Synthetic Vision

Synthetic Vision within AvPlan EFB is designed to be an enhancement to situational awareness. It is not a certified system and therefore should never be relied upon for instrument flying.

Synthetic Vision brings a whole new level of terrain awareness. Terrain, obstacles and runways ahead of you are depicted in 3D.

With the addition of an external AHRS (Altitude and Heading Reference System) device, pitch and roll are also then accurately depicted. 

Synthetic Vision will still work without an AHRS, however no pitch or roll information will be depicted – only the straight-and-level view of the terrain ahead, based on your GPS position. You’ll see the no attitude input warning displayed while operating in this mode.

Synthetic Vision can be shown and hidden at any time by tapping the following icon: 

When turned on, the Synthetic Vision appears on the right half of the map page (one third if the flight plan is also visible).

Synthetic Vision Continued

Terrain around you is shaded according to the relative height:
 

When straight and level, you can use the Settings button in the lower right-hand corner to zero any or all of the three axes. It’s also a handy shortcut to download the relevant data.

*Early model iPads are only able to display the terrain. To display obstacles, runways, rivers/lakes/coastlines/etc, the minimum specs required are iPad Air or newer/iPad Mini 3 or newer.

Profile View

Tap the Profile View button to display a horizontal representation of terrain, obstacle and airspace. This view is an excellent tool to assist with planning vertical navigation and enhancing terrain or obstacle awareness during flight.

• Terrain less than 500 feet below planned altitude is displayed in red
• Terrain between 500 and 1500 feet below planned altitude is displayed in yellow
  Obstacles are also shown as red vertical lines (If Terrain Warnings is set to on – see Settings)

Airspace along your route is also depicted in the Flight Profile view. Controlled airspace appears as blue boxes, whereas PRD areas are depicted in red.

As with the Terrain overlay, the Flight Profile view operates in two distinct modes:
