The layout of the airplane at the busy airport in Canada increases the risk of collisions between aircraft and needs to be changed by a national air safety researcher.
The Transport Security Council made this recommendation to two more people as it published a report on 27 cases between 2012 and 2017, where passenger planes failed to stop on a line separating taxis from active runways at Toronto Pearson International Airport.
"The Transport Security Council has identified an alarming article from Pearson International," said CSB Chairman Kathy Fox at a news conference on Thursday. “We recommend the Greater Toronto Airports Authority [which runs the airport] to make a physical change in the taxi layout. ”
The TSB also advised Transport Canada and the United States Federal Aviation Administration (FAA) to request that pilot landing checks be delayed until they have completed all active runways to ensure that they keep their eyes on taxis. Finally, the TSB says that the Canadian air traffic controllers should give more orders to flight crew members to stop at the quay before another runway.
All Pearson incidents included the same five runways of the airport after the aircraft landed on the external runway and began to cross the internal runway in the southern part of the airport. Both runways are closely spaced, parallel and directly connected to the taxi with sharp curves, design features rarely found at major airports. The direct link increases the likelihood that the airplane crosses the live runway because its taxis are on the terminal, while the retention lines on the curves are not where the crew expects them.
These incidents were largely related to US regional airlines. In all cases, air traffic controllers were instructed to stop the pilots from sticking to another runway and confirmed the order, but continued to move forward before the air traffic controllers decided to stop again, said Ewan Tasker, TSB Regional Operations Operator investigating incidents in national aviation, rail , pipelines and maritime industries, and provides non-binding recommendations for hazard prevention. "The severity of these events ranges from moderate to pretty serious," he said. "Fortunately here, the last lines of defense dominated."
Mrs Fox said that no breakthrough in the Pearson runway caused a collision, but all pose a risk to public security. There are about 445 such accidents per year in Canada.
"Why is this happening?" Fox said. "After all, Pearson Airport traffic is tightly controlled and monitored. In addition to the specific instructions from air traffic controllers to stop and intercept other runways, flight crews receive signs of multiple lights, warning signs and colored lines on the ground. As a professional, highly qualified, experienced flight crew, do you miss all these instructions? And why is it so common? ”
Possible physical changes to the layout include the construction of a taxi between the runways or one that crosses the perimeter, or by changing the design and location of the taxis, Fox said to journalists.
Fox said that the TSB looked at 130 airports around the world, including the 60 largest US airports, and found Pearson to be the only one with enough space for an intermediate taxi between parallel runways, but it doesn't.
“GTAA ultimately decides which physical changes have been made. Until these changes are made, we want to see further improvements to increase the visibility of these short positions. Because much more needs to be done to allow all flight crew members to see and respond as needed, ”said Fox.
Transport Canada has 90 days to respond to the TSB report. The FAA and GTAA do not need to respond or act in response to the message.
In the statement, GTAA stated that it would review the recommendations of the TSB. The airport operator said that it has been working with carriers since 2013 to reduce such accidents and has improved taxis and runways that include new lighting systems and illuminated signs.
