Engine type quick select
This function allows you to setup a basic engine monitoring system most suitable for your engine.
Once you have made your selection, go into the engine detail setup menu to change any settings
as required for your engine.
These functions assume that you are using default primary flight instruments in their standard
locations (primary flight instruments at the top half of the display).
You will be asked if you would like to program your selection on page 1 or page 2. The engine
layouts are slightly different for the two pages. The layout for page 2 is more compact as it is
intended for the IFR screen which needs more space for the primary flight instruments.
It is advisable to program your engine choice into both pages one or two or else you could
end up with a different engine type monitoring in each page.
The selected engine type is intended as a starting point from where you can customize the
settings to suit your engine and screen layout best.
Rotor craft setup menu
Should you want to use the Ultra with a helicopter or autogyro aircraft, simply change the rev
counter (RPM display) to rotor craft mode. You do this in the “Move screen items” function: Select
the rev counter and use “Select” to cycle through the display options until you have the opposing
needle rotor and engine RPM display.
This setup menu allows you to customize your display according to your aircrafts needs.
Rotor RPM low alarm:
Choose your low RPM limit for your rotor speed. This is entered as a percentage of your nominal
100% RPM (set below). Note: you still need to enable this alarm if you want to use it.
Rotor RPM high alarm:
Choose your maximum permissible rotor RPM as a percentage relative to your 100% setting.
Please note that you still have to enable this alarm if you want to use it.
Engine 100% RPM:
Enter the RPM value that corresponds to a 100% power setting. This is used to calculate the
correct 100% needle position for your engine RPM display.
