Measuring G Force

ArduPlane Plane 3.8
1

I would like to have an idea about the G force, I mean acceleration and decelaration, that my plane get when I fly fast , do a nosedive, catpult launch or land .

What are in the dataflash log the data to look at ?

IMU.AccX IMU.AccY IMU.AccZ

Also IMU2 equivalents.

Gave a rapid try and It works , thanks !

old post but usefull.
can you please guide me on converting imu.accx,y,z in vertical g force ?

thanks

IMU AccZ (vertical) is gā€™s, units m/s^2

6

Divide by 9.8 to get a result in ā€œgā€™sā€

the idea is to check if z accel is correlated with thermals (soaring). It is of course but it could help to detect thermals before variometer.
