摘要： An actuating system for pivoting a wing tip section (13) about a fixed wing base section (11), and including a heating arrangement (33) positioned and adapted to be operable to heat at least one portion of an actuating arrangement (23) that pivots the wing tip section such that at least for ambient temperatures below a predetermined temperature the required work to be effected by the actuator (25) when moving the second coupling part (31) between the first position and the second position is lower than without heating the at least one portion.

摘要： A system for moving an aircraft door from an open position towards a closed position. The system includes an aircraft door actuator, an input receiving primary power from a primary power supply to power movement of the aircraft door from the open position towards the closed position, a secondary power supply to power the aircraft door actuator to move the aircraft door from the open position towards the closed position, and a controller configured to cause the secondary power supply to power the aircraft door actuator to cause the aircraft door actuator to move the aircraft door from the open position towards the closed position, on the basis of a determination that insufficient primary power is available from the primary power supply via the input to move the aircraft door from the open position towards the closed position.
