1.3 Flights Joining Airways
1.3.1 Aircraft requiring to join an airway should make their request to the appropriate ATSU.
Where no flight plan has been filed, the request should include the filing of an airborne
flight plan (see Chapter 3). Where a flight plan has already been filed an abbreviated
call may be made.
1.3.2 Because of the prevailing traffic situation, a joining clearance may not be issued
immediately. Where it is not practicable to provide an expected clearance time, e.g.
where the instruction 'remain outside controlled airspace' is used by a ground station
other than the controlling authority for the relevant controlled airspace, the time check
and expected clearance time may be omitted.
1.3.3 In the event that the requested flight level is already occupied the controller will offer
an alternative.
1.4 Flights Leaving Airways
1.4.1 Flights leaving controlled airspace will normally be given a specific point at which to
leave, together with any other relevant instructions necessary to ensure separation.
