Air Traffic Controller / FAA ATSA Exam Foundational Air Traffic Control Knowledge flashcards — 53 questions with answers

  1. What are the six classes of US airspace, and which letter is not used?

    Classes A, B, C, D, E (controlled) and G (uncontrolled). Class F is not used in the United States.

  2. Class A airspace covers what altitude range, and what flight rules are required?

    From 18,000 ft MSL up to and including FL600. Operations require an IFR clearance; VFR flight is not permitted.

  3. What is the typical shape and structure of Class B airspace?

    An 'upside-down wedding cake' of concentric rings surrounding the busiest airports, generally from the surface up to 10,000 ft MSL, with shelves widening at higher altitudes.

  4. What clearance is required to enter Class B airspace?

    An explicit ATC clearance: the pilot must hear 'cleared into the Class Bravo' before entering.

  5. What are the standard dimensions of Class C airspace?

    A 5 NM inner core from surface to 4,000 ft AGL and a 10 NM outer shelf from 1,200 to 4,000 ft AGL, surrounding airports with an operational control tower and radar approach control.

  6. What communication is required to enter Class C or Class D airspace?

    Two-way radio communication must be established with ATC; if the controller states the aircraft's call sign, communication is established (an explicit clearance is not required as in Class B).

  7. What defines Class D airspace?

    Airspace around an airport with an operational control tower (no radar approach control), typically surface up to 2,500 ft AGL within about a 4 NM radius.

  8. What is the difference between Class E and Class G airspace?

    Class E is controlled airspace where ATC service is available; Class G is uncontrolled airspace where ATC has no authority or responsibility for separation.

  9. What is the primary function of an Air Traffic Control Tower (ATCT)?

    To control aircraft and vehicles operating on the runways, taxiways, and in the immediate airport vicinity (the surface movement area and traffic pattern).

  10. What does a TRACON do?

    A Terminal Radar Approach Control facility provides radar separation and sequencing for aircraft arriving, departing, and transiting the terminal area, typically within about 30-50 NM and below 10,000-17,000 ft.

  11. What is the role of an ARTCC (Center)?

    An Air Route Traffic Control Center provides en route separation and control for IFR aircraft flying between terminal areas, primarily in high-altitude and en route airspace.

  12. What does a Flight Service Station (FSS) provide?

    Pre-flight and in-flight services such as weather briefings, flight plan filing, and advisories; an FSS does not provide ATC separation services.

  13. In what order does an IFR flight typically transfer between facilities from departure to arrival?

    Clearance Delivery/Ground/Tower (ATCT), then departure (TRACON), then Center (ARTCC), then arrival/approach (TRACON), then Tower (ATCT) for landing.

  14. List the general phases of flight in order.

    Taxi-out, takeoff, departure/climb, en route (cruise), descent, approach, landing, and taxi-in.

  15. What is a handoff in ATC?

    The transfer of radar identification and control responsibility for an aircraft from one controller (or sector/facility) to another, including the transfer of communications to the next frequency.

  16. What is the standard radar separation minimum within 40 NM of the antenna in terminal airspace?

    3 NM lateral separation.

  17. What is the standard radar separation minimum beyond 40 NM of the antenna or in en route airspace?

    5 NM lateral separation.

  18. What is the standard vertical separation minimum below FL290?

    1,000 feet.

  19. What is RVSM and what separation does it allow?

    Reduced Vertical Separation Minimum allows 1,000 ft vertical separation between FL290 and FL410 for approved aircraft (instead of the older 2,000 ft).

  20. Above FL410 (outside RVSM), what is the vertical separation minimum?

    2,000 feet.

  1. What is wake turbulence separation and why is it applied?

    Additional spacing behind a heavier aircraft to protect a following lighter aircraft from wingtip-generated wake vortices; minima increase as the weight difference increases (e.g., behind Super/Heavy aircraft).

  2. What is visual separation?

    Separation applied when a controller or a pilot sees the relevant traffic and maintains visual contact to keep aircraft apart, used in terminal areas in visual conditions.

  3. What is procedural (non-radar) separation?

    Separation achieved without radar by using time, distance/fixes, and altitude assignments based on pilot position reports, applied where radar coverage is unavailable.

  4. What is sequencing in ATC?

    Establishing the order in which aircraft will arrive at or depart from a point (such as a runway or fix) to maintain a safe, efficient, orderly flow.

  5. What is spacing in ATC?

    The distance or time interval maintained between consecutive aircraft in a sequence to preserve required separation and an efficient flow.

  6. Name three techniques controllers use to adjust spacing in a sequence.

    Speed control, vectoring (heading changes/path stretching), and holding; altitude changes and approach delays can also be used.

  7. What is vectoring?

    Providing aircraft with assigned headings based on radar to guide them along a desired path for navigation, separation, sequencing, or noise abatement.

  8. In standard ATC phraseology, how is 'affirmative' and 'negative' used?

    'Affirmative' means yes; 'Negative' means no. They replace ambiguous words to avoid confusion.

