Unlocking Realistic Airport Taxiways in Simulation

For any dedicated city-building enthusiast who has delved into the intricacies of airport management within their favourite simulation game, a common frustration often surfaces: the seemingly rigid and unrealistic behaviour of aircraft taxiing. It’s a familiar sight – a colossal jet, having just landed, lumbering all the way to the very end of a sprawling runway before finally making its exit onto a taxiway. Or, conversely, preparing for departure, it must traverse the entire length of the runway before initiating its take-off roll. This lack of mid-runway exits and entries not only detracts from the visual authenticity of our meticulously crafted airports but also severely impacts operational efficiency, creating bottlenecks and unnecessary delays. While the game's official Airport DLC brought a wealth of new features, this particular limitation remained a persistent thorn in the side of many a virtual airport manager. However, through a stroke of unexpected luck and a bit of unconventional experimentation, a clever workaround has been discovered that can fundamentally transform how aircraft navigate your runways, bringing a much-needed dose of realism and fluidity to your bustling airfields.

The Persistent Problem: Vanilla Limitations

The core issue stems from the game's default design regarding runway and taxiway connections. In the vanilla game, runways are primarily designed with entry and exit points exclusively at their extreme ends. This design choice, while perhaps simplifying the underlying pathfinding logic for the developers, creates a significant disconnect from real-world airport operations. Modern airports, especially those handling high volumes of traffic, rely heavily on a network of high-speed taxiway exits – often referred to as rapid exit taxiways (RETs) – that allow landing aircraft to vacate the runway quickly, minimising runway occupancy time. Similarly, aircraft preparing for take-off can often enter a runway at an intersection closer to their gate, reducing taxiing distance and time.

Without these intermediate connections, our simulated airports suffer from several drawbacks. Firstly, efficiency takes a hit. A landing aircraft occupying the runway for an extended period, slowly trundling to the very end, prevents subsequent aircraft from landing or taking off. This leads to frustrating queues, increased holding patterns, and a general reduction in the airport's overall capacity. Secondly, the visual fidelity is compromised. A perfectly laid-out airport with multiple runways and a complex taxiway network still looks somewhat amateurish when every plane behaves as if it's operating on a single, linear track. And if you’ve tried to force a connection between a taxiway and the middle of a runway using standard in-game tools, you’ll be all too familiar with the dreaded “network not connected” or “cannot connect here” error messages, signalling the game’s hardwired limitations. This rigid system forces a less dynamic and less realistic flow, making it challenging to truly optimise airport operations and achieve that coveted look of a smoothly running, professional aviation hub.

The Accidental Discovery: A Parallel Path to Realism

The solution to this long-standing grievance wasn't found through complex modding or deep dives into game code, but rather through a serendipitous accident – the creation of a parallel runway. This seemingly unrelated action inadvertently revealed a loophole in the game's networking logic, a way to trick the system into allowing connections where it normally wouldn't. This method, while a bit unconventional, has proven to be remarkably effective in enabling mid-runway taxiway connections, opening up a world of possibilities for more realistic airport designs.

To embark on this journey of enhanced realism, you'll need a few essential tools from the community's vast collection of modifications. At a minimum, the Network Multitool mod is absolutely indispensable; it provides the precision and flexibility required to manipulate network nodes and segments in ways the vanilla game simply doesn't allow. While not strictly mandatory for the core concept, you'll also find the Find It! 2 mod incredibly useful for quickly locating specific taxiway assets, especially if you prefer custom content over the default DLC offerings. The Move It! mod is another highly recommended addition, providing unparalleled control over object placement and manipulation, which will be crucial for refining your connections. Lastly, having a way to toggle Road Anarchy (often part of mods like TM:PE or a standalone anarchy mod) is advised, as it can often bypass stubborn connection rules, though its exact necessity for every step of this particular process may vary based on your specific setup and game version. These tools, when used in conjunction, empower you to transcend the game's inherent limitations and sculpt your airport exactly as you envision it.

Step-by-Step Guide: Implementing Mid-Runway Taxiways

Here’s the breakdown of how to achieve these elusive mid-runway connections:

1. Prepare Your Ground: Begin by laying down a standard runway from the Airport DLC. This will be your primary, functioning runway where you want your mid-runway exits/entries. Ensure it's straight and properly aligned with your overall airport plan.

2. The Temporary Parallel Runway: This is the crucial step. Immediately adjacent to your primary runway, build a second, parallel runway. This temporary runway should be built as close as possible to the primary one without overlapping. Its purpose is to temporarily confuse the game's network logic.

