Rockwell Collins Compass Swing Demonstration for the AHS-85 and MCS-65 Systems
This course demonstrates some different compass swing techniques that can be used to align either the MCS-65 system or the AHS-85 system.
Checking the Compass Site
Visual Check
300 feet from other aircraft
600 feet from all large visible magnetic objects
Not close to fuel tanks, power lines, buildings, light poles, railroad tracks, or underground fuel lines or tanks
Check for underground power cables, reinforcement rods, and natural magnetic changes
Marking the Site
Find center and mark
Center tripod and level over mark
Align north mark to magnetic pointer
Mark a spot 125 feet north from center
Mark other cardinal points 125 feet from center
Checking the Site Marks
Move transit to north mark, center and relevel compass
Place rod on east point and measure angle from north
Should be 135 degrees to east mark, 180 degrees to south and 225 degreesto west
Repeat from all cardinal points
From east, north should be 315 degrees, west – 270 degrees, and south – 225 degrees
From south, east – 45 degrees, west – 315 degrees, north – 0 degrees
Alternate method – ramp squares

Compass Swing Using Voltage Method
Aircraft positioned accurately
North heading
Set sin voltage at test point 1 to 0 V, test point 2 for cosine compensation, and test point 6 for the index compensation to 0 V.
Set-up mode
Connect meter to test point 3
Record voltage 4 seconds after it comes on
Use the correct meter
Fluke 8062
Three decimal places after voltage readings
Good sampling rate
Fluke 87
Three decimal places
Analog voltage scale
Hold mode
Windspeed
Less than 15 knots
Read 8 voltages
