5.13.1.1 Handling of abnormal and emergency situations in multiple mode of operation

The ATS provider should put in place procedures and contingency plans that clearly define how to deal with unexpected or unusual events, such as an emergency at one of the aerodromes significantly increasing ATCO/AFISO workload and affecting their ability to continue to provide ATS to all aerodromes under their responsibility. Such procedures and situations require adequate and recurrent training. Each application for multiple mode of operation will require careful consideration for potentially exacerbated emergency situations and therefore the potential exists for enhanced training and mitigations. Accordingly, the following is a non-exhaustive list of actions the ATCO/AFISO could undertake to support the best possible management of an abnormal or emergency situation: Temporarily delay or stop traffic at the other aerodrome(s). Although AFISOs cannot exercise control of traffic, an AFISO could impose delays or other actions via coordination with other/adjacent ATS units and/or the aerodrome operator. Split aerodromes in order to isolate the aerodrome with the abnormal/emergency situation on an RTM dealing with only this issue. Request well-timed support of another qualified ATCO/AFISO, in order to be able to continue the provision of ATS for all aerodromes under the responsibility of the same RTM.
