In relation to the current implementations of TCAS,[9] which is intended only for collision avoidance, self-separation requires a leap in processing logic, time anticipation and procedure changes. Its feasibility is dependent on confidence in automation and its co-existence with the human role in the cockpit. Some studies have been conducted to assess this relationship,[10][11] and the results show that the concept is well acceptable from the pilot point of view without imposing unreasonable workload.
