摘要:
A method of high-integrity data transmission including transmitting nominally-identical data via first and second channels, inverting the logic of the data in the second channel receiving the data via a respective data handling device for each channel, inverting the logic of data outputted by one of the data-handling devices and comparing the so-inverted data with data outputted by the other data handling device. The invention is relevant to the avoidance of common-mode failures in aircraft, other vehicles and plant employing high-integrity data systems.
摘要:
An inceptor apparatus (10) for controlling a vehicle, in particular an aircraft comprises a control stick (15) for operation by a user and a user feedback generator (28) coupled to the control stick and configured to receive signals from a vehicle condition indicator (40) remote from the inceptor apparatus. The apparatus also has a first vehicle condition sensor (54,56) dedicated to the operation of the inceptor apparatus. In a first mode of operation, the user feedback generator (28) is operable to generate tactile feedback to the user via the control stick in dependence upon signals received from the vehicle condition indicator (40). In a second mode of operation, in the event that no signal is received from the vehicle condition indicator (40), the user feedback generator (28) is operable to generate tactile feedback to the user via the control stick in dependence upon signals received from the first vehicle condition sensor (54,56).
