Loading & PerformanceQuestion 88 of 100
During preflight you notice that one of your lithium-polymer battery packs has a slight bulge in its case. What should you do?
a.Fly one short mission with it, then retire the pack after landing
b.Charge the pack to full capacity so the cells reseat before flight
c.Remove the pack from service and follow the manufacturer's disposal guidance
d.Use the pack but raise the low-voltage warning to end the flight sooner
Explanation
A swollen case indicates internal cell damage, and such a pack can lose power without warning or catch fire, so it must be taken out of service and disposed of as the manufacturer directs. Flying it briefly, charging it, or changing the failsafe setting does nothing to repair the damaged cells. Charging a swollen pack is especially hazardous because it adds energy to a failing cell.
