Well said, Panama. Airlines are supposed to hire pilots whom they see flying as captains sometime in the future. When so few people make it through the process does that mean the recruiting department is failing in its job to find qualified applicants?
The captain assessment process is a waste of time and money for the company. The fact that so many people do not succeed during upgrade training also reflects poorly on the training department. They are supposed to be preparing the candidates to be safe, competent captains for the airline. Not 20-year first officers.
