Point of
Equal Time (PET) = (Distance x Homeward Groundspeed) / (Outbound Groundspeed +
Homeward Groundspeed)
TAS = 470 KTAS
Outbound Groundspeed = 470 + 55 knots Wind Component = 525 knots
Homeward Groundspeed = 470 - 75 knots Wind Component = 395 knots
PET = (D x H) / (O + H)
PET = (2,900 x 395) / (525 + 395)
PET = 1,145,500 / 920
PET = 1,245 NM (from Departure Point)
Outbound Groundspeed = 525 knots
Therefore, time to PET at 1,245 NM = 1,245 / 525 = 2.37 hours = 2 hours 22
minutes
14:35 + 02:22 = 16:57
