TZ SMArt Devices™ can significantly improve aviation security, airplane maintenance, and access to line replaceable units. These electronic smart locks can be configured to allow for access to specific areas of the aircraft to be linked with 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 through a TZ aerospace smart lock system is faster than conventional latching and can be completely internal — improving the streamlined effect of the aircraft fuselage.
