Section 4. Services
13-4-1. PREFILED FLIGHT
PLANS
When an aircraft operator
regularly makes two or more identical flights
per week and the FSS air traffic manager
believes that a prefiled flight plan program
would provide beneficial service, a LOA must
be executed between the concerned FSS and the
scheduled operator, preferably operators
certificated under 14 CFR Part 121 or 14 CFR
Part 135, or the military desiring to prefile
flight plans. The following criteria must be
used in coordinating and implementing the
prefiled flight plan program:
a. The LOA must
provide for but not be limited to:
1. Each operator
will furnish the appropriate FSS with a
specific contact for coordination including
the name, address, and telephone number of the
party to notify if an aircraft becomes
overdue, day or night.
2. Prefiled flight
plans must be furnished for each flight, and
signed by an authorized representative of the
company.
3. Immediate
notification by the operator of permanent
cancellation or change of prefiled flight
plans. This permanent data change must be
accepted any time prior to the activation of
the flight plan.
4. Separate and
complete flight plans must be required when
the operator desires to deviate from the
prefiled data.
5. The operator must
request activation with the appropriate FSS
not more than 24 hours or less than 1 hour in
advance of the estimated time of departure for
prefiled flight plans. Flight plans may be
automatically activated if this is contained
in a LOA.
6. Violations of
these procedures by the operator will be
grounds to terminate the program with the
operator.
b. Only those
prefiled flight plans for which the operator
has requested activation must be transmitted.
Prefiled flight plans which are known to be in
error, not going to depart, or any other
reason which will cause a cancellation or a
resubmission must not be transmitted to a
control facility.
13-4-2. PRACTICE
INSTRUMENT APPROACHES
At locations providing
Local Airport Advisories (LAA) where either an
ARTCC or an approach control facility provides
standard separation to VFR aircraft practicing
instrument approaches, provisions for handling
such aircraft must be included in a letter of
agreement.
13-4-3. OPERATION OF
AIRPORT LIGHTS
a. When a FSS is
located at an airport or at a part-time tower
location, the FSS air traffic manager may,
under the terms of a LOA with the airport
manager and the tower, assume this
responsibility provided that:
1. The controls are
extended into the station and are located
conveniently at the operating position.
2. The operating
quarters afford a sufficient view to determine
the operating status of the lights without the
specialist having to leave his/her post of
duty or an indicator is provided in the
station quarters which will show the actual
operating status.
b. FSS operating
less than 24 hours a day which have lighting
control responsibility must be guided by the
instructions in Part 3, Chapter 10, Section 6,
Airport Lighting.
13-4-4. RUNWAY EDGE
LIGHTS ASSOCIATED WITH MEDIUM APPROACH LIGHT
SYSTEM/RUNWAY ALIGNMENT INDICATOR LIGHTS
FSSs having responsibility
for the control of MALS/RAIL brightness must
comply with the instructions in para 10-6-8,
Runway Edge Lights Associated with Medium
Approach Light System/Runway Alignment
Indicator Lights.
13-4-5. LOCAL AIRPORT
ADVISORY (LAA)/REMOTE AIRPORT ADVISORY (RAA)/REMOTE
AIRPORT INFORMATION SERVICE (RAIS)
a. Provide LAA at
FSSs during the published service hours when:
1. Located on the
airport.
2. There is no
operating control tower on the airport.
3. The facility has
a continuous display of the automated weather
data or manual weather observations.
4. A discrete
frequency or the tower frequency, when the
tower is closed, is available.
5. The pilot says,
“I have the automated weather.”
b. Provide RAA at
FSSs during the published service hours when:
1. The airport
authority or airport manager has requested the
service and the facility has the resources
available to provide the service.
2. The annual
traffic density and employee productivity
factor is high enough to justify the cost of
providing the service. Published service times
may be adjusted by the facility manager to
accommodate anticipated or forecast traffic
density changes.
