Abstract
An aircraft control and display system having a multifunction display for configuring the vehicle flight parameters and control of mission equipment utilizes a dedicated alphanumeric display as a scratchpad memory for temporarily displaying IFF mode commands encoded in alphanumeric form and for changing an IFF transponder code, thereby obviating the use of the multifunction display and the need thereby for reprogramming the mission functions. Codes entered in the alphanumeric display are validated against codes stored in a master control processor unit, whereby a prompt is provided to the operator to reenter the code in the event of an error in entry or an invalid code.
