Section 13. Use of PAR for Approach
5-13-1. MONITOR ON PAR EQUIPMENT
USAF not applicable. Aircraft conducting precision
or nonprecision approaches shall be monitored by
PAR equipment if the PAR final approach course
coincides with the NAVAID final approach course
from the final approach fix to the runway and one of
the following conditions exists:
1. The provisions of this section do not apply to monitoring
simultaneous ILS, MLS, or ILS and MLS approaches.
2. This procedure is used in PAR facilities operated by the
FAA and other military services at joint-use civil/military
locations and military installations during the operational
hours of the PAR.
a. The reported weather is below basic VFR
b. USA Not applicable. At night.
c. Upon request of the pilot.
FAAO JO 7110.65, Para 5-9-7, Simultaneous Independent
ILS/MLS Approaches- Dual & Triple.
5-13-2. MONITOR AVAILABILITY
a. Inform the aircraft of the frequency on which
monitoring information will be transmitted if it will
not be the same as the communication frequency used
for the approach.
RADAR MONITORING ON LOCALIZER VOICE
and if applicable,
CONTACT (terminal control function) (frequency, if
required) AFTER LANDING.
b. If the approach is not monitored, inform the
aircraft that radar monitoring is not available.
RADAR MONITORING NOT AVAILABLE.
c. If conditions prevent continued monitor after
the aircraft is on final approach, advise the pilot. State
the reason and issue alternate procedures as
(Reason), RADAR MONITORING NOT AVAILABLE,
Approach monitoring is a vital service, but during the
approach, the controller acts primarily as a safety observer
and does not actually guide the aircraft. Loss of the radar
monitoring capability (and thus availability) is no reason
to terminate an otherwise good instrument approach.
Advise the pilot that radar contact has been lost (or other
reason as appropriate), that radar monitoring is not
available, and of actions for the pilot to take in either
proceeding with or breaking off the approach; i.e., contact
tower, remain on PAR frequency, etc.
5-13-3. MONITOR INFORMATION
When approaches are monitored, take the following
a. Advise the pilot executing a nonprecision
approach that glidepath advisories are not provided.
Do this prior to the pilot beginning the final descent.
GLIDEPATH ADVISORIES WILL NOT BE PROVIDED.
b. Inform the aircraft when passing the final
approach fix (nonprecision approaches) or when
passing the outer marker or the fix used in lieu of the
outer marker (precision approaches).
c. Advise the pilot of glidepath trend information
(precision approaches) and course trend information
to indicate target position and movement with respect
to the elevation or azimuth cursor when the aircraft
target corresponds to a position of well above/below
the glidepath or well left/right of course and
whenever the aircraft exceeds the radar safety limits.
Repeat if no correction is observed.
Course trend information:
“(Ident), well right/left of P-A-R course, drifting further
Glidepath trend information:
“(Ident), well above/below P-A-R glidepath.”
FAAO JO 7110.65, Para 5-12-4, Glidepath and Course
d. If, after repeated advisories, the aircraft is
observed proceeding outside the safety limits or a
radical target deviation is observed, advise the
aircraft if unable to proceed visually, to execute a
missed approach. Issue a specific altitude and
heading if a procedure other than the published
missed approach is to be executed.
(Position with respect to course or glidepath). IF NOT
VISUAL, ADVISE YOU EXECUTE MISSED APPROACH
e. Provide monitor information until the aircraft is
over the landing threshold or commences a circling
f. Provide azimuth monitoring only at locations
where the MLS glidepath and the PAR glidepath are
