There are three primary sources of ATP which, in order of their utilization, are creatine phosphate (CP), anaerobic glycolysis, and oxidative phosphorylation. Energy from ATP derives from cleaving of the terminal phosphate of the ATP molecule.
Under the new rules, pilots will be able to be on duty for nine to 14 hours â a number that will fluctuate based on factors such as when the pilotâs day begins and how many segments he or she will fly in one day. Pilots will be able to fly no more than nine hours during that period.
Under the new rules, pilots could be landing commercial jets after 22 hours awake - including 11 hours flying, plus stand-by time and travel to the airport. Under the current UK rules, pilots work a maximum of three early starts in a row and a maximum of 95 hours in 14 days. EASA is proposing to change this to seven early starts in a row and a maximum of 110 hours in 14 days.
