a second track change (0-2 in our example) near the end of the turn to avoid overshooting.Best regards
