Laminar Research Releases X-Plane 11.40 Beta 1

X Plane 11 2

Laminar Research has released X-Plane 11.40 beta 1. This is a major update and changes the experimental flight model. Included in the flight model changes are the handling of seaplanes, stalling, and prop wash improvements.

Austin has a full thorough explanation of the new experimental flight model available on Youtube. Along with the changes to the flight model, bug fixes such as incorrect metar QNH interpretation and some planes not changing the battery amperage when landing lights are turned on have been fixed.

The beta 1 update is available to Laminar Research customers and can be downloaded by running the 11.40 installer, checking the box to get betas, and completing the update. Steam users should see the beta 1 update available tomorrow.

You can read the full post on the Laminar Research blog page.
