I suppose the answer is yes sometimes.
Good Pilots already are good managers by definition. Managing the day to day affairs of their employers interests to the best of their ability. Organising and coordinating a team of people who in turn are responsible back to the manager for the safe and efficient operation of the business. making executive decisions based on input from multiple sources.
All of these make the good Pilot a good candidate for other managerial positions in my opinion. Outside of the Aircraft it would be necessary to learn addition skills, so I suppose the good manager would be flexible and willing to listen and learn.
It doesn't sound to me as if Pilots would not make good managers in other situations, but it would depend on the suitability of the person for the position on offer. That decision would ultimately rest with with a more senior appointee.
Courses and other assistance would be very important for a new manager. Time to learn and settle in to the new position is also important. Just like being a Pilot really !
