Airspace classification — Part 107 practice questions

27 practice questions on airspace classification from the FAA remote pilot knowledge test, each with the correct answer and why it is correct.

1. 01

   What is the primary purpose of designating special use airspace?

   • To provide additional landing areas for aircraft
   • To confine certain activities and impose limitations on aircraft operationsCorrect
   • To designate areas for recreational flying only
   • To indicate areas with the best weather conditions for flying
   Why

   To confine certain activities and to limit what other aircraft may do there. The designation is a container — it exists because something inside needs to be kept in, or everyone else needs to be kept out — which is why the various types differ mainly in how hard that limitation bites.

2. 02

   What is the primary purpose of warning areas?

   • To prohibit all aircraft operations
   • To warn pilots of potential dangerCorrect
   • To designate areas for military training only
   • To indicate areas of severe weather
   Why

   To warn of activity hazardous to aircraft in airspace the United States does not solely control — typically beginning offshore. The government's lack of sole jurisdiction is what stops it being a restricted area: the hazard is comparable, the authority to prohibit is not.

3. 03

   What is the primary purpose of Military Operation Areas (MOAs)?

   • To restrict all civilian aircraft operations
   • To separate certain military training activities from IFR trafficCorrect
   • To designate areas for commercial airline use only
   • To indicate areas of high-altitude weather phenomena
   Why

   To separate certain military training from IFR traffic. An MOA does not close the airspace: VFR aircraft may enter, and are simply expected to exercise caution when it is active. It is a segregation device rather than a prohibition.

4. 04

   What distinguishes Controlled Firing Areas (CFAs) from other special use airspace?

   • CFAs are always active and never suspend operations
   • CFAs are only used for military operations
   • CFAs must suspend activities when an aircraft approaches the areaCorrect
   • CFAs are always charted on aeronautical maps
   Why

   A CFA suspends its activity when an approaching aircraft is detected, which is why it alone is not charted — there is nothing for a pilot to avoid, because the activity stops rather than the aircraft diverting. Every other special use area appears on the chart precisely because avoidance is the pilot's job.

5. 05

   What services are included in Local Airport Advisory (LAA)?

   • Air traffic control and ground control
   • Runway maintenance and repair
   • Local airport advisories and automated weather reportingCorrect
   • Fuel services and aircraft maintenance
   Why

   LAA is an advisory service from a Flight Service facility: local airport advisories together with automated weather reporting. Advisory is the operative word — no clearances, no separation, and nothing to do with ground services like fuel or maintenance.

6. 06

   What type of notice is issued to designate a Temporary Flight Restriction (TFR)?

   • A local weather report
   • A flight data center (FDC) Notice to Airmen (NOTAM)Correct
   • A terminal area forecast (TAF)
   • A pilot weather report (PIREP)
   Why

   An FDC NOTAM — flight data centre. TFRs appear around wildfires, disaster sites, sporting events and VIP movements, which means they can be issued after you planned the flight and before you arrive. None of the weather products carry them.

7. 07

   How are Military Training Routes (MTRs) with segments above 1,500 feet AGL identified?

   • By four number characters
   • By three number charactersCorrect
   • By two letter characters
   • By a combination of letters and numbers
   Why

   Three digits. The digit count encodes the altitude band: routes with any segment above 1,500 feet AGL get three characters, those flown entirely at or below it get four. Military aircraft transit these at high speed and low level, which is why knowing one crosses your site matters.

8. 08

   What is a recommended way for pilots to check for Temporary Flight Restrictions (TFRs)?

   • Call the nearest airport tower
   • Check the weather forecast
   • Visit the FAA website at www.tfr.faa.govCorrect
   • Look for signs posted at the launch site
   Why

   tfr.faa.gov publishes them, and it is worth checking on the day rather than in advance — a TFR issued for a VIP visit or a fire can appear with very little notice. Nothing at the launch site will tell you one exists.

9. 09

   How many categories of airspace are there?

