5-9-1 Vectors to Final Approach Course
Except as provided in paragraph 7-4-2, vector arriving aircraft
to intercept the final approach course:
a. At least 2 miles outside the approach gate unless one of the
following exists:
1. When the reported ceiling is at least 500 feet above the
MVA/MIA and the visibility is at least 3 miles (report may be a PIREP if
no weather is reported for the airport), aircraft may be vectored to intercept
the final approach course closer than 2 miles outside the approach gate
but no closer than the approach gate.
2. If specifically requested by the pilot, aircraft may be vectored
to intercept the final approach course inside the approach gate but no
closer than the final approach fix.
b. For a precision approach, at an altitude not above the glideslope/glidepath
or below the minimum glideslope intercept altitude specified on the approach
procedure chart.
c. For a nonprecision approach, at an altitude which will allow
descent in accordance with the published procedure.
NOTE -
A pilot request for an "evaluation approach," or a "coupled approach,"
or use of a similar term, indicates he desires the application of subparagraphs
a and b.
d. EN ROUTE: The following provisions are required before an aircraft
may be vectored to the final approach course:
1. The approach gate and a line (solid or broken), depicting
the final approach course - starting at or passing through the approach
gate and extending away from the airport, be displayed on the radar scope;
for a precision approach, the line length shall extend at least the maximum
range of the localizer; for a nonprecision approach, the line length shall
extend at least 10NM outside the approach gate, and:
2. The maximum range selected on the PVD is 150 NM, or;
3. An adjacent PVD is set at 125 NM or less, configured for
the approach in use, and is utilized for the vector to the final approach
course.
4. If unable to comply with d1, d2, or d3 above, issue the clearance
in accordance with paragraph 4-8-1 of this order.

FAAO 7110.65, Approach Clearance, paragraph 4-8-1.
FAAO 7110.65, Final Approach Course Intersection, paragraph 5-9-2.
5-9-2 Final Approach Course Interception
a. Assign headings that will permit final approach course interception on a track that does not exceed the interception angles specified in the Table 5-9-1.
Table 5-9-1
Approach Course Interception Angle
---------------------------------------------------------------------
Key:
Distance from interception point to

angle
---------------------------------------------------------------------
Less than 2 miles or Triple Simultaneous ILS/MLS Approaches
in use:
20 degrees
2 miles or more:
30 degrees (45 degrees for helicopters)
---------------------------------------------------------------------
b. If deviations from the final approach course are observed after
initial course interception, apply the following:
1. Outside the approach gate: Apply procedures in accordance
with subparagraph a, if necessary, vector the aircraft for another approach.
2. Inside the approach gate: Inform the pilot of the aircraft's
position and ask intentions.
PHRASEOLOGY -
(Ident) (distance) MILE(S) FROM THE AIRPORT, (distance) MILE(S) RIGHT/LEFT
OF COURSE, SAY
INTENTIONS.
NOTE -
The intent is to provide for a trackcourse intercept angle judged by
the controller to be no greater than specified by this procedure.
REFERENCE -
FAAO 7110.65, Chapter 5, Section 9 and Section 10.
c. EN ROUTE: When using a radar scope range above 125 NM, the controller shall solicit and receive a pilot report that the aircraft is established on the final approach course. If the pilot has not reported established by the final approach gate, inform the pilot of his observed position and ask intentions.
{New-98-3 Revised February 26, 1998}
NOTE -
It may be difficult to accurately determine small distances
when using very large range settings.
5-9-3 Vectors Across Final Approach Course
Inform the aircraft whenever a vector will take it across the final approach course and state the reason for such action.
NOTE -
In the event you are unable to so inform the aircraft, the pilot is
not expected to turn inbound on the final approach course unless approach
clearance has been issued.
PHRASEOLOGY -
EXPECT VECTORS ACROSS FINAL FOR (purpose).
EXAMPLE -
"Expect vectors across final for spacing."
REFERENCE -
FAAO 7110.65, Final Approach Course Interception, paragraph 5-9-2.
Issue all of the following to an aircraft before it reaches the
approach gate:
a. Position relative to a fix on the final approach course. If
none is portrayed on the radar display or if none is prescribed in the
procedure, issue position information relative to the navigation aid which
provides final approach guidance or relative to the airport.
b. Vector to intercept the final approach course if required.
c. Approach clearance except when conducting a radar approach.
Issue approach clearance only after the aircraft is:
1. Established on a segment of a published route or instrument
approach procedure, or (See Figure 5-9-1 Example 1.)
2. Assigned an altitude to maintain until the aircraft is established
on a segment of a published route or instrument approach procedure. (See
Figure 5-9-2 through 5-9-4).

