Abstract

A team of subject matter experts (SMEs) observed tower air traffic controllers as they marked flight progress strips (FPSs) at ten facilities. SMEs tallied marks and actions controllers made at various positions during 332 twentyminute observation periods. During many of the observation periods, one or more marks or actions were targeted for interviews. The benefits controllers perceived from making the targeted mark or action varied across position. The findings from this study will help engineers preserve the functional benefits received from paper FPS when designing electronic FPSs.
