Abstract: A portable, re-usable, battery-powered, electronic device for storing, displaying and modifying air traffic control information. The electronic flight data strip receives input data from an external data source via infrared or radio transmission, stores the data in an on-board memory device, displays selected portions of the received data for viewing by an air traffic controller, and receives and displays inputs from the air traffic controller either directly through integral switches or via aforesaid communications channels. All input and output data messages and air traffic controller commands may be stored and time tagged for later retrieval. The contents of the stored memory can also be interrogated and modified by external data processing devices. Following completion of the flight, the contents of the internal memory can be interrogated for the purpose of archiving or investigation and/or cleared for subsequent re-use on another flight.
