If you take a look at the Stratomaster Enigma/Voyager/ Odyssey. Each will charge an auxiliary battery. Your generator fails, your main battery fails and then you have 2 hours on backup. Very powerfull kit;
Primary Flight System Features
Primary flight system features:Altimeter: -700 to over 40.000 ft range, 1ft resolution at sea level.Airspeed: 16mph to 250mph range (other ranges on request).Vertical speed: +/-2000 ft/min analogue displays, +/-10.000 ft/min digital displays. TE mode available.AOA: 18 degrees nominal range (Range set during calibration flight).
Attitude
Connects to either low cost SP-4 AHRS or high performance SP-5 AHRS including aerobatic versions of SP-5.Magnetic heading (compass) using matchbox sized SP-2 for reliable remote installation.
Navigation
Built in 16 channel WAAS GPS, can use external GPS NMEA feed if required. Connection to standard NAV radios for ILS, Glide slope, VOR: RS232 serial, ARINC 429, +/-150mV analogue inputs.GPS only simulation of VOR navigation and ILS, Glide slope.GLS (GPS landing system) with highway in the sky 3D navigation to runway threshold.HITS (Highway in the sky) navigation system for GPS waypoints and routes.3D terrain look ahead with free World-wide terrain database.3D runways with live approach information without pilot interaction.Moving map navigation using raster or vector maps.Unrestricted ability for user to create and edit navigation data as well as raster and vector maps using free software applications.
Engine Monitoring
Single or dual engines, normally aspirated and turbine, fully flexible monitoring set up to cater for any type of engine.Uses standard, low cost RDAC remote engine monitoring modules for ease of installation as well as J1939 (CAN bus) based engine monitoring.EGT, CHT, Oil temp, Oil pressure, RPM, Coolant temp, fuel flow, fuel level(s), fuel pressure, voltage, current,... etc,etc.
Other Features
Automatic flight folio flight logging with export to PC based flight log viewer program. Logs up to 1000 flights with internal viewer."Black box" style logging of all flight data (primary flight, navigation, attitude, engine monitoring) to SD card with free PC based viewing application including export of flight path to Google Earth. Interface to COM and NAV radios for setting of frequencies from internal data base or rotary controls. 9 fully user customisable screens using free Odyssey Screen Designer and Simulator software. Layout your screens exactly the way you need them.
Other Features Continued
Voice prompts and warnings (if connected to suitable audio system), engine monitoring, navigation, primary flight etc. Voice prompts can be recorded to requirements using free PC application.Fully "Enigma" map and database compatible.Operates as single panel, dual or triple panel system with full, unrestricted functionality in each panel.Low power requirements, 1.5A at 12V at full backlight level.Dual backlights with independent power supplies.
Other Features continued
Connects to I/O extender for applications requiring large amount of additional monitoring and control such as remote control of Odyssey panel (using "hat switch" or similar on joystick). Easy and fast software upgradability using SD card. Free updates for life, high frequency of update cycles. Built in high capacity solid-state hard drive (no moving parts, no G-force restrictions). All navigation data and maps may reside oninternal drive.Ability to operate fully from external SD card slot including external booting of system (emergency operation in case of hard drive failureor during system test and configuration). User selectable units of operation, metres/feet, mph/knots/kmh, litres/gallons etc
Interfaces
RS232 port 1 - NAV/COM radio, FLARM, XAON XRX traffic systems, serial altitude encoder outputRS232 port 2 - NMEA autopilot output / external GPS inputARINC429 - 1 x TX, 3 x RX. Normal and high speed. TX->Autopilot messages, RX->NAV radios, traffic information systems (ARINC 735).USB Host - 2 x. Interconnect between multiple panels, MGL communications peripherals (Weather systems etc).USB Device - 1 x.Interconnect between multiple panels (slave connection).CAN (J1939). Automotive multidrop communications interface.Analogue - 4 x +/-150mV analogue differential inputs for connection to older generation NAV receivers (ILS, Glide slope and flags).Audio - high and low level outputs for audio voice prompts.Airtalk - 2 x multidrop communications bus (MGL propriety bus). Used to connect MGL attitude and compass sensors.Gillman altitude encoder output (standard parallel output bus).Input for Rotor speed sensor (Rotor craft usage only).GPS antenna input for active GPS antennas (SMA connector).
Power Supply
One input to 12V nominal supply. System operates from 6V to 28V.One input/output for optional rechargeable backup battery (recommended sealed lead acid, 2-5A/H capacity). Built in current limited charger.One secure 12V supply output for connection of vital equipment (AHRS, compass sensor, engine monitor(s)).
Sensors
Odyssey uses all the existing MGL & Floscan range of sensors. Fitting an RDAC module in the engine bay provides an interface for all engine mounted sensors, such as oil T & P, RPM, EGT, CHT, fuel flow etc. Rotax specific sensors are catered for, as are those fitted to other engines.
