The Great Planes Laser Incidence Meter can be used to measure the angular align-

ment of various components of your airplane.

1. Stabilizer incidence relative to a reference point.

2. Wing incidence relative to a reference point (typically the stabilizer)

3. Wing/Stabilizer Twist: Use the meter to identify twisted areas in your wing or stabi-

lizer. Typically this is referred as "washout" or "washin."

4. Engine Thrust: Accurately measure the amount of down thrust or side thrust.

Note: The best time to check your airplane is when it is in the framed up

stage of assembly since it is much easier to make changes at this point.

1. The first step in using the Laser Incidence Meter is to calibrate the scale to a refer-

ence line on your aircraft. This reference line could be the centerline of the fuselage,

your workbench, the wing, or more commonly, the stabilizer.

2. Position the meter so the grips are attached to, or in line with, your chosen refer-

ence line.

Note: It is good practice to position the meter so the scale end is towards the

back of the aircraft for all measurements. This way when you read the meter, the

numbers physically above 0° would be read as positive (+) and below 0° would be

negative (-).
