Emergency calibration system

"Threepio, link Artoo Deetoo to the shipboard computer. With him augmenting its emergency calibration system-- and the pilot who brought down the death star at the controls, what do we have to worry about?"

- Leia Organa

An emergency calibration system was part of the onboard computer of Luke Skywalker's scout craft. Enhanced by an astromech droid like R2-D2, it improved a skilled pilot's ability to follow another starship closely through hyperspace.
