The student pilot may initially struggle to understand the functions of an E6B flight computer. But pilots around the globe rely on this indispensable gadget for charting their flights, crunching numbers to determine time in transit, fuel usage, and necessary adjustments for wind shifts. What Is an E6B and Why Do Pilots Use It?

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 lighting the runway with under 1000 ft to go, the pilots breathed a sigh of relief. C per km (–3.6 °F/1000

On May 1, 2023, a pilot flying his 1979 Beechcraft A36 Bonanza, with two friends on board, was headed to the Big Bear City Airport (L35) to check out a Cessna 150 for sale on the field. And the pilot didn’t plan to land in the open-looking lot, because of a landing gear issue. All pilots have been there. Fuel is not mentioned.

In the early days, pilots used a mechanical circular slide rule, called an E6B. The electronic E6B is equally useful when in the airplane, to help determine actual winds aloft, true airspeed, fuel burn, and descent planning. Calculate the actual true airspeed given the following flight conditions. knots Correct!

A pilot friend and I decided to fly my 1976 Cardinal over to Sedona Airport (KZEZ) for a late lunch. 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. More on that later.

In Defense of the Paper Nav Log Air Facts Journal We’ve all heard the stereotypes about the way age affects the abilities of student pilots. A mid-lifer often shows up equipped with ForeFlight or Garmin Pilot from the start. For a mid-life pilot, this seems like a criminal waste of time. “Those high school kids?

What effect does high density altitude have on aircraft performance? What true airspeed should a pilot expect at 9,000 feet on a standard day with 65 percent maximum continuous power? The result of the interference of the surface of the Earth with the airflow patterns about an airplane. 1,300-foot increase.
