The Rule Of Sixths

摘要

Flight instructors love imparting mnemonic devices, gouges and other memory aids to help their students remember various aeronautical maneuvers and rules. The crosswind gouge known as the Rule of Sixths remains a handy one and works as well as any chart or app, and requires only a functioning brain to work. First, let's calculate the crosswind's angle. Example: Reported winds of 210 degrees at 20 knots, and we'll be using Runway 18.210 minus 180 = 30. The crosswind angle thus is 30 degrees.
