  • Page 9: System Overview

    1 System Overview 1.1 System Description The Astronautics Flight Instrument (AFI) 4700 is a 5” by 7” Electronic Flight Instrument (EFI) designed to replace and improve upon the legacy electromechanical Attitude Director Indicator (ADI) and Horizontal Situation Indicator (HSI). Figure 1-1: System Description The AFI4700 is designed to interface with existing and/or retrofit attitude and heading units, navigation radios, GPS systems, etc.

  • Page 11: System Power Up

    1.2 System Power Up Initial power up displays color bars on the screen. After several seconds, the color bars are replaced by the flight application. During aircraft power up, the display may start faster than other systems, such as gyros, resulting in a time delay between power-up and the system receiving valid signals.

  • Page 12: System Operation

    1.3 System Operation The AFI4700 is an EFI whose design consolidates the ADI and HSI information with the addition of Radar Altitude, Traffic Collision and Avoidance System (TCAS), Global Positioning Satellite (GPS), and VHF Omnidirectional Range (VOR) map overlays, display of Weather Radar, external Terrain Awareness and Warning System (TAWS), and a Physical Slip/Skid Indicator.

  • Page 17: Navigating The Maintenance Menu

    1.3.3 Navigating the Maintenance Menu When the MAINT option is selected from the System Menu, additional information is displayed in the EFI STATUS page. MAINT is only selectable when the aircraft is on ground. This page contains a further sub-menu from which maintenance related functionality can be accessed.

  • Page 18: Crosslink

    1.3.6 Crosslink When more than one display is installed, the AFI4700s will communicate with each other via an RS-422 serial interface crosslink bus. In order to provide assurance of data accuracy, the EFIs constantly compares attitude, heading, localizer, glideslope, and radar altimeter information between the two displays.

Radar Altitude Indicates the current radar altitude from the radar altimeter. Decision Height Pilot selected decision height. Lateral Deviation Scale Four white dots indicate lateral deviation scale from the active navigation source input.

  • Page 21: Attitude Indicator

    2.2 Attitude Indicator The primary purpose of the ADI is to display aircraft attitude information and provide flight direction cues. This is achieved by presenting a graphical format resembling a conventional electromechanical ADI ball. The ADI uses colors and symbols to orient the aircraft with the inertial frame of reference.

  • Page 22: Extreme Attitude

    aircraft’s pitch along the pitch ladder and roll along the roll angle scale within the ADI. 2.2.1 Extreme Attitude Figure 2-3 Extreme Attitude Extreme attitude is defined as a roll greater than 65°, 30° pitch up, or 20° pitch down. Red chevrons are displayed at +/- 50° and +/- 70° pitch up and pitch down respectively.

  • Page 23: Figure 2-4: Ra & Dh

    HDG bug. The decision height is displayed in green text when the aircraft is above the selected DH. Figure 2-4: RA & DH The Radar Altimeter is tested from the test menu. In the test menu, depressing the RA button for three seconds activates a discrete output to the RA unit to initiate the test.

  • Page 24: Autopilot Annunciation

    2.4 Autopilot Annunciation Autopilot status and mode information is displayed in two dedicated regions on the top edge of the display. Autopilot and flight director information are only available if the AFI4700 is configured to support the aircraft’s flight director and autopilot. 2.4.1 Flight Director / Autopilot Modes Figure 2-6: Autopilot Modes Flight Director validity is shown in the top left corner as “FD”.

  • Page 26: Flight Director Display

    2.4.2 Flight Director Display Figure 2-7: FD Display The flight director display consists of two magenta bars overlaid on the ADI, which serve as a guide in orienting the aircraft flight path. The vertical bar is a heading cue (roll command), and the horizontal bar is a pitch cue.

  • Page 27: Approach Annunciation

    2.5 Approach Annunciation When an ILS approach is tuned by the selected NAV radio, the ADI changes functions to show annunciations relative to the approach. When performing an approach, tune NAV radio 1 and NAV radio 2 to the same approach ILS frequency. On final approach, select the runway course using the bezel course knob to ensure that the aircraft’s heading and runway course are the same.

  • Page 28: Lateral Deviation Indicator

    The glideslope deviation indicator is displayed to the right of the ADI when VOR is tuned to a valid ILS and is selected as the active NAV source. It appears as is shown in Figure 2-7 with four white dots and a green diamond.

  • Page 29: Expanded Localizer Mode

    2.5.3 Expanded Localizer Mode To support Category II approaches, an expanded localizer mode is displayed when the selected Decision Height is set to a value under 200 ft. The lateral deviation indicator is expanded, or zooms in, and the first dot to covers the entire lateral scale. To indicate this mode is different, bars are used in place of dots.

  • Page 30: Rising Runway

    2.5.5 Rising Runway Figure 2-12: Rising Runway The Rising Runway symbol provides an additional visual aid during landing. It consists of a virtual runway, which rises up from the very bottom of the ADI to the meet the aircraft reference symbol as the aircraft descends.

  • Page 31: Horizon Sync

    2.6 Horizon Sync When flying at a nose down attitude for extended periods, it becomes more difficult to determine slight changes in pitch attitude. Horizon Sync mode compensates for this by changing the current pitch attitude to zero and placing yellow tick marks where the pitch attitude used to be.
