An aircraft includes first units each including a first sensor, a rotary wing, a driver, and a first drive controller. The first drive controller is configured to generate a drive signal of the rotary wing on the basis of a flying route of the aircraft and a control law based on a flying state detected by the first sensor, and output the drive signal to the driver configured to drive the rotary wing. The control laws of the respective first drive controllers are equal to each other between the first units. The first drive controllers are each configured to generate the drive signals that correspond to all of the first units. The drivers are each configured to drive the corresponding rotary wing on the basis of corresponding one of the drive signals that correspond to all of the first units and that are generated by the first drive controllers.

A control system for a movable body is mountable on the movable body. The control system includes controllers and a detector. The controllers are configured to control functional systems of the movable body. The detector is configured to detect a movement situation of the movable body. Priorities corresponding to movement situations of the movable body are in advance assigned to each of the plurality of functional systems. When at least one of the plurality of controllers malfunctions, control resources of normal controllers, among the plurality of controllers, which do not malfunction are preferentially distributed to one or more of the functional systems having a high priority according to the movement situation of the movable body at that time.

A failure diagnostic system includes an instrument and a failure diagnostic device. The instrument makes measurement of a measured value regarding behavior of a diagnosis target. The failure diagnostic device has a model of the diagnostic target and performs simulation based on the model. The failure diagnostic device offers a user a proposal for execution of a special operation on the diagnostic target, on the condition that a difference between a result of the simulation and the measured value is greater than a predetermined error range but the difference provides an insufficient basis to determine whether or not the diagnosis target has a failure. The result of the simulation is calculated with the model supplied with a same input as an input to the diagnosis target at the time of the measurement by the instrument of the measured value regarding the behavior of the diagnosis target.

An aircraft control system has a flight specification acquisition sensor for acquiring flight specifications of an aircraft and outputting the respective numerical values, and a plurality of flight computers, each having the same control software and performing airframe control based on the flight specification numerical values, thereby constituting a redundant system of flight control functions. Further, the control system includes a noise generator for the plurality of flight computers, which generates a plurality of noises different from each other, and the plurality of noises are individually superimposed on the numerical value of one flight specification output from the flight specification acquisition sensor to generate a plurality of new flight specification numerical values different from each other which are then output to the plurality of flight computers. This configuration ensures redundancy of the aircraft control software against potential bugs using the same control software.

An independent and interlocking redundancy system includes one or more control targets, operation processors, and one or more standby processors. The one or more standby processors is configured to make transition from a standby state to a warming-up state when one of the operation processors malfunctions, transmit, in the warming-up state and to the one or more control targets, a control command same as that transmitted to the one or more control targets by non-malfunctioning one of the operation processors, at a timing at which the malfunctioning one of the operation processors is supposed to transmit the control command, and determine and transmit the control command independently from and by taking turns with respect to the non-malfunctioning one or more of the operation processors, after warm-up of the one or more standby processors is completed.

A traffic control training scenario generation apparatus generates a training scenario for traffic control communication. The apparatus includes: a display unit and a display control unit that performs display control of the display unit. The display control unit displays on the display unit form generation buttons that respectively correspond to setting forms to set processings including voice input receiving processing and voice output processing in the training scenario, displays on the display unit one of the setting form corresponding to one of the form generation buttons when the form generation button is operated by a user, and displays on the display unit a connection line connecting between the multiple setting forms when an operation is performed by a user to cause processing in the training scenario to proceed between multiple ones of the setting forms displayed on the display unit.
