Safety measures were implemented on specific starships to stop individuals from performing hazardous maneuvers while operating the ship. If these safety measures were active, the ship's integrated computer would simply forbid the unsafe action from occurring. These safety measures typically activated when a maneuver presented an immediate threat to the pilot's well-being or security. However, they could be deactivated if failing to perform the action would create a greater hazard.
The Whisper Bird, a Mu-class shuttle flown by Lina and Milo Graf, had safety protocols installed. When the siblings were cornered by TIE fighters, they opted for the precarious maneuver of initiating a hyperspace jump within a planet's atmosphere, a maneuver typically blocked by the safety protocols. They decided to turn them off and successfully fled.
