Flysimware has released version 0.4.1 of its Learjet 35A for Microsoft Flight Simulator 2024. The developer announced the update on November 14, 2026, in a post to its community, calling it “a massive update” that brings new features, system improvements and bug fixes.
The Learjet 35A is a twin-engine light business jet from the Learjet family, known for its speed and used by corporate, charter and air ambulance operators. Militaries have also flown the type, including the US Air Force, which operated it as the C-21A.
Among the headline changes, the aircraft moves to Asobo’s Modern Hydraulic System Version 2 and adopts the new native SU7 thrust reverser failure system. The Electronic Flight Bag has been completely redesigned and is described by the team as its most advanced EFB to date. It now includes live pneumatic and fuel system monitoring pages with zoom and pan controls.
On the avionics side, the update adds hot-swappable dual GTN 750 configurations for both the PMS50 and TDS versions. The livery tag system has also been expanded to nine options across all six aircraft variants.
Smaller changes include brighter exterior strobe, beacon and navigation lights. Flysimware also says its Learjet TrueSim technology now offers thrust reverser lockout protection for both mouse and hardware inputs. Fixes cover custom keyboard bindings that previously required the EFB to be opened first, and the thrust reverser hydraulic valve, which now operates correctly during hydraulic pump failures.
Because of the number of changes, the developer is asking the community to help beta test the update over the next 48 hours. Reports should be submitted in the PC support channel on its community Discord server and limited to the features and changes listed in the update. Flysimware says it is confident the update will go smoothly but notes that something could slip through.
Version 0.4.1 is available now through the Flysimware Product Manager. According to the developer, all other stores will follow once it is confident the update is ready for wider distribution. You can purchase the addon through the Contrail store for around 45€, or directly through the developer’s store for the same price.
