- CSS News - January 11, 2026
- Welcome to another edition of the CSS Blog where we keep you up to date with our latest developments. We're happy to announce that as of today, the CSS 737-500 version 1.7.8 is now available in your CSS Launchers!
- This version features several fixes for the issues the community has discovered after our latest update. Namely, we've retuned the flight model so that the airplane takes off, flies and lands properly at any and all weights. A lot of tuning has been made to the FCC - VNAV and V/S modes should now work properly. We've also fixed an issue where pitot icing occurs even with pitot heat on, retuned flap extension and retraction speeds, fixed TCAS, N1 mode, KMOR being populated in POS INIT and reduced the intensity of the glareshield shake and wing flex.

Hopefully now your CSS 737 flights will go as smoothly as possible!
For our next update, we'll be focusing on adding more sim keybind/lvar compatibility and fixing Navigraph Navdata interpretation issues that lead to certain procedures being drawn incorrectly. Testing of the 737-300 and -400 is also underway, so expect more previews soon!
We've also added some new 737-500 liveries to the CSS Launcher:
- UTAir (RA-73046) (20K) (WL)
- Air North (C-FANF) (20K) (WL)
- Sierra Pacific (N709S) (20K) (WL)
- Sky Mali (TZ-SMA) (20K)
- Shirak Avia (EK-SHC) (20K)
All of these are notable for still being in active service today, in 2026!
Hope you enjoy the new update! Wishing you smooth landings with the CSS 737!
