Bluebird Simulations released the current feature list of its upcoming Boeing 757 for Microsoft Flight Simulator 2020 and MSFS 2024.
The list, which was shared on the developer’s Discord server, is only partial, as more items will be added at release, and it’s already massive. It was provided to give us a better idea of the depth of the simulation.
The developer also mentions that a comprehensive failure suite will be added after release, but the systems are built with failures in mind.
It’s worth reminding that the 757 is on track for a Q3 2026 release, and is built natively for MSFS 2020, but compatible with MSFS 2024. A native MSFS 2024 version will be provided after release at no additional cost.
Without further ado, I leave you with the list. You’d better find a comfortable chair and a cup of coffee.
Systems:
21 – Air Conditioning
● Air Condition Packs, Pack Valves, and Trim Air system fully coded with associated circuit breaker logic
modeled. Air Condition Packs have integrated pack controllers that allow for low/high automatic flow.
Standby controllers are also simulated and functional for malfunctioning auto controllers.

Cabin has a natural tendency toward ambient temperature or worse depending on passenger count, etc.
● Many factors influence cabin temperature from door and window combinations, to wind and weather, to pack
effectiveness and pack quantity.
● Air conditioning will feel like an actual component of flight simulation for airline operations. It’s not a
byproduct of just turning the packs on, but managing an actual aircraft cabin.

like uncomfortable cabin temps, cabin secure announcements or response to two sets of cabin chimes
(cleared for departure signal from flight deck), they might even remind you to turn on the fasten seat belt sign if
descending in range and cabin securing is being completed. Emergencies use cabin alert calls from flight
attendants for events including passenger oxygen deployment and cabin altitude warnings/depressurization
(with more to come later).

PERF calculation in CDU which may cause a limitation of Assumed Temp Derated Takeoff calculations
(because CDU will now have a higher OAT than reported METAR/ATIS source weather. This is a mostly rare, but
fully simulated, corner case scenario in the B757.
