SNFO/SWSO VOICE COMMUNICATIONS
At some "out and in" fields you may be instructed to switch to departure during the "cleared for
takeoff call". Read back that you will remain on Tower frequency during takeoff (in case of an
emergency on deck or an aborted takeoff). Switch to departure only when comfortably airborne
(remember aviate, navigate, communicate). If Tower does not tell you to switch during the
"cleared for takeoff call," do not switch until directed to switch by the tower controller.
"BUCK 714, winds 240 at 12, change to
departure, cleared for takeoff runway 22."
"BUCK 714 cleared for takeoff runway 22,
switching when airborne."
The call to departure has changed from VFR procedures since you have an altitude clearance
limit which must be reported on check-in. Report the altitude passing and the altitude cleared to.
Do not report the DP restriction altitude or expected altitude.
"Pensacola Departure, BUCK 713, airborne,
passing 800 for 4000."
306. RADAR ENVIRONMENT
Flights along airways and direct point-to-point flights within the continental United States are
generally conducted in a radar environment. This means the aircraft's transponder code has been
positively identified on the controller's radar display and he/she can track your progress through
the ARTCC system.
During your flights, you will be either in a radar or non-radar environment. ATC will inform
Your aircraft is initially identified in the ATC system
Radar service has been terminated or radar contact is lost.
Radar identification is re-established.
In the United States you will be in radar contact almost always. After you make the airborne call
to Departure Control, he/she should respond:
"BUCK 713, Departure Control, radar contact."
