You are conducting a small UAS flight when your weather app alerts you to a nearby thunderstorm producing hail. What is the most significant effect of hail on the aircraft's performance if encountered?

(Refer to Figure 15.) The TAF for KMEM includes PROB40 1220/1222 1SM TSRA OVC008CB. Cumulonimbus (CB) clouds in thunderstorms can produce hail. What is the primary effect of hail on small unmanned aircraft systems (sUAS) performance?

A SIGMET indicates severe thunderstorms with hail within 20 nautical miles of your planned small unmanned aircraft systems (sUAS) flight path. What is the primary hazard posed by hail to the sUAS?

Refer to Figure 12, which depicts Aviation Routine Weather Reports (METARs). The SPECI for KMDW reports RA (rain). If the report had instead indicated GR (hail), what would be the primary effect of hail on small unmanned aircraft systems (sUAS) performance?

Hail encountered by a small unmanned aircraft system (sUAS) in flight will most likely cause
