Synthetic View / Artificial Horizon

Go to View → Synthetic View to open the real time synthetic 3D vision.

The 3D view represents the aircraft surroundings with data provided by the Digital

Elevation Model and the landing point location.

Additionally to the 3D environment information, the Synthetic View provides a lot of useful

real time information through a HUD, such as speed, altitude, course or variometer.

The HUD also represents the autopilot commanded values in yellow color and the

commanded attitude in purple like a flight director. The variometer on the left side

represents the instant variometer measure with a filled triangle and the filtered value with

an empty one.

On the bottom of the display information about unit being used to present the data is

given.

Information about the visualisation mode and flight mode is represented on the top left

corner and the distance to the landing is placed on the right.

Terrain elevation is generated using a Digital Elevation Model (DEM for

short) incorporated into U-See.

Default DEM used in U-See has global coverage but, in exchange, its

accuracy at some points may be lacking. Errors as high as 150 m. can

exist.

. Its

accuracy is not enough to keep the plane from running into ground. This view is

supplied only as a way of improving situational awareness of the operator. Not as a tool

to pilot the plane.

This warning still applies if high detail DEM is loaded instead of U-See default: DEMs

usually do NOT include obstacles (as buildings and antennas) and terrain may have

changed since the DEM preparation date by human development.
