##### **NavData**

- Improved handling of navdata for runways that do not exist in the sim. The resolution is now only done after all scenery layers are loaded, and only transitions will be removed rather than full procedures where possible.

- Fixed an issue where airports used as waypoints in instrument procedures contained a region code that prevented them from being loadable using the ICAO.

##### **Aircraft**

##### **Boeing 787-10 Dreamliner**

- Added the “autothrottle” aural alert when the autothrottle is disengaged.

- Added the “airspeed” aural alert when one of the autothrottle’s speed protection modes (MIN SPD or MAX SPD) is engaged.

- The CABIN ALTITUDE caution CAS message now appears when there are uncommanded increases in cabin altitude.

- Cabin altitude is now initialized to a sensible value when first spawning into a flight.

- The pressurization DUMP switch now functions properly.

- The ENGINE FAIL L/R CAS message now appears when FADEC detects an engine flameout.
