So if those US airlines exhibit such unprofessional RT why do they have a superior accident record to
any European airline ?
Maybe instead of concentrating on mastering radio pedantry and memorizing a mass of aviation trivia that has no practical value to get an ATPL; mainline US operators want their new hires to show up with a lot of time actually flying an airplane ( the average new hire has 3500 + hrs).......
The US has upped the bar with the requirement that
EVERY airline crew member has a minimum of 1500 hours. At the same time European airlines are racing to adopt the MPL. Zero to right seat jet airliner with passengers and 60 hours of flight time.
