E6b Flight Computer Exercises Better -
Enhanced Flight Computer Exercises: e6b Takes the Lead
- Resolve wind vector relative to runway heading for takeoff/landing performance checks.
- Calculating fuel consumption and required fuel reserves
- Determining optimal cruise altitude and airspeed
- Accounting for wind and weather conditions
Exercise B: “No-Number” Estimation First
End of Report
- Don't Estimate, Interpolate: When reading the fine lines on the speed arcs, learn to estimate values between the lines (interpolating). For example, if a dot falls halfway between the 110 and 115 knots arcs, call it 112.5.
- Check for Gross Errors: Always ask, "Does this make sense?" If you have a 20-knot tailwind but your Groundspeed is lower than your True Airspeed, you made a mistake.
- Keep it Clean: Dirt can jam the slide rule movement. A clean E6B slides easier, making you faster.
- Mental Math Check: If your E6B says a 15-minute flight burns 500 gallons of fuel, you likely misread the decimal point. Mental math acts as a safety net for E6B errors.
- Exercise: Calculate the flight time and distance from Chicago (KORD) to Denver (KDEN) with a true airspeed of 200 knots and a heading of 270°.
- Solution: Using the E6B, enter the true airspeed, heading, and coordinates of the two airports to obtain the flight time: approximately 2 hours and 30 minutes, and distance: approximately 900 NM.
