Abstract : Measurement was made of the ability of four groups of pilots to perform a simulated rotary wing approach task under four display conditions of screen size and image field of view on the JANAIR contact analog vertical display. Two screen sizes tested were 6 inch square and 12 inch square. Measures of glideslope altitude, lateral track and airspeed control were recorded during the descent of the approach task. Flare overshoot, impact 'G' and final touchdown position were measured during the landing. Results indicate that image field of view did not differentially affect any of the six performance measures. Approach airspeed control was significantly better with the 12 inch square screen. Final touchdown position control was superior on the 6 inch square screen. None of the remaining performance measures were differentially affected by screen size. It was concluded that pilot subjects with no previous training on the contact analog could adapt to the display condition that each was assigned, but it is recommended that a 1:1 relationship with the real world be used if intermittent VFR-IFR flight were in force or if it were desirable to superposition other information such as television or radar on the contact analog.
