What may be used to assist compliance with being able to maintain situational awareness as a remote PIC?
a. First-person view camera
b. Remote PIC diligence
c. Binoculars
Binoculars (Correct Answer)
To comply with See and Avoid requirements, a Remote PIC cannot use a first-person view camera or binoculars to assist. Only a Remote PIC’s diligence, or own natural unaided eyesight efforts (glasses and contacts are OK) can be used.
Binoculars CAN be used to assist with basic situational awareness, though
(Refer to Figure 78) Identify the airspace over Onawa airport (K36).
A. Class G airspace - surface up to but not including 18,000 feet MSL.
B. Class G airspace - surface up to but not including 700 feet MSL, Class E airspace - 700 feet to 14,500 feet MSL.
C. Class G airspace - surface up to but not including 1,200 feet AGL, Class E airspace - 1,200 feet AGL up to but not including 18,000 feet MSL.
Class G airspace - surface up to but not including 1,200 feet AGL, Class E airspace - 1,200 feet AGL up to but not including 18,000 feet MSL.
Feedback
Onawa airport (K36) airport sits in Class G airspace. The thing to remember in this question is that while the airport sits in Class G airspace, how high does that Class G airspace go up to? Where does it turn into Class E airspace? Remember that unless it is marked otherwise, Class E airspace usually starts at 1,200 ft. AGL
You have received an outlook briefing from flight service through 1800wxbrief.com. The briefing indicates you can expect a low-level temperature inversion with high relative humidity. What weather conditions would you expect?
a. Smooth air, poor visibility, fog, haze, or low clouds.
b. Light wind shear, poor visibility, haze, and light rain.
c. Turbulent air, poor visibility, fog, low stratus type clouds, and showery precipitation.
Smooth air, poor visibility, fog, haze, or low clouds. (Correct Answer)
Feedback
A temperature inversion exists where there is an increase in temperature as altitude is increased. The air is stable, so you can expect smooth air and poor visibility due to fog, haze, or low clouds. The most frequent type of ground-based inversion is that produced by terrestrial radiation on a clear, relatively still night.
(Refer to Figure 59, area 1.) You’re hired to inspect a tower by Lenawee County airport (ADG). Which radio frequency would you tune into to listen to manned aircraft chatter from incoming or outgoing pilots?
A. 118.375
B. 118.75
C. 122.8
C. 122.8
The radio frequency that sUAS operators can tune into to listen to manned aircraft chatter from incoming or outgoing pilots is called the Common Traffic
Advisory Frequency (CTAF).
On a Sectional Chart, it’ll actually say what CTAF frequency you should be using. Just look for the C / Circle symbol, and the CTAF frequency will be right before it. The CTAF frequency is always going to be to the left of the circle C icon. In the legend section above, the CTAF frequency is also the CT or Control Tower frequency, and it is 118.3.
In this question, the CTAF frequency at Lenawee County airport (ADG) is 122.8
(Refer to Figure 25, area 8. What airspace would you be operating in if flying at the maximum allowable altitude while inspecting the towers 9 statute miles SW of Dallas Executive airport (RBD)?
Class D
Class E
Class G
Class E
This is one of the most complicated Sectional Chart excerpts you’ll encounter. It’s crowded and difficult to interpret. Take your time to first identify where Dallas Executive airport is located. While the Part 107 regulations state a maximum altitude of 400 ft. AGL, you’re allowed to fly higher than that as long as you’re within 400 ft. of a tower/obstruction. You’re even allowed to fly up to 400 ft. over the topmost part of that tower. In this case, the height of the towers 9 statute miles SW of Dallas Executive Airport (RBD) is 2,549 ft. MSL / 1,731 ft. AGL. If you’re flying “at the maximum allowable altitude,” you’d be flying 2,549 ft. MSL + 400 ft., or 2,949 ft. MSL. In AGL, you’d be flying 1,731 ft. AGL + 400 ft., or 2,131 ft. AGL.
