GM1 SERA.11010 Strayed or unidentified aircraft
CAA ORS9 Decision No. 1
GENERAL
(a) An aircraft may be considered, at the same time, as a ‘strayed aircraft’ by one unit and as an ‘unidentified aircraft’ by another unit. This possibility should be taken into account when complying with the provisions of SERA.11010(a)(1)(iii) and SERA.11010(b)(2) and (b)(3).
(b) Navigational assistance by an air traffic services unit is particularly important if the unit becomes aware of an aircraft straying, or about to stray, into an area where there is a risk of interception or other hazard to its safety.
