While operating your small unmanned aircraft system (sUAS) under Part 107, you suddenly lose the control link with the aircraft, and it begins to fly away from the operation area. What is the BEST immediate action?
medium
During preflight inspection of a small unmanned aircraft system, the remote pilot observes that one of the lithium-polymer batteries is swollen. This condition indicates a high risk of what system failure mode?
hard
Lithium batteries in small unmanned aircraft systems can enter a state of thermal runaway due to factors such as physical damage, overcharging, or manufacturing defects. What is the primary systems-level hazard that results from thermal runaway?
medium
Your small unmanned aircraft system (sUAS) loses the control link and begins flying away uncontrollably (fly-away). What is the BEST immediate action for the remote pilot in command (PIC)?
medium
Which of the following is a recommended best practice for safely charging lithium-polymer batteries used in small unmanned aircraft systems?

A remote pilot is operating a small UAS with a 2.4 GHz control link near a residential building containing multiple Wi-Fi networks and appliances. During execution of emergency procedures, the control link experiences degradation. What is the MOST significant frequency spectrum limitation contributing to this scenario?
medium
A remote pilot is conducting a Part 107 small unmanned aircraft operation using a primary command and control link in the 2.4 GHz spectrum. During the flight, unreliable control is experienced due to radio frequency interference. The small unmanned aircraft system has a backup command and control link in the 433 MHz spectrum, but the remote pilot does not hold an FCC amateur radio license. What is the correct action?
medium
Which of the following frequency spectrums has the associated limitation of requiring an FCC amateur radio license for use in small UAS control link operations?

While operating a small unmanned aircraft 4 statute miles from the nearest suitable landing site, the remote pilot observes 15% battery capacity remaining. The aircraft cruises at 35 miles per hour (mph) and consumes battery at an average rate of 3% per minute. Approximately how much flight time remains before depletion, and what is the MOST APPROPRIATE immediate action per emergency procedures?
