What feature is enhanced by the installation of setback kits on a runway?

The installation of setback kits on a runway enhances the usage of wide-bodied aircraft. Setback kits allow the runway to accommodate larger aircraft by extending the distance between the runway centerline and the edge of the safety area. This increase in space enables wide-bodied aircraft, which often have larger wingspans and different operational requirements, to operate more effectively and safely.

By providing a greater lateral distance from the runway edge, setback kits support improved maneuverability and operational efficiency for these aircraft. This is especially important in busy airports where the mix of aircraft types must be managed carefully to ensure safe takeoffs and landings. Therefore, the enhancement directly pertains to the ability of the airport infrastructure to handle larger aircraft within its design parameters.
