1.2.2 The instruction to report heading may be expanded to “report heading and level”.
1.2.3 When a controller has identified an aircraft he will inform the pilot, according to the
circumstances, of the following:
a) that the aircraft is identified, and
b) of the position of the aircraft.
The occasions when the above information will be passed are summarised in Table 1
below. Additionally, controllers may pass position information to aircraft whenever
they consider it necessary.
*When providing a Basic Service, a controller may identify an aircraft to facilitate co-
ordination or to assist in the provision of generic navigational assistance, but is not
required to inform the pilot that identification has taken place or to pass a position
report.
1.2.4 The pilot will be warned if identification is lost, or about to be lost, and appropriate
instructions given.
