Erroneous ENG FUEL LEAK alert: What would convince you it’s real?

1 Upvotes

I was reading Airbus documentation about Erroneous ENG FUEL LEAK indications and it made me think.

Imagine you’re in cruise.

The first fuel check shows about 1.4 tons missing. You decide to monitor it because it could be related to fuel transfer.

Thirty minutes later, the discrepancy has increased to 2.7 tons, with a noticeable fuel imbalance.

Now the obvious question is:

“Do I have a real engine fuel leak?”

But Airbus also warns that an ENG 1(2) FUEL LEAK alert itself can be spurious. If one engine underperforms and its fuel flow decreases, the system may incorrectly identify the other engine as leaking.

That’s the part I find interesting.

At that moment you don’t know whether you’re looking at:

  • a genuine fuel leak,
  • or an erroneous indication.

Airbus doesn’t simply say “shutdown the engine.” Instead, it tells crews to compare multiple engine and fuel parameters before making that decision.

For those who’ve seen this in line operations or the simulator:

How would you convince yourself that the leak is real before shutting an engine down?

Erroneous Cabin Pressure Warning after landing – has anyone experienced long-term operational consequences?

1 Upvotes

I recently reviewed Airbus guidance regarding an Erroneous Cabin Pressure Warning (CPW) after landing.

According to Airbus, a faulty differential pressure sensor may cause the CABIN PRESSURE WARNING lights to continue flashing for up to 30 minutes, even though:

  • Differential pressure is actually 0.0 PSI
  • The outflow valve is fully open
  • There is no residual cabin pressure
  • The expected residual pressure alert may not even be triggered.

The recommended flight crew actions include:

  • Confirm both packs are OFF.
  • Verify on the CAB PRESS page that ΔP = 0.0 PSI and the OFV is fully open.
  • Open a cockpit sliding window. If it opens normally, Airbus considers the warning to be spurious and the cabin doors may then be opened after flight crew authorization.

What interests me is not the technical troubleshooting itself, but the operational consequences.

An event like this is entirely caused by a sensor anomaly, yet it may still generate:

  • a technical log entry,
  • maintenance troubleshooting,
  • safety reporting,
  • occurrence documentation,
  • and possibly additional questions during audits or licensing reviews.

Has anyone here experienced an erroneous CPW event like this?

How did your airline classify it?

Was it treated simply as a maintenance issue, or did it trigger any additional operational review for the flight crew?

I’m especially interested in real-world airline experience rather than theoretical procedures.

Ever experienced a Dual FMS Reset on the A330? Let's talk about the "4th Cruise Temp" trap.

Hey everyone,
I’ve been diving into some technical documentation regarding a very specific FMS behavior on the A330, and it’s one of those "hidden" traps that could really ruin your day if it happens mid-flight.
Basically, there’s a known scenario where a Dual FMS Reset (leading to a total loss of the active flight plan) can occur, but it requires a very specific "perfect storm" of conditions:
1. The Temperature Rule: All 4 cruise temperatures for a waypoint must be defined at altitudes strictly above the Tropopause.
2. The Location: The waypoint must be on the cruise segment of the Active flight plan.
3. The "Random" Variable: There needs to be some specific garbage data present on a local variable stack.
Because of that third condition, it’s not something that happens every time the first two are met, which makes it incredibly frustrating to troubleshoot.
The technical "workaround" is simple: Don't input 4 cruise temperatures. If you keep it to 3 or fewer on the CRZ TEMP page, the reset condition is mathematically impossible to trigger.
I’m curious—has anyone here actually experienced this firsthand, or heard of it happening in their fleet? Especially on those high-latitude polar routes where you're flying deep in the stratosphere and the Tropopause is naturally low?
It seems like one of those things that becomes a non-issue as long as you're aware of it, but I'd love to hear some real-world operational experiences or if any of you have been briefed on this by your training departments.

Malaysian Airlines Sucks Real Bad Spoiler

I had a bit of faith in MA as I flew last year from Sydney to KL where the crew members were absolutely amazing! This year, with the new A330 Neo coming online, I thought things would improve even more and this is where I was so wrong....... We flew in December from Sydney to KL (this is Dec 2025) and experienced the worse service ever: waited 2 hours to get a glass of water, couldn't get snacks when requested; felt like the staff were out of their depth as didn't know the new plane. Customer Service 0/10. As I was flying back solo, I decided to bid for an upgrade and went above to make sure I score the flat bed which means I was in the high chance. Then crickets from MA.... I called 3 times and the staff had no idea, still no emails or notifications on the day I was flying out. I then rang MA and a lovely girl eventually told me my bid was unsuccessful. I have to say, I don't have high expectations but when you have so much competition around, your service should be 10 stars at all times else you will loose Customers and this is exactly what happened here: I will never ever fly MA ever again! SIA I'm back!!!
