Class Delta

Entering Class Delta airspace

Aircraft wishing to proceed into a Class Delta airspace must establish two communications with ATC controlling that airspace. If conditions do not allow for Class Delta services, instruct the aircraft to remain outside of the Class Delta airspace.

Once two-way communications are established the aircraft may enter the Class Delta airspace.

Example:
N312PD, Provo Tower, standby

If two-way communications are not established the aircraft may not enter the Class Delta airspace.

Example:
Aircraft calling Provo Tower, standby.

If two-way communications are established but conditions do not allow for Class Delta services, instruct the aircraft to remain outside of the Class Delta airspace.

Example:
N312PD, remain outside Delta airspace and standby.

Transitioning Class Delta airspace

Approve aircraft wanting to transition the Class Delta airspace and provide any additional restrictions as necessary.’

Example:
N312PD, transition approved.
N312PD, transition approved. Maintain VFR at 6,500.
N312PD, transition approved. Remain west of runway 18. Maintain VFR at 6,500.

Leaving Class Delta airspace

Aircraft that were not explicitly instructed to remain on frequency or ones that did not request flight following will switch to advisory once they leave your airspace and do not require approval to do so.

Aircraft receiving flight following shall be instructed to contact the appropriate radar controller.

Example:
N312PD, contact Salt Lake Approach, 124.3.

Aircraft that were instructed to remain on frequency will be approved to change frequencies when appropriate.

Example:
N312PD, frequency change approved.

Class Charlie

Entering Class Charlie airspace

Aircraft wishing to proceed into a Class Charlie airspace must establish two communications with ATC controlling that airspace and have a Mode C transponder. If conditions do not allow Class Charlie services, instruct the aircraft to remain outside of the Class Charlie airspace.

Once two-way communications are established, the aircraft may enter the Class Charlie airspace.

Example:
N312PD, Boise Tower, standby.

If two-way communications are not established the aircraft may not enter the Class Charlie airspace.

Example:
Aircraft calling Boise Tower, standby.

If two-way communications are established but conditions do not allow for Class Charlie services, instruct the aircraft to remain outside the Class Charlie airspace.

Example:
N312PD, remain outside charlie airspace and standby.

Transitioning Class Charlie airspace

Most aircraft transitioning Class Charlie airspace will do so with approach control. If the aircraft must transition with tower, provide any additional restrictions as necessary.

Example:
N312PD, maintain VFR at 4,500.
N312PD, remain north of Boise airport. Maintain VFR at 4,500.

Leaving Class Charlie airspace

Aircraft receiving flight following shall be instructed to contact the appropriate radar controller.

Example:
N312PD, contact Big Sky Approach, 119.6.

Aircraft shall be instructed to change to advisory frequency when they leave the Class Charlie airspace.

Example:
N312PD, frequency change approved.

Class Bravo

Entering Class Bravo airspace

Aircraft wishing to proceed into a Class Bravo airspace must establish two-way communications with ATC controlling that airspace, a Mode C transponder, and an explicit clearance authorizing the aircraft to enter Class Bravo airspace. If conditions do not allow for Class Bravo services, instruct the aircraft to remain outside of the Class Bravo airspace.

Once the explicit clearance to enter is provided, the aircraft may enter the Class Bravo airspace.

Example:
N312PD, cleared to enter Bravo airspace.

Provide any additional instructions as necessary.

Example:
N312PD, cleared to enter Bravo airspace. Maintain 6,500 while in Bravo airspace.
N312PD, cleared to enter Bravo airspace via I-15 northbound transition. Maintain 6,000 while in Bravo airspace.
N312PD, cleared to enter Bravo airspace. Cleared as requested.

If conditions do not allow for Class Bravo services, instruct the aircraft to remain outside of the Class Bravo airspace.

Example:
N312PD, remain outside Bravo airspace.

Transitioning Class Bravo airspace

Most aircraft transitioning Class Bravo airspace will do so with approach control. If the aircraft must transition with tower, clear the aircraft through the Class Bravo airspace.

Example:
N312PD, cleared through Bravo airspace.

Provide any additional instructions as necessary.

Example:
N312PD, cleared though Bravo airspace. Cleared as requested.

Leaving Class Bravo airspace

Aircraft intending to depart the Class Bravo airspace will be cleared out of the Bravo airspace. Provide any additional instructions as necessary.

Example:
N312PD, cleared out of Bravo airspace.
N312PD, cleared out of Bravo airspace via I-15 southbound. Maintain 6,500 while in Bravo airspace.

Inform aircraft when they are leaving Class Bravo airspace.

Example:
N312PD, leaving Salt Lake City Bravo airspace.
N312PD, leaving Salt Lake City Bravo airspace. Resume own navigation. Remain this frequency for traffic advisories.
”N312PD, leaving Salt Lake City Bravo airspace. Resume own navigation. Squawk 1200. Frequency change approved.”
