Clearances authorizing instrument approaches are issued on the basis that, if visual contact with the ground is made before the approach is completed, the entire approach procedure will be followed unless the pilot receives approval for a contact approach, is cleared for a visual approach, or cancels their IFR flight plan. вЂњCleared I-L-S Runway Three-Six Approach, glideslope unusable.вЂќ.вЂњCleared BRANCH ONE Arrival and (ILS/RNAV) Runway One-Three Approach.вЂќ.вЂњCleared (GPS/RNAV Z) Runway Two-Two Approach.вЂќ.вЂњCleared Localizer Back Course Runway One-Three Approach.вЂќ.вЂњCleared L-D-A Runway Three-Six Approach.вЂќ.вЂњCleared (V-O-R/I-L-S/Localizer) Approach.вЂќ.(When it is necessary to cancel a previously issued approach clearance).CANCEL APPROACH CLEARANCE (additional instructions as necessary).(When the title of the approach procedure contains вЂњor LOCвЂќ).(To authorize a pilot to execute an ILS or an LDA approach when the glideslope is out of service).CLEARED (ILS/LDA) APPROACH, GLIDESLOPE UNUSABLE.(Where more than one procedure is published on a single chart and a specific procedure is to be flown),.

CLEARED (specific procedure to be flown) APPROACH.

(To authorize a pilot to execute his/her choice of instrument approach),.

Controllers must not disapprove a pilot request to cold temperature compensate in conjunction with the issuance of an approach clearance.

Where adequate radar coverage exists, radar facilities may clear an aircraft to any fix 3 NM or more prior to the FAF, along the final approach course, at an intercept angle not greater than 30 degrees.

Where adequate radar coverage exists, radar facilities may vector aircraft to the final approach course in accordance with Paragraph 5-9-1, Vectors to Final Approach Course, and Paragraph 5-9-2, Final Approach Course Interception.

Standard instrument approach procedures (SIAP) must begin at an initial approach fix (IAF) or an intermediate fix (IF) if there is not an IAF.

An aircraft conducting an ILS or LDA approach must be advised at the time an approach clearance is issued when the glideslope is reported out of service, unless the title of the published approach procedure allows (for example, ILS or LOC Rwy 05).

If only one instrument approach of a particular type is published, the approach needs not be identified by the runway reference. Where more than one procedure is published on a single chart and a specific procedure is to be flown, amend the approach clearance to specify execution of the specific approach to be flown.

To require an aircraft to execute a particular instrument approach procedure, specify in the approach clearance the name of the approach as published on the approach chart.

Clear aircraft for вЂњstandardвЂќ or вЂњspecialвЂќ instrument approach procedures only.
