Provisions

Provisions Relating to the 2016 SID/STAR Procedures and Phraseology

It is essential that ATCOs and flight crews understand and use the correct, unabbreviated phraseology. Failure to do so may result in unnecessary communications, readback or hearback errors and unsafe pilot deviations.

 

The phraseologies are used to clear aircraft to follow published SID/STAR procedures and incorporate explicit level and speed instructions.

 

SID and STAR Phraseologies

 

 

 

 

To clear an aircraft to fly the published procedure's route, speeds and altitudes:

 

  • CLIMB VIA SID TO (level)

 

  • DESCEND VIA STAR TO (level)


For controllers and flight crews these phraseologies mean that:

1. The aircraft will climb/descend to the cleared level in accordance with published level restrictions;

2. The lateral profile of the procedure will be followed; and

3. The published speed restrictions or ATC-issued speed control instructions will be complied with. 

 

To remove speed or level restrictions on the published procedure:

 

  • CLIMB VIA SID TO (level), CANCEL SPEED RESTRICTION(S)

 

  • DECEND VIA STAR TO (level), CANCEL LEVEL RESTRICTION(S)

 

For controllers and flight crews these phraseologies mean that:


1. The lateral profile of the procedure will be followed;

2. Speed or level restrictions which have not been referred to will continue to apply.

 

To remove speed or level restrictions at a specific point(s) on the published procedure:

 

  • CLIMB VIA SID TO (level), CANCEL SPEED RESTRICTION(S) AT(point(s))

 

  • DECEND VIA STAR TO (level), CANCEL LEVEL RESTRICTION(S) AT(point(s))

    For controllers and flight crews these phraseologies mean that:

    1. The lateral profile of the procedure will be followed;

    2. Speed or level restrictions which have not been referred to will continue to apply.

 

To remove speed and level restrictions on the published procedure until the cleared level:

 

  • CLIMB UNRESTRICTED TO (level) or CLIMB TO (LEVEL), CANCEL LEVEL AND SPEED RESTRICTION(S):
  •  
  • DESCEND UNRESTRICTED TO (level) or DESCEND TO (level), CANCEL LEVEL AND SPEED RESTRICTION(S):

 For controllers and flight crews these phraseologies mean that:

 

  1. The lateral profile of the procedure will be followed;
  2. The restrictions above/below the cleared level are cancelled
  3. Speed restrictions that are associated with airspace still apply (i.e. speed not more than 250 knots below 10,000 ft.)

 

Variations to lateral profile of the SID/STAR:

 

There are instances in which aircraft may be issued clearances which take it off the SID/STAR published procedure. In situations where the aircraft is being vectored or cleared to a point that is not on the published procedure be aware of the following:

 

  1. All of the published speed and level restrictions of the procedure are canceled.
  2. The air traffic controller must reiterate the cleared level, provide speed and level restrictions as necessary and notify the pilot if it is expected the aircraft will be instructed to subsequently rejoin the published procedure.

 

Phraseology to return to the SID:

 

If advance notice of a future instruction to rejoin the SID was provided to the flight crew:

 

  • REJOIN SID [(SID designator)] [AT (waypoint)]

 

If advance notice of a future instruction to rejoin the SID was not provided to the flight crew:

 

  • REJOIN SID (SID designator) AT (waypoint)

 

For controllers and flight crews these phraseologies mean that:

 

  1.  Speed and level restrictions associated with the waypoint where the rejoin occurs, as well as those
    associated with all subsequent waypoints, must be complied with.

 

Phraseology to return to the STAR:

 

If advance notice of a future instruction to rejoin the STAR was provided to the flight crew:

 

  • REJOIN STAR [(STAR designator)] [AT (waypoint)]

 

If advance notice of a future instruction to rejoin the STAR was not provided to the flight crew:

 

  • REJOIN STAR (STAR designator) AT (waypoint)

 

For controllers and flight crews these phraseologies mean that:

Speed and level restrictions associated with the waypoint where the rejoin occurs, as well as those

associated with all subsequent waypoints, must be complied with.
