Point of Equal Time (PET)
Hi :)
Could anyone help me to calculate the Point of Equal Time (PET). Here goes the sample: Given: Distance 'A' to 'B' 2346 NM Groundspeed 'out' 365 kt Groundspeed 'back' 480 kt The time from 'A' to the Point of Equal Time (PET) between 'A' and 'B' is: 167 min 290 min 197 min 219 min Thanks in advance!!! |
Basic formula: PET = Distance x GS Home / (GS Home + GS Out)
PET = 2346 x 480 / (480 + 365) PET = 1332,64 NM Since you are interested in time from A to PET, you divide the distance A-PET with GS Out: Time to PET = PET / GS Out = 1332,64 / 365 = 3,65 hours = 219 min |

Thank you, thank you, thank you!!!!!!!!!!!!!!:D
