B737-800 nose pitching up too much during take-off run
« on: May 21, 2018, 08:59:24 PM »
My B737-800 sim, based on P3Dv2 was going fine for a long time. Having a nice flight one day, the next day something strange happened. First I noted that the nose was dipping down a lot during braking and coming to a stop. While powering up for the take-off the nose pitched up like rotating. Pushing the stick forward did not solve the high pitched nose.
Does anyone knows what controls this and how to solve this ?

Most likely this is caused by the dynamic head movement section in your Prepar3d .cfg file.

The parameters can be adjusted by changing the values.
For example:

[DynamicHeadMovement]
LonAccelOnHeadLon=0
LonAccelOnHeadPitch=0. << likely the cause
RollAccelOnHeadLat=0
YawAccelOnHeadLat=0
RollAccelOnHeadRoll=0
MaxHeadAngle=0
MaxHeadOffset=0

See this... http://www.prepar3d.com/SDKv2/LearningCenter/utilities/camera_configuration/camera_configuration.html#Dynamic%20Head%20Movement

Changing all values to “0” stops all movements.
You must change the values and not just comment these out with // or deleting them as P3d will write them back in if you do that.

A reboot may be required after the change.

Thank you for the well appreciated information. I will give it a try and see what the current values are and adjust to get it back as it was before.
