(Obsolete) EFIS "ULTRA"

MGL Stratomaster ULTRA Description

  • The Stratomaster Ultra Horizon XL is a digital multifunction instrument designed for use in ultralight, microlight, experimental and homebuilt aircraft as well as any aircraft that permit use of such instrumentation under general or special operating permits.
  • The Ultra is designed around a transflective 5.7” monochrome display panel with a white LED backlight. The monochrome panel is suited for operation in direct sunlight. The panel does not need to be shaded and is capable of producing a clearly readable image even in very bright light conditions, with the light falling directly onto the panel.
  • Weight less than 1Kg (without probes).
  • The Ultra Horizon XL replaces the following previous product releases: "L" "X" "RL" "HL" and "HX".
  • The Ultra Horizon XL can be connected to the following sensor sources:
    • SP-6 three axis, tilt compensated magnetic compass.
    • SP-7 horizon / turn&bank sensor.

Ultra "HXL"

MGL Stratomaster ULTRA HXL

  • The ULTRA "HXL" is universal. It can be configured for any type of engine, like 2-stroke Rotax 447, 503, 582, 614, Hirth, 2SI etc..
    It supports as well 4-stroke Rotax 912/914, and larger 4-stroke engines as Hirth, Jabiru, Lycoming and Continental.
    It can also be used for converted automobile engines, air or liquid cooled.
  • Engine monitoring is entirely programmable.
  • The Ultra Horizon XL is a fully user configurable panel that can be used as primary flight instrumentation display, engine monitor or both.
  • The Ultra provides two display pages, each page can be configured by the user, choosing from a selection of more than 50 instruments and display items.
  • Each item on the screen may be placed where the user wants it and most instruments provide several different display options. For example you can choose between analog altimeter and a tape based altimeter amongst other choices.
  • Customization can be done on the instrument itself, or with a free simulator program on PC.

MGL Stratomaster RDAC

  • RDAC = Remote Data Aquisition Computer)
  • Some MGL Avionics instruments (E2, Extreme, ULTRA, ENIGMA) use a remote data acquisition module for engine data acquisition.
  • This architecture makes the installation easy, since there is no need to extend sender cablezs all the way to the cockpit.
  • The RDAC is installed close to the engine, and connects to the display system with a shielded two wires cable.
  • There are four versions of RDAC:
    RDAC V_D 4 CHT/EGT channels, no manifold pressure sender
    RDAC X_B 12 CHT/EGT channels, no manifold pressure sender
    RDAC X_D 12 CHT/EGT channels, with manifold pressure sender
    RDAC X_E 12 CHT/EGT channels, with manifold pressure sender, OEM version with ASCII output
  • Download the installation manual RDAC_V : Install manual RDAC_V (.PDF)
  • Download the installation manual RDAC_X : Install manual RDAC_X (.PDF)
  • You wish to integrate a RDAC to your aplication? Download the RDAC_X OEM protocol manual: RDACX_OEM.pdf
  • The RDAC is supplied with a 3 meters cable.
  • Four or twelve channel thermocouple amplifier, high resolution chopper stabilized system with full cold junction compensation and bow voltage correction to laboratory standards.
  • The thermocouple inputs can accept K-type or J-type thermocouples.
  • Oil and Water temperature NTC input compatible with most oil temperature senders and the MGL water temperature sender.
  • Also accepts MGL precision semiconductor senders for water and oil temperature.
  • optional 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.
  • Oil pressure sender input. 50 to 1000 ohms. Accepts most commercial oil pressure senders including those from VDO. Rotax uses a 200 ohm sender
  • TWO Fuel level sender input with extensive calibration functions provided to allow direct readout of fuel quantity corrected for tank shape and sender tolerances.
  • Fuel flow sender input. Can be used with most commercial liquid flow senders. Flow measurement without sender on injection systems by measurement of injcetor opening time (i.e. Hirth engines).
  • Universal rev counter input. Can be used on a wide variety of engines using a variety of interface methods.
