Hello All,

I would like to make sure my understanding of “Roll Rate Integral” in the Roll Angular Rate plot in the flight review log is correct.
Is that for indication of the saturation?
I’m looking for the definition of the “Roll Rate Integral” in a script. Could anyone tell me the location?
Thank you very much for your help in advance.

The “Roll Rate Integral” is the integrator value of the roll rate PI(D) controller. For fixedwing, the integrator of the PI roll rate controller is updated here: https://github.com/PX4/Firmware/blob/37fb4dbb643ad06408f9796963de4b3761098226/src/modules/fw_att_control/ecl_roll_controller.cpp#L108
