A recent aviation incident has sparked a crucial discussion about flight safety and pilot training. An emergency landing at Hong Kong International Airport has grounded a Cathay Pacific A350, highlighting the importance of tail-strike prevention and pilot preparedness.
The story begins with a Cathay Pacific flight from Ho Chi Minh City, which encountered a tail strike during a missed approach at HKG. Thankfully, the crew's quick thinking averted disaster, and the aircraft landed safely on its second attempt. But here's where it gets controversial: the jet has been grounded for four days, awaiting engineering inspections and repairs. This event has prompted a review of operational procedures and a renewed focus on tail-strike prevention technology and pilot training.
A tail strike occurs when the aircraft's aft underside makes contact with the runway due to excessive nose-up pitch during takeoff or landing. In this case, the Airbus A350-1000 veered left during its final approach to Runway 07C. The flight crew's decision to initiate a go-around was crucial, as the impact occurred during this maneuver, not during touchdown. Despite the strike, the aircraft climbed normally to 6,000 feet before attempting a second, successful landing.
FlightRadar24 data confirms the safe landing, albeit 34 minutes behind schedule. The grounded aircraft, a mere four years old, has not flown any commercial flights since. Simple Flying reports that Cathay Pacific is conducting thorough structural inspections and repairs, with plans to release further details once available.
Tail strikes are more common during landing than takeoff, with Airbus data indicating a 65% occurrence during landing and 25% during takeoff. To mitigate this risk, Airbus integrates pitch-limit cues on the Primary Flight Display below 400 feet and audible warnings when pitch values exceed thresholds. Boeing's Tail-Strike Protection system, introduced on the 777-300ER in 2003, automatically adjusts elevator settings during takeoff to prevent excessive rotation rates.
Go-arounds require precise aircraft handling, as pilots must simultaneously apply TOGA thrust and pitch-up input. Autopilot and autothrust systems then collaborate to provide a powerful climb, but this pitch-up moment demands careful modulation of power and control input to avoid over-rotation and structural damage.
Commercial pilots undergo rigorous simulator assessments every six months to practice manual handling and respond to non-routine situations. These sessions simulate engine failures, rejected takeoffs, unstable approaches, and go-around execution, ensuring pilots are prepared for the unexpected. During aircraft certification, manufacturers intentionally conduct controlled tail-strike tests using a protective tail-skid to determine the Minimum Unstick Speed (Vmu), the lowest possible takeoff speed at which the aircraft can safely lift off with maximum pitch-up attitude.
Vmu serves as a critical flight-performance reference, and its determination is a key part of the certification process. Stay tuned for further updates on this incident and the ongoing efforts to enhance aviation safety.
