This requires "dropping the dot" to find your Wind Correction Angle (WCA). The Setup: Set Wind Direction under the True Index Mark Wind Velocity up from the center grommet. True Course under the True Index. Slide the wind dot to your True Airspeed (TAS) Challenge: 160° at 20 knots . Your True Course is 270° (West) and your TAS is What is your Wind Correction Angle and Groundspeed? 3. Fuel Burn Calculations Fuel planning is critical for safety and completing a navigation log
9. Your aircraft burns 9.5 gallons per hour . How much fuel will you burn in 2 hours and 30 minutes ? 10. You have 35 gallons of useable fuel. If your aircraft burns 12 gallons per hour , what is your total flight time before the tanks are empty? (Assume no reserve for this calculation). 11. You have flown for 45 minutes and burned 7.5 gallons . What is your fuel burn rate in Gallons Per Hour (GPH)?
The paper is structured with an followed by a Detailed Solutions Section explaining the knob movements and slide rule operations.
