Patent attributes
An aircraft having a fixed wing and a wing tip device at the tip thereof is disclosed. The wing tip device is configurable between: (i) a flight configuration for use during flight and (ii) a ground configuration for use during ground-based operations, in which ground configuration the wing tip device is moved away from the flight configuration such that the span of the aircraft wing is reduced. A locking mechanism locks the wing tip device in the flight configuration, and includes a plurality of lugs located on each of the fixed wing and wing tip device. Locking pins are inserted through and lock together corresponding lugs when the wing tip device is in the flight configuration. A secondary locking mechanism of a plurality of blocking members prevents the removal of the locking pins from the corresponding lugs, whereby the plurality of blocking members have a common actuator.
