background image

facilities and towers, and the update rate is not as fast. Therefore,
pilots may be requested to report established

on the final approach course.

Whether aircraft are vectored to the appropriate final approach course
or provide their own navigation

on published routes to it, radar service is automatically terminated
when the landing is completed or when

instructed to change to advisory frequency at uncontrolled airports,
whichever occurs first.

4.  Advance Information on Instrument Approach

a.

When landing at airports with approach control services and where two
or more IAPs are published, pilots

will be provided in advance of their arrival with the type of approach
to expect or that they may be vectored for

a visual approach. This information will be broadcast either by a
controller or on ATIS. It will not be furnished

when the visibility is three miles or better and the ceiling is at or
above the highest initial approach altitude

established for any low altitude IAP for the airport.

b.

The purpose of this information is to aid the pilot in planning arrival
actions; however, it is not an ATC

clearance or commitment and is subject to change. Pilots should bear in
mind that fluctuating weather, shifting

winds, blocked runway, etc., are conditions which may result in changes
to approach information previously

received. It is important that pilots advise ATC immediately they
are unable to execute the approach ATC advised

will be used, or if they prefer another type of approach.

c.

Aircraft destined to uncontrolled airports, which have automated
weather data with broadcast capability,

should monitor the ASOS/AWOS frequency to ascertain the current weather
for the airport. The pilot must advise

ATC when he/she has received the broadcast weather and state his/her
intentions.

NOTE

-

ASOS/AWOS should be set to provide one

-

minute broadcast weather updates at uncontrolled airports that are
without

weather broadcast capability by a human observer.

Controllers will consider the long line disseminated weather from an
automated weather system at an uncontrolled

airport as trend and planning information only and will rely on the
pilot for current weather information for the airport. If
the pilot is unable to receive the current broadcast weather, the last
long line disseminated weather will be issued to the pilot.
When receiving IFR services, the pilot/aircraft operator is responsible
for determining if weather/visibility is adequate for
approach/landing.

d.

When making an IFR approach to an airport not served by a tower or FSS,
after ATC advises "CHANGE

TO ADVISORY FREQUENCY APPROVED" you should broadcast your intentions,
including the type of

approach being executed, your position, and when over the final
approach fix inbound (nonprecision approach)

or when over the outer marker or fix used in lieu of the outer marker
inbound (precision approach). Continue

to monitor the appropriate frequency (UNICOM, etc.) for reports from
other pilots.

5.  Instrument Approach Procedure (IAP) Charts

a.

14 CFR Section 91.175(a), Instrument approaches to civil airports,
requires the use of SIAPs prescribed

for the airport in 14 CFR Part 97 unless otherwise authorized by the
Administrator (including ATC). If there are

military procedures published at a civil airport, aircraft operating
under 14 CFR Part 91 must use the civil

procedure(s). Civil procedures are defined with "FAA" in parenthesis;
e.g., (FAA), at the top, center of the

procedure chart. DoD procedures are defined using the abbreviation of
the applicable military service in

parenthesis; e.g., (USAF), (USN), (USA). 14 CFR Section 91.175(g),
Military airports, requires civil pilots

flying into or out of military airports to comply with the IAPs and
takeoff and landing minimums prescribed by

the authority having jurisdiction at those airports. Unless an
emergency exists, civil aircraft operating at military

airports normally require advance authorization, commonly referred to
as "Prior Permission Required" or

"PPR." Information on obtaining a PPR for a particular military airport
can be found in the Chart Supplement.

NOTE

-

Civil aircraft may conduct practice VFR approaches using DoD instrument
approach procedures when approved by the air

traffic controller.
