EFIS Operation
FlightDEK-D180 Pilot’s User Guide 5-7
Entering the EFIS > SETUP > CLOCK menu displays the local and Zulu times in the value-setting box. Because local
time is usually an offset in hours from Zulu time, set the minutes value in the Zulu time portion of the box; notice that
the local time minutes setting change at the same time. Then, set the hours for local and Zulu times independently. Once
you have set Zulu time, you should never need to change it, as it is independent of daylight saving time. When connected
to a GPS which is outputting time information, Zulu time is synchronized to the GPS and cannot be set on the
FlightDEK-D180.
In a DSAB network, you can only set the Zulu time on the DSAB master, and only if it is not synchronized to
GPS time. You can set the local time on all units individually.
To change the local clock when moving through time zones or to enter daylight saving time, simply change only the
hours (and, if necessary for the time zone, the half-hour offset) for the local time. Be aware that connecting to the
FlightDEK-D180 with the Dynon Product Support Program resets the time; do not set the time until you have performed
all of the PC interface operations. Refer to the following set of tips as you set the clock:
• Set both the local and Zulu times in military time. You have may display the time in either military or standard
12-hour format, as described below.
• SEL► moves the highlight to the next set of digits. The order of selection is 1. Local hours, 2. Local minutes
(adjustable only as ½-hour offsets from Zulu minutes), 3. Zulu hours, 4. Zulu minutes. When connected to a
GPS, you are not permitted to adjust the Zulu time on the FlightDEK-D180
• DEC- and INC+ change the selected set of digits. To speed up the process, press and hold the desired button. If
you pass the desired value, you may simply back down to it by pressing the button corresponding to the
opposite direction.
• Incrementing or decrementing the minutes digits resets the second count.
