An optical system for aircraft flight control rigging, comprising: a first set of laser rangefinders configured to (i) measure, for each laser rangefinder of the first set , a distance from the laser rangefinder to a respective target location on a fixed surface of an aircraft ; a second set of laser rangefinders configured to (ii) measure, for each laser rangefinder of the second set , a distance to a respective target location on a control surface of the aircraft ; a mounting station configured to mount each laser rangefinder of the first and second sets thereto, and a processor in communication with each laser rangefinder of the first and second sets, and configured (iii) receive signals indicative of the distance measured by each laser rangefinder , (iv) generate a first plot line graphic of the measured distances of each of the laser rangefinders of the first set to its respective target location and a second plot line graphic of the measured distances of each of the laser rangefinders of the second set to its respective target location and (v) determine whether the first plot line graphic and the second plot line graphic are aligned with one another, wherein determining whether the first plot line graphic and second plot line graphic are aligned with one another comprises generating a perpendicular bisector of the first plot line graphic , and determining a distance between the first plot line graphic and a line extending through the second plot line graphic , so as to determine whether the target locations on the fixed surface and the target locations on the control surface are aligned within a predefined tolerance; and if the first and second plot line graphics are not aligned with one another, the system being configured to adjust a position of the control surface , and iteratively perform the steps (i)-(v) until the first plot line graphic and the second plot line graphic are aligned with one another. a first set of laser rangefinders configured to (i) measure, for each laser rangefinder of the first set , a distance from the laser rangefinder to a respective target location on a fixed surface of an aircraft ; a second set of laser rangefinders configured to (ii) measure, for each laser rangefinder of the second set , a distance to a respective target location on a control surface of the aircraft ; a mounting station configured to mount each laser rangefinder of the first and second sets thereto, and a processor in communication with each laser rangefinder of the first and second sets, and configured (iii) receive signals indicative of the distance measured by each laser rangefinder , (iv) generate a first plot line graphic of the measured distances of each of the laser rangefinders of the first set to its respective target location and a second plot line graphic of the measured distances of each of the laser rangefinders of the second set to its respective target location and (v) determine whether the first plot line graphic and the second plot line graphic are aligned with one another, wherein determining whether the first plot line graphic and second plot line graphic are aligned with one another comprises generating a perpendicular bisector of the first plot line graphic , and determining a distance between the first plot line graphic and a line extending through the second plot line graphic , so as to determine whether the target locations on the fixed surface and the target locations on the control surface are aligned within a predefined tolerance; and if the first and second plot line graphics are not aligned with one another, the system being configured to adjust a position of the control surface , and iteratively perform the steps (i)-(v) until the first plot line graphic and the second plot line graphic are aligned with one another. <EOS>
