Patent number: 11908335Abstract: An avionic system for a rotorcraft includes a data source and an enhanced ground proximity warning system. The data source has terrain data and obstacle data stored therein. The enhanced ground proximity warning system can be selectively switched, by a pilot, to operate in either a normal mode or a desensitized mode. The enhanced ground proximity warning system receives flight data, retrieves terrain data and obstacle data from the data source, evaluates the retrieved terrain data and the obstacle data to determine variations in elevations of terrain and obstacles in predetermined area that is a predetermined distance ahead of the current position and along the flight path, and based at least in part on the determined variations, selectively generate a prompt that suggests that the pilot switch the ground proximity warning system to the desensitized mode.Type: GrantFiled: August 25, 2022Date of Patent: February 20, 2024Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Yasuo Ishihara, Margaret Wintermute, Supratik Gon

Publication number: 20240021093Abstract: A runway overrun prediction system for an aircraft includes a doppler wind measurement system and a runway overrun awareness and alerting system (ROAAS). The doppler wind measurement system is disposed at least partially within the aircraft. The doppler wind measurement system is configured to continuously measure a doppler signature of a wind field over an estimated touchdown zone on a runway ahead of the aircraft and supply wind data representative of the doppler signature. The ROAAS is disposed within the aircraft and is configured to determine a ROAAS model distance (RMD) for the aircraft. The ROAAS is in operable communication with the doppler wind measurement system and is coupled to receive the wind data therefrom. The ROAAS is further configured, upon receipt of the wind data, to adjust the RMD for the aircraft based on the wind data.Type: ApplicationFiled: August 26, 2022Publication date: January 18, 2024Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Anantha Chandrasekhar Koduru, Yasuo Ishihara, Supratik Gon, Yogesh Gharote

Patent number: 11827376Abstract: A system and method are provided for controlling operations of an enhanced ground proximity warning system (EGPWS) disposed within an aircraft that is configured to selectively operate in both a helicopter mode and a fixed-wing mode. A processor processes one or more aircraft flight parameters to determine when the aircraft is operating in the helicopter mode and when the aircraft is operating in the fixed-wing mode. The EGPWS is commanded, via the processor, to operate as a helicopter EGPWS when the aircraft is operating in the helicopter mode, and is commanded, via the processor, to operate as a fixed-wing EGPWS when the aircraft is operating in the fixed-wing mode.Type: GrantFiled: June 1, 2022Date of Patent: November 28, 2023Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Yasuo Ishihara, Supratik Gon

Patent number: 11808606Abstract: Methods and apparatus are provided for generating a runway landing alert for an aircraft. The method comprises establishing an altitude parameter and a safety envelope for a designated target runway of the aircraft. A track of the aircraft is monitored with reference to a centerline of the target runway. Any deviation by the aircraft from the centerline of the target runway is detected and determined if it is within a margin of error. If the deviation is within the margin of error, an altitude parameter is increased. If the aircraft is determined to still be maneuvering with respect to the centerline of the target runway, the altitude parameter is decreased. Otherwise, an alert is generated if the aircraft is outside of the safety envelope.Type: GrantFiled: December 13, 2022Date of Patent: November 7, 2023Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Glen Burlingame, Yasuo Ishihara, Steve Johnson, James Ehlers, Esko Mannisto

Patent number: 11472570Abstract: A system and method of shifting a premature descent protection envelope for an aircraft has been developed. First, a premature descent protection envelope (PDP) is determined including a first boundary at a first distance from the runway. Next, a nominal approach path is determined for approaching the runway and an approach path angle. Also, a flight path angle of the aircraft is determined. The first boundary is shifted in an upward direction from the runway in response to the aircraft being below the nominal approach path, and the flight path angle being greater than the nominal approach path angle.Type: GrantFiled: January 6, 2020Date of Patent: October 18, 2022Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Yasuo Ishihara, Steve Johnson, Kevin J Conner

Patent number: 11275388Abstract: Alerting systems and methods for an enhanced approach monitor are provided. The system is configured to: determine a missed approach altitude (MAA), an intended configuration, and target approach speed, each being related to the intended approach procedure and aircraft specific data. At a decision point defined as a co-occurrence of (a) the RT distance is substantially equal to or less than a distance threshold, and (b) the RT altitude is substantially equal to the MAA, the system identifies go-around scenarios, such as when (i) the RT speed exceeds the target approach speed, or (ii) the RT configuration is not equal to the intended configuration, or (iii) an RT approach path angle exceeds the target angle. The system issues a go-around alert based on whether the aircraft can perform a go-around operation, as determined based on aircraft performance data and terrain data.Type: GrantFiled: November 13, 2018Date of Patent: March 15, 2022Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Ratan Khatwa, Yasuo Ishihara
