  5. Terminal Learning Objective At the completion of this lesson the student will: Action: Identify the characteristics of a course Condition: Given a plotter and a Sectional Aeronautical Chart Standard: In Accordance With (IAW) Field Manual (FM) 3-04.240 Property of Lear Siegler

  6. Enabling Learning Objective (ELO) #1 Action: Select scales used for measurements Condition: Given a plotter Standard: IAW FM 1-240 Property of Lear Siegler

  7. PLU-2/C Flight Plotter For Sectional Charts, Use 1:500,000

  8. SP - 4 Flight Plotter Sectional Chart Side, 1:500,000 WARNING !!! Do not use the 1:1,000,000 scale side of the plotter! Property of Lear Siegler

  9. Nautical Mile Scale - Top Scale Labeled every 5 NM, 0 to 60 NM Property of Lear Siegler

  10. Nautical Mile Scale - Top Scale Longer black increments placed every 1 NM Shorter black increments placed every 1/2 NM Property of Lear Siegler

  11. Statute Mile Scale - Bottom Scale Labeled every 5 SM, 0 to 70 SM Property of Lear Siegler

  12. Statute Mile Scale - Bottom Scale Longer black increments placed every 1 SM Shorter black increments placed every 1/2 SM Property of Lear Siegler

  13. Nautical Mile Scale – 1:500,000 Scale Labeled every 5 NM, 0 to 55 NM

  14. Nautical Mile Scale – Bottom Line Longer black increments placed every 2 1/2 NM Shorter black increments placed every 1/2 NM

  15. Grommet Used to center longitude/latitude lines when measuring direction Property of Lear Siegler

  16. Direction Scales Using longitude lines Outer scale - use for flights in an easterly direction, 0° to 180° Property of Lear Siegler

  17. Direction Scales Using longitude lines Inner scale - use for flights in an westerly direction, 180° to 360° Property of Lear Siegler

  18. Direction Scales Marked in 1° increments and read from right to left, regardless of direction of flight Property of Lear Siegler

  19. 60° Direction Scales Using latitude lines 60° scale is located inside the two larger scales Property of Lear Siegler

  20. 60° Direction Scales Using latitude lines Outer scales - use for flight in a southeast, southwest direction, 150° - 210° Property of Lear Siegler

  21. 60° Direction Scales Using latitude lines Inner scales - use for flight in a northeast, northwest direction, 030° - 330° Property of Lear Siegler

  22. Questions? Property of Lear Siegler

  23. Enabling Learning Objective (ELO) #2 Action: Measure distance Condition: Given a plotter and Sectional Aeronautical Chart Standard: IAW FM 1-240 Property of Lear Siegler

  24. DRAWING AND MEASURING COURSE LINES 1. Locate coordinate intersection. 2. Draw course line. 3. Measure the distance in nautical miles. Property of Lear Siegler

  26. Questions? Property of Lear Siegler

  27. Enabling Learning Objective (ELO) #3 Action: Plot a course in degrees Condition: Given a plotter and Sectional Aeronautical Chart Standard: IAW FM 1-240 Property of Lear Siegler

  28. TRUE COURSE True course is always measured clockwise from true north to the proposed path of flight. Property of Lear Siegler

  29. DRAWING COURSE LINES AND MEASURING TRUE COURSE 1. Locate coordinates and draw course line between the two points. 2. Estimate approximate direction before measuring. 3. Slide plotter along course line using any parallel line on the plotter until longitude line intersects grommet. 4. Use inner/outer scale and read direction in degrees. Property of Lear Siegler

  30. DIRECTION - 045° NOTICE! STRAIGHTEDGE OF THE PLOTTER MUST REMAIN PARALLEL TO COURSE LINE. NORTH? SOUTH? SOUTHEAST? NORTHEAST? MEASURING TRUE COURSE 4. Use inner/outer scale to read direction in degrees. 3. Slide plotter along course line until longitude line intersects grommet. 2. Estimate approximate direction before measuring. 1. Locate coordinates and draw course lines. Property of Lear Siegler

  31. DRAWING COURSE LINES AND MEASURING TRUE COURSE - 60° SCALE 1. Locate coordinates and draw course line between the two points. 2. Estimate approximate direction before measuring. 3. Slide plotter along course line using any parallel line on the plotter until latitude line intersects grommet. 4. Use 60° inner/outer scale and read direction in degrees. Property of Lear Siegler

  32. DIRECTION - 013° NORTH? SOUTH? SOUTHEAST? NORTHEAST? MEASURING TRUE COURSE 3. Slide plotter along course line until latitude line intersects grommet. 4. Use 60° inner/outer scale to read direction in degrees. 2. Estimate approximate direction before measuring. 1. Locate coordinates and draw course lines. Property of Lear Siegler

  33. MARKING A COURSE LINE 1. Place a tick mark every 10 NM. 2. Label tick marks every 20 NM. 3. Select a visual check point every 15 NM. Property of Lear Siegler

  34. 40 20 MARKING A COURSE LINE 2. Label tick marks every 20 NM. 1. Tick mark course line every 10 NM. 3. Select a visual checkpoint every 15 NM. Property of Lear Siegler

  35. DAY VFR CHECKPOINTS 1. Cities, towns, and airfields. 2. Highways and railroad intersections. 3. Prominent rivers and lakes. 4. Prominent terrain features. 5. Towers. 6. Prominent man-made features. Property of Lear Siegler

  36. NIGHT VFR CHECKPOINTS 1. Airport rotating beacons. 2.Cities and large towns. 3. Major, well traveled highways. 4. Prominent lakes and rivers if moonlit or near large cities. Property of Lear Siegler
