Pre-Flight Procedures & System Checks
This type of checklist is used to ensure nothing is overlooked before a UAS flight.
Pre‑flight checklist
What visual sign on a LiPo battery indicates dangerous battery damage?
Swelling or Puffing of the battery pack
What is the first step in the P.A.S.S. method for using a fire extinguisher?
Pulling the pin
What type of record should be kept for all UAS maintenance and repairs?
UAS Maintenance Record
or
Maintenance Log
What is the optimal temperature range for drone electronics to operate reliably?
Is important because extreme heat or cold can cause sensor errors, reduced battery performance, and even system failure.
Name one thing you should inspect on a drone's propeller before flight.
Answer Will Vary:
Damages - any cracks or chips
Why is it important to check battery voltage levels before a flight?
This ensures the drone has enough power to complete the mission safely without risking an unexpected shutdown.
What federal agency's regulations must always be followed for UAS operations in the United States?
Federal Aviation Administration (FAA)
Why is it important to document even minor issues discovered during inspections?
Small problems have a habit of becoming big, expensive, or dangerous ones if they go unnoticed.
Why is consistent temperature better than fluctuating conditions for UAS electronics?
Thermal stability prevents stress and damage to electronic components
What should you listen for during a motor test to detect potential issues?
Unusual sounds during a motor test, such as grinding, clicking, or irregular buzzing.
What is the recommended state of charge (SoC) for storing LiPo batteries?
State of charge (SoC) for storing LiPo batteries is about 50%–60%
Why is it important to maintain a visual line of sight with your drone during flight?
It allows you to continuously see the aircraft and its surroundings, which is essential for safe operation.
What is one key feature of a proper drone storage facility?
A clean, dry, temperature‑controlled environment.
What can high humidity cause on circuit boards?
Corrosion and short circuits
Why is it important to verify antenna positions during pre-flight checks?
Proper antenna orientation ensures strong, reliable communication between the drone and the controller.
What type of bag should be used for charging lithium polymer batteries to reduce fire risk?
Designed to contain flames, heat, and smoke if a lithium polymer battery fails during charging.
Name one piece of emergency response equipment that should be available during UAS operations.
Answers will vary:
fire extinguisher
What is the benefit of using inventory management systems for drone fleets?
Benefit of tracking equipment, batteries, parts, and maintenance needs accurately and efficiently.
Why should drones be protected from direct sunlight during storage?
Heat and UV exposure can damage sensitive electronics and materials
What is the purpose of checking landing mechanisms (skids or legs) before takeoff?
To ensure the drone can take off and land safely without tipping, collapsing, or damaging its components.
A battery that becomes unusually hot during charging may be experiencing this dangerous condition.
Thermal runaway
What is the purpose of using barriers, signs, or cones at a drone operation site?
Protect people and clearly communicate that an area is restricted or active with drone activity
Why should you use both digital and physical copies for UAS documentation?
Strengthens reliability and keeps your operation protected when something goes wrong.
What is one environmental consideration for personnel working with drones in hot conditions?
Risk of Heat Stress
or
Heat Stroke
