On February 24th, a cargo plane's journey went off track. The plane, set on autopilot, veered off its course and kept flying well past its destination of Lihue Airport in Hawaii.
This wasn't a minor deviation. The craft, operated by Kalitta Air, strayed 25 nautical miles off track. Before anyone knew it, the large Boeing 747 airliner was found more than 50 miles well beyond its scheduled endpoint. The astounding error in navigation was the result of two pilots who had drifted off to sleep while the aircraft was on autopilot.
The ordeal came to a head when the ground control lost contact with the pilots. Feeling increasingly alarmed, they made numerous unsuccessful attempts to wake the pilots using the cockpit alerting system.
As the situation progressed, the tower controllers attempted to get in touch with other aircraft in the vicinity. The hope was that they might have better luck in communicating with the errant cargo plane. The procedure is referred to as 'Guard frequency' in aviation parlance.
Their efforts, unfortunately, did not yield the desired result. The cargo plane, unmanned and uncontrollable, kept moving on its preset course.
Meanwhile, the ground control was brainstorming their next possible steps. Left with an incommunicado cargo plane, they wondered how to prevent an impending disaster.
At this point, the aircraft had diverted so much from its course that it was no longer an issue confined to merely the control tower of Lihue Airport. The situation had escalated to the level of the Federal Aviation Administration (FAA).
The FAA decided to scramble fighter jets from the Hawaii Air National Guard to shadow the unresponsive aircraft. It was an attempt to somehow get it back on course.
The North America Aerospace Defense Command (NORAD) also initiated procedures to address the emergency. It started scrambling F-22’s from the Hawaii Air National Guard to observe and intervene if needed.
But, as luck would have it, the two pilots woke just in time. They found themselves way off their predestined route and hastily resumed radio contact with the control tower.
They expressed shock and surprise at the deviation in their course. The wayward plane quickly corrected its course and resumed on its original path to Lihue.
In their statement to FAA, the pilots revealed that they had been suffering from fatigue. Extreme weariness had led them to unwittingly drift off to sleep while the plane continued to cruise on its own.
The pilots' confessions highlighted a significant issue plaguing the aviation industry: pilot fatigue. This occurrence brought to the forefront the challenges that pilots face due to extended working hours, irregular sleep schedules, and chronic fatigue.
The incident has triggered an important dialogue on the safety protocols in the aviation industry. It questioned the robustness and effectiveness of existing procedures in such an emergency situation.
The cargo plane's unplanned journey has also brought to light potential gaps in the systems meant to maintain communication between the ground control and the cockpit. Regardless of the causes, consequences of such lapses could be catastrophic.
Predictably, the incident has stirred up controversy. Industrial stakeholders, regulatory agencies, and policy makers are now rallying for reforms to address pilot fatigue and communication gaps.
The FAA, though quiet in the immediate aftermath, has pledged a detailed investigation into the incident. They are looking into the pilots’ confession about fatigue, the airline's safety policies, and the effectiveness of alerting systems.
The incident stirred a sense of urgency among authorities to review age-old practices in the aviation industry. They are now focusing on shoring up the protocols to prevent such off-course journeys in the future.
Ultimately, the cargo plane incident, alarming as it was, may end up being a wake-up call for the aviation industry to prioritize safety as it grapples with the after effects of the Covid-19 pandemic.
