Abstract
A system and method to display, when within an envelope of an ownship's flight path, a symbol representing wake turbulence from another aircraft based on aircraft type and flight parameters received from the other aircraft, the symbol being formatted to indicate the severity of portions of the wake turbulence. The format is modified periodically in accordance with the aircraft's flight path and a decay rate of the wake turbulence.
Claims20
A system for displaying a wake turbulence of an aircraft with respect to an ownship, the system comprising:
- a plurality of data sources configured to determine:
- a location, flight parameters, and a type of the aircraft;
- and
- a location, flight parameters, and a type of the ownship;
- a processor coupled to the plurality of data sources and configured to determine:
- an envelope relating to a flight path of the ownship;
- a wake turbulence within the envelope of the aircraft in consideration of the location, flight parameters, and the type of the aircraft;
- periodically a decay rate of the wake turbulence;
- periodically a severity of the wake turbulence with respect to the decay rate;
- and
- a format indicating the severity, the format consisting of a plurality of spaced lines formed perpendicular to the direction of flight when the wake turbulence is determined;
- and
- a display consisting of a horizontal situation indicator and coupled to the processor and configured to display in a two dimensional view the format of the wake turbulence.

A method for displaying a wake turbulence of an aircraft with respect to an ownship, comprising:
- determining a location, flight parameters, and a type of the aircraft;
- determining a location, flight parameters, and a type of the ownship;
- determining an envelope of concern relating to a flight path of the ownship;
- determining a wake turbulence within the envelope of the aircraft in consideration of the location, flight parameters, and the type of the aircraft;
- periodically determining a decay rate of the wake turbulence;
- periodically determining a severity of the wake turbulence with respect to the decay rate;
- determining a format indicating the severity, wherein determining the format comprises:
- providing a plurality of parallel lines perpendicular to the direction of flight of the aircraft, and formatting each line to indicate a severity of the line;
- and
- displaying the format of the wake turbulence in a two dimensional view on a display consisting of a horizontal situation indicator.
