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.

Time, Distance, Speed
• Set marker to speed (example: 80 knots/mph/etc)
• Read distance on outer scale
• Read time on inner scale
![Page 7: Sep 2012 Lesson 7.2 Power Pilot Flight Computer. Reference From the Ground Up Chapter 7.5: Navigation Problems Pages 197 - 207](https://reader036.vdocuments.net/reader036/viewer/2022062805/5697bfa71a28abf838c99079/html5/thumbnails/7.jpg)
Time, Distance, Speed
• Set at 80 knots:– Dist of 40 NM =– Time of 30 min
![Page 8: Sep 2012 Lesson 7.2 Power Pilot Flight Computer. Reference From the Ground Up Chapter 7.5: Navigation Problems Pages 197 - 207](https://reader036.vdocuments.net/reader036/viewer/2022062805/5697bfa71a28abf838c99079/html5/thumbnails/8.jpg)
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)

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

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

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

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

Groundspeed & Heading
1. Wind Direction:– Set 160º under
true index
2. Wind Speed:– Mark dot 25 knots
up from centre
25

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

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

Groundspeed & Heading
7. True Heading:– Add wind correction (+11º) to track (40º)– = 51º true heading
8. 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
