Ground Controlled Approach (GCA) - Cont'd

SNFO/SWSO VOICE COMMUNICATIONS

CHAPTER THREE

Advise when at Decision Height (DH) or Missed Approach Point (MAP).

Advise when over landing threshold (end of runway).

The final controller receives the clearance to land from Tower. The final controller will then

issue this clearance to you on your descent (normally 2-3 miles from touchdown). Even though

he has previously instructed you to not acknowledge further transmissions, this is an exception

and you will repeat the landing clearance.

Example

FINAL CONTROLLER:

"BUCK 722, winds 080 at 15, cleared to land

runway 7 Right."

SNFO/SWSO:

"BUCK 722, cleared to land 7 Right."

Be alert for the missed approach instructions or climbout instructions if doing multiple

approaches. The controller may issue different missed approach instructions from those

published on your approach plate. Remember the missed approach instructions on the approach

plate are for the radio instrument approach, NOT the GCA. The GCA missed approach

instructions are issued prior to beginning your descent. Altitudes and headings should be read

back for mutual understanding. When the weather is VMC, controllers may not issue missed

approach instructions when you intend to land; however, expect climbout instructions if you plan

to execute a touch and go.

Example

CONTROLLER:

"KATT 813, climbout instructions are runway

heading to 800 feet, 2 DME past the TACAN,

turn right 180, climb and maintain1500."

SNFO/SWSO:

"KATT 813, runway heading to 800, at 2 DME,

right 180, then climb and maintain 1500."

The controller may also issue Lost Communication Instructions, especially if the weather is not

VMC.

Example

CONTROLLER:

"If no transmissions received for 1 minute in the

pattern or 5 (PAR Approach) seconds on final,

attempt to contact tower on 265.8 and proceed

VFR. If unable to proceed VFR, intercept the

TACAN final for runway 7R, maintain 1500 until

the FAF."
