ADME 2.13 NUMBERING OF AIRCRAFT IN THE AERODROME TRAFFIC CIRCUIT

One of the reasons for the investigation of numbering of aircraft in the aerodrome traffic circuit was an incident in Israel, whereby the use of the term ‘number’ in radiotelephony was considered to be one of the contributory factors of this incident. After reviewing the relevant ICAO publications, IFATCA concludes that the use of ‘number’ in phraseology appears to be insufficiently supported by ICAO rules and guidelines. As a result, controllers world-wide use the term frequently, and often also refer to other phases of flight than the aerodrome traffic circuit. Besides this, ICAO does not provide the desired clarity when it comes to the ending of the aerodrome traffic circuit. For these reasons, Provisional Policy was adopted to provide the much needed clarity with the use of ‘number’.


IFATCA Provisional Policy is:

If ‘number’ is used in other than the aerodrome traffic circuit, i.e. for situational awareness, then the controller should use the phraseology

‘NUMBER … IN [approach, taxi] SEQUENCE’
