1. Determining True Heading
Flight
Draw line from departure airport to destination airport (Green Arrow)
Place plotter on line of longitude (yellow arrow)
Read true heading from right to left on inner scale (Red Arrow)
Flight Planning
Determining True Heading

2. Speed, Distance, and Time Computations
Speed = Distance / Time (divided by)
Distance = Speed x Time (multiplied by)
Time = Distance / Speed (divided by)

3. Time and Fuel Big Arrow divides by 60
Big Arrow on Groundspeed of 106 mph
Read time on inner scale
Distance is 60 miles 33.5 min

4. Fuel Computations Fuel Burned = Fuel consumption rate x time
Time (available) = Fuel to burn /Fuel consumption rate (divided by)
Fuel consumption rate = Fuel burned / time (divided by)

5. Fuel use Big Arrow on fuel flow (12 gallons per hour)
Read gallons used on outer scale opposite minutes (6.6gph)

Course Heading

7. Determining Wind Correction Angle
Winds 270 at 20 mph
Place wind direction under true index
Mark wind velocity up from the center.
(I used 100 and placed the wind dot on 120)

8. Figuring True Heading Place true course under true index
True Course (315)= - L (7) or + Right Wind Correction Angle = True Heading (308)

9. Ground Speed Place True Course (315)under true index
Read Ground speed under gourmet
Groundspeed is 106

10. Figuring Course Heading
Magnetic Heading (314)
Magnetic Heading Plus or minus deviation = course heading.
Deviation is a chart on the compass in the airplane we used zero as the deviation
We would fly 314 from Pickway to Grimes
