Hello Juaxs,
1.Firstly, we will not recommend to use BNO055 to measure the attitude angles of real aircraft. 2.Secondly, not only accelerometer, but also gyro would be influenced by the external force. usually, the g-sensitivity of the consumer gyro would be around 0.1deg/s/g, which means when you give an external force like 0.3g to the gyro, the bias on it will increase for 0.3deg/s. And that will influence the output angle accuracy. 3.Thirdly, the sensor fusion algorithm needs the inputs from accelerometer, gyro and manetometer. Even you use a gyro with a good g-sensitivity, the output angles are still influenced a lot by the value change of accelerometer due to the external force.
