A lithium-polymer battery for a small unmanned aircraft has a rated capacity of 2200 milliampere-hours (mAh). For safe usage, what is the maximum continuous charging current using the manufacturer-recommended 1C charge rate?

During preflight inspection of your small unmanned aircraft system (sUAS), you notice the lithium-polymer battery appears swollen. Applying safe usage procedures for lithium batteries, what is the required action?

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?

Which of the following is a recommended practice for safely charging lithium-polymer batteries used in small unmanned aircraft systems (sUAS)?

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?

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)?

Which of the following is a recommended best practice for safely charging lithium-polymer batteries used in small unmanned aircraft systems?

During operation of a small unmanned aircraft system (sUAS), a lithium-polymer battery sustains internal damage leading to initial overheating in one cell. What is the primary risk that could cause the fire to propagate uncontrollably through the entire battery pack?

What is a primary risk associated with fires involving lithium batteries used in small unmanned aircraft systems?

Refer to the following excerpt from an sUAS emergency procedures chart: ``` ┌──────────────────────┬──────────────────────┬──────────────────────┐ │ Emergency │ Primary Action │ Secondary Action │ ├──────────────────────┼──────────────────────┼──────────────────────┤ │ Loss of Control Link │ Attempt to regain │ Activate failsafe or │ │ │ control │ return-to-home │ ├──────────────────────┼──────────────────────┼──────────────────────┤ │ Fly-Away │ Activate return-to- │ Monitor and │ │ │ home (RTH) │ report position │ └──────────────────────┴──────────────────────┴──────────────────────┘ ``` What is the primary action for loss of aircraft control link?

During preflight preparations for your small unmanned aircraft operation, you observe that the lithium-polymer battery pack appears swollen. According to safe usage practices, what should you do?

For safe transportation of lithium batteries used in small unmanned aircraft systems, what must the remote pilot in command ensure?

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?
