In a safe flight phase, note the current HSI format and navigation source.

Format availability

Compass / ARC / MAP

MAP not available for preview

Check which formats and controls actually appear. FSS lists Full Compass, ARC and MAP.

The HSI-button format-change instruction is highlighted in red, but the current Welcome page does not explain the highlighting. Check whether the control is available in your installed build.

Source and format

If preview information is missing, verify the selected format and source before changing receiver tuning.
