There is described a method for generating a parameter for airfoil performance monitoring, the method comprising: receiving at least a first signal indicative of a first airflow parameter measured at one of an aft position and a side-facing position of a sensor mast mounted to an airfoil and at least a second signal indicative of a second airflow parameter measured at a fore position of the sensor mast; generating a turbulence intensity ratio for each one of the first airflow parameter and the second airflow parameter; and combining the turbulence intensity ratio of the first airflow parameter and the turbulence intensity ratio of the second airflow parameter to generate a combined turbulence intensity ratio for airfoil performance monitoring.

A method and a system for providing a sighting reticle oriented to aim at a target from a vehicle within an environment of the target are described. The method improves the situational awareness of the operator regardless of the orientation and motion of the aiming instrument. The method comprises providing a graphical image representing the environment seen from the vehicle when aiming at the target; determining a state of the vehicle with respect to a spatial reference point; overlaying the sighting reticle onto the graphical image, the sighting reticle indicating the target on the graphical image with respect to the spatial reference point, the sighting reticle comprising a marking defining the spatial reference point; positioning the sighting reticle to orient the marking based on the state of the vehicle; and displaying on a display device the sighting reticle positioned on the graphical image to enable aiming at the target.

A navigation procedure display is described. The navigational procedure display includes a dynamic information area, positioned within the flight procedure display, for displaying a current procedure instruction and at least one successive procedure instruction. The navigational procedure display also includes a moving map area, positioned within the procedure display, for displaying a current position indication in at least three dimensions and situational awareness symbols.

Methods and systems for displaying procedure information

A method and apparatus is disclosed for displaying a dynamic parameter, the apparatus comprises a display unit receiving a display signal and displaying a scale that changes dynamically and non-linearly in accordance with a selected display algorithm, the display unit further displaying a pointer pointing to said scale in accordance with a reading of said dynamic parameter, thereby emphasizing a range of said reading of said dynamic parameter.

Dynamic non-linear display

A method and apparatus are disclosed for estimating a position of a target of interest using a plurality of position detection sensors wherein for at least one of the sensors, a corresponding time-variant detection probability profile is combined with the detection status received from the sensor and further wherein each of the corresponding detection probability profiles is combined to generate a global detection probability profile, wherein the combining comprises probabilistically adding a first given probability profile in the case where a first given corresponding indication comprises a target detection and probabilistically subtracting a second given probability profile in the case where a corresponding second given indication comprises a target non-detection and wherein the position of the target is estimated using the highest probability region(s) of the generated global detection probability profile.

Method, apparatus, and sensor mast for airfoil aerodynamic performance monitoring are based on pressure measurement. Pressure transducers mounted within the sensor mast measure real-time pressure, to produce an output signal. The signal is separated into steady state and overlaid ripple components. The steady state component corresponds to the mean dynamic pressure of the airflow, while overlaid ripple component corresponds to the superimposed turbulent flow component. The overlaid ripple component is transformed to an amplitude equivalent. A dimensionless ratio of the two components forms a pressure turbulence intensity factor, which may be used consistently to predict and warn of imminent stall conditions. Pressure measurement was found to be an improvement over airspeed measurement. Pressure sensors proved more robust and less fragile than airspeed sensors.
