The E6B is an analog circular slide rule and navigation computer developed by US Navy Lieutenant Philip Dalton in the 1930s. Its name originates from its original part number for the US Army Air Corps during WWII.
Look at the pencil mark to see how many degrees left or right it sits from the centerline. This is your Wind Correction Angle (WCA). Because the wind is from the right ( 180∘180 raised to the composed with power ), you must crab into it. Wind Correction Angle: +10∘positive 10 raised to the composed with power True Heading: 100∘100 raised to the composed with power Groundspeed: 118 Knots. Exercise 7: Heading with a Tailwind Component Scenario: True Course (TC): 340∘340 raised to the composed with power True Airspeed (TAS): 100 knots Wind Direction/Speed: From 290∘290 raised to the composed with power at 25 knots E6B Steps: 290∘290 raised to the composed with power with the True Index. Mark 25 knots up from the grommet. Turn the wheel to put 340∘340 raised to the composed with power under the True Index.

: Physical units from ASA or Sporty's are standard for FAA exams, with the electronic versions often featuring backlit screens and built-in storage cases for turbulence. Sporty's Pilot Training - App Store The E6B is an analog circular slide rule
When using the wind side, a thick pen marker can introduce a 2-to-3-knot or degree error. Use a fine-tip mechanical pencil.
To get started with the E6B, try the following basic exercises: This is your Wind Correction Angle (WCA)
A pilot is flying a Cessna 172 with a True Airspeed (TAS) of knots. They are heading into a -knot headwind.
