A circuit and method for predicting an intersection of a host aircraft flight path with the wake vortex of another aircraft.

System and method for predicting and displaying wake vortex turbulence

A method and device for deriving and displaying advanced TCAS information.

Vertical speed indicator and traffic alert collision avoidance system

A method and apparatus for transmitting a directional reply signals in response to Air Traffic Control Radar Beacon System and Mode Select signals interrogation signals. Two directional antennas independently acquire an interrogation signal and are connected by means of a configurable switch to a transponder. The antennas may include multiple directional antenna elements.

Transponder having directional antennas

A method and apparatus for automatically controlling the tilt of a radar antenna to avoid ground clutter returns while scanning the weather formations of most interest. In one embodiment a terrain database is utilized to determine tilt angles for different terrain cells. The tilt angle is determined starting at the aircraft position and working out to the radar range. If a tilt angle for a more distant cell is less than for a nearer cell it is ignored taking shadowing into account. In another embodiment the weighted tilt angle frequencies are entered into a histogram and the histogram is scanned to obtain a tilt angle resulting in an acceptable amount of ground clutter.

Method and apparatus for implementing automatic tilt control of a radar antenna on an aircraft

A combined airborne Air Traffic Control Radar Beacon System/Mode-Select (ATCRBS/Mode-S) surveillance system and Traffic Alert and Collision Avoidance (TCAS) collision avoidance system device having common antennas and a switch coupling the common antennas to the relevant functions.

Multifunction aircraft transponder

A method for automatically managing the scan and tilt of an airborne radar.

Scan management and automatic tilt control for airborne radars

A hazard alert device for aircraft prioritizes various alerts according to predefined criteria. The device enables more optional alerting of hazardous conditions than a system of separate independent and discrete devices.

Integrated hazard avoidance system

Sensitivity time control (STC) data for an airborne weather radar system is provided as a function of aircraft altitude and radar system antenna tilt angle to normalize radar return signals at high as well as low aircraft altitudes. In one form of the invention the STC data is used to adjust the gain of a signal applied to a radar system received by a system antenna and in another form of the invention the STC data is used to establish a desired threshold for said signal.

Airborne weather radar system with aircraft altitude and antenna tilt

An airborne wind shear detection radar includes a transmitter for transmitting successive radar beams into airspace in front of an aircraft and a receiver for receiving reflected signals. The radar analyzes the received reflected signals in the frequency domain to determine if a wind shear condition exists in the airspace in front of the aircraft.
