RNAV tracking issue southbound
-
Good Morning,
There is an issue that i come across, time and again. At some point the aircraft has trouble tracking the route in RNAV. Or maybe that´s not quite correct. It DOES track the route but leans to the side at almost full rudder deflection as if there was a massive Xwind. Which is even more peculiar given the fact that the Autoflight system has no rudder control authority as far as i recall... Switching to HDG mode mitigates the problem. But if I stay in LNAV and use the Sync-button on the yoke the plane starts rocking around like crazy until i recover it. Yesterday the autopilot didn´t even want to work afterwards wich resulted in me handflying the STAR
Anyways, yesterday on a flight from EDDH to LIMJ i seemed to have found the common denominator in this issue, which has always been tracking southbound when it occured. Call me crazy but it seems to be worse over central europe as everything looked fine after departing Hamburg until way into the flight...
Can anybody of you guys confirm such behavior???
Have a nice one,
regards
