Jun 6, 2020 at 6:43 comment added Peter Kämpf @quietflyer. Wouldn't that make the question meaningless? When it's about propeller aircraft, the prop should do the lifting.
Jun 5, 2020 at 22:42 comment added quiet flyer Is the question meant to exclude situations where meteorological "lift" such as mountain wave assists the aircraft in climbing to high altitude?

Nov 15, 2016 at 15:37 comment added UIDAlexD @TannerSwett Sorry for replying to such an old post, but I wanted to say that Orbital Mechanics is bizarrely counter-intuitive. In order to reach a high, slow-speed orbit you need to accelerate to put energy into your orbit. Inversely, to move from a high-altitude low-speed orbit to a high-speed low-altitude one, you have to decelerate and remove energy from your orbit. Slowing down is speeding up and speeding up is slowing down. Crazy, right?
Sep 18, 2016 at 7:21 comment added Peter Kämpf @TannerSwett What I meant is that you need to start with a higher velocity in order to reach the higher orbit. I admit that was not expressed clearly. I hope my edit improved the answer.

Sep 18, 2016 at 4:36 comment added Sophie Swett "The higher the orbit becomes, the faster the aircraft needs to go." – Other way around, isn't it? For circular orbits, the orbital velocity is slower the higher up you go.
