An aircraft includes a fuselage, a main wing coupled with and extending outward from the fuselage, and a collision avoidance system coupled with the fuselage adjacent the main wing. The collision avoidance system includes first and second laser rangefinders and a detection circuit. The first and second laser rangefinders are configured to generate laser beams laterally outward of the fuselage and include diverging lenses spreading the laser beams in a vertical dimension. The detection circuit is coupled with the first laser rangefinder and the second laser rangefinder to: detect an object within a collision risk zone adjacent to the main wing based on input from at least one of the first laser rangefinder and the second laser rangefinder; and generate an alert that the object is at risk of colliding with the main wing.
