You are cruising at 8,000 ft. The outside air temperature (OAT) is +10°C. Your Indicated Airspeed (IAS) is 140 knots.
You plan to fly a true course (TC) of 194°. Your true airspeed (TAS) is 107 knots. The winds aloft are forecast to be from 330° at 8 knots. What is your required wind correction angle and your resulting ground speed?
Steps: Align 22 minutes on the inner scale with 45 on the outer scale. Look at the 60 index (speed index). 123 knots. e6b+flight+computer+exercises+verified
The key to unlocking the E6B’s power lies in its scaling. The numbers on the scales are not always meant to be read literally; they represent multiples of 10. For example, the number "20" could mean 0.2, 2, 20, 200, or even 2,000, depending on what you're calculating. The "60" marker on the inner scale is replaced by a prominent arrow or triangle. This is your "rate index" and is central to solving problems involving time. It acts as a reference point for rates like knots, miles per hour, or gallons per hour.
The circular slide rule side of your manual E6B uses three primary scales: the outer scale (A scale/Distance), the inner scale (B scale/Time in minutes), and the innermost hour scale (C scale). The (the large triangle on the inner scale) represents 60 minutes and acts as your index for hourly rates. Verified Exercise 1.1: Calculating Groundspeed You are cruising at 8,000 ft
Locate the arrow (near 66) and the STAT arrow (near 76) on the Outer Scale. Align 45 on the Inner Scale directly under the NAUT arrow.
You are flying from Fort Worth Meacham to Denton Muni. You measure a true course of 021°. Wind is from 330° at 25 knots, true airspeed is 110 knots, and magnetic variation is 7° east. Find the magnetic heading. You plan to fly a true course (TC) of 194°
: Read the corresponding time on the inner scale: 155 minutes (2 hours and 35 minutes). Practice Problem 2: Fuel Consumption Given : Fuel Burn Rate = 8.2 GPH; Flight Time = 137 minutes.
, a student pilot whose world was defined by digital glass cockpits and iPad apps that calculated wind correction angles in a heartbeat. Elias had set a challenge: "If the electrons fail, you're flying blind—unless you can talk to the wheel." The Challenge of the Circular Slide Rule
