摘要： A device for monitoring the status of a munition fuze is disclosed. The device includes a visible marker; an indicator strip, capable of actuation, from a first state to a second state; and a power source providing power to the munition initiation system, the visible marker and/or the indicator strip. The visible marker and indicator strip are positioned to be visible to an observer when the fuze has been fitted for use on said munition and activation of the power source causes switching of the visible marker from an off state to an on state and actuation of the indicator strip from a first state to a second state, such that the power source's activation is indicated by the actuation of the indicator strip to its second state. The visible marker remains in an on state only if there is sufficient power to operate the initiation system.

摘要： There is provided a method and apparatus for simulating a flight scenario during a live flight of an aircraft. The method comprises:
(i) generating (60) images comprising scenes relevant to the simulated flight scenario at a simulated altitude;
(ii) calculating, using live flight data received for the aircraft and with reference to a predetermined flight model (65), simulated flight data for the simulated flight scenario at the simulated altitude; and
(iii) displaying, on a display system (35) of the aircraft, the calculated simulated flight data while controlling the display of said generated scene images to simulate movement of the aircraft through the displayed scene at a rate and in a direction corresponding to the displayed simulated flight data.
The method and apparatus may optionally alter the response of the aircraft to control actions (70) by a pilot to simulate the response expected of the aircraft having the simulated flight characteristics.

摘要： A method and system for positioning a vehicle in relation to each moving target of an ordered set of moving targets. Each of the moving targets moves from an initial position at a constant velocity. Embodiments can compute an estimated time for the vehicle to be positioned within a predetermined proximity of one of the moving targets; compute an estimated location of the moving target at the estimated time, based on a current position of the moving target and the constant velocity of the moving target, and compute a required velocity for the vehicle to move from its current position to reach the estimated location by the estimated time. If the required velocity is less than or equal to a maximum velocity of the vehicle, outputting the estimated time and the estimated location for use in positioning the vehicle.
