E6B Flight Computer

2. How to use the E6B Flight Computer The E6B has two primary part: the circular slide rule and the wind side The back of the flight computer with the wind side allow calculations for wind correction angle and ground speed With the E6B you can do many conversions too. These include nautical to statute miles, miles to kilometers, US gallons to Imperial Gallons, Quantity to Weight conversions. We will go over some basic calculations here.

3. E6B Time En Route Calculation First thing to do is set the rate arrow on the E6B flight computer to your desired airspeed. Lets assume your airspeed will be 180 knots. The distance between your starting point and destination is 270 nautical miles. Set the rate arrow to 180 knots. You must add a zero to the outer scale numbers. Now the rate arrow should be lined up with 18 on the outer scale. Distance is on the outer scale. You will notice small text indicating measurement(distance). ON the outer scale fine the distance of 27+0 (270NM). On the inner scale you can see that 270NM is lined up with 90. Your flight time between the two points is 90 minutes. See, not so complicated! Let's try a fuel burn and endurance calculation next.

4. E6B Fuel Endurance and Burn Calculation From the data about you know the time en route, so if your aircraft is burning 18 gallons per hour then 18 gallons x 1.5 hours = 27 gallons.What if you arrive at your destination airport and the weather is lousy or the runway is closed due to an incident? We will need to calculate the range of your aircraft in nautical miles to determine which airport you can fly to. If the fuel endurance of your aircraft is 6 hours minus the 1.5 hours you have already flown, then that leaves you with 4.5 hours. Find 4:30 on the inner scale of the E6B. Your rate arrow should still be lined up on the 180 knots ground speed. The value across from 4:30 is 81. 81 x 10 = 810 nautical miles for the distance you can fly. http://www.pilottrends.com/e6b-flight-computer
