Editing Hot and high (section)

==Negative effects of reduced engine power due to hot and high conditions==
* Airplanes require a longer takeoff run, potentially exceeding the amount of available runway.
* Reduced take-off power hampers an aircraft's ability to climb. In some cases, an aircraft may be unable to climb rapidly enough to clear terrain surrounding a mountain airport.
* Helicopters may be forced to operate in the shaded portion of the [[height-velocity diagram]] in order to become airborne at all. This creates the potential for an uncontrollable descent in the event of an engine failure.
* In some cases, aircraft have landed at high-altitude airports by taking advantage of cold temperatures only to become stranded as temperatures warmed and air density decreased.
* While unsafe at any altitude, an overloaded aircraft is much more dangerous under hot and high conditions.
