There have been issues with South Korean military pilots moving to the commercial World. Its not a one-off affair. The fear of challenging a superior is a known traits and that comes form the military back ground. In the case of our Silk Air pilot, he had chalked up a series of breaches. He should not have been allowed to fly. The demotion did nothing to save the lives of innocent passengers.
Almost all the ex air force pilots make the grade when they move on from military to commercial flying. Some find the transition easier than others and many are doing well as instructors and management pilots. Their military flying whether fighters or transport, develops their handling skills and being in the forces they usually have and display good leadership qualities.
They need to learn how to manage the automation in the cockpit and work well together with their partner in the cockpit. They also need to pick up a different perspective of safety mindedness in relation to schedule pressures. Most do so fairly easily because along with their leadership qualities as mentioned, they also have maturity.
So all in all yes, ex airforce pilots usually end up as good commercial pilots.
