number of people, an advisory may be sent. 
Additionally, there may be times when an advisory is 
not sent due to workload or the short length of time of 
the activity. 

3. 

Route information is available on the website 

and in specific advisories. Some route information, 
subject to the 56

day publishing cycle, is located on 

the “OIS” under “Products,” Route Management 
Tool (RMT), and “What’s New” Playbook. The RMT 
and Playbook contain routings for use by Air Traffic 
and NAS operators when they are coordinated 
“real

time” and are then published in an ATCSCC 

advisory. 

4. 

Route advisories are identified by the word 

“Route” in the header; the associated action is 
required (RQD), recommended (RMD), planned 
(PLN), or for your information (FYI). Operators are 
expected to file flight plans consistent with the Route 
RQD advisories. 

5. 

Electronic System Impact Reports are on the 

intranet at http://www.atcscc.faa.gov/ois/ under 
“System Impact Reports.” This page lists scheduled 
outages/events/projects that significantly impact 
the NAS; for example, runway closures, air shows, 
and construction projects. Information includes 
anticipated delays and traffic management initia-
tives (TMI) that may be implemented.

 VFR Flights 

(See Appendix 4, FAA Form 7233

4 – International 

Flight Plan) 

a. 

The requirements for the filing and activation of 

VFR flight plans can vary depending in which 
airspace the flight is operating. Pilots are responsible 
for activating flight plans with a Flight Service 
Station. Control tower personnel do not automatical-
ly activate VFR flight plans. 

1. 

Within the continental U.S., a VFR flight plan 

is not normally required. 

2. 

VFR flights (except for DOD and law 

enforcement flights) into an Air Defense Identifica-
tion Zone (ADIZ) are required to file DVFR flight 
plans. 

NOTE

 

Detailed ADIZ procedures are found inSection 6, National 

Security and Interception Procedures, of this chapter. (See 
14 CFR Part 99). 

3. 

Flights within the Washington, DC Special 

Flight Rules Area have additional requirements that 
must be met. Visit http://www.faasafety.gov for the 
required Special Awareness Training that must be 
completed before flight within this area. 

4. 

VFR flight to an international destination 

requires a filed and activated flight plan. 

NOTE

 

ICAO flight plan guidance is published in ICAO Document 
4444 PANS

ATM Appendix 2. 

b. 

It is strongly recommended that a VFR flight 

plan be filed with a Flight Service Station or 
equivalent flight plan filing service. When filing, 
pilots must use FAA Form 7233

4, International 

Flight Plan or DD Form 1801. Only DOD users,  and 
civilians who file stereo route flight plans, may use 
FAA Form 7233

1, Flight Plan. Pilots may take 

advantage of advances in technology by filing their 
flight plans using any available electronic means. 
Activating the flight plan will ensure that you receive 
VFR Search and Rescue services. 

c. 

When a stopover flight is anticipated, it is 

recommended that a separate flight plan be filed for 
each leg of the flight. 

d. 

Pilots are encouraged to activate their VFR 

flight plans with Flight Service by the most 
expeditious means possible. This may be via radio or 
other electronic means. VFR flight plan proposals are 
normally retained for two hours following the 
proposed time of departure. 

e. 

Pilots may also activate a VFR flight plan by 

using an assumed departure time. This assumed 
departure time will cause the flight plan to become 
active at the designated time. This may negate the 
need for communication with a flight service station 
or flight plan filing service upon departure. It is the 
pilot’s responsibility to revise his actual departure 
time, time en route, or ETA with flight service. 

NOTE

 

Pilots are strongly advised to remain mindful when using 
an assumed departure time. If not updated, search and 
rescue activities will be based on the assumed departure 
time. 

f. 

U.S. air traffic control towers do not routinely 

activate VFR flight plans. Foreign pilots especially 
must be mindful of the need to communicate directly
