German Accident Investigation Reinforces Dangers of Wake Turbulence
Key Takeaways:
- On January 7, 2017, a German-registered Bombardier Challenger 604 was severely damaged and two passengers severely injured after encountering extreme wake turbulence from an Airbus A380 over the Arabian Sea.
- The Challenger lost control and plunged over 9,000 feet, exceeding structural limits, after passing 1,000 feet below the opposite-direction A380, whose type the pilots were unaware of.
- The incident highlights the importance of flight crews' vigilance for unexpected hazards, even in good weather, and the potential benefit of procedures like strategic lateral offset to mitigate risks from heavy aircraft wake.
