4.2.3. Aerodrome switching/merging/transferring/closing under multiple mode of operation

• ED Decision 2023/005/R found in: GM Remote Aerodrome Air Traffic Services (Jan 2026)

##### 4.2.3. Aerodrome switching/merging/transferring/closing under multiple mode of operation *ED Decision 2023/005/R* The multiple mode of operation may include scenarios where the ATCO/AFISO would change service provision between aerodromes on a flexible basis. This may include the following possibilities: — switching: changing service provision for one (or several) aerodrome(s) to another aerodrome (e.g. if providing service to aerodromes A & B, change service provision to aerodromes A & C); — merging: adding aerodromes to be provided with service (e.g. if providing service to aerodromes A & B, change service provision to aerodromes A, B & C); and — closing or transferring service provision for one or several aerodromes (e.g. if providing service to aerodromes A, B & C, change service to aerodromes A & B). This may also include the possibility of changing from a single mode of operation to a multiple mode of operation environment, or vice versa, by adding or closing/transferring aerodromes in the RTM (e.g. if providing service to aerodrome A, change service provision to aerodrome A & B, or vice versa). Switching/merging/transferring/closing of aerodromes should only be done when circumstances so allow. The ATS provider should establish the related procedures and conditions to adequately manage the operational circumstances (e.g. ‘when and how’) for any such implemented scenario. All mechanisms implemented should be validated, approved by the competent authority as part of the change to the functional system and documented in the operations manual (as specified by Regulation (EU) 2017/373 [4], ATM/ANS.OR.B.035 ‘Operations manuals’). Furthermore, human factors considerations related to switching are detailed in the end of Section [6.3.1](#_DxCrossRefBm1764263602).
