SECTION 3, OPERATION GUIDE
3.1 PRE-FLIGHT PROCEDURES
During pre-flight procedures, the instrument must be provided with adequate electrical power under normal vibration conditions
(engine running). A red “X” appears across the screen indicating that the instrument is booting up. When the X disappears, the
instrument is ready. The startup process should be completed within three minutes.
When applicable, check that the Battery Charge Status Indicator displays at least 50% charge to ensure a minimum of 30 minutes
of operation in the event of a power failure.
NOTE
On tail-dragger aircraft, the indicator will not show as level until after achieving level flight. No adjustment are
necessary when level flight is achieved.
3.2 IN-FLIGHT PROCEDURES - PITCH SYNC
(Selected models only)
If you typically fly in a “nose down” or “nose up” pitch attitude , you can adjust the Airplane Symbol to match the Horizon Line on your
instrument. The Pitch Synchronization (Pitch Sync) feature allows you to instantly sync the Airplane Symbol to the Horizon.
NOTE
This feature is not necessary for most aircraft and is to be used only in situations where normal flight pitch is
deviated from 0 degrees.
PITCH SYNC ACTIVATION
Once you have achieved the desired flying pitch, activate the Pitch Sync feature by pressing BOTH PUSH BUTTONS simultaneously.
This synchronizes the Airplane Symbol to the Horizon Line.
The Sync ‘On’ indicator will display “SYNC” when the Pitch Sync is activated (see figure 3.1).
PITCH SYNC DE-ACTIVATION
To return to True Pitch, press BOTH PUSH BUTTONS simultaneously. This moves the Airplane Symbol back to True Pitch Indica-
tion and the Sync ‘On’ indicator will disappear.
EXAMPLE
In the example shown in Figure 3.1, The aircraft is flying level at a 10 degree nose down pitch with the Pitch Sync on. The Sync
‘On’ Indicator is being displayed. The True Pitch Horizon is indicated by the bottom Tick Mark on the Roll Dial which is aligned with
the 10 degree mark on the Pitch Dial. The Airplane Symbol is shown aligned with the Horizon Line at 0 degrees on the Pitch Dial.
