ROTATION RATE LIMIT
The D1 will operate normally with rotational rates of up to 150 degree per second around any
axis. If a rate of 150 degrees per second is exceeded, HORIZON RECOVERING will be displayed
along the bottom of the display. The D1 will continue to display attitude information, but it should
be cross-checked against other instruments while in this recovery mode. After a few seconds of
straight and level flight, the HORIZON RECOVERING message will automatically disappear when
the D1 is confident that it is showing the correct attitude.
