Pilot Performance in Trajectory-Based Operations Under Concepts of Operation That Vary Separation Responsibility


Kim-Phuong, Strybela, Battisteb, Lachterb, Daob, Brandtb, Ligdab & Johnsonc conducted a research in 2012 to understand how NexGen will impact human factors automation across pilots and air traffic controllers. The data aliased in the article is pilot performance, workload, and situation awareness under one of the three plausible NextGen concepts of operation. This wiki page realises and summarises of the article to show in a clear, readable display.

Research approach


The sample size was sixteen pilots of which participated in the simulation. Of the two weeks of testing, 13 were captains and 3 were first officers. Of the two week research, 8 pilots were tested each week. In 2011, 120,865 was estimated of US certified commercial pilots, meaning a sample size of 0.0132379 of the total population according to FAA. All participants had no prior experience with interval management procedures. Four retired radar-certified ATCs participated and two of the four participated each week. Experience of ATC ranged from 25 – 35 years’ experience.


The simulation environment was assessed by Multiple Aircraft Control System (MACS), which is a software developed by NASA. The cockpit situational display (CSD) software.
