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

Enabling Learning Objective (ELO) #1

Action: Select scales used for measurements

Condition: Given a plotter

Standard: IAW FM 1-240

Property of Lear Siegler

PLU-2/C Flight Plotter

For Sectional Charts, Use 1:500,000

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

Nautical Mile Scale - Top Scale

Labeled every 5 NM, 0 to 60 NM

Property of Lear Siegler

Nautical Mile Scale - Top Scale

Longer black increments placed every 1 NM

Shorter black increments placed every 1/2 NM

Property of Lear Siegler

Statute Mile Scale - Bottom Scale

Labeled every 5 SM, 0 to 70 SM

Property of Lear Siegler

Statute Mile Scale - Bottom Scale

Longer black increments placed every 1 SM

Shorter black increments placed every 1/2 SM

Property of Lear Siegler

Nautical Mile Scale – 1:500,000 Scale

Labeled every 5 NM, 0 to 55 NM

Nautical Mile Scale – Bottom Line

Longer black increments placed every 2 1/2 NM

Shorter black increments placed every 1/2 NM

Grommet

Used to center longitude/latitude lines

when measuring direction

Property of Lear Siegler

Direction Scales

Using longitude lines

Outer scale - use for flights in an

easterly direction, 0° to 180°

Property of Lear Siegler

Direction Scales

Using longitude lines

Inner scale - use for flights in an

westerly direction, 180° to 360°

Property of Lear Siegler

Direction Scales

Marked in 1° increments and

regardless of direction of flight

Property of Lear Siegler

60° Direction Scales

Using latitude lines

60° scale is located inside

the two larger scales

Property of Lear Siegler

60° Direction Scales

Using latitude lines

Outer scales - use for flight

in a southeast, southwest

direction, 150° - 210°

Property of Lear Siegler

60° Direction Scales

Using latitude lines

Inner scales - use for flight

in a northeast, northwest

direction, 030° - 330°

Property of Lear Siegler

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

TRUE COURSE

True course is always measured

clockwise from true north to the

proposed path of flight.

Property of Lear Siegler

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