   • One
   • TwoCorrect
   • Three
   • Four
   Why

   Two at the top level — controlled and uncontrolled — which then subdivide. Keeping the two-tier structure straight is what makes the classes navigable: the question of whether you need ATC authorization is decided at the controlled/uncontrolled level before any letter is involved.

10. 10

    Which class of airspace typically extends from the surface to 10,000 feet MSL surrounding the nation's busiest airports?

    • Class A
    • Class BCorrect
    • Class C
    • Class D
    Why

    Class B, drawn around the busiest airports and often described as an inverted wedding cake — it reaches the surface at the centre and steps outward in shelves as it rises. Class A is high-altitude en-route airspace and has no surface component at all.

11. 11

    How are prohibited areas indicated on aeronautical charts?

    • With an 'R' followed by a number
    • With a 'P' followed by a numberCorrect
    • With an 'A' followed by a number
    • With a 'W' followed by a number
    Why

    A P followed by a number. The letter matches the designation across the whole family — P for prohibited, R for restricted, W for warning, A for alert — so the first character tells you the category before you look anything up.

12. 12

    What potential hazards might be present in restricted areas?

    • Heavy commercial air traffic
    • Extreme weather conditions
    • Artillery firing or aerial gunneryCorrect
    • High-altitude bird migration
    Why

    Artillery firing, aerial gunnery and similar activities hazardous to aircraft that are not part of them. The hazard is the reason for the designation; heavy traffic and weather are handled by other mechanisms entirely.

13. 13

    How are restricted areas indicated on aeronautical charts?

    • With a 'P' followed by a number
    • With an 'R' followed by a numberCorrect
    • With a 'W' followed by a number
    • With an 'A' followed by a number
    Why

    An R followed by a number. Restricted does not mean prohibited — entry is possible when the area is not active or with permission from the controlling agency — which is exactly why it has its own letter rather than sharing P.

14. 14

    What is the purpose of alert areas?

    • To prohibit all flight operations
    • To inform pilots of areas with potential high-volume training or unusual aerial activityCorrect
    • To designate areas for emergency landings only
    • To indicate areas of severe turbulence
    Why

    To advise that an area sees a high volume of training or unusual aerial activity. Nothing is prohibited and nothing is restricted — pilots of both participating and nonparticipating aircraft remain equally responsible for collision avoidance inside one.

15. 15

    Which of the following is NOT listed as an 'Other Airspace Area' in the study guide?

    • Local airport advisory (LAA)
    • Temporary flight restriction (TFR)
    • Military operation area (MOA)Correct
    • National security area (NSA)
    Why

    An MOA is special use airspace, not an "other airspace area" — the two are separate top-level categories. Local airport advisories, TFRs and national security areas all sit under "other", which is the catch-all for designations that are neither a lettered class nor special use.

16. 16

    What are the four types of airspace?

    • Controlled, uncontrolled, special use, and other airspaceCorrect
    • High, medium, low, and ground level
    • Restricted, prohibited, warning, and alert areas
    • Commercial, private, military, and recreational
    Why

    Controlled, uncontrolled, special use, and other airspace. The four are not a hierarchy by altitude or by user — they are different kinds of designation, and they overlap: special use airspace such as a restricted area can sit inside controlled airspace and carries its own rules on top.

17. 17

    In which class of airspace does a remote pilot need ATC authorization before operating?

    • Class G
    • Class E above 400 feet AGL
    • Class DCorrect
    • All of the above
    Why

    Class D is controlled airspace around a towered airport, so authorization is required — as it is for Class B, Class C, and the surface area of Class E designated for an airport. Class G is the uncontrolled class where none is needed.

18. 18

    What is another name for Class G airspace?

    • Controlled airspace
    • Special use airspace
    • Uncontrolled airspaceCorrect
    • Restricted airspace
    Why

    Uncontrolled airspace. "Uncontrolled" describes the absence of ATC separation service, not an absence of rules: part 107's altitude, visibility, cloud clearance and visual line of sight requirements all apply in Class G exactly as they do elsewhere.

19. 19

    What is the primary purpose of Notices to Airmen (NOTAMs)?

