Patent attributes
An avionics wake turbulence awareness system and method for use in an aircraft includes an ADS-B receiver that is adapted to be positioned in an equipped aircraft and receives ADS-B transmissions from other aircraft. A control system is responsive to the ADS-B receiver and determines an identity for each of the other aircraft and determines a movement of each of the other aircraft relative to the equipped aircraft. The control system determines a flight path history of each of the other aircraft from their respective identities and movements relative to the equipped aircraft. An output device is responsive to the control system to provide guidance to a pilot of the equipped aircraft to avoid an encounter with a wake turbulence caution area that is defined by a flight path history of another aircraft. The control system evaluates the relative risk of the equipped aircraft encountering the respective wake turbulence caution areas of each of the other aircraft, and after selecting an aircraft of the other aircraft with a highest priority, provides guidance to the pilot of the equipped aircraft to avoid an encounter with a wake turbulence caution area of the selected aircraft.
