Practice Questions for the UAS Test

Practice Questions for the UAS Test

Studying for the Unmanned Aircraft System (UAS) test can be daunting. However, familiarizing yourself with the type of questions that are typically asked can make the process smoother. Questions often cover diverse topics, including regulations, meteorology, and operational procedures. Here are some practice questions to help you prepare.

FAA Regulations

The FAA has strict regulations for operating UAS. Compliance is mandatory.

• What is the maximum altitude permitted for flying a UAS under Part 107?
  • 400 feet above ground level (AGL)
• In which situations are you allowed to fly beyond visual line of sight?
  • Under no circumstances unless you have a waiver from the FAA
• What is the minimum visibility required to operate a UAS?
  • 3 miles
• How far should you stay away from airports without ATC authorization?
  • At least 5 miles
• When must a UAS be registered with the FAA?
  • If the drone weighs 0.55 pounds or more

Meteorology

Understanding weather conditions is crucial for safe UAS operations.

• What are the effects of high-density altitude on a UAS?
  • Reduced performance and longer takeoff distances
• Why is it important to understand the concepts of stable vs. unstable air?
  • To predict weather conditions such as turbulence and cloud formations
• How do you determine wind direction and speed before a flight?
  • Using weather reports and observing environmental indicators like smoke or leaves

Operational Procedures

Effective operational procedures ensure that UAS flights are safe and lawful.

• What should you include in a pre-flight checklist?
  • Battery check, propeller inspection, control calibration, GPS signal verification
• Why is it important to perform a site survey before flight?
  • To identify potential hazards and assess the environment
• How do you manage a lost-link situation?
  • Program the UAS to return to home or hover until the link is re-established
• What steps should you follow if you encounter an emergency during flight?
  • Land as soon as possible, notify relevant authorities, assess the situation

Aircraft Performance

Knowledge of aircraft performance can prevent accidents and improve flight efficiency.

• How does weight affect UAS performance?
  • Increased weight reduces maneuverability and flight time
• What is the significance of the center of gravity on a UAS?
  • A properly balanced center of gravity ensures stable flight
• How does battery performance impact flight?
  • Low battery levels can shorten flight duration and increase the risk of crashes

Emergency Procedures

Being prepared for emergencies can mitigate risks and potential damage.

• What actions should be taken if you experience a flyaway?
  • Attempt to regain control, activate return-to-home functionality, alert authorities if necessary
• What are the first steps if a UAS crashes?
  • Ensure safety of people, retrieve the UAS if safe, document the incident

Understanding Airspace

Knowledge of different airspace classifications helps in planning safe flights.

• What are the characteristics of Class G airspace?
  • It is uncontrolled, and operations are allowed up to 400 feet AGL
• How do you obtain authorization to operate in controlled airspace?
  • Submit a request through the FAA’s LAANC system or file a paper application
