Bluebird Simulations has released an extensive development update for its highly anticipated Boeing 757 add-on for Microsoft Flight Simulator, offering simmers a deep dive into the aircraft’s progress, systems realism, and a roadmap toward beta testing. The update, presented via a detailed video by project lead Shervin Ahooraei, highlights the team’s focus on engineering accuracy, operational depth, and visual fidelity.
Beta Testing and Release Timeline
In the 30-minute video posted on Bluebird’s Youtube channel, Sharvin touches on a wide range of topics regarding this project. Right now, while a public release date remains unconfirmed, Shervin disclosed that the project is advancing toward an early beta phase within the next few months, with over 60 beta testers—including the Bluebird internal team—set to evaluate the aircraft across three rigorous stages. A public release announcement is expected once the team is “two to six weeks out,” though Shervin emphasized it will not arrive in Q1 2024.
The initial release will focus on the 757-200 variant, featuring Rolls-Royce and Pratt & Whitney engine options, followed by a free update adding the stretched 757-300. A paid cargo expansion pack is also in development, promising enhanced features for freighter configurations while delivering free improvements to the base passenger model.
Systems Deep Dive: APU, Hydraulics, and Realism
The video showcased intricate system simulations, developed using actual Boeing schematic diagrams to replicate real-world logic. Key highlights include:
- APU Fuel and Electrical Systems: The APU dynamically draws fuel exclusively from the left tank, with detailed DC/AC power transfer logic. Beta testers observed real-time relay shifts between ground power and APU generators.
- Hydraulic Systems: Fully modeled hydraulic pressure networks link to flight controls, spoilers, and the Ram Air Turbine (RAT), which automatically deploys during dual-engine failure to power critical systems.
- Cabin Pressurization: A custom system simulates altitude-based pressure schedules, outflow valve operations, and negative pressure relief valves. Manual and automatic modes allow precise control, with cabin altitude warnings tied to physiological limits.
Flight Management and Autopilot: Built from Scratch
The team confirmed the autopilot and Flight Management Computer (FMC) are entirely custom-coded, bypassing default MSFS systems. Demonstrated features include:
- LNAV/VNAV Integration: Actively tuned for realism, with route discontinuities, altitude restrictions, and SID/STAR support.
- FMC Workflow: Full SimBrief integration, dual FMC independence, and detailed progress pages with fuel burn, wind data, and cabin altitude tracking.
- Auto Land: In development, promising a bespoke autoland experience post-release.
Visuals, Optimization, and Future Projects
The 757’s model and textures are “95% complete,” with a virtual cabin—featuring two exit door configurations—entering final texturing. Shervin used the landing gear and Ram Air Turbine (shown in Substance Painter renders) to highlight the high-resolution detail that the team is putting into this model of the 757. While they are definitely aiming toward high-fidelity visuals, performance optimization remains a priority.
Beyond the 757, Bluebird reaffirmed its Boeing 767 project remains in early stages, with accelerated progress expected once the 757’s codebase is finalized.
There’s no denying that Bluebird’s 757 promises a lot. The team’s transparency about the project’s development and progress is commendable, though such an ambitious endeavor also carries significant risks of falling short of the high expectations being set. While all signs currently point in the right direction, cautious optimism remains advisable—even as I personally lean toward optimism.
It’s important to remember that this is Bluebird Simulations’ first aircraft, with no prior track record to fall back on and everything to prove. With beta testing on the horizon, the MSFS community will undoubtedly keep a close eye on this project, eager to see whether this passion-driven effort can deliver on its bold vision. Stay tuned!
