“Dist. Reserve:” Distance you can fly beyond your Way Point based on current Distance to Empty and
Distance to Way Point. If the Time Reserve drops below 45 minutes, this value will be displayed in Yellow. If
the Time Reserve drops below 30 minutes, this value will be displayed in Red.

4.5 “Timers” Screen:

The “Timers” screen provides the following timers:

“Up Timer:” An Up Timer is provided with a recurring
alarm. If the alarm is set for 30 minutes, you will get an alarm
every 30 minutes (i.e., 30 min, 60 min, 90 min, etc.). This can
be useful for timing the switching of fuel tanks, periodic
checkups or other important events. A field for starting,
stopping and resetting the timer is provided. When the alarm is
activated the digits for the timer will blink in yellow and the
external Caution Light will blink until acknowledged by pushing
any button.

“Down Timer:” A Down Timer is provided with a field for
starting, stopping and resetting the timer. When the timer
reaches 00:00 the digits will blink in yellow and the time will start counting up with a negative sign shown in the
front of the displayed time.

“Flt Timer:” The Flight Timer automatically times each flight. The Flight Timer is reset and started when the
RPM exceeds 2000. The Flight Timer is stopped when the RPM drops below 1200. The start and stop
RPM settings may be changed in the “Engine Type, Ports, Timers, etc. Setup” screen. To the right of the
displayed Flight Time is the status of the timer.

“Upper Timer Display” and “Lower Timer Display”: There are two timers displayed on the Main Engine
Instrument Screen just under the RPM and Manifold Pressure instruments. The timers displayed in these two
locations may be selected in the Upper Timer Display field and the Lower Timer Display field.

“Voice File (OEM and Experimental):” The Voice File field allows you to select the voice to be activated
when the Up Timer reaches the reoccurring alarm and/or the Down Timer reaches 00:00.

4.6 “Clock and Hour Meters” Screen:

The “Clock and Hour Meter” screen displays Today’s Date, Local
Time, Zulu Time (UTC), Tach Time and Engine Hours. In most time
zones, the minutes portion of Local Time will be the same as the
minutes portion of Zulu Time. For these time zones the MVP allows
you to lock Local minutes to Zulu minutes.

Note: Today’s Date and Local Time are used to time stamp stored
engine data records.
