You're the professional pilot - you tell me. Your skills are assessed both in the sim and on the line - are you telling me that you cannot possibly rate one above another by rating the skills required to be demonstrated?
The skills we are required to maintain are those that have been established by our respective governmental aviation authorities, administered and overseen by our company training departments.
The frequent assessments we all go through on the line and in the sim are designed to ensure we maintain these skills, not how much ‘right stuff’ in excess of the standard each one of us may or may not have. You seem to suggest we should all be assessed to the maximum limits of our abilities in order to determine who should, or should not, be promoted.
Re-Heat, it would help all of us if you could clarify your background; are you an HR person, a pilot, a senior manager, a business studies major?
