    Evidence: "7. COMMUNICATIONS AND NEW TECHNOLOGY ... Primary Flight Display (PFD) The former electromechanical instruments had an inherent lack of flexibility because of the physical necessity to spread information on several instruments of the pilot's panels. The successor to the ADI [Altitude Direction Indicator], the PFD is basically used for short term flight path monitoring and at first glance it shows the aircraft aerodynamic situation i.e. attitude, speed and status of guidance system. Communication to the crew of the main parameters displayed on the same full colour, shadow mask, high resolution EFIS CRT reduces the need to scan a large area of instruments, but without concentrating the information to the 'hypnosis point'. Crew mental workload was shown to be reduced by the new, more direct process of information assimilation" (page 7)
