  1. Navigation 3.07 E6B 1: Flight calculations References: FTGU pg 199 Online Emulator: http://www.csgnetwork.com/e6bcalc.html

  2. 3.07 Navigation – E6B E6B Class #1 • Distance Conversions • Time, Speed, Distance • Fuel calculations E6B Class #2 • Density Altitude • True airspeed, Indicated airspeed E6B Class #3 • Wind Correction • Magnetic Heading

  3. 3.07Navigation – E6B MTPs • The E6B flight computer • Calculations • Distance Conversions • Time, Speed, Distance • Fuel calculations

  4. 3.06 Navigation – E6B • “Wiz Wheel” • Used for • Quick calculations during flight • Determining the winds effect on an aircraft • All calculations may be done without a flight computer

  5. 3.07 Navigation – E6B Types of Flight computers • E6B • CR3 • Electronic

  6. 3.07 Navigation – E6B Calculations Wind Calculations E6B – It has 2 sides

  7. 3.07 Navigation – E6B Type of calculations • Conversions • Distance • Quantity • Temperature • Speed (CAS, TAS) • Weight • Calculation • Time, Speed, Distance • Fuel, GPH, Time

  8. 3.07 Navigation – E6B • Vocabulary • Inner Scale (B) (time, IAS) • Outer Scale (A) (distance, fuel, groundspeed) • Index/Rate arrow

  9. 3.07 Navigation – E6B Scale: The numbers on the flight computer range from 10 to 90. These can represent any number Ex. 12 can represent: 0.12, 1.2, 12, 120… NOTE: when doing calculations do some mental math!!!! Does the number you get make sense

  10. 3.07 Navigation – E6B Distance Conversions Conversions • Distance Manually KM to SM *.62 NM to SM *1.15 SM to NM *.87

  11. 3.07 Navigation – E6B Distance Conversions Example #1 61 sm is equal to ____NM 61*0.87 = 53 OR • Find 61 on the inner wheel • Turn 61 so it is lined up with the STAT miles on the outer scale • Read the number under NAUT miles = 53

  12. 3.07 Navigation – E6B Distance Conversions Example #2 100 nm is equal to ___ SM 100nm * 1.15 = 115sm • Find 100 on the inner wheel • Turn 100 so it is lined up with the NAUT miles on the outer scale • Read the number under STAT miles = 115

  13. 3.07 Navigation – E6B Distance Conversions KM to SM *0.62 SM to KM *1.60 NM to SM *1.15 SM to NM *0.87 Your turn: Convert the following • 75 KM = _____ SM • 40 NM = _____ SM • 90 SM = ______ NM • 25 SM = ______ KM • 120 NM = _____ SM 47 46 78 40 138

  14. 3.07 Navigation – E6B (T, V, D) calculations Time (T), Speed (V), Distance (D) calculations How long will it take to go 40 nm while travelling 75 knots? T = D/V T= 40/75 T = .53 hr = .53*60 = 32 min A. Finding Time

  15. 3.07 Navigation – E6B (T, V, D) calculations • Turn the inner dial so the RATE ARROW lines up with the speed on the outer scale (75kts) • Find the distance on the outer scale (40nm) • Read the time on the inner scale = 32 min

  16. 3.07 Navigation – E6B (T, V, D) calculations V = 120kt, D= 140nm, T = ? Turn the inner dial so the RATE ARROW lines up with the speed on the outer scale (120kts) Find the distance on the outer scale (140nm) Read the time on the inner scale = 1hr 10 min

  17. 3.07 Navigation – E6B (T, V, D) calculations B. Finding Distance • Just like how you can rearrange the triangle, you can solve all parts of the triangle on the wheel • How far will you travel in 35 minutes travelling at 75 kts? D= V*T D=75*(35/60) D=44nm

  18. 3.07 Navigation – E6B (T, V, D) calculations • Line up the rate arrow to the speed on the outer dial (75 kt) • Find the time on the inner dial (35) • Read the distance across from the time on the outer dial (44 nm)

  19. 3.07Navigation – E6B (T, V, D) calculations C. Finding speed V = D/T What is your speed if you have travelled 10nm in 8 minutes? V= 10/(8/60) = 76kts

  20. 3.07 Navigation – E6B (T, V, D) calculations • Find your time on the inner dial (8min). • Line it up with your distance on the outer dial (10nm) • Find the rate arrow and read off the speed on the outer dial (76kt)

  21. 3.07 Navigation – E6B (T, V, D) calculations Your turn: Solve the following • How far will you travel in 45 minutes at 90 mph? 2. How fast are you travelling if you cover 75 nm in 1.5hrs? • How long does it take to fly 100 nm if you are flying at 85 kts? 68 sm 50 kts 1:10 Remember: Inner dial = time, outer dial = distance, rate arrow = speed

  22. 3.07 Navigation – E6B Fuel Calculations Fuel calculations are exactly like time speed and distance calculations Time = Time Speed = Fuel consumption rate Distance = Total fuel

  23. 3.07 Navigation – E6B Fuel Calculations Your turn: Solve the following • How many gallons of fuel do you need to travel for 1.75 hours with a burn rate of 15gph? 2. What is your fuel consumption rate if you have travelled for 50 minutes and have burned 8 gallons of fuel? • How long can you fly if you are burning 12gph and have 40 gallons of fuel? 26 gal 9.6gph 3:20 Remember: Inner dial = time, outer dial = total fuel, rate arrow = fuel consumption rate

  24. 3.07 Navigation – E6B Confirmation 123sm 225min 75nm 100kt 3.5gal 253min 8.3gph 1. 107 NM = ______ SM 2.V =80 kt, D = 300nm, T= _____ 3. V =105kt, T = 43min, D= _____ 4. T= 9min, D= 15nm, V = ______ 5. V= 7gph, T= 30min, D= ______ 6. V=9gph, D=38gal, T=_______ 7. T=1:15, V=10.4, D= ______ Remember: Inner dial = time, outer dial = distance, rate arrow = speed

  25. 3.07 Navigation – E6B Confirmation There are many more calculations that the E6B flight computer can solve but these are the main ones you’ll see. 1. Distance conversions 2. Time, Speed, Distance Calculations 3. Fuel Calculations

  26. 3.07 Navigation – E6B Confirmation Homework: • Create some problems on your own to solve • Use the online emulator (listed on the first page) or do your own math todouble checkyour answers. • Be completely comfortable doing the types of problems we covered for next class • If you need more guidance watch you tube videos, there are LOTS out there • Practise: http://www.gleim.com/aviation/computerinstructions.php
