For nearly two decades, the Flight1 Fokker 70/100 has remained one of the most beloved regional jet simulations for Microsoft Flight Simulator 2004 (FS9) and FSX. However, like many complex add-ons from the golden era of flight simulation, it required constant updates. Among the community, one phrase has become a rallying cry for troubleshooting and optimization: “FSX FS2004 Flight1 Fokker 70 100 Service Pack 2 20 Fixed.”
If you have struggled with gauge errors, autopilot disconnects, or performance stutters, you have likely been searching for this exact combination. This article will dissect what Service Pack 2 (version 2.20) fixes, how to install it correctly in both FSX and FS2004, and why this update is essential for keeping the Fokker flying in modern sim environments.
Even with SP2, FSX requires a small manual tweak:
FSX\SimObjects\Airplanes\F1Fokker100\panelpanel.cfg file.[Vcockpit01] and change gauge00 to reference the FSX-specific DLL (the installer usually does this, but verify).Many community posts ask: “Does SP2.20 fix the FDE crash on landing?” The answer is yes. Here is the definitive list:
| Issue in Base Pack | Status in v2.20 (Fixed) | | :--- | :--- | | Autothrottle overspeed on descend | ✅ Corrected | | LNAV banking beyond 30° | ✅ Limited to 25° standard | | EFIS baro setting in hPa | ✅ Now saves per flight | | Altitude alert horn silence | ✅ Mappable to key command | | CTD on FSX when loading saved flight | ✅ Resolved (memory leak patched) | | HSI VOR/LOC capture crossing angle | ✅ Expanded to 90° intercept |
fsx.cfg under [GRAPHICS] to prevent OOM errors.The sound package is distinct. The Rolls-Royce Tay engines have a specific whine and roar. The SP2 fixes included updates to the sound cone logic, ensuring the sound changed realistically as you moved the camera around the cockpit.
Even in 2025, the v2.20 fixed build runs exceptionally well. You will need to apply the “HighMemFix=1” in your fsx.cfg to avoid OOM (Out of Memory) errors on long hauls. The aircraft uses approximately 1.2GB of VAS at airports like EGLL or KLAX.

Final Score: 9/10 (For its era) If you are flying FS2004 for nostalgia or performance reasons on older hardware, the Flight1 Fokker 70/100 Service Pack 2 is an essential addition to your hangar. It represents the peak of what was possible in that simulator.
Flight1 / Digital Aviation Fokker 70-100 Service Pack 2 (SP2)
is the definitive update for the FSX and FS2004 versions of this advanced regional jet simulation. It addressed several long-standing system bugs and refined the aircraft's complex flight management systems. Fly Away Simulation Key Fixes and Features in SP2 (v2.20)
While version numbering sometimes varied between the installer and the internal DLL files (often cited as v2.20 or 2.0 fixed), the primary improvements include: FMC & LNAV/VNAV Stability fsx fs2004 flight1 fokker 70 100 service pack 2 20 fixed
: Refined tuning for approach speeds and more robust vertical navigation (VNAV) logic. FSX Integration
: Fixed issues with the aircraft appearing in FSX under Service Pack 2 and Acceleration environments. Autopilot Logic
: Corrected "hunting" behaviors in the autothrottle and flight mode transitions. Virtual Cockpit Fixes
: Although the "Early Adopters" version initially focused on 2D panels, SP2/v2.20 updates addressed compatibility for those using specific VC models and added fixes for rain effects. Performance Improvements
: General frame-rate optimizations for the complex gauge displays in both FS9 and FSX. Fly Away Simulation Legacy Support & Access Flight1 Library
: You can still find official registry and DLL repair tools at the Flight1 File Library
which are often necessary to get these older planes running on modern systems. Installer System : Modern installations usually require the Flight1 Agent
, which handles product authentication and library management for older titles. Flight1.com Comparison with "Project Fokker" It is common to confuse this with the freeware Project Fokker 70/100 v2
, which is a separate product for FS2004. That freeware version features its own maintenance animations (opening engine hoods) and specific panel updates but lacks the deep system depth of the Flight1/Digital Aviation release. Fly Away Simulation installation steps

: Fixes often target the Flight Warning System (FWS), resolving alert inhibition issues during specific flight phases. FSX Compatibility
: Modern updates for the FSX version often involve ensuring the 2D panels—highly praised for their detail—remain functional on newer operating systems, though DX10 preview mode often remains unsupported in "Early Adopter" versions. Navigation Updates
: Improved loading of MS default flight plans for both FS9 and FSX, alongside fixes for single DME tuning and Baro handling. Fly Away Simulation Technical Support and Resources Because these are older platforms, support from
