Uses a clear plastic grommet and a sliding grid to calculate how wind affects your aircraft's heading and groundspeed. The Golden Rules of the E6B

A sliding grid used to determine wind correction angles (WCA), true heading (TH), and ground speed (GS) based on wind direction/velocity and true airspeed (TAS).

Your plane burns 6.2 gal/hr and has 38 gallons usable. Set the Rate Arrow to 6.2. Look at 38 on the outer scale. Verified Result: 6 hours and 8 minutes.

You are flying at a true airspeed (TAS) of 135 knots. Your aircraft burns 9.5 gallons per hour (GPH). Task: Calculate the total fuel burn for a 3-hour flight.

You traveled 45 NM in 20 minutes. What is your groundspeed? Steps:

Mastering the E6B flight computer, often called the "Whiz Wheel," requires consistent practice with time, speed, distance, fuel, and wind calculations. These verified exercises and step-by-step methods are designed to help you prepare for the FAA Private Pilot Written Test and real-world navigation. 1. Basic Calculator Side (Time, Speed, Distance) The front side of the E6B uses a 60-to-1 ratio

Slide the marked wind dot to intersect with your True Airspeed (TAS).

Set the 60 pointer on the inner scale to 140 on the outer scale. Locate 105 on the outer scale (represented as 10.5).

Slide the grid until the mark rests on the 100-knot airspeed arc. Read the groundspeed under the center grommet.

For verified practice, these tools provide automated checking:

Slide the grid so that your wind dot rests on the 120 knot TAS arc. Read the groundspeed under the center grommet (117 knots).

214 NM
