I hope that someone can help with the following question. I read the following sentence in an aviation book but need a further explanation why this is:
"In comparison to the true airspeed in still air conditions, the TAS for the best range in a strong tailwind will be slightly lower"
My initial thought was if the wind is behind you would your TAS not be greater? Your groundspeed would be higher as you would have the TAS + windspeed.
