Eclipse Aerospace has added an anti-skid braking system as an option for its new-production Eclipse 550s, and it plans to offer it as a retrofit for in-service Eclipse 500s early next year. Eclipse says that in-aircraft testing of the anti-skid braking system is complete and that it expects to begin delivering certified systems by late March. Performance demonstrated during testing has prompted Eclipse to seek to adjust the aircraft flight manual performance numbers for Eclipse 500s and 550s with the improved braking system.
