INSTRUMENT FLIGHT RULES WORKBOOK
Automatic Terminal Information Service (ATIS) is a transcribed broadcast service available at
most large airports. ATIS provides essential, but routine terminal information such as ceilings,
visibility, altimeter setting, wind, and duty runway, etc. On initial contact with Approach
Control, pilots should notify the controller that they have received the broadcast by code letter of
"... WITH INFORMATION DELTA."
Approach Control - Radar Environment
The pilot's initial contact with Approach Control in a radar environment would be (name)
APPROACH (aircraft identification), (altitude), (ATIS information received), REQUEST.
PILOT: "MOBILE APPROACH, NAVY 6E432, 8000 WITH INFORMATION (letter),
MOBILE APP: "NAVY 6E432, MOBILE APPROACH, MOBILE ALTIMETER IS XX.XX,
SAY YOUR REQUEST."
PILOT: "APPROACH , NAVY 6E432, REQUEST VOR-ALPHA APPROACH TO MOBILE
MOBILE APP: "NAVY 6E432, CLEARED DIRECT SEMMES, CLEARED FOR THE VOR-
Passing over Semmes, you would start the VOR-Alpha approach and make the mandatory report
PILOT: "MOBILE APPROACH, NAVY 6E432, LEAVING 8000 FOR THE APPROACH."
You do not need to say "leaving 8000 for 1800" because the
controller knows you are descending to the altitude published in
the approach plates.
In the vicinity of the Final Approach Fix, Mobile Approach will have you contact Mobile tower
for clearance to land. Example:
MOBILE APP: "NAVY 6E432, CONTACT MOBILE TOWER, 239.0"
PILOT: "MOBILE APPROACH NAVY 6E432, SWITCHING TO MOBILE TOWER, 239.0"
