Set burn to 8.5 GPH. To find fuel used in 45 minutes, look at 45 on the inner scale; the outer scale shows approximately 6.4 gallons. Conversions:
Set a timer for 2 minutes. See how many of the following 3 problems you can solve: e6b flight computer exercises better
Do 5 wind problems. If error >3° or >5 kt GS, redo – only E6B. Enhanced Flight Computer Exercises: e6b Takes the Lead
Complete the calculation—set wind, mark velocity, and slide to TAS—in under 45 seconds. Why it helps: Minutes 0-4: Solve 5 time-speed-distance problems
: Directly across from 45, the inner ring showed 24.5 minutes.
Exercise: Set a burn rate of 8.5 gallons/hour and calculate the total fuel needed for legs of 45, 90, and 120 minutes.
