ATPL: Given:X = Distance A to point of equal time (PET) between A and B E = EnduranceD = Distance A to B O = Groundspeed 'on'H = Groundspeed 'back'The formula for calculating the distance X to point of equal time (PET) is:
Domanda 155, Flight Planning and Monitoring - ATPL - Airline Transport Pilot license
| X = D x H / (O + H) |
| X = D x O x H / (O + H) |
| X = E x H / (O + H) |
| X = D x O / (O + H) |
