The Ultra Horizon XL combines all the functions of all the previous Ultra models into one sleek looking instrument. It has 2 easy customizable display screens, which can be swapped at a push of a button. One screen for example can be made up to show your primary flight instruments while the other screen can be made up to show the attitude indicator and engine monitoring information. IT IS UP TO YOU to decide how it must look.

In addition a free PC software package can be used to easy customise your Ultra in the comfort of your armchair, and then later at a click of a button, download the configuration you have just created into the Ultra.

You can design your own screen layouts using the Ultra Horizon XL or you can design your screens using our PC based Ultra design and simulation program which you can download right here for free:

Ultra Horizon XL screen designer and simulation

(Requires PC,  Windows 95,98,ME,NT,2000,XP. For simulation, 2.0Ghz PC minimum required)

This program allows you to simulate the actual Ultra instrument with all its functions. In addition you can use it to design your own screen layouts and configure your instrument in detail. When you are ready, you can simply download your design to the real instrument. You can also upload designs from your instrument to your PC and store these for use with other Ultras, you can create a whole personalized library of screen layouts and instrument setups.

This program is also used to update your Ultra to the latest firmware release so you can be sure you allways have the latest software and features installed.

Firmware version of this release: 260607X. This firmaware code is displayed at the bottom of your startup screen.

We recommend that all current Ultra Horizon XL instruments be upgraded to this firmware version to include important  updates.

You can perform these updates yourself if you own a PC to airtalk cable (optional item available from your dealer). This cable is also included with the flight log download device.

If you do not have this cable, please contact your dealer to perform the update for you.

• 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”.

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 consist 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.

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:

• 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.

• 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.

• 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:

• Date (DD/MM) of take-off

• Take-off time.

• Flight time. Displayed in either hours and minutes or hours and fraction of hours depending on setup.

• Highest altitude reached (In ft or meters depending on setup)

• Maximum airspeed obtained. Displayed airspeed depends on whether ASI or TAS is selected. (Displayed in kilometers, miles or knots depending on setup).

• Hobbs meter reading at end of flight/lesson (Displayed in either hours and minutes or hours and fraction of hours depending on setup)

• Pilot number
