The toughest Half 107 check questions — and find out how to get them proper

The Federal Aviation Administration’s Half 107 check is an important step for anybody aiming to turn out to be a licensed drone pilot for business operations within the U.S. Some questions are fairly simple, the place a dose of widespread sense may resolve them. However different questions are usually not simply troublesome except you’ve critically studied — however they’re nearly deliberately tough. So of these, what are probably the most missed — or let’s assume hardest Half 107 check questions?

I reached out to my mates at Drone Pilot Floor Faculty, which has been providing on-line Half 107 check prep programs ever since 2016. Their program gives 5, full-length observe assessments that mirror the actual examination format. These assessments come from a financial institution of greater than 400 pattern questions from the FAA.

While you full the observe check, Drone Pilot Floor Faculty sends over a efficiency report and breakdown of your incorrect responses. Provided that, they’ve a robust knowledge set of the Half 107 check questions which might be missed probably the most.

They shared these questions with me. And together with that, Drone Pilot Floor Faculty Buyer Success Supervisor Michael McGuirt added is personal perception on why they’re so tough — and why the proper 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 correct reply:

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 stress
C) The barometric stress 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 stated.

However understanding the connection between temperature and dew level is vital to figuring out when and the place clouds will type.

Rationalization: “The distinction between the floor temperature and the dew level temperature determines the altitude at which the air cools to its saturation level,” McGuirt stated. “This altitude is the place clouds start to type.”

• A small distinction (3-5º) between temperature and dew level ends in a low cloud base, because the air doesn’t have to rise far to condense.    
• A giant 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 numerous climate apps equivalent to 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 toes 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 sort 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 stated. “However the one sort of Class E that requires an airspace authorization is Floor Space Class E.”

Rationalization: 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 an ordinary Distant ID unmanned plane in line with § 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 commonly missed as a result of college students haven’t dedicated to reminiscence all the parts of the Distant ID Broadcast message,” McGuirt stated.

Rationalization: There are eight parts that you need to decide to reminiscence.

1. A serial quantity or session ID
2. Latitude and longitude of the management station
3. Geometric altitude of the management station
4. Latitude and longitude of the plane
5. Geometric altitude of the plane
6. The rate of the plane
7. A timestamp in Coordinated Common Time (UTC)
8. The emergency standing of the plane

Discover that battery degree is NOT a required ingredient—a typical false impression amongst test-takers.

Be ready — as a result of check scores aren’t nice

When you thought these questions have been troublesome, you’re not alone. For what it’s value, 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 Take a look at in 2024, the common Half 107 check rating was 79.95%. That’s not even a B.

In the meantime, the cross fee was 84.2%. (Passing the Half 107 check requires a 70% rating.) In reality, the Half 107 check has among the many worst cross charges of any check issued by the FAA. For instance, 91.9% of check takers cross the Airplane Non-public Pilot’s Take a look at, and 85.64% cross the Airplane Instrument Score Take a look at. In accordance with FAA knowledge, the general cross fee throughout all FAA-issued Airman Information Assessments in 2024 was 89.51%. Clearly, drone pilots are bringing the typical down.

keep away from lacking the toughest Half 107 Take a look at questions

These tough questions illustrate why finding out for the Half 107 check requires greater than only a fundamental understanding of drones. To spice up your possibilities of success:

✅ Take a Half 107 prep course – On-line programs like Drone Pilot Floor Faculty (which offered the info for this story) and Drone Launch Academy present structured classes, observe assessments and knowledgeable steering. In addition they supply offers. For instance, Drone Pilot Floor Faculty gives an unique low cost for Drone Woman readers to get you $100 off utilizing coupon code DRONEGIRL100. 

I personally used Drone Pilot Floor Faculty‘s on-line research course. It labored, as I handed the Half 107 check on my first attempt with a 90% rating.

✅ Use observe assessments – Determine weak areas earlier than check day with sensible observe questions. Once more, just about any Half 107 on-line course will embrace these.

✅ Concentrate on tough matters – Topics like airspace classifications, climate and Distant ID guidelines are inclined to trigger probably the most hassle.

✅ Carry the correct supplies – You want your mind energy, however there are additionally some bodily gadgets you want to convey to the Half 107 check. That features a legitimate, government-issued ID.
