Sensor Failures in Flight 888

The video explores the investigation into the XL Airways Flight 888 incident over Perpignan, France. Investigators focus on the failure of critical sensors that misled the flight computer about the plane's angle of attack. The investigation reveals that water ingress during maintenance, specifically from high-pressure cleaning, may have caused the sensors to freeze at high altitudes, leading to the plane's stall. A recreation of the flight confirms the hypothesis, showing that frozen sensors prevented the flight computer from detecting the true angle of attack.

What was the initial finding about the sensors on flight 888?

• They were functioning normally.

• They failed at different times.

• They failed simultaneously.

• They were not installed.

What role do angle of attack sensors play in flight?

• They manage passenger comfort.

• They control cabin pressure.

• They help monitor the plane's position.

• They measure fuel levels.

What was the initial hypothesis about the sensor malfunction?

• They were incorrectly installed.

• They were outdated models.

• They were stuck due to ice.

• They were damaged by birds.

Why was weather ruled out as a cause for the sensor issue?

• The sensors were waterproof.

• The weather was clear during the flight.

• The plane was flying at low altitude.

• The plane flew through a storm.

What maintenance procedure potentially led to water ingress in the sensors?

• Using a high-pressure hose.

• Replacing the sensors.

• Changing the flight computer.

• Painting the plane.

What was the purpose of recreating flight 888 conditions?

• To test new sensors.

• To confirm the freezing hypothesis.

• To train new pilots.

• To check fuel efficiency.

At what altitude did the sensors stop working during the test?

• 10,000 feet

• 20,000 feet

• 32,000 feet

• 40,000 feet

What was the result of the sensor freezing during the test?

• The sensors started working again.

• The plane's speed increased.

• The flight computer failed to prevent stalling.

• The plane's altitude decreased.

What did the investigators need to prove about the sensors?

• They were outdated.

• They were jammed by ice.

• They were too sensitive.

• They were incorrectly calibrated.

What was the final conclusion about the sensor failure?

• It was caused by ice formation.

• It was a result of pilot error.

• It was due to a manufacturing defect.

• It was due to a software glitch.
