Issue Description
I am experiencing very frequent WASM crashes with the A350-900, across multiple flight phases and different routes.
Out of approximately 10 flights, 6 resulted in a WASM crash, making the aircraft unreliable to operate.
This significantly degrades the experience. At this stage, flying the A350 feels unstable and unpredictable, as crashes occur regularly without a single consistent trigger.
Because of this, I am currently reconsidering using this aircraft, as most flights do not complete successfully.
Attached, you will find a compressed file containing the requested files. If you require any further information, please do not hesitate to ask.
Reproducible Scenario (Confirmed)
Taxi after landing (reproduced twice)
Normal landing
Vacating the runway
Taxiing after runway exit
→ WASM crash occurs
This scenario has been reproduced 2 times under similar conditions.
Other Observed Scenarios
FMS / Approach Entry (3 occurrences)
While entering approach procedures in the FMS
Example: Seoul → Tokyo (OFP available)
→ WASM crash
At Gate
During IRS alignment
→ WASM crash
In-flight Failures
Sudden loss of navigation
Full WASM failure without orange screen indication
Reproducibility Summary
Approx. 60% crash rate
Occurs across:
Taxi phase
FMS programming
Gate operations
In-flight
Not route-specific
Additional Files Available
Console screenshots
WASM error screenshots
OFP (PDF)
Autosave (.bin prior to crash)
Impact
These repeated WASM crashes severely impact usability and prevent normal operation of the aircraft.
At the moment, the experience is highly inconsistent and unreliable, making it difficult to complete flights.
Final Notes
Given the frequency and variety of triggers, this appears to be a broader stability issue rather than a single isolated bug.
I am happy to provide additional logs, files, or test scenarios if needed.
