![]() Status display showing Embraer (ACA1037) airborne at 50kt with the 777 (ACA606) on ground at 9kt ![]() Once the 777 had accelerated to 81kt, its speed exceeded that of the decelerating Embraer, and the reducing distance between them should have triggered an alert from the incursion monitor.īut since the monitor can only detect a departure conflict if the aircraft are identified as being on the ground, no alarm was generated. While this design logic had certain interoperability benefits, the inquiry says it provides “inaccurate” information to ground-surveillance systems.Įven though it never left the ground, the Embraer transmitted to the incursion monitor that it was airborne for 52s. This incursion monitor receives information on whether an aircraft is in the air, or on the ground, from a multi-sensor tracker in the airport’s surface-movement system – which, in turn, obtains the data from the aircraft’s transponder.īut the inquiry found that the Embraer 190’s avionics were designed to transmit an ‘in air’ status when airspeed exceeded 50kt – even if the aircraft was still on the ground. The runway was monitored by an incursion system, but the investigation states that its accuracy was compromised by aircraft design logic, with the result that it did not immediately detect the conflict. Pilots of the 777-300ER aborted take-off at 133kt after seeing the Embraer still on the runway While the controller heard the 777 crew read-back, neither the 777 crew nor the controller heard the Embraer pilots’ call. As a result, the 777 began its take-off roll while the Embraer was rapidly decelerating 5,000ft ahead. “The simultaneous radio transmissions went undetected,” it says. ![]() Having perceived the Embraer was close to rotation, and anticipated it would become airborne, the controller shifted his attention elsewhere and issued take-off clearance to the 777 crew.Ĭanada’s Transportation Safety Board says the 777 crew read back the clearance at the same time as the Embraer crew transmitted that they were rejecting their own take-off. Airline Business special: CEOs to watch in 2021Ĭanadian investigators have determined that a Boeing 777-300ER crew rejected take-off at high speed after seeing that a preceding aircraft, an Embraer 190, was still on the runway after conducting its own high-speed abort.įalse information about the air-ground status of both aircraft, each operated by Air Canada, along with an unfortunate simultaneous radio transmission to the control tower, meant the controller was unaware that the Embraer – having sustained a bird-strike – was aborting its take-off from Toronto’s runway 06L at 139kt.FlightGlobal Guide to Business Aviation Training and Safety 2021.EDGE: A new global force in aerospace and defence.Shell Aviation: What will it take to Decarbonise Aviation?.What does the future of aviation look like in 2022?.Guide to Business Aviation Training and Safety 2022.What will it take to Decarbonise Aviation?.Airline Business Covid-19 recovery tracker.The chosen route is certainly one of the most interesting as it features the wonderful destinations of Dubai & Hong Kong! This time we film the Boeing 777-200 Long Range Freighter and we're once again really lucky to have 3 sets of wonderful pilots who take their time and present this entire trip in complete details. Following the Boeing 737-300/400 film we're delighted that TNT invited us back to film one of their long haul operations.
