By Karsten Shein Comm-Inst Climate Scientist QNE, QNH, and QFE describe different altitudes for different phases of flight, but also serve as pressure altitude (QNE) or density altitude (QNH). A discussion of air density is one that may cause some to tune out, thinking it dull.

You can also use it for unit conversions, estimating wind correction angles, and figuring out density altitude. Using the Air Density Windows and the Baseplate The disk also features cut-out windows designed for air density-related calculations. and read the altitude shown. Thats your true airspeed.

After a shallow turn from downwind, the Bonanza was positioned on base at a proper altitude and airspeed and with a constant descent rate. NTSB weather data analysis determined the wind at 7,500 feet (about 700 feet above the runway) was from 210 degrees at 17 knots—a healthy tailwind for base leg.

The Cardinal and I were fairly new to the area, but I respected its performance limitations and was careful to account for the elevation and temperature and the density altitude it would surely bring. So, what was a pilot new to the high and hot world of density altitude flying to do? More on that later. It all adds up.

Winds on the surface, and winds at altitude: both concepts are covered in the nav-log lesson. Isn’t it interesting to know that based partly on measurements from weather balloons, you can predict the way the winds aloft are going to cause your plane to drift as you fly from point to point, and that you can correct for that as you fly?

Key Takeaways Air density affects aircraft performance, including lift, engine power, and propeller effectiveness. Factors influencing air density include altitude, temperature, pressure, and humidity. High-density altitude reduces aircraft performance, requiring flight adjustments. What Is Air Density?

It was easy enough to avoid Oakland and San Francisco Terminal Control Areas, now Class B, but Bay Area weather was completely different from New England. Otherwise, the standard weather forecast is “rain turning to showers, chance of sun breaks.” On the East Coast, the ocean is east, but on the West Coast, it is west.
