Safety features

Distributed Electric Propulsion (DEP) means having multiple propellers (or electric ducted fans) and multiple electric motors on an aircraft so if one or more propellers (or electric ducted fans) or some electric motors fail, the other working propellers (or electric ducted fans) and electric motors can safely land the aircraft. DEP provides safety through redundancy for its passengers or cargo. There are also redundancies of critical components in the sub-systems of the aircraft providing safety through redundancy for its passengers or cargo. Having multiple redundant systems on any aircraft decreases having any single point of failure. There is also a whole aircraft emergency ballistic parachute in case of an unexpected inflight emergency.
