Abstract: IP-based messages composed by distributed applications on-board an aircraft are routed to ground destinations through non-IP based communication interfaces that use packet data transmission. Addressable routing daemons resident in on-board computers are used to route messages from an on-board TCP/IP network to a selected communication interface. A communications management controller routes the messages to the communication interfaces by addressing the routing daemon associated with the communication interface selected to transmit the message.

Abstract: A system for enabling an operator to select a signal indicative of an air mode and a ground mode of an airplane is provided. The air mode is a state of the airplane when the airplane is in the air, and the ground mode is a state of the airplane when the airplane is on the ground. The system includes a plurality of sensors that sense parameters indicative of whether the airplane is sensed in the air or sensed on the ground. Sensed mode logic that determines whether the airplane is sensed in the air or sensed on the ground is provided, The sensed mode logic generates a signal indicative of a sensed ground mode when at leant two sensors indicate the airplane is sensed on the ground. The sensed mode logic generates a signal indicative of a sensed air mode when less than two sensors indicate the airplane is sensed on We ground. An operator interface is also provided. A simulated air mode and a simulated ground mode are selectable via the operator interface.

Abstract: A system for simulating an air mode and a ground mode of an airplane is provided. The air mode is a state of the airplane when the airplane is in the air, and the ground mode is a state of the airplane when the airplane is on the ground. The system includes means for sensing parameters indicative of whether the airplane is sensed in the air or sensed on the ground. Means for determining whether the airplane is sensed in the air or sensed on the ground is provided. The determining means is responsive to the sensing means, and the determining means outputs a signal that is indicative of a sensed air mode or a sensed ground mode. Means for interfacing with an operator is also provided. A simulated air mode and a simulated ground mode are selectable via the interface means.
