The iFly 737NG for FSX remains one of the most iconic "classic" add-ons in the flight simulation world. Even years after its release, it holds a special place for pilots who appreciate deep systems modeling and a variety of airframe options.
While newer platforms like MSFS 2020 dominate the headlines, the iFly 737 for FSX still runs hot for enthusiasts who prefer the stable, mature environment of Flight Simulator X.
Here is a deep dive into why this bird is still a must-have for your virtual hangar. A Legacy of High-Fidelity Simulation
When iFly released their 737NG series for FSX, it was a game-changer. It wasn't just a visual model; it was a comprehensive simulation of the Boeing 737 Next Generation.
Full FMC Integration: The Flight Management Computer is the heart of the plane. iFly modeled VNAV, LNAV, and RNP approaches with precision.
Varied Fleet: The pack includes the -600, -700, -800, and -900 variants, along with BBJ (Boeing Business Jet) versions.
Interactive Cockpit: Nearly every switch, knob, and lever in the 2D and 3D cockpits is functional and linked to the aircraft’s logic. Key Features That Keep It Relevant
Even compared to modern standards, the iFly 737 packs features that make it a "hot" item for FSX users:
Engine Variants: Choose between different CFM56-7B engine ratings, affecting your takeoff and climb performance.
Custom Sounds: The roaring sound set provides an immersive experience from startup to shutdown.
Configuration Tool: An external application allows you to set up fuel, passengers, and specific airline options (like eyebrow windows or winglets) before you even launch FSX.
HUD Options: The Heads-Up Guidance System (HGS) is available for those tricky Category III landings in low visibility. Why Pilots Still Choose FSX and iFly
You might wonder why users are still searching for this specific combo. It often comes down to performance and familiarity.
Many simmers have invested thousands of dollars in FSX-compatible hardware and scenery. For them, the iFly 737 is the perfect centerpiece. It is less resource-heavy than some of its competitors, allowing for "hot" performance (high frame rates) even on mid-range PCs.
The flight dynamics are also a high point. The iFly 737 captures the "heavy" feel of the Boeing controls, requiring active pilot input during manual flight, especially during the flare. Tips for Getting the Most Out of the iFly 737
Update Your AIRAC: Use a service like Navigraph to keep your FMC database current with real-world waypoints.
Use the "Cold and Dark" State: To truly appreciate the systems, start with a powered-down cockpit and follow the real-world checklists.
Check the Liveries: There is a massive library of free community-made liveries available online, covering almost every airline that ever flew the NG.
📍 The iFly 737NG proves that high-quality system depth never goes out of style. Whether you are flying a short hop from London to Amsterdam or a transcontinental BBJ trek, this aircraft delivers a professional-grade experience.

The product is available through Flight1 and simMarket. For users moving to newer platforms, iFly has recently released highly-rated versions of the 737 MAX for MSFS 2024, which continues their legacy of high-fidelity simulation. The iFly Boeing 737 NG Full Review
The required text for installing new liveries on the iFly 737NG for FSX is found in the aircraft.cfg file, typically within the SimObjects\Airplanes\iFly 737-800 folder. This configuration involves pasting a specific template, updated with the next sequential [fltsim.X] number, to register the new paint scheme. It is generally safer to use the iFly Configuration Manager for automated installations to avoid errors, and high-definition textures may require specific fsx.cfg settings.

Historically, the iFly 737 has been priced lower than its main competitor. Combined with the included 737-800, -700, -600, and -900 variants, it offers immense value for money.
The "hot" moniker also applies to the livery community. Because the iFly uses a standard texture mapping (similar to the default 737 but higher resolution), repainters love it. You can find virtually any airline:
Must-have mods to make it "Hot":
Below is a short, clear text explaining how to hot-start the iFly 737 in Microsoft Flight Simulator X (FSX). It assumes the aircraft is powered by ground electrical and APU/DC power is available for systems but engines are shut down.
When you search "ifly 737 fsx hot", you usually get the full package. The standard product includes the "Holy Trinity" of Next Generation 737s:
Each variant flies differently. The -600 rotates almost immediately, while the -900ER requires significant back pressure on the yoke. The flight dynamics are modeled using real-world Boeing data (within the limits of FSX’s flight model).
Also included: The Boeing Business Jet (BBJ) variant with auxiliary fuel tanks for transatlantic hops.
Here is the killer feature: Frame rates. The iFly 737 is famously lightweight. Where the PMDG 737 could drop your FPS from 30 to 12 at a complex airport like FSDT JFK V2, the iFly would only dip to 24. For FSX users still flying on Intel Core 2 Duo or early i5 processors, this was a lifesaver.
If you’ve been scrolling through flight simulation forums or browsing the virtual skylines of FSX (Microsoft Flight Simulator X) recently, you’ve likely seen the term "iFly 737 FSX hot" popping up.
At first glance, it sounds like a search term for a trend, but for seasoned simmers, "hot" can mean a few different things. Are we talking about a "hot" new release? A "hot" start procedure? Or simply an aircraft that is still the hottest ticket in town despite its age?
Let’s dive into why the iFly 737 Advanced series remains a scorching topic in the FSX community and why it might deserve a spot in your hangar.
