On-Screen Elements
The D2 is primarily a portable backup attitude indicator but also has a second screen that displays
the aircraft load factor (G meter). Switch between the two displays with a press and release of
the menu button.
Aircraft Attitude is determined
by combining information from
internal solid state rotation rate
sensors (gyros) and
accelerometers. GPS
information is additionally used
to ensure the quality of the
displayed attitude indication.
Like a mechanical attitude
indicator, the artificial horizon
depicted on the D2 screen
displays both the pitch and roll
of the aircraft.

Pitch angle is read by noting the position of the indexed pitch ladder against the centered yellow-
outlined black square. There are extended pitch cues, also in yellow-outlined black to the left and
right of the primary aircraft pitch indication. In the example above, the aircraft is pitched up
approximately 1 degree.
