WestJet’s Boeing 737-900 arrives as a polished freeware package built on the Project Open Sky model, with David Grindele refinements that enhance autopilot behavior, engine thrust curves, and overall handling for short- to medium-haul flying. Designed for FSX, it pairs an authentic stretched narrow-body profile with a modernized virtual cockpit and dependable performance.
This freeware release provides a detailed Boeing 737-900 in WestJet livery, featuring a complete implementation of the Project Open Sky aircraft model and additional modifications by developer David Grindele. It has been tested across several operating systems with no reported compatibility problems. The package includes all files needed for immediate installation, and it has been fully checked for potential security concerns.
The WestJet Boeing 737-900 showcases a twin-engine narrow-body configuration designed for efficient short- and medium-range operations. WestJet, as a Canadian carrier, utilizes the 737 family extensively for domestic and transborder flights. This adaptation retains the core geometry of the 737-900, offering a visually recognizable fuselage stretch along with modernized cockpit instrumentation.
Project Open Sky created the underlying flight model to ensure streamlined handling and accurate aerodynamic performance. These parameters replicate the actual operating profile of the 737-900, including climb capability, control surface responsiveness, and fuel management behavior. The modifications by David Grindele provide further refinements, such as optimized autopilot settings and fine-tuned engine thrust curves.

The original aircraft model and flight dynamics are courtesy of Project Open Sky. Developer David Grindele contributed all supplementary enhancements, ensuring up-to-date visual and operational elements. Together, they provide a comprehensive freeware rendition of the WestJet Boeing 737-900 that integrates seamlessly into FSX.

Installed into FSX Deluxe Edition, can't make 3D work which I don't use anyway. In 2D there is no VOR LOC Nav hold switch, so I can't get the aircraft to follow the flight plan. (Maybe there is another way to do it, but I can't figure it out.) Overall, this is an improved aircraft from the FSX base model.
wheres the 3d cockpit, 6 hours to download this just to find out its unusable F YOU. just add the stock 737 cockpit or make a new one
No gauges for the WestJet 737-900 . . please help.
I installed it in FSX Steam edition. Everything else works but there,s no gauges.
