摘要： A method and system for monitoring a level of liquid fuel in a tank having a known capacity, wherein the tank fluidly communicates with a fuel supply line through which the fuel is delivered in gaseous form. The method comprises measuring a flow rate of gaseous fuel flowing through the supply line, calculating an expended fuel volume based on the measured flow rate, and determining a remaining liquid fuel level in the tank based on the expended fuel volume and tank capacity. A delivery of liquid fuel to the tank is prompted in response to the remaining liquid fuel level.

摘要： A collective detent system is incorporated in combination with the flight control system of a helicopter to enhance vertical takeoff flight operations of the helicopter. One embodiment of the collective detent system includes a collective control stick that is pivotable through a range of operating positions from a full-down collective position to a full-up collective position with one of the operating positions of the range defining a vertical takeoff operating position that provides the vertical takeoff power level required for the vertical takeoff flight profile of the helicopter, a trim switch for a conventional collective trim system that is operative to implement a trim mode function wherein the collective control stick can be trimmed in any selected operating position, a vertical takeoff (VTO) detent switch that is operative to generate a detent signal when activated, an adjustable sensor that is operative to generate a stick-position signal when the collective control stick is pivoted into the vertical takeoff operating position, a restraint force generating (RFG) device, and a modified trim system circuit that functionally interconnects the trim switch, the VTO detent switch, the adjustable sensor, and the RFG device in interactive combination. Prior to pivoting the collective control stick into the vertical takeoff operating position, the VTO detent switch is activated to generate the detent signal. During the vertical takeoff profile, the adjustable sensor detects the pivotal movement of the collective control stick into the vertical takeoff operating positions and generates the stick-position detent signal in response thereto. The RFG device is automatically operative in response to the detent signal and the stick-position signal to generate a restraint force against the collective control stick to electro-mechanically "detain" the collective control stick in the vertical takeoff operating position and to impede manual movement of the collective control stick out of the vertical takeoff operating position.

摘要： In a FLIR/laser based targeting and imaging system, the ability to recognize, detect, locate, and/or track targets in an area of interest is significantly improved by reducing the fixed and dynamic alignment errors between the IR LOS and the laser LOS. Fixed alignment errors are reduced with an improved internal boresight module and corresponding boresight method. Dynamic alignment errors are reduced with an opto-electric subsystem that employs a single pitch bearing and a common pitch/yaw afocal for both the laser energy and the IR energy. A segmented window in the system housing includes a circular EMI grid pattern which significantly reduces the amount of off-axis EMI entering the optical pathways, and improved signal processing techniques are employed to enhance the quality of the IR image after the image has been digitized.

摘要： A system and method for conducting one engine inoperative (OEI) flight procedures training in a dual-engine helicopter includes a multi-function OEI training switch that is operative to initiate OEI flight procedures training by selecting one of said engines as the single operative engine for OEI flight procedures training, and a training function module that is: (1) operative to establish suppressed 30-second, 2-minute, and maximum continuous OEI operating limits for selected engine operating parameters to limit the actual power provided by said powerplant system during OEI flight procedures training; and (2) operative to generate biasing factors to control the operation of the parametric indicators for the selected engine operating parameters during OEI flight procedures training. During OEI flight procedures training, the training function module limits the actual power output of the helicopter powerplant system to the suppressed 30-second, 2-minute, or maximum continuous OEI operating limits, as selected by the pilot, while simultaneously utilizing the biasing factors to cause the parametric indicators of the selected operative engine to provide display indications to the pilot that the selected operative engine is operating at the actual 30-second, 2-minute, or maximum continuous OEI operating limits, as applicable.
