Section 4. Flight Plan Handling
6-4-1. FLIGHT PLAN ACTIVATION
a. If a departure report has not been received
within a predetermined time, but not less than 1 hour
of the proposed departure time, and specific
arrangements have not been made to activate the
flight plan, cancel and store in the history file.
b. The FSS history file is used for statistical and
historical purposes. Movement messages, pilot
briefings, and aircraft contacts are stored in the
history files automatically and retained for 15 days.
c. When a pilot reports an actual departure time of
more than 2 hours prior to the current clock time,
request an updated ETE based on the aircraft's
present position. Amend the ETE in the existing
flight plan and activate the flight plan using the
current time as the time of departure and inform the
pilot of the new ETA.
6-4-2. DEPARTURE REPORT MESSAGE
When a pilot activates a flight plan with other than the
facility holding the flight
plan, transmit a numbered
message to the departure tiein facility.
N98765 D1645 RCA ALW
6-4-3. ACKNOWLEDGING NUMBERED
Acknowledge a numbered message as soon as
practical after receipt. Prefix the acknowledgement
with the letter “R” followed by a space and then the
3digit message number.
6-4-4. FLIGHT NOTIFICATION MESSAGE
a. When a departure report is received or the pilot
requests an assumed departure, transmit a flight
notification message to the destination tiein facility
as specified in FAA Order JO 7350.8, Location
Identifiers. Telephone or interphone, when available,
may be used for flights of 30 minutes or less. The
flight notification message must contain the
1. Type of flight plan (VFR or IFR).
2. Aircraft identification.
3. Aircraft type.
4. Departure point.
6. ETA (If more than 24 hours, may use DTG).
7. Remarks, preceded by a $ sign (as
VFR N2346F AC11/U PVU BOI 1348 $ASMD DEP
The operational system will automatically format the
required items and transmit the flight notification
message when activated.
b. When the proposed flight plan is received from
another FSS, base operations (BASOPS), or direct
user access terminal (DUAT) vendor and the
departure facility has only partial flight plan data, add
a remark indicating the Service B address of the
facility holding the complete flight plan. Operational
systems will automatically add this to the “Remarks”
section of the flight plan.
VFR N12345 C182/U PVU BOI 1958 $FPKIADXCLX
c. If the pilot elects to close the flight plan with a
facility other than the designated tiein facility, send
the flight notification message with remarks to both
tiein facilities; for example, FIRIV FAI. The
designated tiein facility must assume both
destination and search and rescue responsibility
FF PAENYFYX PAFAYFYX
VFR N2346F AC11 JNU FAI 1303
The operational system will auto address to the tiein
facility. Because the pilot elected to FIRIV with ENA (a
facility other than the tiein facility), the message must
also be manually addressed to ENA.
d. The facility with which the pilot elects to close
the flight plan must forward a numbered closure
message to the designated tiein facility.
e. On civil flight plans, if the pilot advises of
stopover points, show these in remarks.
VFR N12345 C182/U PVU BOI 1958 $LNDG
f. On military flight plans, in remarks use coded
data pertinent to services, passengers, or cargo. In the
absence of remarks, enter the letter “N” (meaning
none) in the remarks field.
DOD Flight Information Publication, General Planning Document.
1. Flight notification messages with remarks
generate an alert at designated workstations.
2. When landing at a civil airport, if there are no
remarks with the flight notification message, it is
placed on the Inbound List with no alerts for
3. When landing at a military airport, all flight
notification messages generate an alert.

VFR R54321 2/UH1/U SLC BOI 1943 $N
g. Address military stopover flight notification
messages to and obtain acknowledgements from the
destination tiein facility serving all destinations.
1. For the first leg, transmit the items in
subparas 644a and 644f.
2. For each subsequent leg, transmit the
destination, ETE, and remarks applicable to that leg
only, prior to (/). Remarks pertaining to the entire
flight are entered in the “Remarks” section of the
original flight plan and are transmitted to all
3. Separate stopover legs by inserting a slant (/)
at the end of each leg except the last. Begin each leg
on a new line.

4. For composite flights, specify type flight plan
as the first item of each leg.
5. When en route delays are involved, include
delay time in ETE.
h. Apply military flight plan procedures to all civil
aircraft landing at military bases.
It is the civil pilot's responsibility to obtain permission
(from military authorities) to land at a military base.
i. Apply civil flight plan procedure to civil aircraft
departing military bases and en route to civil airports.
6-4-5. SUSPENDING FLIGHT
a. Suspend the flight notification message or
proposal message until acknowledgment is received
from the addressee, then store in the history file.
b. If an acknowledgment is not received within the
following time period, use the telephone or
interphone to assure delivery.
1. Thirty minutes after departure if ETE is
between 30 minutes and 2 hours.
2. One hour before ETA if ETE is 2 hours or
3. Thirty minutes after departure if remaining
overnight (RON)/VIP information is contained in
remarks of a military flight notification.
c. When an acknowledgment for a message is
required and has not been received in accordance with
the procedure described above, retransmit the
complete message to the addressee.
d. Messages awaiting acknowledgment are suspended on the Suspense List. It contains a list of all
numbered Service B messages and those messages
transmitted from the flight plan mask not acknowledged by all the addressees.
1. The message identification is the aircraft
identification for flight notifications and/or the
message number for all other message types.
2. Acknowledgments received via NADIN will
be automatically processed if they are in the proper
3. Improperly formatted acknowledgments will
be directed to a list for manual processing and will
generate an alert at designated workstations for
4. The Suspense List will display the aircraft
identification and message numbers in chronological
order of transmission times and the addressees for
each message with an indication of those that have
5. If a transmission has not been acknowledged
by all addressees within 30 minutes, an alert will be
generated by the operational system.
6. Upon receipt of a Suspense alert, retransmit
the message to addressees who have not acknowledged the message.
7. When an acknowledgment message is
received from any other source, such as interphone/telephone or facility guarding for the addressee, the
specialist must manually acknowledge the message.
6-4-6. ACKNOWLEDGING FLIGHT
Acknowledge a flight notification message or
proposal as soon as practical after receipt. Prefix the
acknowledgment with the letter “R” followed by a
space and then the full aircraft identification.
The operational system will automatically acknowledge
flight notification messages which are received in or have
been edited into the correct format.
6-4-7. ACTION BY ADDRESSEES
In addition to acknowledging receipt of flight
notification, addressees must take the following
a. Military IFR flights.
1. Notify BASOPS, if applicable, of the
2. Upon request, deliver flight plan amendments to the ARTCC.
3. File the flight notification message in the
operational system history files or with the daily

destination tiein facility for the next destination.
b. Military VFR flights.
1. Notify BASOPS, if applicable, of the
2. Suspense the message, await
closure/cancellation/departure and assume
destination station responsibility.
3. Forward the departure time to the destination
tiein facility and assume departure station responsibility.
4. All flight notification messages are suspended on the Inbound List. An entry on the list will
remain there until the flight plan is closed. Thirty
minutes after the ETA, if the flight plan has not been
closed, it is considered overdue and will generate an
alert at designated workstations.
c. If no information is received (for example,
departure time, revised ETA) indicating that the flight
is still active prior to the void time, close the flight
plan and note this on the flight notification message
6-4-8. MAJOR FLIGHT PLAN CHANGES

6-4-9. CHANGE IN ETA
When an aircraft wants to change its ETE, obtain a
new ETA, and forward the information to the
destination tiein facility as a numbered message. The
destination tiein facility must acknowledge and,
thereafter, use the new ETA as the standard for any
necessary followup action; for example, QALQ
