加速环境中的设备运动
我编写了一个显示俯仰和横滚姿态的应用程序（玻璃驾驶舱应用程序）。当我旋转或倾斜 iPhone/iPad 时，姿态会准确显示。当我乘坐飞机并旋转或倾斜设备时，它也会准确显示。现在，当我将设备靠在面板上并滚动飞机时，姿态不会准确改变 - 它根本不移动。这对我来说是奇怪的行为，我想知道这是否与影响设备中陀螺仪输出的飞机加速度有关。
任何见解都值得赞赏。
I wrote an app which displays pitch and roll attitude (a glass cockpit app). When I rotate or tilt the iPhone/iPad the attitude is displayed accurately. When I'm flying in an airplane and rotate or tilt the device it also displays accurately. Now, when I hold the device against the panel and roll the airplane, the attitude does not change accurately - it doesn't move at all. This is strange behavior to me and I wonder if it has something to do with the accelerations of the airplane affecting the output of the gyro in the device.
Any insight is appreciated.

兰迪，翻滚是一个一重力的动作，对吧？所以手机中的加速度计无法感知到加速度。

Randy, a roll is a one-G maneuver, right? So there is no acceleration for the accelerometer in the phone to sense.
