## GM1 to AMC2 ATS.TR.155(c)(3) ATS surveillance services

VECTORING TO PILOT-INTERPRETED FINAL APPROACH AIDS

(a) The air traffic controller should issue the clearance for the approach prior to the time the aircraft reports are established unless circumstances preclude the issuance of the clearance at such time. Vectoring will normally terminate at the time the aircraft leaves the last assigned heading to intercept the final approach track.

(b) When clearance for the approach is issued, the aircraft is expected to maintain the last assigned level until intercepting the specified or nominal glide path of the approach procedure. If the air traffic controller requires an aircraft to intercept the glide path at a level other than a level flight segment depicted on the instrument approach chart, the air traffic controller should instruct the pilot to maintain the particular level until established on the glide path.

(c) The approach air traffic controller is normally responsible for maintaining separation based on ATS surveillance systems between succeeding aircraft on the same final approach, except that the responsibility may be transferred to the aerodrome air traffic controller in accordance with procedures prescribed by the air traffic services provider, and provided an ATS surveillance system is available to the aerodrome air traffic controller.
