Section 2. Instrument Approach Data
9-2-1. GENERAL
ARTCCs are responsible for the tabulation and reporting of
instrument approach data for those nontower, nonapproach
control, or VFR tower airports under the ARTCC's
jurisdiction to which instrument approaches are conducted.
Instrument approach data are used primarily to determine
the need and priority order of approach aids, such as ILS/MLS
and VOR. Therefore, it is not necessary to report
instrument approaches made to purely military airports
unless the FAA is responsible for providing the aids for
that airport. One count must be recorded for each approach
meeting the criteria.
9-2-2. INSTRUMENT APPROACHES
a. An instrument approach is an approach made to an
airport by an aircraft on an IFR flight plan when the
visibility is less than 3 miles or the ceiling is at or
below the minimum initial approach altitude.
b. Where no weather reporting service is available at
nontower satellite airports, the following criteria in
descending order must be used to determine valid
instrument approaches.
1. A pilot report.
2. If the flight has not canceled its IFR flight plan
prior to reaching the initial approach fix.
3. The official weather as reported for any airport
located within 30 miles of the airport to which the
approach is made.
9-2-3. AIRPORTS REPORTED
Instrument approaches must be reported for all airports
where instrument approaches are conducted. Reporting is
the responsibility of the facility having the authority
for clearing the approach. Therefore, the ARTCC is
responsible to report instrument approaches for the
nontower airports and nonapproach control (VFR) airports
in its area. At airports where there is an FAA VFR tower,
the ARTCC and the tower must determine which facility must
maintain the count. If the tower counts the approaches, it
must forward the appropriate totals to the ARTCC for
inclusion in the center's monthly report. (VFR towers do
not report instrument approaches to Washington.) When the
ARTCC provides approach control on a part-time basis;
i.e., during periods when the primary approach control
facility is closed, the ARTCC must forward the instrument
approach count for those hours to the primary approach
control facility for inclusion in their monthly report.
9-2-4. FAA FORM 7230-16, APPROACH DATA WORKSHEET
FAA
Form 7230-16 is a worksheet furnished for the purpose of
recording instrument approaches. It does not have a
specific arrangement allowing each facility to tailor it
to its own needs. Instrument approaches will be counted by
the standard air carrier, air taxi, general aviation,
and military categories. At the end of the month,
the totals, by airport, will be transferred to FAA Form
7230-12. FAA Form 7230-16 must be retained in the
facility's files.
9-2-5. FAA FORM 7230-12, INSTRUMENT APPROACHES MONTHLY
SUMMARY
FAA
Form 7230-12 is a monthly form, submitted by both ARTCC
and terminal approach control facilities, for reporting
the number of instrument approaches made at airports for
the month. The facility's name and location will be
entered; two digits each will be used for the month and
the year (January would be 01), and the three-letter
identifier filled in at the top of the form. ARTCCs must
check box H: ARTCC or CERAP. ARTCCs must not enter any
data in the block for instrument approaches terminating at
a primary approach airport. ARTCCs list all airports,
using a three-character identifier, under the heading
“Instrument Approaches to Nonapproach Control Airport,”
with the respective monthly totals by category. If an
ARTCC has more airports than can be listed on the front,
continue on the back of the form. In this case, the
ARTCC's identifier and the month and the year must be
entered again on the back. Only ARTCCs and approach
controls submit this form. Under no circumstances should
two facilities report the same airport. Therefore, it may
be necessary for facilities to make arrangements to ensure
no duplicate reporting of instrument approaches.
9-2-6. DISTRIBUTION AND AMENDMENT
a. Distribute FAA Form 7230-12 as follows (it may be
combined in one envelope with the other monthly forms):
1. The original and one copy to the Service Area
office not later than the 2nd workday (Monday-Friday) of
the following month.
2. One copy to the facility's files (with FAA Form
7230-16).
3. One copy to the local airport officials as
requested.
b. Correct any errors in the forms sent in last month
by completing a new form, circling the revised fields, and
marking the form “AMENDED COPY.” Amended copies of forms
more than 1 month old will not be accepted unless approval
has been obtained from Safety and Operations Support by
the Service Area office. Send amended copies along with
the current reporting month's forms to the Service Area
office.
9-2-7. FORWARD COPY TO ADJACENT SERVICE AREA
If
the report contains data for an airport which is under the
administrative jurisdiction of another Service Area
office, forward a copy to that Service Area office.
