EFIS Operation
FlightDEK-D180 Pilot’s User Guide 5-11
(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
FlightDEK-D180. 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
FlightDEK-D180 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 FlightDEK-D180 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 FlightDEK-D180
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, is the maximum positive g-force experienced by the FlightDEK-D180 since reset. The middle row, labeled
CR, is the current g-force experienced by the FlightDEK-D180. The bottom row, labeled MN, is the minimum g-force
experienced by the FlightDEK-D180 since reset.
To reset the max and min g-force values to the current g-force value, enter the EFIS > INFO menu and press the RSET G
button.
