    Abstract: 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.

    Abstract: In some examples, a ground obstacle detection system of an aircraft is configured to generate and display a graphical user interface (GUI) that includes a graphical representation of a detected obstacle with which the aircraft may collide during a ground operation and an indication of an area of unknown associated with the detected obstacle. Instead of, in addition to, a GUI that includes an indication of an area of unknown associated with an obstacle, in some examples, a ground obstacle detection system to generate a GUI that includes at least two windows that present different views of an aircraft. At least one of the windows may include a graphical representation of an obstacle that may not be visible in the view of another window.

    Abstract: An enhanced flight control system and method providing a technological improvement over a conventional flight control systems is provided. A control module employs rules to determine whether or not a received traffic collision avoidance system (TCAS) evasive maneuver is automatically implemented. Specifically, the control module effectively couples the TCAS to the FMS, allowing access to the flight plan and to the navigation database and the approach procedures and runway data therein. An algorithm in the control module determines when there is a co-occurrence of the conditions (1) a flight plan uploaded in the FMS, (2) autopilot is engaged, (3) VNAV is engaged. Upon co-occurrence of (1) and (2) and (3), and an evasive maneuver is received from a TCAS, the control module determines whether or not to automatically implement the evasive maneuver. Look ahead algorithms may also analyse and modify the flight plan to preclude TCAS alerts and evasive procedures being required.

    Abstract: Disclosed is an autopilot-coupled traffic alert and collision avoidance systems (AP TCAS). The AP TCAS includes a an AP/automatic flight control system (AFCS) that is configured to receive a vertical speed setting after the issuance of a preventive resolution advisory, wherein the aircraft vertical speed setting exceeds the maximum vertical speed allowed by the resolution advisory, the AP/AFCS being further configured to: (1) modify the aircraft vertical speed setting so as to be less than the maximum vertical speed, and relay the modified second aircraft vertical speed to an autopilot system of the aircraft to automatically cause the aircraft to fly at a vertical speed in accordance with the modified second vertical speed setting; and (2) relay a command to the autopilot system to initiate an automatic, corrective flight maneuver if a current vertical speed of the aircraft is within a predetermined amount of the maximum vertical speed.

    Abstract: Systems and methods for presenting a qualitative risk assessment for an aircraft to perform a flight procedure. Methods include determining: a pilot support value that is representative of a human-machine interface (HMI) onboard the aircraft; a crew factors value representative of a number of pilots and respective experience; an equipment state value of the aircraft, representing available and functioning avionic systems; a type of procedure for the flight procedure; a remaining trip length; an airport facilities state value; an Airport facilities state value; a physical environment value; and, an environmental state value. The method calculates the qualitative risk assessment, as a function of the determined values/factors and presents the qualitative risk assessment in a predefined area on an avionic display in the aircraft.

    Abstract: Aircraft display systems and methods. Flight data is received from a Flight Management System (FMS) or other flight data source. A map display is generated based on the flight data including a depiction of a flight path and a plurality of waypoints or other fixes. A user selection of one of the waypoints or other fixes is received. An edit dialog box is generated. A value for a constraint or condition for the selected one of the waypoints or fixes is entered in the edit dialog box display by the user via a user interface device. The value for the constraint or condition is applied to the selected one of the waypoints or fixes via the FMS or other flight data source. The map display is generated including the depiction of the flight path and the plurality of waypoints or fixes. An icon is tagged to the selected one of the waypoints or fixes. The icon denotes an existence of the constraint or condition and a type of the constraint or condition. A constraint or condition dialog box is generated providing further information on the constraint or condition, in response to the user selecting the icon using the user interface device.

    Abstract: Methods and system for alerting descent with respect to at least one of minimum sector altitude, minimum safe altitude and terrain clearance floor in an aircraft. The methods and systems receive at least one of a minimum sector altitude value, a minimum safe altitude value and a terrain clearance floor value based on a flight plan of the aircraft or a location of the aircraft. A movement trajectory of the aircraft is predicted. The aircraft predicted movement trajectory is evaluated with respect to the at least one of the minimum sector altitude value, the minimum safe altitude value and the terrain clearance floor value. An alert is output when the evaluation predicts convergence of the aircraft predicted movement trajectory and the at least one of the minimum sector altitude value, the minimum safe altitude value and the terrain clearance floor value.
