Every fourth pilot in Europe goes to work so tired that it could threaten the safety of the flight": European pilots hide the fact that they are unable to fly a plane safely. "Nearly 7,200 pilots from 32 European countries participated in the survey. 76.8% of them admitted that during the last four weeks they fell asleep at least once involuntarily for a short time - a so-called microsleep - while flying an airplane. Almost half of those surveyed also reported that in the past three months they admitted to working at least once, although they admitted to working at least once. were unable to fly. However, 24.2% of pilots admitted that they continue to fly regularly rather than report being unable to work due to overwork. Almost half of the survey respondents fear negative consequences from airline management if they report fatigue. Less than 12% trust their employers' systems designed to record and manage pilot fatigue."
