Flying to the Mid-East takes 6 hours, the return flight is 7 hours.
Now I know that aircraft are always susceptible to the speed of air around them. So if you have a 100 MPH tailwind theoretically you gain an extra 100 MPH relative to ground travel.
I have done a 50 minute Gatwick-Inverness flight which usually takes 1 hr 30 on a Bae 146 but for an 140 MPH tailwind.
However movement of air may follow patterns but there is no guarantee eitherway of a headwind or a tailwind. It’s just something that happens when the weather feels like doing it.
Air is though subject to the same gravitational forces as we humans. So does it automatically create a headwind when you fly counter-rotation and a tailwind when with rotation?
Is this why the outbound flight is an hour shorter than the inbound?
