Aircraft takeoff trajectory is automatically optimized to minimize Perceived Noise Level. A flight computer automatically performs all the actions to takeoff the airplane and assure that its real takeoff trajectory is compliant with the takeoff trajectory optimized. Variability of trajectory is eliminated through automation of pilot's actions during takeoff and assurance of an optimum trajectory. The system also provides for simultaneity of actions and the changing of aerodynamic configuration during takeoff.

The invention relates to a method for generating at least one engine-out standard instrument departure trajectory, called EOSID trajectory, for at least one take-off runway, each EOSID trajectory being associated with a respective take-off runway.

The method is implemented by an electronic generating device and comprises, for each take-off runway, the following steps: acquiring a set of characteristic(s) relating to the take-off runway, the set of characteristic(s) comprising an orientation of the axis of the take-off runway with respect to North; calculating, from the acquired set of characteristic(s), at least one flight segment of a respective EOSID trajectory, the heading of each segment being defined with respect to the orientation of the take-off runway axis; and generating each EOSID trajectory from the calculated flight segment(s).

Disclosed herein is a conductive coating composition that includes a functionalized carbon nanomaterial and/or boron nanomaterial and a fluid component. The nanomaterial and fluid component forms hydrogen bond network in the disclosed composition. Because of the formed hydrogen bonds, the disclosed coating exhibits enhanced thermal or electrical conductivity. Also disclosed is a method to improve thermal or electrical conductivity of an existing coating composition.

An autothrottle for an aircraft that includes a power-control input (PCL) manually movable by a pilot along a travel path to effect a throttle setting that controls engine power of the aircraft. The autothrottle determines a control-target setting for a throttle of the aircraft and dynamically adjusts the throttle according to the control-target setting, including moving the PCL to achieve the control-target setting. A virtual detent is set and dynamically adjusted at positions along a travel path of the PCL corresponding to the control-target setting. The virtual detent is operative, at least when the autothrottle is in a disengaged state for autothrottle control, to indicate the control-target setting to the pilot via a haptic effect that applies a detent force opposing motion of the PCL in response to the PCL achieving the position of the virtual detent.

A method and system allowing fully autonomous automatic take-off using only images captured by cameras on the aircraft and avionics data. The system includes an image capture device on the aircraft to take a stream of images of the runway, image processing modules to estimate, on the basis of the streams of images, a preliminary current position of the aircraft on the runway and to assign a preliminary confidence index to the estimate. A data consolidation module can determine a relevant current position of the aircraft on the runway by consolidating data originating from the image processing modules with inertial data to correct the estimate of the preliminary current position and determine a relevant confidence index using a current speed of the wheels of the aircraft to refine the preliminary confidence index. A flight control computer can control and guide aircraft take-off.
