What type of aircraft incurs a weight limit at airports?

Large aircraft incur a weight limit at airports primarily due to structural capacity constraints of runways, taxiways, and apron areas. These limits are established to ensure safety and prevent damage to airport infrastructure, which can be more susceptible to the significant forces exerted by heavier aircraft. As aircraft sizes increase, the loads they place on airport surfaces also increase; thus, airports must manage their capabilities regarding maximum takeoff and landing weights.

In contrast, small regional and medium-sized aircraft typically operate at weights that are within the safety and structural limits of the average airport facility. While experimental aircraft can also face restrictions, their operations are often regulated under specific conditions due to their unique designs and testing parameters rather than standard weight limits. Therefore, large aircraft are particularly subjected to stringent weight restrictions during airport operations to maintain safety and prevent infrastructure damage.
