•
Universal rev counter input. Can be used on a wide variety of engines using a variety of
interface methods.
•
Fuel flow sender input. Can be used with most commercial liquid flow senders.
Calibration via provided menu functions.
•
Oil pressure sender input. Accepts most commercial oil pressure senders including those
from VDO.
•
Fuel level sender input with extensive calibration functions provided to allow direct
readout of fuel quantity corrected for tank shape and sender tolerances.
•
LM335 sensor based temperature sender to indicate ice warning. The sender is normally
fitted to the outside of a carburetor, in close proximity to the throttle slider or valve or in
the intake airflow.
The EMS included with the Ultra “H” provides for a wide variety of engines and the display
unit can be configured in many different ways as outlined under the “Device setup menu”.
AHRS and compass functions
Available funcions in this category depend on the capabilities of the sensor package
connected. The following list shows functions available with the SP-3hc package.
•
Bank/Pitch attitude display. This display resembles the artificial horizon as found on typical
IFR panels. The attitude display is not restricted to a range of bank or pitch and is thus
fully aerobatics capable.
•
Bank&Turn display. This consits of Rate 1 markers (2 minute standard rate turn at 20
degrees bank) and a traditional “ball slip” display.
•
Compass or gyro compass heading. This depends on the abilities of the connected
package.
Flight log
Perhaps one of the most useful features of the Stratomaster Ultra instrument is the ability to
record a flight log.
You can setup your Stratomaster Ultra to record a log entry in one of the following ways:
1. Automatic flight log normal aircraft. This will automatically detect the start of a flight and
end of a flight. The unit uses engine revs in combination with airspeed to detect a flight.
This is the way most pilots prefer to operate the Stratomaster Ultra.
2. Automatic flight log rotor craft. This operates similar to above but air speed is not taken
into account. Instead, rotor speed above 70% of the 100% setting is used to mark
possible start of a flight. If you select the split rotor/engine RPM display this mode is
automatically selected.
3. Manual flight log. In this case the pilot manually starts a flight and ends it. This mode is
used mainly if no rev counter input to the instrument is available.
The Stratomaster Ultra will log all flights of longer than one minute. Any flights with less than one
minute accumulated time are not stored in the log.
The Stratomaster Ultra will store the last 200 flights in the log.
At the end of a flight, the pilot number selected in the main menu will be written to the log entry
for the flight. This can be used to log airtime of several pilots, for example with aircraft sharing
schemes. The log can be viewed at any time. Please also note that the log may be downloaded
to a PC using a direct cable connection or key-ring download device (optional extras).
The following information pertaining to a flight will be logged:
