Airbus has been conducting minimum-unstick testing with the A350-900 prototype at Paris Vatry airport as part of the aircraft's certification program.
The twinjet, MSN1, has "successfully completed" the test as part of the high-lift configuration optimization effort, says Airbus.
Minimum-unstick tests involve determining the lowest threshold airspeed at which the aircraft will become airborne, which requires holding the jet at a high nose attitude on rotation, to the point where the tail makes ground contact.
A380 MSN1 was on Vatry on 27/June/2007
