Automatic Terminal Information Service (ATIS)

T-45C TS INav-01

Review of FLIP and FAA Publications

Automatic Terminal Information Service (ATIS): The continuous broadcast of routine, but essential, non-

control information, such as weather, altimeter,

runway in use, etc. Absence of a ceiling and

visibility indicates that weather of 5,000 ft ceiling

and 5-mile visibility or better exists. The primary

purpose of ATIS is to reduce frequency

congestion on Ground Control and Approach

Control frequencies.

NOTE: The pilot statement “Have the Numbers”

does not indicate receipt of ATIS. Inform

Ground Control for taxi or Approach Control on

arrival you have “Information Alpha, Bravo, etc.”

from the ATIS broadcast.

Tie-In Flight Service Station: A Tie-In Flight

Service Station is tied-in by direct telephone line

(DL) to the Base Operations Dispatcher. It

provides services to the airport such as relaying flight plans to ARTCC, relaying clearances back to the

airport, providing NOTAM services, etc. It may or may not be located at the airport. All Flight Service

Stations monitor 255.4 and UHF/VHF guard frequencies; the call sign is “RADIO.”

EXAMPLE: San Angelo Radio

Approach Control: Approach Control facilities and their related function of Departure Control are

responsible for coordinating with Air Route Traffic Control Centers and Airport Traffic Control Towers for

the control of IFR traffic between the en route structure and the airport. Absence of a separate name

indicates the same name as the airport. If not under ATC control, contact Approach Control on the

designated frequency for practice approaches, Special VFR, etc.

In some high density areas, specific Approach Control frequencies will be footnoted for use according to

the geographical sector in which your aircraft is located, not according to heading.
