GM1 to AMC1 ATS.TR.235(b)(2) ATC clearances

SPECIFICATION OF CLEARANCE LIMIT

(a)When prior coordination has been effected with units under whose control the aircraft will subsequently come, or if there is reasonable assurance that it can be effected a reasonable time prior to their assumption of control, the clearance limit should be the destination aerodrome or, if not practicable, an appropriate intermediate point, and coordination should be expedited so that a clearance to the destination aerodrome may be issued as soon as possible.

(b)If an aircraft has been cleared to an intermediate point in adjacent controlled airspace, the appropriate air traffic control unit will then be responsible for issuing, as soon as practicable, an amended clearance to the destination aerodrome.

(c)When the destination aerodrome is outside controlled airspace, the air traffic control unit responsible for the last controlled airspace through which an aircraft will pass should issue the appropriate clearance for flight to the limit of that controlled airspace.
