10 Flight Simulator Myths That Might Be Costing You

We're changing it up a little today. With this blog post we're going to be separating aviation fact from fiction in the sim bay - let us know if you like the format and we can do more like this in the future.

Most people outside this industry have no idea how hard it is to keep a multi-million dollar simulator running like clockwork. To a passenger, it’s a big box on legs. To a pilot, it’s their sweat box for the day. But for the technicians, engineers and managers behind the scenes, it’s a constant balancing act of hardware, software, and strict compliance with regulations.

When you’re new to the sim bay, or even if you’ve spent years in the cockpit, it’s easy to pick up some "common wisdom" that isn’t actually true. These myths can lead to wasted hours, failed audits, and unnecessary stress.

Let’s look at ten of the biggest myths we see in the industry and find out what’s actually happening behind the scenes.

1. "It’s Just a Fancy Video Game"

This is the one that makes every tech’s eye twitch. While consumer games look impressive, a qualified Full Flight Simulator, or FFS, is a different beast. Every bank, climb, and system failure is backed by real validated aircraft data.

It doesn’t just need to look right, it has to behave right within tiny margins. If the physics are off by even a fraction, the training value disappears.

Real flight simulation is about moving math, not just moving pictures.

2. "If It Passes the Test Once, It’s Good Forever"

We wish this were true (oh god how we wish it was true!), but qualification is a snapshot; a point in time, not a permanent status. Simulators are "living" systems where parts age, software gets patched, and projectors dim over time.

Without a solid process for checking 'drift', a simulator can slowly move away from its originally qualified standard. This often happens so slowly that nobody notices until the next big regulatory audit reveals a major gap.

3. "Flight Simulator Maintenance Is Mostly Reactive"

If you’re only fixing things when they break, the sim is running you, you aren’t running the training centre. The best teams move toward predictive maintenance. They look at trends, like how long a power supply usually lasts or when a motion leg starts to show signs of wear, and they swap parts before the training schedule takes a hit. But I hear you say "But, we get MTBF data from the manufacturer?" - which is all well and good; but anyone who has worked in this industry for any reasonable length of time will tell you that the MTBF (Mean Time Between Failure) data is about as reliable as keeping your password written on your palm in pen ink. Sim operators worth their salt are compiling, collating and calculating 'real-world MTBF' values to ensure predictive and preventative maintenance is effective.

Being proactive is the difference between a smooth morning and a cancelled training session.

4. "Visual Quality Is Only About Pixels"

A high-resolution image is great, but in a simulator, timing is king. If the 'out-the-window' view has even a tiny delay (beyond what's allowed in the regulations) behind the pilot’s control input, it can cause motion sickness or, worse, poor training habits. We all love the look of fluffy clouds, but consistency, alignment, and low latency matter way more than pretty clouds.

You want a stable image that matches the feel of the flight, not just a sharp one.

Then of course you also have to make sure the colours are balanced with consistently low Delta E values, the blend zones aren't blurry or misaligned, and the geometric alignment is matched up precisely with the designed field of view.

5. "Older Simulators Are Obsolete"

Just because a device has been around for twenty years doesn’t mean it belongs in a museum. Many older sims are incredibly reliable because their teams know every tiny detail about its sub-systems and software. With the right updates to the visuals or the host computer, an 'old workhorse' can often outperform a brand-new device that is still having teething issues.

Age is just a number if the maintenance is disciplined.

6. "Motion Systems Should Feel Dramatic"

In the real world, you feel a "thump" when the gear goes down, but it isn't an earthquake. Some think the crazier the motion, the better the sim. In reality, motion is about cueing, which means giving the pilot’s inner ear (aka the vestibular system) just enough info to believe the movement. Over-the-top motion actually ruins the realism and can lead to simulator sickness.

Realism is about the quality of the move, not the size of it.

7. "Technicians and Instructors Speak Different Languages"

It often feels that way, but they have the same goal: a pilot who is ready for anything. When a tech understands why an instructor cares about a specific flight director glitch, the fix happens faster. When they work together, the defect list gets shorter and the training gets better.

Communication is just as important (you could even argue more important) as a multimeter when it comes to fixing a problem.

8. "Regulators Are the Enemy"

Or sometimes "Regulators are out to get us", or "Regulators are there to make our lives more difficult"...

It’s easy to feel nervous when an auditor walks in with a clipboard (not sure the last time we actually saw a physical clipboard, we're showing our age here). But they aren't looking for reasons to shut you down. They are looking for proof that you have control over your processes. A clean, well-documented maintenance log is often more impressive to a regulator than a shiny new coat of paint. They want to see that you find your own problems and fix them.

9. "Modernising Is Too Expensive"

People often think you have to replace the whole simulator to stay current. Usually, you don’t. Small, smart updates, like moving to more reliable solid-state drives or updating a single sub-system, can add years of operational life to a device.

You can get a huge boost in reliability for a fraction of the cost of a new machine if you know where to spend the money.

10. "The Technology Is the Hardest Part"

Actually, the people are the most important part of the equation. You can have the best hardware in the world, but if your team doesn't have a clear way to share knowledge or document their wins, the machine will eventually fail.

Success in this industry is built on good habits, mentoring, and clear procedures, not just circuit boards and new tech.

Getting the Most Out of Your Operation

The 'secret' to a high-performing training centre isn't a secret at all, it’s just a mix of discipline, clear documentation, and a deep understanding of the machine. Whether you are a new tech finding your footing or a manager looking to tighten up the ship, the goal is always the same: reliability and trust.

We've spent years in training centres and around devices to know exactly where the hidden 'gotchas' live. We don't just look at the hardware, we look at the processes that keep that hardware running.
