SNFO/SWSO VOICE COMMUNICATIONS
to the pilot. Since a radar approach is predicated upon voice instructions, repeat all headings,
altitudes and altimeter settings. Keep transmissions brief and specific.
Your aircraft will be vectored into the GCA pattern sequenced with other aircraft. As you near
the final approach course on a GCA approach (approximately 8 miles from touchdown), you will
be handed off to your final controller. He will contact you by saying:
"KATT 832, this is your final controller, wheels
should be down, how do you read?"
1. You should acknowledge with your call sign, how well you read his transmission, your
gear status, and intentions.
"KATT 832, loud and clear, gear down and
locked, touch and go."
The controller will issue small heading corrections and later tell you to begin your descent
(about 5-6 miles out). In addition, mileage calls will be given every mile. Repeat all required
information (headings, altimeters, etc.) until told "Do not acknowledge further transmissions."
Notice from Appendix C that on final you may omit your aircraft call sign in order to keep your
responses brief. This is only because you are on a GCA discrete frequency.
Your job is to continue monitoring the approach (altitude, course control, airspeed, etc.), as the
controller will now begin to issue precision glideslope and course information in a running
"Approaching glidepath, begin descent. On glidepath. Four miles, going slightly above
glidepath. Three miles, drifting slightly left of course, turn right heading 062. 062
assigned heading. Coming down and on glideslope, etc..."
This flow of information from controller to aircrew will continue until touchdown. After
reaching the DH/MAP, all GCA information is advisory only. During your GCA, the controller
Issue missed approach instructions (not normally issued in VMC conditions).
Advise you that your landing gear should be down and locked.
Clear you to land.
Issue a five second comm break for any questions/comments from the pilot.
