Imagine a massive passenger jet, its tail scraping the runway in a heart-stopping moment during landing. This isn't a scene from a disaster movie; it's exactly what happened to a Cathay Pacific Airbus A350-1000 at Hong Kong International Airport recently. But here's where it gets controversial: while the aircraft landed safely after a go-around, the incident raises crucial questions about tail-strike prevention and pilot training.
The flight, arriving from Ho Chi Minh City, experienced an unstable approach, prompting the crew to abort the landing and initiate a go-around. During this maneuver, the tail of the aircraft struck the runway. And this is the part most people miss: the tail strike occurred during the go-around, not the initial touchdown, highlighting the complexities of managing aircraft pitch during critical phases of flight.
Despite the incident, the aircraft climbed normally and successfully landed on its second attempt, with no injuries reported. However, the four-year-old jet has been grounded for four days, undergoing thorough engineering inspections and repairs before it can return to service. This event has sparked an operational review within Cathay Pacific, with a renewed focus on tail-strike prevention technology and pilot preparedness.
Tail strikes, though rare, are a serious concern. They occur when the rear underside of an aircraft contacts the runway due to excessive nose-up pitch during takeoff or landing. Airbus data reveals that 65% of tail strikes happen during landing, while 25% occur during takeoff. To mitigate this risk, Airbus equips its aircraft with pitch-limit cues on the Primary Flight Display below 400 feet and audible “PITCH PITCH” warnings when pitch exceeds safe thresholds.
Boeing, on the other hand, introduced its Tail-Strike Protection system on the 777-300ER in 2003, which automatically adjusts the elevator to prevent excessive rotation during takeoff. These technologies are vital, but they underscore the importance of pilot skill and training.
Go-arounds, while routine safety procedures, demand precise aircraft handling. Pilots must simultaneously apply maximum thrust (TOGA) and pitch-up input, relying on autopilot and autothrust systems to manage the climb. However, this maneuver can create a pitch-up moment that requires careful modulation of power and control to avoid over-rotation and structural damage.
Commercial pilots undergo rigorous simulator training every six months, practicing scenarios like engine failures, rejected takeoffs, unstable approaches, and go-arounds. These sessions reinforce manual handling skills and prepare pilots for non-routine situations.
During aircraft certification, manufacturers conduct controlled tail-strike tests using a protective tail-skid to determine the Minimum Unstick Speed (Vmu). This speed defines the lowest takeoff velocity at which the aircraft can safely lift off with maximum pitch-up attitude, serving as a critical flight-performance reference.
Here’s a thought-provoking question: With advancements in technology and pilot training, why do tail strikes still occur? Is it a matter of human error, technological limitations, or a combination of both? Share your thoughts in the comments below.
