The Model IT-04 Basic EFIS Trainer provides an introduction to a general aviation Electronic Flight Instruments System (EFIS). The EFIS used in Model IT-04 is a versatile unit that includes several features representing a modern EFIS display.

EFIS Features:

• External GPS Receiver with Jeppessen database
• External Remote Compass System
• H.S.I Resolver Interface
• ARINC 429 Interface (at least one transmit channel and two receive channels)
• Autopilot Interface
• GPS Interface
• ILS Interface
• NAV Interface
• Altitude Encoder Interface
• Emergency Power Battery
• Wiring harnesses must meet Mil Standard MIL-W-22759/16

Built-in Data Logging Capability:

At least 2 hours of cumulative data can be recorded at one second recording interval, and with a 10-second interval,    at least 20 hours data recording

AHRS Components

• Three solid-state gyrometers
• Three solid-state accelerometers
• Three solid-state magnetometers

Air Data System Components:

• Airspeed transducer
• Altitude transducer
• Angle of Attack transducer

Aircraft Heading information is obtained from 3 solid-state magnetometers. Additionally, a remote compass system input is provided.

EFIS Display includes the following:

• Horizon line, pitch and roll indicators
• 4 x EGT
• CDI/Glideslope Indicators
• Stabilized heading tape and digital readout
• Turn rate indicator
• Digital Altitude
• VSI
• Elevator trim indicator
• Winds aloft arrow
• Angle of attack (AOA) indicator
• Airspeed digital readout, and trend
• Bugs to mark a desired heading, airspeed, or altitude.
• Slip/skid ball
• Altimeter setting display
• Clock/timer
• Autopilot Status Indicator
• OAT
• G-Meter
• Voltmeter
• Timer

EEFIS includes H.S.I Display which shows course indication, course deviation, vertical guidance, ground track, ground speed, altitude, distance to waypoint, To/From indicator, Glideslope Indicator, and Glideslope flag.

H.S.I NAV Overlay includes text displays. The text displays (located at the top of the HSI Page) provide a variety of information comprising the course/OBS setting, the active frequency, the identifier for the tuned frequency, and the bearing to the active and secondary frequencies.

The GPS Overlay includes text displays to display a variety of information in text format. Displayed text to include the ground track (TRK), the course (CRS), ground speed (SPD), distance to next waypoint (DTW),and up to two bearing pointer selections.

EFIS Display Characteristics:

• Display Type: LCD, TFT (Thin Film Transistor)
• Backlight: at least 800 nits
• Size: 7.0” diagonal (178 mm)
• Resolution: 854 x 480 color pixels

EFIS Display Unit Inputs/Outputs Ports:

• One RS-232 bidirectional PC communication (for EFIS set up via a PC or laptop)
• One RS-232 data inputs (for GPS)
• One RS-232 serial encoder output (for altitude encoding)
• One Multi-drop Avionics Bus (for additional displays)
• One Analog Audio Alarm (for angle of attack alarm)

Power: 110V AC or 220V AC at 60/50 Hz, single phase
