Slide the grid so the center grommet is on your actual Groundspeed (122).
Setup: Align the Rate pointer (60) to 140. Find 105 on the outer scale. Result: The inner scale below 105 shows .
Rotate the inner wheel to align the under "12" (representing 120 knots) on the outer scale. Find "18" (representing 180 NM) on the outer scale. Read the corresponding time on the inner scale. Answer: 90 minutes (or 1 hour 30 minutes). Problem B: Calculating Distance Flown Scenario: You have been flying at 95 knots for 40 minutes . Steps: Set the "60" rate arrow to "95" on the outer scale. Find "40" on the inner scale (time).

You are cruising at a groundspeed of 115 knots. How far will you travel in 45 minutes?
This utilizes the wind side of the E6B to determine your True Heading (TH) and Groundspeed (GS) given your True Course (TC), True Airspeed (TAS), Wind Direction (WD), and Wind Velocity (WV). Step-by-Step Wind Calculation Set the on the true index at the top.
Ensure you aren't confusing Statute Miles with Nautical Miles using the conversion arrows. Slide the grid so the center grommet is
Use a pencil to mark the wind velocity up from the center dot (using the concentric rings).
TAS 110 kts, TC 180°, Wind 220° at 15 kts. Find: WCA and GS.
Burn rate 11.2 GPH, Time 2 hours 15 minutes. Find Fuel Used. Result: The inner scale below 105 shows
Set the rate index arrow to 135. Find 180 on the outer scale. Look below it to find 80 on the inner scale.
How to solve: Set the Speed Index to 135. Look at 14 on the inner scale. Read the outer scale. Answer: 31.5 NM.
Rotate the inner scale until the rate index arrow points to your groundspeed on the outer scale. Look for your flight time on the inner scale.
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
