Density altitude kills performance. These exercises force you to calibrate your thinking from indicated to true airspeed.
Scenario: You are flying HDG 315° at 110 knots TAS. You look down and see your ground track (Course Made Good) is 320°. Your groundspeed (from GPS or VOR timing) is 125 knots.
Scenario: You pass over a VOR at 14:25 Zulu. You pass the next VOR (exactly 32 NM away) at 14:49 Zulu.
Use the circular slide rule side of your E6B. Remember: The "60" index is your hour/minute reference point.
Speed/Distance Problems: 6. You have flown 85 nautical miles in 42 minutes. What is your Ground Speed in knots? 7. At a Ground Speed of 135 knots, how long will it take to fly 320 nautical miles? (Answer in hours and minutes). 8. If your Ground Speed is 95 knots, how far will you travel in 1 hour and 15 minutes?
Fuel Consumption Problems: 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)?
