EYEVIONICS App

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.

EYEVIONICS App PFD Fold-Out

HINT You can scroll through the PFD Fold-Out by swiping sideways.

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.

  • AoA is higher than half the AoAcrit
  • 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.

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.

WARNING 3D Terrain for Reference Only

3D Terrain is not a replacement for visual contact with the ground. Avoid relying oly on 3D Terrain when flying in Instrument Meteorological Conditions (IMC) or low visibility.

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.

NOTE Altimeter Setting

The closer the altimeter setting is to the actual environmental conditions, the more precise the 3D Terrain indication.

Non-Standard PFD Symbology

Most of the indications in the EYEVIONICS PFD are aligned with the standard symbology in the aviation industry. The following describes those indicators that differ.

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

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

SCSI Indications

SCSI Indications
SCSI Indications
  1. Leading Edge Flaps ("Slats")
  2. Flap Handle Position in Percent (25% in this image)
  3. Trailing Edge Flaps
  4. Spoilers/Speed Brakes
  5. Angle of Attack
  6. Trim Indications (see image below)
The Angle of Attack indicator (5) will turn red when approaching critical AoA.
SCSI Trim Indications
SCSI Trim Indications
  1. Elevator Trim
  2. Aileron Trim
  3. Rudder Trim
White bars show the current trim state. Black bars show neutral trim state (center cross) and maximum trim (outer bars). In this image, rudder and aileron trim are neutral, elevator trim is about 25% aft (nose high).

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.

EYEVIONICS Airspace Situation Indicator

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

AVIATOR FEATURE This feature requires EYEVIONICS Aviator. Get it here.

EYEVIONICS Airspace Highlighting

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.

Example: Altimeter Airspace Indications
In this case, the aircraft is descending through 16,500ft MSL, where it can expect to cross from a glider area (brown yellow) into a restricted (orange) airspace.

Even though the glider area in this example extends from FL115 up to FL195 and the restricted airspace extends only up to FL165, the restricted airspace has a higher priority and therefore, it is displayed over the glider area.
