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). As a result, air density at 18,000 ft is roughly half of what it is at the surface, and only around 1/10 at FL500.

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. and read the altitude shown.