    • To provide long-term weather forecasts
    • To disseminate time-critical aeronautical informationCorrect
    • To list all available airports in a region
    • To provide maintenance schedules for aircraft
    Why

    To carry time-critical information that is either temporary or arrived too late for publication — closed runways, unlit obstacles, new TFRs. It is the channel for what has changed since the chart was printed, which is why checking charts alone is insufficient.

20. 20

    Where can information about parachute jump aircraft operations be found?

    • Only in NOTAMs
    • In the Pilot's Operating Handbook
    • In the Chart Supplement U.S. and on sectional charts for frequently used sitesCorrect
    • Only through direct communication with the nearest air traffic control tower
    Why

    The Chart Supplement U.S. lists them, and frequently used sites are also printed on sectional charts. Worth knowing where they are: jumpers descend under canopy through altitudes a small unmanned aircraft may be occupying, and they cannot manoeuvre to avoid you.

21. 21

    What is the primary purpose of Published VFR Routes?

    • To provide shortcuts for commercial air traffic
    • To designate areas for UAS operations only
    • For transitioning around, under, or through complex airspaceCorrect
    • To indicate areas of severe weather
    Why

    They give VFR traffic a defined way around, under or through complex airspace without needing a clearance into it. For a remote pilot the practical consequence is that manned traffic concentrates along them, so one crossing your site raises the traffic density above what the airspace class alone suggests.

22. 22

    How are pilots notified of flight prohibitions in National Security Areas (NSAs)?

    • Through permanent markings on sectional charts
    • Via Notice to Airmen (NOTAM)Correct
    • By direct communication from air traffic control
    • Through visual warning signals on the ground
    Why

    By NOTAM. An NSA normally only requests that pilots avoid it; when the request becomes a prohibition, that change is issued as a NOTAM rather than reprinted on the chart. The chart alone will not tell you whether one is currently binding.

23. 23

    What contributes to the high degree of safety and efficiency in the U.S. air traffic system?

    • Lack of regulations for pilots
    • Minimal training requirements for air traffic controllers
    • Strict regulatory oversight by the FAACorrect
    • Absence of pilot certification processes
    Why

    Regulatory oversight — certification standards for pilots, maintenance requirements for aircraft, and training standards for controllers. The system's safety record is a product of those requirements rather than something that persists in spite of them.

24. 24

    What does ADM (Aeronautical Decision-Making) involve?

    • Automatic aircraft control systems
    • A systematic approach to risk assessment and stress managementCorrect
    • Advanced display monitors for aircraft
    • Accelerated descent methods
    Why

    A systematic approach to assessing risk and managing stress, applied before and during a flight. The name is often misread as something automated — it is the opposite: a deliberate human process, used precisely where automation offers no help.

25. 25

    Which of the following is NOT listed as a section of VFR Aeronautical Chart Symbols that remote pilots need to be familiar with?

    • Airports
    • Airspace Information
    • Weather PatternsCorrect
    • Hydrography
    Why

    There is no "Weather Patterns" section in the chart symbol guide — charts depict fixed features, not conditions. Airports, airspace information and hydrography are all genuine sections, hydrography being the water features that serve as visual landmarks.

26. 26

    What is the primary purpose of Terminal Radar Service Areas (TRSAs)?

    • To restrict all VFR traffic
    • To provide separation between IFR operations and participating VFR aircraftCorrect
    • To designate areas for UAS operations only
    • To indicate areas of severe weather
    Why

    To separate IFR traffic from VFR aircraft that choose to take part. Participation is voluntary, which is what distinguishes a TRSA from Class B or C — it is a service offered rather than an airspace requirement imposed.

27. 27

    What is the primary purpose of the Air Traffic Control (ATC) system?

    • To provide weather information to pilots
    • To prevent collisions between aircraft and organize traffic flowCorrect
    • To regulate the speed of aircraft in flight
    • To manage airport ground operations
    Why

    Preventing collisions between aircraft and organising the flow of traffic. Everything else controllers provide — weather information, traffic advisories — is secondary to those two, and it is why a part 107 airspace authorization is about fitting into that flow rather than about permission in the abstract.
