Fsx Fs2004 Flight1 Fokker 70 100 Service Pack 2 20 Fixed

The Flight1 and Digital Aviation Fokker 70/100 simulation remains a landmark "study-level" add-on for Microsoft Flight Simulator 2004 (FS9) and FSX. While newer versions for modern platforms like MSFS 2020/2024 are currently in development by Just Flight, the original Flight1 release was renowned for its unprecedented depth in systems simulation. Core Simulation Features

Originally released as an "Early Adopters" version, the package focused on high-fidelity aircraft and flight modeling over visual fluff, initially shipping only with a 2D panel to prioritize the complex systems.

AFCAS Autopilot: Features a sophisticated autopilot system that supports CATIII autolandings in crosswinds up to 30 knots and a guided takeoff mode with automatic rudder input during engine failure.

FMC Simulation: Includes a high-end Honeywell FMS (software version 2A) with SID/STAR database support and both strategic and tactical modes.

System Depth: The simulation covers detailed electrical bus systems, bleed air and hydraulic logic, realistic APU starting, and a weather radar with ground reflection.

Flight Dynamics: The FDE (Flight Dynamics Engine) is tuned to match real-world performance data to within 2–5%, specifically modeling the Rolls-Royce Tay 620 (F70) and Tay 650 (F100) engines. Service Pack 1 Improvements

Service Pack 1 was a critical update that refined the simulation and fixed various community-reported bugs:

FMC and Navigation: Fixed approach speed display bugs in the FMC/PFD and improved default flight plan path finding for different language versions of FS9 and FSX.

System Tweaks: Added the MAINT4 page, fixed TCAS bugs, and allowed the transponder to be switched to an IAS-independent Mode C.

Operational Quality of Life: Enhanced the autobrake behavior, allowed the Baro to handle inHg, and enabled the FMC to handle weight in pounds (lbs).

Flight Model: Refined the FDX (Flight Dynamics) for better flare and rudder effectiveness. Evolution to Modern Standards

While the original Flight1/Digital Aviation project famously lacked a virtual cockpit (VC), many users turned to freeware alternatives like Project Fokker v2 for visual upgrades in FS2004. Today, Just Flight is developing a new "Professional" series for MSFS 2020 and 2024, which will finally include full 3D modeling, 4K/8K textures, and an integrated EFB to meet contemporary simulation standards.

Review: The Flight1 Fokker 70 & 100 Service Pack 2 (SP2) – The "Final Fix" for a Classic Airliner

Product: Flight1 Fokker 70 & 100 (Service Pack 2 / Fixed Version) Developer: Digital Aviation (Published by Flight1) Compatibility: Microsoft Flight Simulator 2004 (FS9) & FSX (FSX:SE compatible via migration) Topic Focus: The stability and functionality fixes introduced in Service Pack 2.

Final Verdict: Is the Flight1 Fokker 70/100 SP2 v2.20 Worth It in 2026?

Absolutely. Even when compared to modern MSFS 2020 add-ons, the systems depth of this Fokker remains impressive. For simmers still flying FSX or FS2004 (and there are thousands who prefer the stability and classic missions), the “fsx fs2004 flight1 fokker 70 100 service pack 2 20 fixed” represents the peak of that era.

You get a meticulously modeled FMS, accurate fuel planning, a challenging but rewarding manual flight envelope, and the satisfaction of taming a regional jet that feels alive. Since the release of v2.20, the autopilot no longer hunts, the gauges no longer flicker, and the CTDs have ceased.

In short, Service Pack 2 version 2.20 is not just a patch—it is the completion of the Flight1 Fokker 70/100. It is the “fixed” jet that the original release always promised to be.

4. Known “20 Fixed” – What It Solves

Problem:
When selecting a heading of 020°, the AP would either not turn or would stop at 020° incorrectly when turning from >200°.

Solution (manual):
In F1F70.gau (or the F1F70.dll for FSX), the heading error wrap-around was miscalculated. The fixed version adds a modulo 360 check.

If you cannot find the official fix:

Use the HDG SEL button twice after setting heading.
Or set heading 021° instead of 020° as a workaround.

User Testimonials: “Finally, a Working Fokker”

"I flew the real Fokker 70 for KLM. The Flight1 model was great, but the v1 autopilot was a nightmare. Service Pack 2.20 fixed the pitch instability. It finally feels real." – Captain van der Berg (Avsim User)

"My FSX kept crashing after 45 minutes in the Fokker 100. I downloaded the SP2 v2.20 installer, reinstalled clean, and now I can fly JFK-BOS without a single stutter. The '20 fixed' is no joke." – SimmerJake (YouTube)
