A nacelle jet pipe is equipped with a device for regulating the pressure of a flow of air leaving the jet pipe. The system includes the digital camera and a docking unit. The button support is disposed at an outer casing of the externally operable handle and exposed through a penetration hole of the outer casing. When a user searches for a Target on their Device, the call and click data assigned to each Target is logged into a database. The rotation is then continued in order to increase the torque. Thereafter, using the self-service transaction terminal processor, a transaction is executed, based at least in part on the pre-staged transaction data.
