摘要:
An apparatus, a method, a system and a computer program for providing users with early and accurate information relating to a status of a particular flight. Early and accurate information relating to a status of a particular flight is provided to the user. The method includes receiving user data that includes aircraft departure information, determining inbound aircraft data based on the user data, receiving constraint status information, generating update status data based on the inbound aircraft data, outbound aircraft data and constraint status information, and sending an update status message to the user.
摘要:
A blade angle feedback system for use with a propulsion system having a plurality of angularly adjustable blades, wherein each of the blades has an axis of rotation and is rotatable about the axis of rotation through a plurality of blade angles. The system includes a mechanism for indicating blade angle position of each of the sensed blades. The mechanism for indicating is movable through the plurality of blade angles with the blades, wherein the mechanism for indicating has a plurality of identities depending on and indicative of the blade angle. Mechanisms for designating a plurality of reference positions on the blades of the propulsion system and relative the mechanism for indicating are also provided. The system further includes a mechanism for sensing the passing and identity of the mechanism for indicating and the passing of the mechanism for designating, wherein the propulsion system, the mechanism for indicating, the mechanism for designating, and the mechanism for sensing have geometric relationship defined by geometric parameters. A device for determining time between the passing of the mechanism for indicating and the mechanism for designating and for determining the blade angle from the time, identity, and a plurality of the geometric parameters is also included. A method for determining blade angle is also provided.
