Pilatus PC-24 jets now require a manual update for flight director calculations

The US aviation regulator is requiring all Pilatus PC-24 airplanes to update their flight manuals. This change addresses an issue where the flight director, which helps pilots navigate, gave inaccurate readings during landing approaches.

This is a small, routine safety update for a specific aircraft model. It means pilots will have corrected procedures to follow if their flight director miscalculates during a critical phase of flight. The change is about preventing a known, measurable risk from turning into an accident.
