Airspace classification is one of the most important — and most visual — topics on the FAA Part 107 knowledge test. It accounts for approximately 15–20 percent of exam questions and requires you to read and interpret FAA sectional aeronautical charts. Mastering airspace is essential because flying a drone in the wrong class of airspace without authorization is a federal violation.

The National Airspace System (NAS) divides the sky into classes labeled A through G. For Part 107 remote pilots, the most relevant are Classes B, C, D, E, and G. Class B surrounds the busiest airports (think major hubs like LAX or JFK) and is depicted with solid blue lines in a tiered, wedding-cake shape. Class C appears around busy but smaller airports with solid magenta circles. Class D uses dashed blue lines around towered airports. Class E can start at the surface (dashed magenta boundary) or at 700 or 1,200 feet AGL, depending on the location.

Class G is uncontrolled airspace — the only class where Part 107 operations do not require prior FAA authorization. For all controlled airspace (B, C, D, and surface E), you must obtain permission through LAANC (Low Altitude Authorization and Notification Capability) or the FAA DroneZone portal before you fly.

Beyond airspace classes, the exam tests your knowledge of special use airspace such as Prohibited Areas, Restricted Areas, Military Operations Areas (MOAs), and Temporary Flight Restrictions (TFRs). You should also know how to check NOTAMs (Notices to Air Missions) for real-time airspace changes, understand stadium TFRs, and know the 400-foot AGL altitude limit with its structure exception. Practice these 10 questions to test your sectional chart reading and airspace identification skills.

Practice Questions

Question 1 of 10 0%

1. A remote pilot wants to fly in an area depicted on a sectional chart with solid blue lines forming a circle around an airport. What class of airspace surrounds this airport?

Show explanation
A dashed blue line (segmented circle) on a sectional chart indicates Class D airspace, which typically surrounds airports with an operating control tower that is not associated with Class B or C airspace.

2. What is the maximum altitude at which a remote pilot may operate a small UAS under Part 107 in uncontrolled airspace?

Show explanation
Under 14 CFR 107.51, the maximum allowable altitude is 400 feet above ground level (AGL), unless the sUAS is flown within 400 feet of a structure and does not fly higher than 400 feet above the structure's uppermost limit.

3. A remote pilot needs to operate a small UAS near a Class C airport. What must the pilot do before the flight?

Show explanation
Part 107 requires prior authorization from the FAA to operate in controlled airspace (Classes B, C, D, and some E). Pilots can use LAANC for near-real-time authorization or apply through the FAA DroneZone portal.

4. On a sectional chart, a remote pilot notices a shaded magenta area extending from the surface upward around a small airport. This most likely indicates:

Show explanation
A dashed magenta line on a sectional chart indicates Class E airspace that extends to the surface. This is common around non-towered airports with published instrument approaches.

5. What is the purpose of a Temporary Flight Restriction (TFR)?

Show explanation
TFRs are issued to restrict aircraft operations in specific areas due to hazards such as wildfire suppression, VIP movement, space launches, or large public events. Remote pilots must check NOTAMs for active TFRs before every flight.

6. Which type of airspace generally requires no ATC authorization for Part 107 operations?

Show explanation
Class G is uncontrolled airspace. Part 107 operations in Class G do not require prior ATC authorization, though all other Part 107 rules still apply.

7. A remote pilot is reviewing a sectional chart and sees a bold blue line forming a shape that resembles shelves stepping outward from an airport. This most likely depicts:

Show explanation
Class B airspace is depicted on sectional charts by solid blue lines, often in a tiered or upside-down wedding cake shape extending outward from large airports such as those serving major metropolitan areas.

8. What does LAANC stand for, and what is its primary purpose?

Show explanation
LAANC (Low Altitude Authorization and Notification Capability) automates the process of requesting and receiving airspace authorization for Part 107 UAS operations in controlled airspace near airports.

9. A remote pilot plans to operate near a stadium during a major sporting event with more than 30,000 attendees. Under Part 107, what restriction applies?

Show explanation
Under 14 CFR 91.145 and related TFRs, UAS operations are prohibited within 3 nautical miles and up to 3,000 feet AGL of stadiums and major sporting events with 30,000 or more attendees, from one hour before until one hour after the event.

10. What information can a remote pilot obtain from a Notice to Air Missions (NOTAM) before a flight?

Show explanation
NOTAMs provide time-critical aeronautical information such as temporary flight restrictions, airspace closures, runway conditions, and other safety-related notices. Remote pilots should check NOTAMs before every flight.

Frequently Asked Questions

What airspace classes are tested on the Part 107 exam?
The Part 107 exam tests knowledge of all airspace classes: Class A (generally above 18,000 feet MSL, not relevant to UAS), Class B (major airports), Class C (busy airports), Class D (towered airports), Class E (controlled airspace with various floor altitudes), and Class G (uncontrolled airspace). Remote pilots must know how to identify each class on a sectional chart.
Do I need authorization to fly a drone in controlled airspace?
Yes. Part 107 operations in Class B, C, D, and some Class E airspace require prior authorization from the FAA. The fastest way to get it is through the LAANC (Low Altitude Authorization and Notification Capability) system, which provides near-real-time approvals.
How do I read airspace boundaries on a sectional chart?
Class B airspace is shown with solid blue lines in a tiered shape. Class C uses solid magenta circles. Class D uses dashed blue lines. Class E surface areas use dashed magenta lines. Understanding these symbols is essential for Part 107 airspace questions.