EXAMPLE -
1 - Aircraft 1 was vectored to the final approach course but clearance
was withheld. It is now at 4,000 feet and established on a segment of the
instrument approach procedure. "Seven miles from X-ray. Cleared ILS Runway
Three Six Approach." (See Figure 5-9-1)
2 - Aircraft 2 is being vectored to a published segment of the final
approach course, 4 miles from Lima at 2,000 feet. The MVA for this area
is 2,000 feet. "Four miles from Lima. Turn right heading three four zero.
Maintain two thousand until established on the localizer. Cleared ILS Runway
Three Six Approach." (See Figure 5-9-1)
3 - Aircraft 3 is being vectored to intercept the final approach course
beyond the approach segments, 5 miles from Alpha at 5,000 feet. The MVA
for this area is 4,000 feet. "Five miles from Alpha. Turn right heading
three three zero. Cross Alpha at or above four thousand. Cleared ILS Runway
Three Six Approach." (See Figure 5-9-1)
4 - Aircraft 4 is established on the final approach course beyond the
approach segments, 8 miles from Alpha at 6,000 feet. The MVA for this area
is 4,000 feet. "Eight miles from Alpha. Cross Alpha at or above four thousand.
Cleared ILS Runway Three Six Approach." (See Figure 5-9-1)
![]() |
EXAMPLE -
The aircraft is being vectored to a published segment of the MLS final
approach course, 3 miles from Alpha at 4,000 feet. The MVA for this area
is 4,000 feet. "Three miles from Alpha. Turn left heading two one zero.
Maintain four thousand until established on the azimuth course. Cleared
MLS Runway One Eight Approach." (See Figure 5-9-2)
![]() |
EXAMPLE -
The aircraft is en route to Delta Waypoint at 6,000 feet. The MVA for
this area is 4,000 feet. "Cross Delta at or above four thousand. Cleared
MLS Runway One Eight Approach." (See Figure 5-9-3)
![]() |
EXAMPLE -
The aircraft is being vectored to an MLS curved approach, 3 miles from
X-ray at 3,000 feet. "Three miles from X-ray. Turn right heading three
three zero. Maintain three thousand until established on the azimuth course.
Cleared MLS Runway One Eight Approach." (See Figure 5-9-4)
NOTE -
1 - The altitude assigned must assure IFR obstruction clearance from
the point at which the approach clearance is issued until established on
a segment of a published route or instrument approach procedure.
2 - If the altitude assignment is VFR on top, it is conceivable that
the pilot may elect to remain high until arrival over the final approach
fix which may require the pilot to circle to descend so as to cross the
final approach fix at an altitude that would permit landing.
d. Instructions to do one of the following:
NOTE -
The principal purpose of this paragraph is to ensure that frequency
changes are made prior to passing the final approach fix. However, at times
it will be desirable to retain an aircraft on the approach control frequency
to provide a single frequency approach or other radar services. When this
occurs, it will be necessary to relay tower clearances or instructions
to preclude changing frequencies prior to landing or approach termination.
1. Monitor local control frequency, reporting to the tower when
over the approach fix.
2. Contact the tower on local control frequency.
REFERENCE -
FAAO 7110.65, Communications Release, paragraph 4-8-8.
3. Contact the final controller on the appropriate frequency if radar service will be provided on final on a different frequency.
REFERENCE -
FAAO 7110.65, Final Controller Changeover, paragraph 5-10-8.
4. When radar is used to establish the final approach fix, inform the pilot that after being advised that he is over the fix he is to contact the tower on local control frequency.
EXAMPLE -
"Three miles from final approach fix. Turn left heading zero one zero.
Maintain two thousand until established on the localizer. Cleared ILS Runway
Three Six Approach. I will advise when over the fix."
"Over final approach fix. Contact tower one one eight point one."
NOTE -
ARSR may be used for establishment of initial approach and intermediate
approach fixes only. ASR must be used to establish the final approach fix.

