  3. Introduction • The E6-B flight computer is used for many flight-related calculations and conversions. • The flight computer will be used extensively during pilot training, and is very useful for flight planning and in-flight calculations.

  4. Outline • Time, Distance, & Speed • Unit Conversions • Groundspeed & Heading

  5. E6-B Flight Computer • The E6-B flight computer is used for many flight-related calculations and conversions

  6. Time, Distance, Speed • Set marker to speed (example: 80 knots/mph/etc) • Read distance on outer scale • Read time on inner scale

  7. Time, Distance, Speed • Set at 80 knots: • Dist of 40 NM = • Time of 30 min

  8. Time, Distance, Speed • Set at 80 knots: • Dist of 160 NM = • Time of 120 min • Time of 2 hrs(hour scale useful over 60 minutes)

  9. Unit Conversions • Nautical miles to/from statute miles: • Line up NAUT arrow with STATUTE arrow • Read knots/NM on outside • Read MPH/SM on inside • Example: • 61 NM = • 70 SM

  10. Unit Conversions • Statute miles to/from kilometers: • Line up STAT arrow with KM arrow • Read MPH/SMon outside • Read km/h/km inside • Example: • 56 SM = • 90 km

  11. Groundspeed & Heading • When determining your required heading (corrected for wind) and resulting groundspeed for a cross-country flight, use the following procedure on the back of the flight computer: • Rotate circle so the wind direction is under “True Index” • Use a pencil to make small dot straight up from centre hole, using vertical scale to measure airspeed (in knots) • Rotate circle so the true track is under “True Index” • Slide back-plate so that pencil dot is on horizontal line that matches true air speed (TAS) • Read wind correction angle on vertical line under the pencil dot (left of centre = -, right of centre = +) • Read groundspeed under centre hole

  12. Groundspeed & Heading • Example Problem:Track = 040º trueVariation = 12º eastDeviation = 4º westTAS = 115 knotsWind = 160º true at 25 knotsWhat is the resultant ground speed and compass heading to maintain track?

  13. Groundspeed & Heading • Wind Direction: • Set 160º undertrue index • Wind Speed: • Mark dot 25 knots up from centre 25

  14. Groundspeed & Heading • True Track: • Set 40º under true index • True Air Speed: • Slide wind mark to 115 knots line 115

  15. Groundspeed & Heading • Wind Correction: • Read wind correction angleof +11º • Ground Speed: • Read resulting ground speed of126 knots 11

  16. Groundspeed & Heading • True Heading: • Add wind correction (+11º) to track (40º) • = 51º true heading • Compass Heading • Convert true heading to compass heading using variation (12º E) and deviation (4º W): TVMDC • 51º + (-12º) + 4º = 43º • Final Answer: • Groundspeed = 126 knots • Compass Heading = 043º
