A Critical Flaw in Aircraft Design We Can No Longer Ignore, A Simple Solution | AI 171

In the wake of the recent Air India 787 crash — where both engines reportedly shut down mid-flight due to fuel switches most likely being moved to cutoff , either manually or due to some glitch— I’m left with a question that simply won’t go away:

In the odd case that this was out of malicious intent, how is it possible that the only thing standing between a functioning aircraft with over 250 souls on board and total loss of power is two adjacent toggle switches, fully accessible to a single person?

The aviation industry is famous for its near-zero tolerance for risk:

• Triple-redundant hydraulics.

• Dual autopilot systems.

• Multiple electrical and communication backups.

• Even lavatory smoke detectors have redundancy.

And yet, the kill switches for both engines — the on/off for thrust — are right next to each other, unguarded, and operable by one person, without confirmation. It’s stunning.

🛑 We Trust, but We Don’t Verify

Historically, aviation has trusted its pilots. And that trust is well-placed — in almost all cases.

But that’s the problem: we’ve designed systems around good intentions, not around edge-case malice or mental breakdowns. As recent incidents have shown — from Germanwings to China Eastern to now possibly Air India AI-171 — malice or confusion in the cockpit is not theoretical. It’s real.

This isn’t a matter of blaming crews. This is a design-level blind spot. They should just make it as hard as possible to make one party have enough power to bring down the plane — whether this turns out to be the case in the story of AI 171 or not!

🔧 The Fix is Incredibly Simple

All it would take to prevent or at least mitigate the possibility of this specific failure mode to a significant statistical extent is:

• Physically separating the engine fuel cutoff switches, placing one near the captain, and the other near the first officer. One switch to the left of the pilot sitting on the left and the other to the right of the pilot sitting on the right.

• Or requiring dual confirmation (like missile launch panels or secure software deploys).

• Or adding a software interlock in FADEC, preventing in-air shutdown of both engines without a multi-step override.

🔢 How This One Change Slashes the Risk

Let’s say the chance of a pilot acting maliciously is extremely rare — around 1 in 20 million flights, based on past incidents like Germanwings and China Eastern.

Right now, a single pilot can access both engine fuel cutoff switches, so that rare 1-in-20-million case can directly lead to both engines shutting down.

But if you simply physically separate the switches, requiring both pilots to act together, the risk drops dramatically given most airliners are more than capable of flying on one engine without any problem. Now it would take two pilots being malicious at the same time, which makes the probability closer to 1 in 400 trillion flights.

Keeping math TED Talk out of this, that’s a 200 million times reduction in risk — from a simple design change. That is not just statistically but astronomically significant!

These aren’t radical ideas. They’re borrowed from aviation itself — and from other high-risk industries like defense, nuclear, and aerospace operations. We already do this for things far less catastrophic than full engine failure.

🤯 Why Was This Missed?

That’s the part that’s hard to digest.

The idea that such a critical failure mode was left unguarded — in an industry that prides itself on eliminating single points of failure — is deeply concerning. The cockpit crew in the Air India crash reportedly didn’t understand what had just happened. Whether it was mechanical, human error, or intentional action — the very fact that such an action was possible without any redundancy should be unacceptable going forward.

📣 Call to Action

This isn’t about hindsight. It’s about fixing what’s clearly broken.

Boeing, Airbus, the FAA, EASA, DGCA, and all major regulators should re-examine the design assumption that engine cutoff switches don’t require isolation or dual confirmation.

Flying is too safe — and passengers put too much trust in engineers — for us to allow the airplane’s “power switch” to remain this vulnerable.
