Airspace & Charts
What is the maximum altitude allowed under Part 107 without a waiver?
400 feet AGL
What is the minimum visibility requirement for Part 107 flights?
3 statute miles
What is the minimum age to get a Part 107 certificate?
16 years old
If you lose control link to the drone, what should it do?
Follow programmed lost-link procedure (usually RTH)
What’s the maximum weight a drone can be to fly under Part 107?
Less than 55 lbs (including payload)
Which class of airspace surrounds the busiest airports, such as ATL or LAX?
Class B
What is 500 feet?
When there are clouds present, your aircraft must maintain at least this distance below them.
How often must you pass the recurrent knowledge test?
Every 24 months
Who is responsible for the safe operation of the UAS?
The Remote PIC
What is density altitude?
As this altitude increases, the performance of your aircraft decreases due to thinner air.
On a sectional chart, what does a solid magenta line around an airport indicate?
Class C airspace boundary
What is density altitude?
This altitude represents how your aircraft "feels" like it's flying based on air density conditions.
What is the maximum groundspeed allowed under Part 107?
100 mph (87 knots)
Can you fly over people under Part 107?
Only with Category 1–4 compliance or waiver
What is a stall?
This occurs when the smooth airflow over the unmanned airplane's wing is disrupted and lift degenerates rapidly.
What must you receive before operating in Class D airspace?
ATC authorization
What is a temperature inversion?
In this atmospheric condition, air is stable and smooth, but visibility is poor due to fog, haze, or low clouds
Under Part 107, when may a Remote PIC operate a small UAS from a moving land vehicle?
Only if flying over a sparsely populated area and not transporting property for compensation or hire.
What is the correct first step after a flyaway incident?
Maintain visual contact if possible and follow emergency procedures; notify ATC immediately if in controlled airspace or if aircraft poses hazard to other aircraft
What is the critical angle of attack?
When this is exceeded, the smooth airflow over the UA's wing will be disrupted and a stall can occur.
Which tool is best for checking UAS facility maps and LAANC requests?
FAA Drone Zone or LAANC app
What are cumulonimbus clouds?
These clouds are the most dangerous type for pilots and are produced by thunderstorms.
What is the blood alcohol content limit for Part 107 pilots?
0.04%
If you accidentally damage property during flight, what must you do?
Report to the FAA within 10 days if injury or >$500 damage
What is the Pilot's Operating Handbook or UAS Flight Manual?
To ensure unmanned aircraft center of gravity limits are not exceeded, you should follow the instructions in this document.
