Ground and Tower practices need to be safely integrated
19 Sep 2022
On 14 November 2019, a Boeing 737 was instructed to stop its takeoff whilst still at low speed when the controller saw snow clearance vehicles entering the runway ahead. The Investigation found that the vehicle group had been cleared to enter the active runway by the ground controller without any coordination with the tower controller and that only the monitoring of surface movement radar and the external environment visually had removed the risk of a more serious consequence arising from the incursion. The airport operator’s snow response plan was not specific to their airport and consequently of limited practical value.
