October 15, 201510 yr Folks, this may have been addressed moons ago but yet to find a remedy. My pre-defined altitudes are plugged in and autopilot engaged; however, when the altitude is reached the Altimeter dances up and down and won't level the aircraft to the pre-defined altitude entry. I usually click autopilot button a few times until the altimeter "calms down" and finally catches the altitude and levels but that is annoying. I noticed on my Vistaliners 727's and DC-9's and some others but would like any input on what to adjust in Aircraft config or is it something else?..can't find a solution yet... Your input always appreciated! Respectfully, Chris Retro "junky" :-)
October 15, 201510 yr Administrators How high of a cruise altitude? Pitot Heat on? I thought I would start out with the easy things to check.

October 15, 201510 yr Author Cruise altitude usually between 26k and 27k Pitot Heat is off... Thanks for replying..it's probably something staring me right in the face to adjust but can't put my finger on it....:-)

Gets cold up there on occasion. :wink: Charlie AronAVSIM Board of Directors-ADMIN/Moderator-RegistrarJust going to run a Chromebook and not upgrade to a Windows computer.

Assuming you have A/T engaged, could small computational errors in that be affecting the thrust slightly, thus causing the instability? See if it's okay much higher or much lower.
