Density altitude (DA) reduces aircraft performance; it's pressure altitude corrected for nonstandard temperature and humidity. High temperature, humidity, and elevation all contribute to higher DA.

We all deal with engines, so we should know about their relationship with air pressure and density. Query any serious bracket racer, and you'll find he's become a virtual closet meteorologist. What is ...

Pressure altitude is altitude with altimeter set to 29.92" Hg, used for aircraft performance charts above 18,000 ft in US/Canada. Density altitude corrects pressure altitude for temperature; higher ...
