View Full Version : Autopilot Off Course
10-01-2005, 11:41 PM
While flying with autopilot active, the aicraft is flying off course. It's not winds that's knocking if off course. The aircraft will make turns flying several miles off course, before returning on course. It seems as if it's reading something on the course that's pulling it off course.
Does anyone know how I can correct this short of reinstalling FS9?

Actually, i'm having the problem with all aircraft. It's really weird. I'm currently flying from KCLE to KDCA and have gone far off course. Not certain what's causing this at all!

Have you set your DG ("D" key)? What method of navigation are you using (GPS, VOR, FMS,...)? What did you use to set your flight plan? Are you in NAV mode? Is the NAV/GPS switch set to the appropriate position? What add-on nav stuff do you have installed?

Actually, I've pressed the D key several times. I always use the GPS, I used the Flight Plan in FS9 and filed an IFR flight plan. The Nav/GPS switch is toggled to GPS and I haven't added any nave stuff. What else could it be?
There are many kinds of 'directions' in aviation:
-course refers to a VOR - It's based on the VOR's lokal orientation
-when navigating on GPS, you generally follow a (ground based)track
-your aircraft's nose is pointing in some (magnetic) heading
Those 'directions' may or may not have different values. It depends where you are flying: near the magnetic north pole, heading and course can be very different.
You say, your aircraft (quote) 'will make turns flying several miles off course, before returning on course'. Could it be that the radial you dialed into your autopilot is not similar to the heading you want to fly?
If this is completely beside the point, please just ignore this post! However i would definitely wait and see if things have some kind of explanation before I'd start reinstalling FS9.
"Artificial flight may be defined as that form of aviation in which a man flies at will in any direction, by means of an apparatus attached to his body, the use of which requires dexterity of the user."
Otto Lilienthal, 1895