3. The Deletion Trick: Now, delete the *original* runway you built in step 1. For some reason, attempting to delete the first runway normally can be problematic or leave behind residual network data. This is where the Move It! mod comes in handy. Select the entire segment of your original runway using Move It! and then delete it. This ensures a clean removal, leaving only the newly placed parallel runway (which will become your actual working runway).

4. Connect Your Taxiways: With your 'new' runway in place, you can now attempt to connect your taxiways. The user who discovered this method primarily used taxiways from the Find It! 2 mod, noting that the DLC taxiways sometimes slowed things down. However, it's worth experimenting to see if this method also works effectively with the official Airport DLC taxiways. The key here is precision.

5. The Secret to Success: Connecting Between Nodes: This is the most important detail. When trying to connect your taxiway to the runway, do NOT attempt to connect it directly to an existing node on the runway. If you try to snap it to a node, the game will likely give you the familiar "cannot connect here" message. Instead, use Network Multitool to connect the taxiway *between* two nodes on the runway segment. This creates a new, intermediate node on the runway, which the game then seems to accept as a valid connection point for the taxiway. Ensure Road Anarchy is enabled when making these connections, as it often helps bypass strict collision or placement rules.

6. Give It Time: Once your connections are made, let the simulation run for a few game cycles. It often takes a little while for the game's AI and pathfinding algorithms to register the new connections. You'll soon start seeing aircraft utilising these newly created mid-runway exits and entries, confirming your success.

Understanding the Mechanics: Why Does This Work?

While the exact underlying game logic remains opaque, we can hypothesise why this parallel runway trick functions. It seems likely that when you build a second runway immediately adjacent to an existing one, the game's network generation routines, particularly when dealing with large, linear assets like runways, might momentarily extend or redefine the 'active' network boundary for that area. When the original runway is then deleted (especially using a robust tool like Move It!), the game might fail to fully revert the network data associated with that space. The newly placed, now primary runway, then inherits or somehow interacts with this residual or modified network data, making it 'permissive' to connections that would otherwise be forbidden. By connecting *between* nodes with Network Multitool, you're essentially forcing the creation of a new node on a segment that the game now implicitly allows to be intersected, rather than trying to snap to a pre-defined, 'locked' node. Road Anarchy further assists by overriding typical placement restrictions, allowing for more aggressive network manipulation. This combination of temporary network manipulation and precise node creation seems to bypass the game's standard validation checks for runway connections, effectively 'unlocking' intermediate access points.

The Transformative Benefits of Intermediate Connections

Implementing mid-runway taxiways fundamentally changes the dynamics of your airport, offering substantial improvements in both realism and operational efficiency.

• Enhanced Realism: This is perhaps the most immediately gratifying benefit. Your airport will instantly look and feel more like a real-world aviation hub. Observing aircraft seamlessly vacating the runway via a high-speed exit after landing, or lining up for take-off from a mid-field entry point, adds an incredible layer of authenticity that the vanilla game simply cannot replicate. It transforms your airport from a merely functional space into a vibrant, believable ecosystem of air traffic.

• Improved Efficiency and Throughput: From an operational standpoint, the gains are immense. Landing aircraft can clear the runway much faster, significantly reducing runway occupancy time. This means the runway becomes available for the next arriving or departing aircraft sooner, leading to a higher potential for simultaneous operations. Reduced taxiing distances also contribute to overall efficiency, as aircraft spend less time on the ground, theoretically saving 'fuel' and definitely improving the flow of traffic. This improved flow translates directly into a higher capacity for your airport, allowing you to handle more flights without experiencing frustrating bottlenecks or long queues, which are common issues in high-traffic vanilla airports.

• Reduced Ground Congestion: By allowing planes to exit or enter at multiple points, you distribute ground traffic more effectively. Instead of all aircraft converging on the very ends of the runway, they can spread out across your taxiway network, reducing instances of planes waiting for others to clear congested intersections. This creates a smoother, more fluid movement of aircraft across your entire airfield.

• Aesthetic Appeal: Beyond pure function, the ability to create bespoke taxiway connections allows for far greater aesthetic customisation. You can design more complex, visually engaging taxiway networks that truly reflect the intricate layouts of real-world airports, making your creations even more impressive and unique.

