The E6B (both the circular slide rule side and the wind side) is prone to user error. Misreading the scale by a factor of 10 or forgetting to align the “grommet” (center dot) with the wind direction leads to disastrous flight plans.
Flip your E6B over to the wind side for these calculations. This is crucial for determining your True Heading (TH) and Groundspeed (GS) when dealing with crosswinds and headwinds. Exercise 6: Tracking In a Crosswind True Course (TC): 090∘090 raised to the composed with power True Airspeed (TAS): 120 knots Wind Direction/Speed: From 180∘180 raised to the composed with power at 20 knots E6B Steps: Match the wind direction ( 180∘180 raised to the composed with power ) to the "True Index" at the top. Put a pencil mark 20 units up from the center grommet. Turn the compass wheel to set your True Course ( 090∘090 raised to the composed with power ) under the True Index. e6b flight computer exercises verified
An aircraft's groundspeed is 120 knots. How far will it travel in 2 hours and 30 minutes (150 minutes)? The E6B (both the circular slide rule side
Wind Correction Angle (WCA), Ground Speed (GS), and True Heading (TH). This is crucial for determining your True Heading
Look at the pencil dot to see how many degrees left or right it sits from the vertical centerline. This is your .
