ISMS partners jointly investigated a safety incident in 2018, which happened between a towed aircraft and a marshaller in the field. As a result, Schiphol and its partners have already taken a number of further measures, such as tightening up the procedure, to reduce the risks of marshalled towing. The tow drivers are trained and qualified for the new 2021 standard. The manual has been changed with a clear instruction for tow drivers on the operational procedure. We have also reduced the need to marshal towing movements, thus reducing the risk of safety incidents with marshalled tows.
