What does a healthy throttle margin at hover tell the pilot?

• A.The aircraft can be flown in any wind without concern
• B.Spare power remains available for climbs, maneuvers, and gust corrections
• C.The battery is fully charged

Why

An aircraft that hovers well below full throttle has reserve thrust for the unexpected. Little or no margin at hover is a warning to land, lighten the load, or wait for better conditions.
