Type	Description
list[CheckResult]	List of :class:CheckResult instances (one per check).

Result of a single preflight check on one drone.

EMERGENCY: Command all drones to land immediately (controlled descent).

This is the default emergency action -- drones descend under flight- controller control, which is safer than a motor kill.

EMERGENCY: Force disarm ALL motors immediately.

Drones will fall from the sky. This is a LAST RESORT. Requires confirm=True to prevent accidental invocation.
