departure time will be delayed 1 hour or more beyond
their filed departure time, are requested to notify ATC
of their departure time.
b. Due to traffic saturation, control personnel
frequently will be unable to accept these revisions via
radio. It is recommended that you forward these
revisions to the nearest FSS.

5-1-13. Closing VFR/DVFR Flight Plans
A pilot is responsible for ensuring that his/her VFR or
DVFR flight plan is canceled. You should close your
flight plan with the nearest FSS, or if one is not
available, you may request any ATC facility to relay
your cancellation to the FSS. Control towers do not
automatically close VFR or DVFR flight plans since
they do not know if a particular VFR aircraft is on a
flight plan. If you fail to report or cancel your flight
plan within 1/2 hour after your ETA, search and rescue
procedures are started.

5-1-14. Canceling IFR Flight Plan
a. 14 CFR Sections 91.153 and 91.169 include the
statement “When a flight plan has been activated, the
pilot‐in‐command, upon canceling or completing the
flight under the flight plan, shall notify an FAA Flight
Service Station or ATC facility.”
b. An IFR flight plan may be canceled at any time
the flight is operating in VFR conditions outside
Class A airspace by pilots stating “CANCEL MY IFR
FLIGHT PLAN” to the controller or air/ground
station with which they are communicating.
Immediately after canceling an IFR flight plan, a pilot
should take the necessary action to change to the
appropriate air/ground frequency, VFR radar beacon
code and VFR altitude or flight level.
c. ATC separation and information services will
bediscontinued, including radar services (where
applicable). Consequently, if the canceling flight
desires VFR radar advisory service, the pilot must
specifically request it.
NOTEPilots
must be aware that other procedures may be
applicable to a flight that cancels an IFR flight plan within
an area where a special program, such as a designated
TRSA, Class C airspace, or Class B airspace, has been
established.
d. If a DVFR flight plan requirement exists, the
pilot is responsible for filing this flight plan to replace
the canceled IFR flight plan. If a subsequent IFR
operation becomes necessary, a new IFR flight plan
must be filed and an ATC clearance obtained before
operating in IFR conditions.
e. If operating on an IFR flight plan to an airport
with a functioning control tower, the flight plan is
automatically closed upon landing.
f. If operating on an IFR flight plan to an airport
where there is no functioning control tower, the pilot
must initiate cancellation of the IFR flight plan. This
can be done after landing if there is a functioning FSS
or other means of direct communications with ATC.
In the event there is no FSS and/or air/ground
communications with ATC is not possible below a
certain altitude, the pilot should, weather conditions
permitting, cancel the IFR flight plan while still
airborne and able to communicate with ATC by radio.
This will not only save the time and expense of
canceling the flight plan by telephone but will quickly
release the airspace for use by other aircraft.
5-1-15. RNAV and RNP Operations
a. During the pre-flight planning phase the
availability of the navigation infrastructure required
for the intended operation, including any non-RNAV
contingencies, must be confirmed for the period of
intended operation. Availability of the onboard
navigation equipment necessary for the route to be
flown must be confirmed.
b. If a pilot determines a specified RNP level
cannot be achieved, revise the route or delay the
operation until appropriate RNP level can be ensured.
c. The onboard navigation database must be
appropriate for the region of intended operation and
must include the navigation aids, waypoints, and
coded terminal airspace procedures for the departure,
arrival and alternate airfields.
d. During system initialization, pilots of aircraft
equipped with a Flight Management System or other
RNAV-certified system, must confirm that the
navigation database is current, and verify that the
aircraft position has been entered correctly. Flight
crews should crosscheck the cleared flight plan
against charts or other applicable resources, as well as
the navigation system textual display and the aircraft
map display. This process includes confirmation of
