Negative Effects of Hot and High Conditions
- Airplanes require a longer takeoff run, potentially exceeding the amount of available runway.
- Low air density 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.
- Some aircraft, particularly light general aviation airplanes and older helicopters, have service ceilings so low that they may stall simply trying to maintain level flight. 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.

“The working woman may be quick to see any problems with children as her fault because she isn’t as available to them. However, the fact that she is employed is rarely central to the conflict. And overall, studies show, being employed doesn’t have negative effects on children; carefully done research consistently makes this clear.”
—Grace Baruch (20th century)

His serpent’s track went up the hill forever.

And cold as any icicle.”

“And hearts that once beat high for praise
Now feel that pulse no more!”
—Thomas Moore (1779–1852)
“A society which is clamoring for choice, which is filled with many articulate groups, each urging its own brand of salvation, its own variety of economic philosophy, will give each new generation no peace until all have chosen or gone under, unable to bear the conditions of choice. The stress is in our civilization.”
—Margaret Mead (1901–1978)
