Engine Type Configuration
Within the GLOBAL menu, press DOWN ▼ until you have selected ENGINE TYPE. Press
SEL ► to toggle between LY/CON, ROTAX, and OTHER.
ENGINE TYPE: LY/CON
Setting ENGINE TYPE to LY/CON enables a percent power display for normally aspirated/non-
turbocharged Lycoming or Continental engines. Press DOWN
▼ to select HP RATING and use
the INC+ and DEC- buttons to set the value to the actual horsepower rating for your engine.
Given the horsepower rating, an OAT, fuel flow, and altitude (from a connected EFIS-based
product or GPS), the FlightDEK-D180 will calculate percent power and lean-of-peak/rich-of-
peak status, displaying both next to the Manifold Pressure gauge.
For percent power status to be calculated as accurately as possible, TACHOMETER
(RPM) HI RED/YEL should be set to the RPM value specified by the Engine
Manufacturer. (This is commonly referred to as “Redline”).
If you do not have a fuel flow sender, the FlightDEK-D180 will still display a percent power
reading based on rich-of-peak calculations only. During lean-of-peak operation, percent power is
displayed but is incorrect. While you are in LEAN mode, percent power is not displayed.
ENGINE TYPE: ROTAX
Setting ENGINE TYPE: to ROTAX pre-configures some settings for a Rotax 912 engine. Rotax
914 engines must be manually configured using ENGINE TYPE: OTHER. A percent power
reading will not be displayed, but the FlightDEK-D180 will automatically configure and
dynamically change the oil temperature and tachometer scales and alert thresholds in accordance
with Rotax’s recommended ranges, described in detail below.
RPM / TACHOMETER for Rotax 912:
When OIL TEMP < 120ºF, the TACHOMETER displays these ranges:

0-1400
and
4000-6000 RPM in RED

1400-1800
and
2500-4000 RPM in YELLOW

1800-2500 RPM in GREEN
When OIL TEMP > 120ºF, the TACHOMETER displays
different
ranges:

0-1400
and
5800-6000 RPM in RED
