ABSTRACT:
An automatic data input/output system has combined card reading and recording device features which permit a pilot to totally utilize same as part of an aircraft navigation system. A small light weight drive system is incorporated within the device to move the magnetic card with respect to the read-write heads.
The operational modes of the system include a MONITOR MODE, a RECORD MODE, an ENTER MODE, and an ERROR MODE. This permits a pilot to encode or record navigational data on a magnetic card or read the data from the card and automatically input same to a device for assisting in the navigation of the aircraft. The ERROR MODE provides a means for checking the data as read from the card to insure the accuracy of same before it can be used by the navigational device.
