5-12-1. GLIDEPATH NOTIFICATION
Inform the aircraft when it is approaching glidepath
(approximately 10 to 30 seconds before final
5-12-2. DECISION HEIGHT (DH)
Provide the DH to any pilot who requests it.
DECISION HEIGHT (number of feet).
5-12-3. DESCENT INSTRUCTION
When an aircraft reaches the point where final
descent is to start, instruct it to begin descent.
5-12-4. GLIDEPATH AND COURSE
a. Issue course guidance and inform the aircraft
when it is on glidepath and on course, and frequently
inform the aircraft of any deviation from glidepath or
course. Transmissions with aircraft on precision final
approach should occur approximately every
SLIGHTLY/WELL ABOVE/BELOW GLIDEPATH.
SLIGHTLY/WELL LEFT/RIGHT OF COURSE.
Controllers should not key the radio transmitter
continuously during radar approaches to preclude a
lengthy communications block. The decision on how often
transmitters are unkeyed is the controller's prerogative.
b. Issue trend information as required, to indicate
target position with respect to the azimuth and
elevation cursors and to describe target movement as
appropriate corrections are issued. Trend information
may be modified by the terms “RAPIDLY” or
“SLOWLY,” as appropriate.
“Going above/below glidepath.”
“Going right/left of course.”
“Above/below glidepath and coming down/up.”
“Above/below glidepath and holding.”
“Left/right of course and holding/correcting.”

FAAO JO 7110.65, Para 5-13-3, Monitor Information.
5-12-5. DISTANCE FROM TOUCHDOWN
Inform the aircraft of its distance from touchdown at
least once each mile on final approach.
(Number of miles) MILES FROM TOUCHDOWN.
5-12-6. DECISION HEIGHT
Inform the aircraft when it reaches the published
AT DECISION HEIGHT.
5-12-7. POSITION ADVISORIES
a. Continue to provide glidepath and course
information prescribed in para 5-12-4, Glidepath
and Course Information, subparas a and b, until the
aircraft passes over threshold.
Glidepath and course information provided below decision
height is advisory only. 14 CFR Section 91.175 outlines
pilot responsibilities for descent below decision height.
b. Inform the aircraft when it is passing over the
OVER APPROACH LIGHTS.
c. Inform the aircraft when it is passing over the
landing threshold and inform it of its position with
respect to the final approach course.
OVER LANDING THRESHOLD, (position with respect to

5-12-8. APPROACH GUIDANCE
a. Discontinue precision approach guidance
1. Requested by the pilot.
2. In your opinion, continuation of a safe
approach to the landing threshold is questionable.
3. The aircraft passes over landing threshold.
4. The pilot reports the runway/approach lights
in sight and requests to or advises that he/she will
A pilot's report of “runway in sight” or “visual” is not a
request to proceed visually.
b. When precision approach guidance is discontinued in accordance with subpara a, advise the
aircraft of its position and to proceed visually.
(Distance) MILE(S) FROM TOUCHDOWN, PROCEED
VISUALLY (additional instructions/clearance as
c. After a pilot has reported the runway/approach
lights in sight and requested to or advised that he/she
will proceed visually, and has been instructed to
proceed visually, all PAR approach procedures shall
d. Continue to monitor final approach and
frequency. Pilots shall remain on final controller's
frequency until touchdown or otherwise instructed.

5-12-9. COMMUNICATION TRANSFER
Issue communications transfer instructions.
CONTACT (terminal control function) (frequency, if
required) AFTER LANDING.
Communications transfer instructions should be delayed
slightly until the aircraft is on the landing roll-out to
preclude diversion of the pilot's attention during transition

5-12-10. ELEVATION FAILURE
a. If the elevation portion of PAR equipment fails
during a precision approach:
1. Discontinue PAR instructions and tell the
aircraft to take over visually or if unable, to execute
a missed approach. If the aircraft executes a missed
approach, apply subpara 2 below.
NO GLIDEPATH INFORMATION AVAILABLE. IF
RUNWAY, APPROACH/RUNWAY LIGHTS, NOT IN
SIGHT, EXECUTE MISSED APPROACH/(alternative
2. If a surveillance approach, ASR or PAR
without glide slope, is established for the same
runway, inform the aircraft that a surveillance
approach can be given. Use ASR or the azimuth
portion of the PAR to conduct the approach and apply
Chapter 5, Radar,
Section 11, Surveillance
Approaches- Terminal. When the PAR azimuth is
used, inform the pilot that mileage information will
be from touchdown, and at those runways where
specific minima have been established for PAR
without glideslope, inform the pilot that the PAR
azimuth will be used for the approach.
1. Approach information when PAR azimuth used:
“This will be a surveillance approach to runway three six.
Mileages will be from touchdown.”
“This will be a surveillance approach to runway three six
using P-A-R azimuth. Mileages will be from touchdown.”
2. Descent Instructions:
“Five miles from touchdown, descend to your minimum
descent altitude/minimum altitude.”
FAAO JO 7110.65, Para 5-10-2, Approach Information.
FAAO JO 7110.65, Para 5-11-4, Descent Instructions.
b. If the elevation portion of the PAR equipment is
inoperative before starting a precision approach,
apply subpara a2.
5-12-11. SURVEILLANCE UNUSABLE
PAR approaches may be conducted when the ASR is
unusable provided a nonradar instrument approach
will position the aircraft over a navigational aid or
DME fix within the precision radar coverage, or an
adjacent radar facility can provide a direct radar
handoff to the PAR controller.
The display of the NAVAID or DME fix in accordance with
para 5-3-2, Primary Radar Identification
Methods, is not required provided the NAVAID or DME fix
can be correlated on a PAR scope.
