Vehicle alignment
Calculating the direction of travel:
-
‒ If both track figures have the same proceeding sign (+/+ or -/-), subtract the smaller figure from the larger figure and divide by 2.

15'- 5'= 10'
10' /2 = 5'
|
|
Deviation from direction of travel = 5'
-
‒ Add figures with different prefix (+/-) and divide by 2.

15' + 5'= 20'
20' / 2 = 10'
|
|
Deviation from direction of travel = 10'
The individual result is the actual alignment deviation from the vehicle longitudinal axis.
