pc12.efs

The EFS 40/50 Electronic Flight Instrument System for the Pilatus PC12 aircraft. The Bendix/King EFS 50 is a full-function 5-inch EFIS. The EADI, EHSI and MFD displays are all fully interchangeable ED 551A's. The typical configuration for the Pilatus PC12 consists of 2 Display Units (DU), One Symbol Generator (SG) and one EFIS Control Panel (ECP). The Pilot operates the EFS 40/50 Display Units through an EFIS Control Panel. Available as a separate unit or integrated with the EFS 40 EHSI. |

COMPOSITE ENROUTE - COMPOSITE APPROACH

Composite Enroute Mode

Composite Modes are reversionary displays typically used in the event of a hardware
outage or when standard presentations are not available. The differences between the
composite and standard Enroute formats include:

Note: For this version of the panel, we use a combination enroute and approach format view

- Navigation mode is annunciated on the side of the screen
- The selected course and heading are displayed
- Distance is displayed in lower left corner (not implemented in this version)
- Heading tape appears on the horizon
- The lateral deviation scale display is shown as a white unfilled diamond (zero index) flanked by four white unfilled circles.
- No rising runway is displayed
- Orange heading bug similar to that used on the EHSI is shown on the heading tape.
- An unfilled colored course indicator appears on the heading tape
- NAV system and source are displayed with annunciation colors following the convections of the EHSI.

TEST - MAINTENANCE AND CONFIGURATION

This option is not implemented in this version of the panel.

THE PROPER ATTITUDE

Precision Approach Mode

For EADI applications, there are two normal, two composite and three ancillary formats that are available. The normal formats, Enroute and Precision Approach, depict the typical displays that would be seen during Flight. Information normally shown in Enroute Format (as seen above) includes attitude, heading, flight director command bars, autopilot flight director mode annunciation, fast slow indicator, rate of turn and inclinometer along with a number of variants. The Precision Approach format generally depicts most of the same information as found in the Enroute mode with the following differences.

- A deviation scale displays the LOC or MLS lateral deviation
- A vertical scale is used for ILS or MLS glidepath information
- The rising runway symbol appears if a LOC frequency or MLS has been selected
- The runway symbol moves horizontally to indicate LOC or MLS horizontal deviation
- LOC or MLS mode annunciation is displayed on the lower left side of the screen
- The glideslope scale and pointer appear if a LOC frequency or MLS has been selected
- Selected DH and symbol are shown in upper left corner of display
- Radar Altitude above the ground is shown in the upper right corner of the display

THE TOTAL PICTURE - EHSI

In addition to this, all comparators are enabled, and a full array of variants similar to that
of the Enroute Mode shown above is available.
