Conveyor belts is the answer, certainly for take off.

Pilot mate for a commercial airline says it would be way to risky in certain places with crosswinds and other reasons.

QuoteNot sure this would work to be honest. Heavier aircraft need higher landing speed, this would result in higher turn radius for a given angle of bank. In order to align with the curved runway on landing, you would inevitably have varying angles of bank according to landing speed - resulting in touchdown on one landing gear first. This isn't ideal and can over stress the landing gear. Not to mention the varying wind as aircraft heading changes. I'll stick with straight runways thanks.

If it became a thing then planes could be engineered to handle the asymmetrical stress -- I don't see that being a deal breaker.  Some of the single engine fighters of WWII were made to offset the rotational stresses of the single prop.  Varying size planes needing different angles could be taken care of by making different tracks for different size planes.

The landing pattern around straight runways is confusing enough. VFR pilots would be SOL. Everything would have to be IFR ...or bots.

Yes haha. Much like if you have to ask if something is ok, it's probably isn't and "with all due respect..." = "no respect"

Yeah, that.

Setting up a crosswind landing is a sphincter-puckering adventure every time you have to do it.  And that's with a straight runway with the apparent wind coming from a steady-ish direction.  Far a 757, approach speeds are 155mph.  On a circular runway, the apparent wind -even if from a steady direction- would be changing at blistering rate.  I'd sure as hell want a bot calculating that and not some sleepy (or drunk) pilot.

Speaking of planes and sphincter-puckering...
