Like a conventional gyro-stabilized magnetic compass, magnetic heading reacts immediately to turn rate so that heading
changes are reflected immediately. It then uses magnetometer data over the long term to ensure that it remains correct.
Additionally, heading is corrected for attitude so that it is accurate as you pitch and roll.
Turn rate indicator
Centered just below the heading digital readout, the turn rate indicator displays the
aircraft’s current rate of turn with respect to the ground. The magenta bar grows in the
direction that the aircraft is currently turning, and is anchored at a white vertical anchor
line. The brackets on either side of the bar’s anchor line represent the turn rate which
results in a standard rate turn. Turn rate takes attitude into account. This means that even wh
still shows rate of turn in relation to the aircraft’s heading.

The turn rate indicator is scaled to indicate a 6-second heading trend. In the example above, the trend indicator is
showing that the aircraft will be pointed at 40º in 6 seconds if the rate of turn does not change.
Altitude tape, digital readout, and VSI
The altitude tape scrolls beneath the altitude digital readout and arrow. The digital readout’s digits scroll
up and down, simulating an analog altimeter and giving a sense of the direction of movement. Thousands
of feet are displayed using large numbers while hundreds of feet are displayed in smaller numbers. The
EFIS-D10A accurately displays altitudes from -1200 to 30,000 ft (-365 to 9144 m).
The graphical Vertical Speed Indicator is located next to the altitude tape. The magenta bar grows in the
direction of – and in proportion to – the rate of climb or descent. The numbers on the scale represent
thousands of feet per minute. In the CLUTTR menu, the VSI scale can be set to display 1000 ft/min, 2000
ft/min, and 4000 ft/min. The 2000 ft/min scale is linear throughout the range, while the 1000 ft/min and
4000 ft/min are non-linear as shown on the scale. When set to display 2000 ft/min, the VSI bar is scaled to
indicate a 6-second altitude trend based on its position with relation to the altitude bar. When set to display
