EFIS Operation
INFO – Informational Items
In the EFIS > INFO menu, you have the option of displaying
an informational display item on either the left or right side, or
both. You may display a voltmeter (VMETER), g-meter
(GMETER), vertical speed indicator (VSI), OAT/true
airspeed/ density altitude (OAT), and engine RPM/MAP info
(ENGINE). More detail about each of these is given below.
Voltmeter
The voltmeter displays 3 rows of information corresponding to the three power inputs on the EFIS-
D10A. The first row, labeled M, displays the Master Switch voltage. The second row, labeled E,
displays your optional external backup voltage. The third row, labeled I, displays the EFIS-D10A
internal battery voltage. If any of the 3 voltage inputs are not present, 00.0V is displayed for the
respective voltage values. The letter V follows all three values, denoting the fact that voltages are
being displayed. The EFIS-D10A alerts you when the internal battery is low by displaying a low battery alert.
G -meter
The g-meter displays the current vertical acceleration experienced by the EFIS-D10A measured in
g’s, where 1 g is the amount of acceleration due to the earth’s field experienced by an object at sea
level. Positive g-force is defined as upward vertical acceleration, making you feel heavier.
Negative g-force is defined as downward vertical acceleration, making you feel lighter. As can be
seen in the picture, there are three rows of text that make up the g-meter. The top row, labeled MX,
