Hi,Is there a way to see the glideslope become active and move when the "gps drives nav1 switch" is on?I mean it is good to know when to switch from gps to approach mode.If all possible it could be automated in an autoland situation.Jan"Procul Negotiis"

Jan,Use:(A:NAV1 GS FLAG, bool)This flag works independant of the NAV/GPS switch postion.Rob

Rob,Thanks, but the GSI needle remains "pegged" in the middle.I need to see an alive glideslope, using (A:HSI GSI needle, number)Jan"Procul Negotiis"
