approach course, instruct the pilot NOT to acknowledge further transmissions.
PHRASEOLOGY: DO NOT ACKNOWLEDGE FURTHER TRANSMISSIONS.
f. Approach Course Guidance
(1) Issue course guidance, inform the pilot when the aircraft is on course, and frequently inform
the pilot of any deviation from course.
PHRASEOLOGY: TURN LEFT HEADING ZERO-FIVE-FIVE, SLIGHTLY RIGHT OF COURSE.
(2) Issue trend information as required to indicate the target position with respect to an extended
runway centerline. Also issue trend information to describe target movement as appropriate corrections
PHRASEOLOGY: SLIGHTLY RIGHT OF COURSE, CORRECTING SLOWLY.
(1) After a turn onto the final approach has been made and before the aircraft reaches the
approach gate, instruct the pilot to make half-standard-rate turns.
PHRASEOLOGY: MAKE HALF-STANDARD-RATE TURNS.
(2) This procedure enables the controller to issue smooth control instructions without a tendency
to overcontrol or zigzag down the final approach course. Remember, it takes twice as much time to turn
a specified number of degrees. Instead of the aircraft turning 3 degrees per second, it will only be
turning 1 1/2 degrees per second.
h. Request and Issue Tower Clearance.
(1) When a pilot is on a final approach to an airport served by a tower, obtain a clearance to land
(or a touch and go) or make a low approach. Issue the clearance and surface wind to the pilot.
WINDS ZERO-EIGHT-ZERO AT SIX; CLEARED TO LAND.
(2) If the clearance is not obtained or is cancelled, inform the pilot and issue alternative
PHRASEOLOGY: TOWER CLEARANCE CANCELLED; EXECUTE MISSED APPROACH,
