E6B Flight Computer

 

E6B has 2 sides: Wind side; Computer side

Computer side has 3 outer ring Scales:

1. A Scale Distance
2. B Scale is Time (mins)
3. C Scale is Time (Hours)
4. Air Temperature/Pressure Altitude/Density Altitude

How Fast are you going?

Need 2 piece of information

1. Distance?

2. Time it took to get there?

E6B has  2 sides: Calculator side and Wind side

Question 1

1. How Long will this Flight Take if  TAS=90Knots; Winds 230@10

and from Sectional Chart you're flying:

True Course 178deg  and  True Airspeed 90Knots

Wind Side

Wind Direction under 

• Set Wind Direction 210 deg Under True Index
• Mark up 10 Knots from 100 center (set the wind volocity Mark) 
• Set/Move true course 178 under true index
• Slide the wind volocity Mark 10Knots to the True Airspeed 90Knots
• Ground Speed reads under Center which is 83Knots

How long will this Flight Take?

Calculate side

Distance 96 Nautical Miles

Set Knots 83 under Arow

A Scale Distance

B Scale is Time  

Look at 96 on upper scaler 

Read 69 mins on Scaler B

Answer = 69 knots

Question 2

Find Time, Speed, Distance, WCA, Fuel Burn
TAS = 110 Knots, Winds-330@14; Burning 15GPH
Gainsville to Ocala Distance = 182 Heading (True Course) and distance is 31 nautical miles