  9. What does the phrase 'say again' mean in ATC phraseology?

    A request to repeat the last transmission (or a specified part of it) because it was not received or understood.

  10. What does 'roger' mean, and what does it NOT mean?

    'Roger' means 'I have received all of your last transmission.' It does NOT mean yes/no or that a clearance/instruction will be complied with.

  11. What is the difference between 'wilco' and 'roger'?

    'Wilco' means 'I understand your message and will comply.' 'Roger' only acknowledges receipt without indicating compliance.

  12. What does 'standby' mean in ATC communication?

    'Wait and I will call you'; it is not an approval or denial, and the controller will resume contact shortly.

  13. Spell the ICAO phonetic alphabet for the letters A through E.

    A-Alpha, B-Bravo, C-Charlie, D-Delta, E-Echo.

  14. Spell the ICAO phonetic alphabet for the letters K, P, Q, V, and Z.

    K-Kilo, P-Papa, Q-Quebec, V-Victor, Z-Zulu.

  15. How are the numbers 3, 5, and 9 pronounced in aviation radio phraseology?

    3 = 'tree', 5 = 'fife', 9 = 'niner' (used to reduce confusion over the radio).

  16. How is the number 1500 spoken in aviation when stating an altitude?

    'One thousand five hundred' (thousands and hundreds are spoken as whole numbers; digits like flight levels are spoken individually).

  17. What is the purpose of standardized phraseology in ATC?

    To ensure clear, concise, unambiguous communication that minimizes misunderstanding between controllers and pilots regardless of native language.

  18. What is coordination in ATC?

    The exchange of information and agreement between controllers (within or between facilities) about an aircraft's control, route, altitude, or restrictions before transferring or affecting it.

  19. What is an APREQ (approval request) in coordination?

    A request from one controller to another to approve a non-standard action (such as a route, altitude, or point-out) before it is executed.

  20. What is a 'point out' in ATC coordination?

    Notifying an adjacent controller of an aircraft that will penetrate or operate near their airspace, obtaining approval without transferring communications.

  21. What three elements are generally transferred during a radar handoff?

    Radar identification (the target/data block), control responsibility for separation, and the communications frequency.

  22. On a compass rose, what headings correspond to North, East, South, and West?

    North = 360° (or 000°), East = 090°, South = 180°, West = 270°.

  23. What is the difference between a heading and a bearing?

    A heading is the direction the aircraft's nose is pointed; a bearing is the direction (angle) to or from a point or station relative to north.

  24. What is the reciprocal of a heading, and how do you calculate it?

    The opposite direction (180° away). Add 180° if the heading is less than 180°, or subtract 180° if it is 180° or more (e.g., reciprocal of 090° is 270°).

  25. What is the difference between true north and magnetic north?

    True north is the geographic North Pole; magnetic north is where a compass points. The angular difference between them is called magnetic variation (declination).

  26. What is the difference between altitude (MSL) and flight level?

    Altitude in feet MSL is referenced to local altimeter setting and used at lower levels; a flight level (e.g., FL350 = 35,000 ft) is referenced to the standard altimeter setting 29.92 inHg at and above the transition altitude (18,000 ft in the US).

  27. Under the standard hemispheric (semicircular) rule for IFR cruising altitudes, which altitudes are used for eastbound vs westbound flights?

    Eastbound (magnetic course 000-179°) use odd thousands (e.g., FL310, FL330); westbound (180-359°) use even thousands (e.g., FL320, FL340).

  28. What is a STAR and what is a SID (DP)?

    A STAR (Standard Terminal Arrival Route) is a published arrival procedure connecting the en route structure to the destination; a SID/DP (Standard Instrument Departure) is a published departure procedure connecting the airport to the en route structure.

  29. What are the main categories of human error addressed in ATC, and what is one key mitigation?

    Slips/lapses (execution errors) and mistakes (planning/decision errors); key mitigations include standardized phraseology, readback/hearback verification, checklists, and structured coordination.

  30. What is a readback/hearback error and how is it prevented?

    A readback/hearback error occurs when a pilot reads back a clearance incorrectly and the controller fails to catch it; it is prevented by full readbacks of critical items and the controller actively listening to and correcting readbacks.

  31. Name common causes of controller fatigue and one mitigation strategy.

    Causes include long shifts, night/rotating schedules, circadian disruption, and high sustained workload; mitigations include adequate rest, strategic breaks, shift scheduling that respects circadian rhythms, and workload management.

  32. What is workload management in ATC and why does it matter?

    Prioritizing and distributing tasks to stay within mental capacity; it matters because excessive workload increases error rates and reduces situational awareness, while planning ahead keeps the controller in control of the traffic picture.

  33. What is Crew/Team Resource Management (CRM/TRM) in air traffic control?

    The effective use of all available people, information, and equipment to maintain safety, emphasizing communication, teamwork, situational awareness, workload sharing, and assertive error correction.
