Why do helicopters/choppers need to do circles in the air before landing?
In: Engineering
uh?
they dont, at least not for any major technical reason. if anything a a practice for pilots to survey the landing Area to make sure its clear.
there is a small technical aspect they might wanna do this but its not major unless its an emergency, since its merely the fact the helicopter is setup in a way there the pilot has a lil more mobility when moving forward than if they just hover down so they might circle around while descending, this is by on means necessary but it speeds up the landing process.
