EFIS

The Super27 package introduces the Rockwell Collins EFIS-86C Electronic Flight Instrument System as an optional replacement for the analog ADI and HSI. It also includes the APS-85 autopilot system and is linked to the dual GNS-XLS flight management computer.

Setup

You can enable the EFIS suite through the clipboard on the options page. We suggest to do that on ground and restart the flight after switching.

EADI Display

The EADI shows the familiar attitude display with lateral and vertical computed steering signals needed to give the commands to intercept and maintain a desired flight path. Also presented are the FCS mode annunciation, autopilot engage status, attitude comparator warnings and decision height set. Other parameters are displayed as a function of pilot selection or operational modes. The EADI provides the following display information:

• Attitude display and sensor annunciation

• Attitude comparator warnings

• Flight director commands and FCS mode annunciation

• Autopilot/yaw damper engage status

• Primary vertical deviation from GS, FGS (LNAV controlled glideslope) or VNAV sensors

• Second course related vertical deviation from FGS

• Lateral deviation from VOR, LOC, LNAV sensors

• LOC/GS deviation displayed only when a LOC frequency is tuned and not in backcourse mode.

• LNAV APPR mode that allows a compatible LNAV to control pitch and bank commands during approach.

• CATII excessive deviation and comparator warning for ILS, indicated airspeed, and radio altitude

• Radio altitude is displayed only when the radio altimeter system is within range.

• Decision height set and DH annunciation

• Air data information (IAS, airspeed trend, reference airspeed bugs, MACH)

• Speed deviation from a fast slow system.

• Marker beacon

• Flags

EHSI Display

The EHSI brings together numerous displays to show a map-like presentation of the aircraft's horizontal navigation situation. The EHSI shows aircraft heading and aircraft displacement relative to VOR radials, localizer, and glideslope beams.

The EHSI can display three formats that are selected with the HSI MODE button on the Display Control Panel. These are the full compass rose, sector, and sector with map formats. The EHSI provides the following display information:

Rose, Sector, or Sector With Map Formats

• Aircraft symbol

• Heading display

• Selected heading cursor

• Active selected arrow pointer and lateral deviation bar

• Active selected course digital display

• Active selected course navigation sensor annunciation

• Active selected course to/from arrow (rose format)

• Active selected TO/FR annunciation (sector and sector with map formats)

• Second course arrow and course deviation

• Second course navigation sensor annunciation

• Vertical deviation display

• Bearing pointer display and sensor annunciation

• Distance to VOR/DME or waypoint

• Waypoint or DME identifier and waypoint alert

• DME hold annunciation

• Navigation data display (GS/TTG/ET, or TAS)

• Wind direction/speed

• Flags and comparator warnings

Sector Format

• Expanded compass segment across the top of the display

• Aircraft symbol relocated at bottom center of display

• Second course VOR/DME/waypoint symbol with identifier

• Range is selected with the DH/RNG knob on the Display Control Panel

Sector With Map Format

• Also uses the expanded compass segment

• Places VOR and/or waypoint symbols

• DME ident is shown next to the VOR/DME symbols

• Selected course lines are drawn through the symbols

• Waypoint strings are shown with their identifiers next to the symbol and with the symbols onnected by desired track lines.

Display Control Panel

The controls on the display control panel select the information that shows on the EADI and EHSI displays. For the EHSI the DCP selects the display format and various operating functions. For the EADI, the DCP controls set the decision height.

HSI MODE

Sequentially push the HSI MODE button to step through the EHSI display format selections:

• ROSE: The EHSI full compas rose format is displayed in a manner similar to a conventional HSI.

• SECTOR: This format shows and expanded compass segment across the top of the display with the airplane symbol centered at the bottom. Information similar to that presented in the full compass rose mode is shown in an enlarged format.

• SECTOR WITH MAP: This format also uses the expanded compass format but places navaid and/or waypoint symbols for both active selected course and preset second course in proper rho-theta position with respect to the airplane symbol and selected range.

CRS (Course)

Sequentially push the CRS button to step through the selections of navigation sensors to be connected to the EHSI active selected course arrow and lateral deviation bar (solid double bar course arrow).

The possible selections are VOR/LOC, FMS and ADF.

Holding the CRS button for langer than ½ second causes the course deletion to cycle directly to the primary VOR/LOC system.

2ND CRS (Second Course)

Sequentially push the 2ND CRS button to allow information from a second navigation sensor to be displayed on the EHSI.

The second course arrow is displayed in cyan as a solid single bar course arrow.

BRG (Bearing)

Sequentially push the BRG button to step through the selections for number 1 (single arrow) and number 2 (double arrow) bearing pointers.

The possible selections and their sequence of selection are VOR1, VOR2, ADF1, ADF2, FMS1, FMS2. VOR selections are removed from the sequence if the corresponding localizer is tuned.

Holding the BRG button for longer than ½ second causes the bearing selection to cycle directly to the "off" state.

DH/RNG (Decision Height/Range)

The dual function DH/RNG knob sets the decision height shown on the EADI and selects the range on the EHSI when in the sector formats.

DH Position: The decision height altitude apperas on the EADI, and rotating the knob changes the DH setting in 10 foot steps.

RANGE Position: Rotating the knob selects range on the EHSI when either of the sector formats is being displayed. A dashed cyan range arc is shown at midrange and one-half of the full scale range is displayed at the right end of the range arc. Available full scale ranges are 5, 10, 25, 50, 100, 200, 300 and 600 nm.

DIM

Rotate the DIM knobs to change the intensity of the EADI or EHSI.

Course Heading Panel

The CHP-85C panel has independent course and NAV data controls for both sides (pilot & copilot) of the FIS system and selected heading controls (HDG knob and PUSH SYNC button) that control both sides of the system at the same time.

PUSH CRS DIRECT

Push and release the PUSH CRS DIRECT button to automatically center the deviation bar with the course arrow pointing directly to the station.

CRS (Course Select)

Turn the CRS 1 knob (pilot's side) or the CRS 2 knob (copilot's side) to set active and second course arrows shown on the respective EHSI.

PUSH HDG SYNC

Push and release the PUSH HDG SYNC button to set the heading cursor to the aircraft's current heading shown at the lubber line on EHSI.

HDG

Turn the HDG knob to set the position of the magenta selected heading cursors on both the pilot and copilot EHSI.

NAV DTA (Navigation Data)

Push the NAV DTA button to select ET (elapsed time), GS (ground speed), TTG (time-to-go), or TAS (true airspeed) to show in the upper right corner of the EHSI. Each push of the NAV DTA button selects the next data type in the sequential order as just presented.

ET (Elapsed Timer)

Push the ET button to operate the elapsed timer functions on the NAV data display. The ET button on the left side controls the timer on the pilot's EHSI and vice versa. The timer has three modes: start, stop and reset. Each time the ET button is pushed, the timer advances to the next mode in the sequence. After starting the timer TTG, GSP or TAS may be selected with the NAV DATA button and the timer will continue to count.
