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
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

14. 3.07 Navigation – E6B (T, V, D) calculations
Time (T), Speed (V), Distance (D) calculations
How long will it take to go 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. Remember: Inner dial = time, outer dial = distance, rate arrow = speed
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. Speed = Fuel consumption rate Distance = Total fuel
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. Remember: Inner dial = time, outer dial = distance, rate arrow = speed
