Arrival Procedures

b. Radar Services. These services are provided for

each simultaneous independent approach.

1. During turn on to parallel final approach,

aircraft are normally provided 3 miles radar

separation or a minimum of 1,000 feet vertical

separation. The assigned altitude must be maintained

until intercepting the glidepath, unless cleared

otherwise by ATC. Aircraft will not be vectored to

intercept the final approach course at an angle greater

than thirty degrees. 

NOTE−

Some simultaneous operations permit the aircraft to track

an RNAV course beginning on downwind and continuing

in a turn to intercept the final approach course. In this case,

separation with the aircraft on the adjacent final approach

course is provided by the monitor controller with reference

to an NTZ.

2. The final monitor controller will have the

capability of overriding the tower controller on the

tower frequency.

3. Pilots will be instructed to contact the tower

frequency prior to the point where NTZ monitoring

begins.

4. Aircraft observed to overshoot the turn−on or

to continue on a track which will penetrate the NTZ

will be instructed to return to the correct final

approach course immediately. The final monitor

controller may cancel the approach clearance, and

issue missed approach or other instructions to the

deviating aircraft.

PHRASEOLOGY−

“(Aircraft call sign) YOU HAVE CROSSED THE FINAL

APPROACH COURSE. TURN (left/right)

IMMEDIATELY AND RETURN TO THE FINAL

APPROACH COURSE,”

or

“(aircraft call sign) TURN (left/right) AND RETURN TO

THE FINAL APPROACH COURSE.”

5. If a deviating aircraft fails to respond to such

instructions or is observed penetrating the NTZ, the

aircraft on the adjacent final approach course (if

threatened), will be issued a breakout instruction.

PHRASEOLOGY−

“TRAFFIC ALERT (aircraft call sign) TURN (left/right)

IMMEDIATELY HEADING (degrees), (climb/descend)

AND MAINTAIN (altitude).”

6. Radar monitoring will automatically be

terminated when visual separation is applied, the

aircraft reports the approach lights or runway in sight,

or the aircraft is 1 NM or less from the runway

threshold. Final monitor controllers will not advise

pilots when radar monitoring is terminated.

NOTE−

Simultaneous independent approaches conducted to

runways spaced greater than 9,000 feet (or 9,200’ at

airports above 5,000’) do not require an NTZ. However,

from a pilot’s perspective, the same alerts relative to

deviating aircraft will be provided by ATC as are provided

when an NTZ is being monitored. Pilots may not be aware

as to whether or not an NTZ is being monitored.
