Remote Auxiliary Display Basics
The Remote Alarm Display ‘RAD’
provides alarm display, RPM and MAP,
and is located directly in front of the pilot.
Upon power up, the RAD shows the
Aircraft model, engine type and declares
instrument status: ‘Primary’ (if applicable).
Before each flight, confirm that it matches
your aircraft requirements.
RPM and MAP Display Basics
The upper half shows the RPM
(Revolutions per Minute) and the lower
half shows the MAP (Manifold
Pressure). Operations exceeding red line
cause the digital value to turn red.
Percent horsepower is displayed
digitally below and to the left of the
MAP arc.
Linear Bar Graph Display Basics
The Bar Graphs section contains nine
dedicated bar graphs with digital
display organized in a three by three
matrix. An example is shown here.
Pointers move up and down in response
to value changes and digital readouts
turn red when exceedances occur.
Note: functions displayed in this
example may differ from your EDM.
