1. Primary Purpose

To prevent a collision between aircraft operating in the system and to provide a safe, orderly, and expeditious flow of traffic and to provide support for national security and homeland defense

2. Duty Priority

First priority is given to separating aircraft and issuing safety alerts.

Good judgement shall be used in prioritizing all other duties based on the requirements of the situation at hand or when encountering situations for which there is no written procedure.

Second priority is to provide support to national security and homeland defense.

3. Additional Services

Under Duty Priority. Provided to the extent possible contingent only upon higher priority duties and other factors including limitations of radar, volume of traffic, frequency congestion, and workload

Not optional for the controller

4. Procedural Preference

Automation procedures are used in preference to non-automation procedures when workload, communications, and equipment capabilities permit.

Radar separation is used in preference to non-radar separation when it will be an operational advantage and workload of communications and equipment permit.

Nonradar separation is used in preference to radar separation when an operational advantage will be gained.

5. Operational Priority

First come first served basis except for the following:



Search and rescue


Flight check

Special military and civilian ops


(Don't Let Silly Pilots Fly Stupid Drunk)

6. Air Traffic Organization

Under the chief operating officer, the ATO is responsible for ensuring the safety, efficiency, and security of air traffic operations across the entire NAS

7. Mission of the Traffic Management (TM) System

To balance air traffic demand with system capacity to ensure the maximum efficient utilization of the NAS

8. Traffic Management Units (TMUs)

Monitor and balance traffic flows within their area of responsibility in accordance with traffic management directives.

Located in all ARTCCs and at busier terminal facilities

9. Traffic Management Initiatives (TMIs)


Miles-in-Trail or Minutes-in-Trail

Fix Balancing or Airborne Holding

Sequencing Programs


Ground Delay Programs

Ground Stops

10. TMI Altitude

Tunneling - descended prior to the normal descent point at the arrival airport to remain clear of an airspace situation

Capping - cleared to an altitude lower than their requested altitude until they are clear of a particular airspace

11. TMI Miles-in-Trail (MIT)

The number of miles required between aircraft that meet specific criteria such as similar operating speeds

12. TMI Minutes-in-Trail (MINIT)

The number of minutes required between successive aircraft. Normally used in non-radar

13. TMI Fix Balancing

Assigning aircraft a fix other than in the files flight plan in the arrival or departure phase of the flight to distribute the demand

14. TMI Airborne Holding

Planned holding normally done when the operating environment supports holding and the weather conditions are expected to improve shortly

15. TMI Departure Sequencing

Assigns a departure time to achieve a constant flow of traffic over a common point

16. TMI En Route Sequencing

Assigns a departure time that will facilitate integration in the en route stream

17. ATO Air Traffic Services

AJT provide safe, secure, and efficient management for the NAS and international airspace assigned to US control

18. TMI Arrival Sequencing

Assigns fix crossing times to aircraft destined to the same airport

19. TMI Reroutes

Routings other than the filed flight plan

20. TMI Ground Delay Programs (GDP)

Aircraft are held on the ground by assigning arrival slots. Assigned an Expect Departure Clearance Time (ESCT) based on the estimated time en route and the arrival slot

21. TMI Ground Stops (GS)

Override all other TMI. Most restrictive method of TM. Aircraft must not be released without the approval of the originator of the GS.

22. VOR Airways

Also called "Victor" airways, and RNAV "Tango" routes.

For navigation below 18,000'MSL

23. Route used for navigation between FL180 and FL450

Jet routes and RNAV "Q" routes

24. Primary NAVAIDs for the nations airways


25. ATO Service Areas

Eastern, Western, Central

26. Four Positions in FSS

Flight Data/NOTAM Coordinator




27. FSS Flight Data/NOTAM Coordinator

Compile, evaluate, record, and disseminate NOTAMs and flight movement data.

Initiate required search and rescue operations

28. FSS Broadcast

Compile, evaluate, record, and disseminate weather and flight information




29. FSS Preflight

Brief and translate to pilots the current weather, NOTAMs, flow control restrictions that the pilot might encounter along the route of flight

Apply VFR Not Recommended (VNR) procedures as prescribed

30. FSS Inflight

Provides services to airborne pilots

Issue airport advisories

Relay ATC clearances

Activate and close flight plans


31. Six positions in the ATCT

Flight Data

Clearance Delivery

Local Control

Ground Control

Tower Coordinator

Tower Associate

A particular tower may or may not use all positions

32. Four positions in TRACON

Flight Data

Radar Associate

Radar Controller

Radar Coordinator

A particular sector may or may not use all positions
