TZ SMArt Devices™ can significantly improve security and access to line replaceable units. Access to specific areas of the aircraft can be linked to work orders. Electronic latches provide an audit trail that can reduce the labor involved in manual paper-based inspection processes. Access to sensitive areas of the aircraft — areas like the engine nacelle — can be authorized only to specific people. Electronic latching is faster than conventional latching and can be completely internal — improving the streamlined effect of the aircraft fuselage.
