Patent number: 9997078Abstract: An obstacle avoidance system is provided to assist a pilot in avoiding obstacles. The obstacle avoidance system includes a set of proximity sensors and a pilot interface device. The set of proximity sensors detects nearby obstacles by emitting a signal and receiving a reflected signal from an obstacle. A processor receives an obstacle indication from the set of proximity sensors and detects the obstacle that is in proximity to the aircraft based at least in part on the reflected signal. The processor acquires a distance and a direction to the obstacle and calculates a threat level posed by the obstacle. The pilot interface device is operable to display the following: an ownship icon indicative of the aircraft, a velocity vector icon indicative of a velocity vector of the aircraft, and an obstacle graphic indicative of the distance, direction, and threat level of the obstacle.Type: GrantFiled: September 9, 2016Date of Patent: June 12, 2018Assignee: Garmin International, Inc.Inventors: Anup A.

Patent number: 9437112Abstract: Techniques are described that allow an air traffic display of an aircraft to display the relative motion of air traffic proximate to the aircraft. The air traffic display may be switched between a first display mode in which absolute motion of air traffic is displayed (e.g., motion of air traffic targets relative to a fixed point on the earth's surface or relative to an apparently fixed celestial point is displayed) and a second display mode in which motion of air traffic targets is displayed relative to the aircraft. The techniques further facilitate the selection of individual traffic targets from a displayed traffic depiction to activate a third display mode in which additional information about the relative motion of the selected target, such as its estimated closest point of approach (CPA) to the aircraft and the estimated time it will take the selected target to reach the CPA are shown.Type: GrantFiled: June 11, 2015Date of Patent: September 6, 2016Assignee: Garmin International, Inc.Inventor: Philip A.
