The Saab-BAe multi-role fighter aircraft Gripen has a continuos development program to incorporate new technology. Current important cockpit changes are the replacement of the three 5´´x6´´ monochrome CRT displays by three 6´´x8´´ Color Multi-Function Displays (CMFD), and the removal of the traditional and dedicated electromechanical stand-by flight data instruments. One important aim of introducing the new 6"x8" CMFDs in the Gripen aircraft is to use them all for full screen presentation of tactical information. The size of the displays disables the use of self-contained stand-by instruments, why these instruments will be deleted. As a consequence a new concept for displaying flight data has been developed. The concept comprises of automated flight data monitoring and functions for immediate head down presentation of flight data when necessary. To achieve this, system safety considerations must be a vital part of all steps in the design and partly new principles has been used to ensure system safety and the performance of the supervision functionality for cross comparing the ordinary to stand-by flight data.