So, is there controlled airspace at this height? There’s no Class D or Class E at surface airspace being indicated where the tower sits, so let’s look to the blue solid lines indicating Class B airspace.
In this closed-off part of Class B airspace, we see a fraction that says 110/30, meaning that the Class B controlled airspace doesn’t start until 3,000 ft. MSL.
But at 2,949 ft. MSL, you’re flying about 50 ft. below that, so you’re not in Class B.
Remember that coming up from the surface unless it’s otherwise marked, you have Class G uncontrolled airspace going up to either 700 ft. AGL or 1,200 ft.
AGL. Then you have Class E controlled airspace. So when you’re flying at 2,949 ft. MSL / 2,131 ft. AGL, you’re in Class E.
Remember that the airspace classes can stack on top of each other! So in this case, from the surface, it’s Class G, then E, then B. This is one of the trickiest questions in our program.

(Refer to Figure 26, area 2.) You’ve been asked to inspect the tower 4 to 5 statute miles northwest of Cooperstown airport (S32). How high must the cloud base be for you to be able to fly the maximum allowable height over the tower?
650 ft. AGL
700 ft. AGL
1,150 ft. AGL
1,150 ft. AGL
Feedback
This is a complex question! First, let’s address what the “maximum allowable height over the tower” means. While the Part 107 regulations state a maximum altitude of 400 ft. AGL, you’re allowed to fly higher than that as long as you’re within 400 ft. of a tower / obstruction. You’re even allowed to fly up to 400 ft. over the topmost part of that tower. In this case, the tower 4 to 5 statute miles northwest of Cooperstown airport (S32) is 250 ft. AGL. If you’re flying “as high as allowed under Part 107,” you’d be flying 250 ft. AGL + 400 ft., or 650 ft. AGL.
So if you’re flying at 650 ft. AGL, how high must the cloud base be for that flight to be possible? Remember that you need to be flying at least 500 ft. from the cloud base, so you can add 500 ft. to 650 ft. to get 1,150 ft. AGL. The cloud base needs to be at least 1,150 ft. AGL, otherwise you’d be violating the cloud clearance regulation of at least 500 ft. when flying over the top of the tower.
(Refer to FAA-CT-8080-2H, Figure 23) What’s the lower altitude limit of Class E airspace at Statesboro Bulloch County Airport (TBR)?
887 ft. MSL
700 ft. MSL
1,200 f. MSL
Feedback
See how Statesboro Bulloch County Airport (TBR) is located inside the magenta vignette / fuzzy line? Remember that within those lines Class E starts at 700 ft. AGL. Not MSL, but AGL.
Looking at the section of text next to the airport icon, specifically the bottom line where it says 187 *L 60-122.8 C, We know the MSL height of the airport is 187 feet. Meaning that if you’re standing on the runway of the airport, you’re at 187 feet mean sea level.
So because you know this, you can add 700 ft. AGL to get to 887 feet MSL. The correct answer is 887 feet MSL. The correct answer also could have been 700 ft. AGL, but that wasn’t listed as an answer choice. The trick is to understand the difference between MSL and AGL and how they relate to each other, and not to get tripped up like many students do with answer choice B where it says 700 ft. MSL.
887 ft. MSL

According to 14 CFR Part 48, when must a person register a small UA with the Federal Aviation Administration?
a. Only if the small UAs is flown within controlled airspace.
b. When the small UA is used for any purpose other than as a model aircraft.
c. Only when the operator will be paid for commercial services.
Feedback
In this question, “model aircraft” represents recreational drone use. Non-recreational drone use would be like taking photos to help sell a property or service, roof inspections, taking pictures of a high school football game for the school’s website, or volunteering to use your drone to survey coastlines on behalf of a non-profit organization. Flying a drone for any kind of non-recreational purpose requires registration, regardless of the drone’s weight.
