Primary Flight Display

The Primary Flight Display, or PFD, is a key component in the cockpit. It is the main source of information about attitude, airspeed, altiude, orientation and can combine many more sensors into a coherent picture. The EYEVIONICS PFD offers multiple modes, such as 3D Terrain & Topographic Imagery (with EYEVIONICS Aviator) or a distraction-free airliner mode (with EYEVIONICS Pro PFD).

PFD Configuration with the PFD Fold-Out

Any Panel with a PFD Portal will display a PFD Fold-Out at the top and bottom edges. This Fold-Out contains the configuration options for the EYEVIONICS PFD. It does not matter which PFD Fold-Out is used to change the PFD configuration.

Notable PFD Fold-Out Items

Altimeter Barometric Setting

To change the altimeter setting (referred to as Kollsmann window for analogue altimeters), open the PFD Fold-Out and tap BARO. A popup will open, offering you to change the altimeter setting.

This popup also allows toggling between inHg (inches of mercury) and hPa (hectopascal) units. Changing the altimeterunit here will change the altimeter unit in the entire EYEVIONICS user interface.

Appearance

PFD Style Pro PFD FEATURE

Cycle through available PFD styles.
Supported styles are:

Default

Default PFD style, supporting the 2D and 3D PFD modes.

Airliner

Only available with EYEVIONICS Pro PFD.
While selected, 3D Terrain and Inset Map are be disabled.
Get it here.

HSI Size

Cycle between available HSI sizes.
Useful for different flight phases (enroute vs approach) and for VFR and IFR. In IFR operations, the Minimal preset is often sufficient, allowing more space for other items on the PFD.

AHRS

Horizon Headings

Toggle heading numbers along the PFD horizon line on or off.
When enabled, headings are displayed in 10 degree incremenets just under the horizon.

Partial Horizon Pro PFD FEATURE

Limit the PFD horizon to the center portion of the PFD.
Only available when PFD → PFD Style is set to Airliner.

Symbology

Reference Symbol

Cycle between available aircraft reference symbols and associated flight director symbology in the PFD.
Available symbols are:

Inverted V

A golden, inverted V shape.

Wing

A shape resembling the profile of an aircraft.
Not available when PFD → PFD Style is set to Airliner.

Bars Pro PFD FEATURE

Symmetrical, L shaped bars.
Only available when PFD → PFD Style is set to Airliner.

Show Traffic AVIATOR FEATURE

Show or hide traffic icons in the PFD.
In addition, for traffic icons to be displayed, all these conditions must be met:

• PFD must be in 3D Mode. Enable with PFD → 3D Mode.
• Traffic must not be disabled in the MFD Fold-Out. Enable it with MFD → Traffic.

Flight Path Marker

Flight Path Marker

Toggle the Flight Path Marker icon on or off.

Marker Inertia

Cycle between Flight Path Marker inertia modes.
Available modes are:

Normal

Flight Path Marker has default sensitivity.
Recommended for most aircraft.

Low

Flight Path Marker reacts more quickly to acceleration of the aircraft along any axis.
Consider this setting for highly nimble aircraft, such as aerobatics airplanes.

High

Flight Path Marker reacts more slowly to acceleration of the aircraft along any axis.
Consider this setting for medium and heavy weight category aircraft, such as airliners.

Other

Pitch Limit Indicator

Toggle the Pitch Limit Indicator (PLI) on or off.
This indicator appears only when the bank angle is at or below 90° and when at least one of the following conditions is met:

• Landing gear is not fully retracted
• AoA is higher than half the AoA_crit
• Indicated airspeed is less than 110% of the stall speed for the current aircraft configuration
• EYEVIONICS detects that the aircraft is performing a takeoff

Suppress Stall

When enabled, stall warnings in the PFD are suppressed.
This setting is enabled automatically when EYEVIONICS detects a helicopter or VTOL aircraft.
The AoA indicator in the [SCSI](#secondary-control-surface-indicator-scsi) remains visible regardless of this setting and will turn red when the critical AoA is reached or exceeded.

PFD Modes

The EYEVIONICS PFD supports 3 modes:

1. 2D Mode (Default style)
2. 3D Mode (Default style, Aviator subscription required)
3. Airliner (Pro PFD add-on required)

2D PFD Mode

3D PFD Mode

Airliner PFD (Pro PFD)

Toggling Between PFD Modes

To toggle between the 2D and 3D mode, open the PFD Fold-Out and tap 3D Mode.
To enable the Airliner mode, open the PFD Fold-Out, scroll right and tap PFD Style.

3D Mode

When in 3D Mode, the PFD shows a terrain reference behind the PFD symbology. This terrain roughly matches what the pilot can see out the windshield of the aircraft in clear weather.

3D Mode Imagery

To cycle between Imagery types for the PFD 3D Terrain, tap on PFD → PFD Imagery.

3D Terrain Accuracy & Precision

3D Terrain reliability depends on two factors:

1. The accuracy of the 3D Terrain data
2. The Terrain Quality setting of the EYEVIONICS App (see this page)
3. The precision of altitude and position measurements

A horizontal resolution of ca. 30m can be assumed for 3D Terrain data. The precision of 3D Terrain symbology can be influenced by data of the following sensors, or the absence thereof:

• altimeter setting
• location data precision (GPS or similar)
• temperature measurement

As for the altitude measurement, it is up to the pilot to take the current altimeter setting into account when interpreting 3D Terrain symbology.

Non-Standard PFD Symbology

Secondary Control Surface Indicator (SCSI)

Since simulated flight cannot convey the feeling of the aircraft's acceleration along all of its axes, EYEVIONICS has developed the Secondary Control Surface Indicator to aid both in trimming the aircraft and to verify the state of secondary flight controls.

SCSI Location in PFD

The SCSI is located over the speed tape in the EYEVIONICS PFD.

SCSI Indications

SCSI Behaviour

Note that many aircraft with Fly-by-Wire systems change position of secondary control surfaces autonomously. This is reflected in the SCSI, usually by changing position of flap and slat bars.

The SCSI Trim Indicator will disappear a few seconds after trim was changed. When autopilot is engaged, the SCSI trim indicator will appear whenever the autopilot changes aircraft trim.

Airspace Situation Indicator

EYEVIONICS displays information about the current airspace at the top of the PFD. When inside multiple airspace boundaries, EYEVIONICS prioritises airspaces by the amount of restrictions they impose. Only the most restrictive airspace will be displayed here.

By tapping the airspace information, the airspace boundaries will be highlighted in 3D.

Altimeter Airspace Indications

The altimeter in the EYEVIONICS PFD can display airspace boundaries. Similar to the Airspace Situation Indicator, in case the aircraft is within multiple airspaces, the most restrictive airspace type is displayed. These indications can be disabled or enabled by tapping PFD → Airspace Limits.
