The Federal Aviation Administration’s Half 107 check is an important step for anybody aiming to turn into a licensed drone pilot for business operations within the U.S. Some questions are fairly simple, the place a dose of widespread sense might remedy them. However different questions are usually not simply tough until you’ve critically studied — however they’re virtually deliberately difficult. So of these, what are probably the most missed — or let’s consider hardest Half 107 check questions?
I reached out to my associates at Drone Pilot Floor College, which has been providing on-line Half 107 check prep programs ever since 2016. Their program affords 5, full-length follow exams that mirror the actual examination format. These exams come from a financial institution of greater than 400 pattern questions from the FAA.
If you full the follow check, Drone Pilot Floor College sends over a efficiency report and breakdown of your incorrect responses. On condition that, they’ve a powerful knowledge set of the Half 107 check questions which can be missed probably the most.
They shared these questions with me. And together with that, Drone Pilot Floor College Buyer Success Supervisor Michael McGuirt added is personal perception on why they’re so difficult — and why the right response is the way in which it’s.

Listed here are three of probably the most generally missed Half 107 check questions, and an explainer of the appropriate reply:
Inside the toughest Half 107 check questions
1) Which two elements can be utilized to compute the cloud base?
A) The temperature and the dew level
B) The temperature and the barometric strain
C) The barometric strain and the dew level
Right reply: A. The temperature and the dew level
Why college students miss this query: “College students they don’t actually perceive that ‘dew level’ is an precise temperature as a substitute of only a climate time period and that it’s used to find out the cloudbase,” McGuirt mentioned.
However understanding the connection between temperature and dew level is essential to figuring out when and the place clouds will kind.
Clarification: “The distinction between the floor temperature and the dew level temperature determines the altitude at which the air cools to its saturation level,” McGuirt mentioned. “This altitude is the place clouds start to kind.”
- A small distinction (3-5º) between temperature and dew level leads to a low cloud base, because the air doesn’t must rise far to condense.
- A massive distinction results in a greater cloud base, because the air should rise farther earlier than cooling to the dew level.
The peak of the cloud base could be discovered on varied climate apps reminiscent of UAV Forecast (1,900 ft AGL) or it may be calculated utilizing the method beneath.

Cloud Base System:
(Present Temperature – Dew Level) = Unfold
Divide the Unfold by 4.4 (if °F) or 2.5 (if °C), then multiply by 1,000 to get the cloud base in ft AGL.
Instance: If the temperature is 82ºF and the dew level is 70ºF:
82 – 70 = 12
12 / 4.4 = 2.73
2.73 x 1,000 = 2,727 ft AGL
2) What’s the solely kind of Class E airspace that requires an airspace authorization?
A) Class E Floor Space
B) Class E Extension
C) Class E Transition airspace that begins at 700 ft AGL
Right reply: A. Class E Floor Space.
Why college students miss this query: “There are eight varieties of Class E airspace and college students suppose that any class of airspace outdoors of Class G requires an airspace authorization,” McGuirt mentioned. “However the one kind of Class E that requires an airspace authorization is Floor Space Class E.”
Clarification: Class E Transition airspace that begins at 700 ft AGL or 1,200 ft AGL, or Class E Extensions don’t require an airspace authorization.
3) Which of the next is not one of many minimal message parts that should be broadcast by a typical Distant ID unmanned plane based on § 89.305?
A) The geometric altitude of the management station.
B) The battery degree of the unmanned plane.
C) The latitude and longitude of the unmanned plane.
Right reply: B. The battery degree of the unmanned plane.
Why college students miss this query: “This query is usually missed as a result of college students haven’t dedicated to reminiscence all the parts of the Distant ID Broadcast message,” McGuirt mentioned.
Clarification: There are eight parts that you need to decide to reminiscence.
- A serial quantity or session ID
- Latitude and longitude of the management station
- Geometric altitude of the management station
- Latitude and longitude of the plane
- Geometric altitude of the plane
- The speed of the plane
- A timestamp in Coordinated Common Time (UTC)
- The emergency standing of the plane
Discover that battery degree is NOT a required aspect—a standard false impression amongst test-takers.
Be ready — as a result of check scores aren’t nice
When you thought these questions had been tough, you’re not alone. For what it’s price, these three are the toughest Half 107 check questions. Nonetheless, many test-takers are lacking extra than simply these three.
Out of the 67,576 individuals who took the Small Unmanned Plane Check in 2024, the common Half 107 check rating was 79.95%. That’s not even a B.
In the meantime, the go price was 84.2%. (Passing the Half 107 check requires a 70% rating.) Actually, the Half 107 check has among the many worst go charges of any check issued by the FAA. For instance, 91.9% of check takers go the Airplane Non-public Pilot’s Check, and 85.64% go the Airplane Instrument Ranking Check. In accordance with FAA knowledge, the general go price throughout all FAA-issued Airman Information Checks in 2024 was 89.51%. Clearly, drone pilots are bringing the common down.
The best way to keep away from lacking the toughest Half 107 Check questions
These difficult questions illustrate why finding out for the Half 107 check requires greater than only a primary understanding of drones. To spice up your probabilities of success:
✅ Take a Half 107 prep course – On-line programs like Drone Pilot Floor College (which offered the info for this story) and Drone Launch Academy present structured classes, follow exams and professional steerage. Additionally they provide offers. For instance, Drone Pilot Floor College affords an unique low cost for Drone Woman readers to get you $100 off utilizing coupon code DRONEGIRL100.
I personally used Drone Pilot Floor College‘s on-line research course. It labored, as I handed the Half 107 check on my first strive with a 90% rating.
✅ Use follow exams – Determine weak areas earlier than check day with sensible follow questions. Once more, just about any Half 107 on-line course will embody these.
✅ Give attention to difficult subjects – Topics like airspace classifications, climate and Distant ID guidelines are likely to trigger probably the most hassle.
✅ Convey the appropriate supplies – You want your mind energy, however there are additionally some bodily objects it is advisable convey to the Half 107 check. That features a legitimate, government-issued ID.
