Density altitude (DA) is a critical factor affecting aircraft performance, often misunderstood by pilots as an automatic flight cancellation; instead, it indicates reduced air density due to high ...

Density altitude, influenced by high temperatures, humidity, or high elevation, significantly degrades aircraft performance by increasing takeoff/landing distances and reducing climb rate. Pilots must ...

Has density altitude affected your flight plans recently? Do you plan for it when you create those summertime flight plans? I ask because as I write this column Seattle is under a heat advisory.