Navigating the Caveats: Considerations for Implementation

While this workaround is a game-changer, it's not without its quirks. As the original discoverer noted, there are a few behaviours to be aware of:

• Shortened Take-offs: If you connect taxiways that lead *towards* the runway (i.e., an entry point for take-offs), aircraft might occasionally use these for take-off, even if they are relatively far down the runway. This can result in what looks like a shortened take-off roll. While this can look odd if the aircraft takes off too quickly, it's not entirely unrealistic for certain aircraft types or under specific operational conditions (e.g., light loads, long runways). Careful placement of these entry points – ensuring they are far enough down the runway to allow for a realistic take-off roll – can mitigate this visual anomaly.

• Premature Exits: Conversely, if you have outbound taxiways connected too close to the landing threshold, aircraft might sometimes use them even if they’ve only just touched down. This can look equally strange, as planes might veer off the runway almost immediately after landing. Again, strategic placement is key. Design your rapid exit taxiways to be positioned further down the runway, allowing for a sufficient landing roll before the exit point.

• Asset Compatibility: The original discovery noted better performance with Find It! 2 taxiways compared to DLC ones, suggesting that DLC assets might sometimes cause performance slowdowns or behave differently. It's advisable to experiment with both to see what works best for your specific setup and desired aesthetic. If you encounter issues, switching between asset types might resolve them.

• Precision and Patience: Achieving perfect alignment and seamless connections requires a good degree of precision with Network Multitool and Move It!. There might be a learning curve involved in mastering these mods to get the exact look and functionality you desire. Don't be afraid to iterate and adjust.

Optimising Your Mid-Runway System

To get the most out of this fascinating workaround, consider these optimisation tips:

• Strategic Placement: Design your mid-runway exits as high-speed turns (often 30-degree angles to the runway centreline) placed at intervals appropriate for typical landing speeds and aircraft types. For entry points, consider placing them further down the runway to allow for a more realistic take-off roll, especially for larger aircraft.

• Dedicated Use: You can, if you wish, design specific mid-runway connections primarily for landings (exits) and others primarily for take-offs (entries), though the game's AI may still use them interchangeably. Understanding the AI's tendencies is key.

• Runway Length Matters: The longer your runways, the more flexibility you have for placing multiple mid-runway connections, further enhancing throughput.

• Experimentation is Your Friend: This method isn't an exact science given it's a workaround. Don't be afraid to experiment with different angles, distances, and connection points to find what works best for your specific airport layout and traffic flow.

Comparative Analysis: Vanilla vs. Custom Mid-Runway Taxiways

Frequently Asked Questions (FAQs)

Do I really need all those mods?

Yes, Network Multitool is crucial for this method as it allows you to create nodes between existing ones. Find It! 2 and Move It! are highly recommended for ease of use and precision in deleting and placing assets, while Road Anarchy often helps in bypassing connection restrictions.

Will this workaround break my save game?

While directly modifying networks always carries a slight risk, this method is generally stable as it relies on manipulating existing game mechanics. However, it's always good practice to back up your save game before undertaking significant network modifications.

Can I use this for both landing and take-off runways, or only one direction?

You can use it for both! The connections you create will be bidirectional for aircraft. However, as noted in the caveats, you'll need to strategically place your connections to minimise visual oddities like very short take-offs or premature exits, depending on how you intend each part of the runway to be used.

Why do planes sometimes take off from the middle of the runway through a taxiway connection?

This occurs because the game's pathfinding sees the newly created mid-runway connection as a valid entry point onto the runway. If it's the most efficient path for an aircraft to reach the runway from its gate, the AI will use it. Careful placement can mitigate this, ensuring entry points are far enough down the runway for a more realistic take-off roll.

Does this method work with all custom aircraft assets or just the DLC ones?

This method modifies the underlying network structure, not the aircraft assets themselves. Therefore, it should work seamlessly with all aircraft assets, whether they are from the DLC, workshop, or custom packs.

What if I can't delete the original runway with the normal delete tool?

As described in step 3, you'll likely need to use the Move It! mod to select the entire runway segment and then delete it. Move It! offers more robust deletion capabilities than the standard in-game tool, ensuring a clean removal of the network segment.

Conclusion

The discovery of this simple yet ingenious workaround for creating mid-runway taxiways is a testament to the community's ingenuity and dedication to pushing the boundaries of what's possible within our favourite city-building simulation. While it requires a few additional mods and a bit of patience to master, the payoff in terms of enhanced realism and improved operational efficiency for your virtual airports is immense. No longer will you have to endure the sight of aircraft needlessly taxiing to the very ends of your runways. With this technique, you can truly design and operate an airport that feels vibrant, dynamic, and authentically bustling. So, fire up your game, install those essential mods, and prepare to transform your airport into the realistic aviation hub you've always dreamed of.
