If the wind is a headwind, your groundspeed must be lower than your TAS. If the E6B says otherwise, you've made a rotation error.
Find your Wind Correction Angle (WCA) and Groundspeed (GS). The Steps: 320∘320 raised to the composed with power under the True Index. Slide the grommet to a reference line (e.g., ) and mark a dot Rotate the wheel to align 030∘030 raised to the composed with power under the True Index. Slide the card so the wind dot sits on your TAS of The Solution: Your WCA is roughly 14∘14 raised to the composed with power Left and your GS is knots . Mission 2: The Calculator Side (Time, Speed, & Fuel)
Set the Wind Direction (180°) under the "True Index" at the top.
The front of the E6B is used for calculations involving time, speed, distance, and fuel. Use the Outer Scale (Miles/Fuel) and Inner Scale (Time) to solve the following: 1. Time, Speed, and Distance Exercise A: e6b flight computer exercises
on the outer scale. The value directly beneath it on the inner scale is your time in minutes. ~22 minutes. Exercise 2: Fuel Consumption

Many E6B computers have dedicated conversion arrows for statute/nautical miles and for gallons/liters, making these conversions quick and intuitive. If the wind is a headwind, your groundspeed
Setup: Align the Rate pointer to 115. Find 80 on the inner scale. Result: The outer scale above 80 shows . Exercise 2: Fuel Consumption
Align the 60-minute index triangle with 112 (11.2) on the outer scale. Locate 36 on the outer scale. Read the time on the inner scale directly below 36. 193 minutes (3 hours and 13 minutes). Section 3: Altitude and Airspeed Corrections
Your aircraft burns 11.5 gallons of fuel per hour (GPH). You are planning a flight that will take 2 hours and 15 minutes. How much fuel will you burn? The Steps: 320∘320 raised to the composed with
) is used to determine Wind Correction Angle (WCA) and Groundspeed (GS). 1. Heading and Groundspeed Scenario A: True Course (TC): 090 raised to the composed with power True Airspeed (TAS): 125 knots 180 raised to the composed with power at 20 knots
: Simple multiplication and division using the "60 to 1" rule. Wind Correction
Indicated Altitude 7,000 ft, Calibrated Airspeed (CAS) 120 kts, Temperature 5∘C5 raised to the composed with power C . Find True Airspeed (TAS). 5. Comprehensive Cross-Country Planning Exercise Use all skills to solve this realistic scenario: Route: KLAX to KSAN True Course: 155∘155 raised to the composed with power Distance: 90 NM Altitude: 6,500 ft Temperature: +5∘Cpositive 5 raised to the composed with power C Calibrated Airspeed (CAS): 130 kts Wind (from WX briefing): 270∘270 raised to the composed with power Calculate: Pressure Altitude (Assuming standard altimeter) True Airspeed (TAS) Wind Correction Angle (WCA) Groundspeed (GS) Total Time to Destination (EET) Total Fuel Required (Assuming 10 GPH) Answer Key for Practice
Rotate the disk to align 120 on the inner scale under the "Naut" arrow.
