Runway in use
Temperature (pressure altitude)
The following is an example of ATIS broadcast:
"This is Navy Pensacola information ALPHA, time 1200Z. Sherman weather 1000
scattered, 25,000 broken, visibility 7, wind 060 at 10, altimeter 29.94, pressure altitude
+100, runway temperature 17, duty runway 7 right, approach in use PAR runway 7 right.
Inform ground, Tower, or approach on initial contact that you have received information
3. You will be responsible for copying the ATIS information prior to contacting ground (on
departures) or approach control (for arrivals). A phonetic letter (alpha, bravo, etc.) identifies
each broadcast. ATIS broadcasts will normally be updated five minutes past the hour or if
weather or field conditions change. The ATIS tape is continuous and can be listened to again in
case pertinent information is missed the first time. After recording all applicable information,
switch to the next frequency automatically. Inform ground or approach control upon initial
contact that you have received the ATIS information. If you forget to report that you have
current ATIS, the controller will read information, wasting valuable frequency time.
4. If the service is not available, the pertinent information will be provided by ground or
approach when you check in with "negative ATIS" or "negative numbers."
203. CLEARANCE DELIVERY
1. At airports where a control tower is in operation, ATC clearances are normally relayed to
pilots of departing aircraft by ground control. At many busy airports such as Sherman Field,
"clearance delivery" has been established on a separate radio frequency. Clearance delivery does
not have any control over the movement of aircraft.
At airports where there is not a Clearance Delivery frequency
listed in publications, Ground Control shall be used to obtain
2. Tower, ground, and clearance delivery are all physically located in the control tower.
Although they perform three separate functions, they work hand in hand to ensure the safe, and
