D3 Pilot’s Guide 6-16. PERFORMANCE NOTESAttitude PerformanceOptimal attitude performance depends on a number of environmental factors:GPS REQUIREDThe attitude indication provided by the D3 is primarily created by combining information fromsolid state MEMS-type accelerometers and rotation rate sensors, and supplemented by GPSground speed. In order to display as reliable an indication as possible, a GPS fix is required. The D3will not display attitude until it has obtained a GPS fix. Once a GPS fix is obtained, it is importantthat the GPS fix be maintained by either mounting the D3 in a position that affords it a good viewof the sky, or, if that is not possible (such as when using the pinch mount to panel-mount the D3),using the included external GPS antenna.LOSS OF GPSThe D3 requires a GPS fix to display attitude, speed, altitude, vertical speed, ground track, andvertical speed. The D3 can cope with momentary degradations in GPS signal quality. Afterapproximately 2 after the loss of GPS signal, the above flight instruments will become inoperativeand removed from view.ROTATION RATE LIMITThe D3 will operate normally with rotational rates of up to 150 degree per second around anyaxis. If a rate of 150 degrees per second is exceeded, HORIZON RECOVERING will be displayedalong the bottom of the display. The D3 will continue to display attitude information, but it shouldbe cross-checked against other instruments while in this recovery mode. After a few seconds of
