The soaring temperatures that Las Vegas is experiencing this week could cause grief for pilots at other airports, because heat thins the air and makes it more difficult for aircraft to lift at take-off.

On a  warm day a jet will not perform nearly as well as on a cold  day.2 people found this useful.hen the air is colder (it easily gets -40  degrees up there) and the fuel air mixture is burned, the air  expands alot more than if warm air was entering the engine.