EXAMPLE-
Winter service hours may be longer than summer
service hours at airports that service several
popular ski resorts. Therefore, the manager
may choose to reduce or suspend summer service
to mitigate short-term productivity concerns.
3. There is no
operating control tower on the RAA airport.
4. The facility has
a continuous display of the automated weather
data or manual observations are reported to
the facility.
5. There is a remote
discrete frequency or the tower frequency is
remoted to the FSS, when the tower is closed.
6. The airport has a
traffic density of 25,000 or more aircraft
operations per year.
NOTE-
If a new airport fails to deliver 25,000
aircraft operations during the first year of
service, RAA must be discontinued. After the
first year is completed and yields 25,000 or
more aircraft operations, the decision to
continue services is evaluated on the
anniversary date and based on a minimum of
25,000 aircraft operations at the target
airport during any consecutive twelve months
of the previous 3 years.
7. The facility's
productivity factor is determined by dividing
the annual RAA service count by 16,000.
NOTE-
The productivity factor is compared to the
number of employees used to provide the
service and must be equal to or greater than
the number of employees needed to provide the
service. Normally about 2.5 employees are
factored annually to provide 10 hours of
service per day. (The .5 factor ensures
employee vacations, training periods, sick
days, and daily break periods).
c. Provide RAIS to
support special events at airports during
NOTAM D service hours when:
1. The airport
authority has requested the service at least
30 days in advance and the facility has the
resources available to provide the service.
2. There is no
operating control tower at the airport.
3. The facility has
discrete communications capability at the
airport.
4. The RAIS airport
has automated weather reporting for the pilots
with voice capability.
5. The pilot says,
“I have the automated weather.”
6. A NOTAM D has
been issued at least 24 hours in advance.
13-4-6. AUTOMATIC FLIGHT
INFORMATION SERVICE (AFIS) - ALASKA FSSs ONLY
a. Alaska FSS AFIS
provides a continuous broadcast of recorded
non-control information at airports in Alaska
where a Flight Service Station (FSS) provides
local airport advisory service. The AFIS
broadcast automates the repetitive
transmission of essential but routine
information such as weather, wind, altimeter,
favored runway, breaking action, airport
NOTAMs and other applicable information. The
information is continuously broadcast over a
discrete VHF radio frequency (usually the ASOS
frequency). Pilots are urged to listen to AFIS
when arriving, departing, and operating within
the airport advisory area as it relieves
frequency congestion on the local airport
advisory frequency. AFIS is not used in
terminal areas and does not contain approach
information.
b. Before
transmitting, the voice message must be
reviewed to ensure content is complete and
accurate. Ensure specialist speech rate does
not exceed 100 words per minute, the
enunciation is of the highest quality, and
each part of the message is easily understood.
c. Keep messages as
brief and as concise as practical.
d. ASOS must not be
allowed to broadcast weather concurrent with
AFIS.
e. During hours of
non-operation of Alaska FSS AFIS, ASOS
broadcast capability must allow the automated
weather report to be broadcast on the ASOS
frequency in the one minute update mode and
include the following information:
1. The FSS hours of
operation or in the case of a seasonal FSS, a
statement that the FSS is closed for the
season.
2. The appropriate
common traffic advisory frequency (CTAF).
3. The frequency for
operating pilot controlled lighting.
4. The FSS and
frequency for additional information.
f. The FSS air
traffic manager that has responsibility for a
FSS utilizing AFIS equipment must ensure that
ATCS personnel assigned to duty in that FSS
are in compliance with the AFIS requirements
and that they receive training to utilize AFIS
equipment and are familiar with required
procedures.
13-4-7. TRANSMISSION OF
MESSAGES FROM AIRPORT INSPECTORS
Accept administrative
messages from airport inspectors for
transmission to NFDC and other FAA offices as
prescribed in Chapter 2 of FAAO 5010.4,
Airport Safety Data Program. |