{New-98-3 Added February 26, 1998}
e. Where a Terminal Arrival Area (TAA) has been established to support RNAV approaches, inform the aircraft of its position relative to the appropriate IAF and issue the approach clearance. (See Figure 5-9-5.)
{New-98-3 Added February 26, 1998}
EXAMPLE -
1 - Aircraft 1: The aircraft is in the straight in area of the
TAA. "Seven miles from CENTR, Cleared R-NAV
Runway One Eight Approach."
2 - Aircraft 2: The aircraft is in the left base area of the
TAA. "Fifteen miles from LEFTT, Cleared GPS Runway
One Eight Approach."
3 - Aircraft 3: The aircraft is in the right base area of the
TAA. "Four miles from WRITE, Cleared FMS Runway
One Eight Approach."
5-9-5 Approach Separation Responsibility
a. The radar controller performing the approach control function is responsible for separation of radar arrivals unless visual separation is provided by the tower, or a letter of agreement/facility directive authorizes otherwise. Radar final controllers ensure that established separation is maintained between aircraft under their control and other aircraft established on the same final approach course.
NOTE -
The radar controller may be a controller in an ARTCC, a terminal facility,
or a tower controller when authorized to perform the approach control function
in a terminal area.

b. When timed approaches are being conducted, the radar controller
shall maintain the radar separation specified in paragraph
6-7-5 until the aircraft is observed to have passed the final approach
fix inbound (nonprecision approaches) or the OM or the fix used in lieu
of the outer marker (precision approaches) and is within 5 miles of the
runway on the final approach course or until visual separation can be provided
by the tower.

b. The following conditions are required when applying the minimum
radar separation on adjacent localizer/azimuth courses allowed in subparagraph
a:
1. Apply this separation standard only after aircraft are established
on the parallel final approach course.
2. Straight-in-landings will be made.
3. Missed approach procedures do not conflict.
4. Aircraft are informed that approaches to both runways are
in use. This information may be provided through the ATIS.

NOTE -
1 - During triple parallel approaches, no two aircraft will be assigned
the same altitude during turn-on. All three aircraft will be assigned altitudes
which differ by a minimum of 1,000 feet. Example: 3,000, 4,000, 5,000;

from penetrating the NTZ.
6. Monitor all approaches regardless of weather. Monitor local
control frequency to receive any aircraft transmission. Issue control instructions
as necessary to ensure aircraft do not enter the NTZ.
NOTE -
1 - Separate monitor controllers, each with transmit/receive and override
capability on the local control frequency, shall ensure aircraft do not
penetrate the depicted NTZ. Facility directives shall delineate responsibility
for providing the minimum applicable longitudinal separation between aircraft
on the same final approach course.
2 - The aircraft is considered the center of the primary radar return
for that aircraft, or, if an FMA or other color final monitor aid is used,
the center of the digitized target of that aircraft, for the purposes of

controllers:
1. Instruct the aircraft to return to the correct final approach
course when aircraft are observed to the turn-on or to continue on a track
which will penetrate the NTZ.
PHRASEOLOGY -
YOU HAVE CROSSED THE FINAL APPROACH COURSE. TURN (left/right) IMMEDIATELY
AND RETURN TO LOCALIZER/AZIMUTH COURSE,
or
TURN (left/right) AND RETURN TO THE LOCALIZER/AZIMUTH COURSE.

simultaneous ILS, MLS, or ILS and MLS approaches are being conducted to
parallel runways. Factors include but are not limited to wind direction/velocity,
wind-shear alerts/reports, severe weather activity, etc. Closely monitor
weather activity that could impact the final approach course. Weather conditions
in the vicinity of the final approach course may dictate a change of approach
in use.
