Since aviation safety is at the center of ICAO’s main purposes. Improving aviation’s safety checks while attaining a great level of efficiency, the organization is constantly striving a good collaboration with the air transport community.As airlines are expanding, they are looking way to maximize profits by reducing any possible means of any costs. One of the safety responsibilities ICAO has led to was the birth of the Multi-Crew Pilot License (MPL) training program for their pilot, with the emphasize on a two-man operational decision-making skill. The main safety concern highlighted by ICAO and IATA is, the three most recent decades airline pilots had been trained in single-pilot airplanes to substantially limited crew’s coordination training capability. Even though crew coordination and crew resource management were important training objectives. Comparing to the traditional Commercial Pilot License (CPL) training program after World War 2, The MPL has been proven by ICAO to produce pilot graduate to blend into the multi-crew airline environment much faster time, better work performance and most importantly of all, more cost savings as compared to a CPL/IR holder with a valid type rating. Apart from saving cost, the pilots graduate and check out at a much faster rate to be sited in the right-hand seat. Enabling the airlines to maximize their available resources to meet the stiff and striving competition from their competitor. Most importantly of all, the understudy outlying the main causes of accident rate is due to the pilot error which comes from the study of human factor behavioral and team dynamics of a two-man operation in the cockpit. Hence, ICAO has taken the ways to cut down on “negative solo flying training” on a single engine piston aircraft that has of no relevance to a commercial multi-crew environment operations. Therefore, more time is spent on simulator training environment catered to the MPL cadets instead which also promote in conserving the environment (Alpha Aviation Group., n.d).
