A system and method for enhanced vehicle efficiency through smart automation for an onboard weather update is provided. The system comprises a processor, and a non-transitory processor readable medium including instructions, executable by the processor, to perform a method comprising: receiving vehicle data from an onboard vehicle data source; receiving real-time weather data from one or more weather data sources; detecting when onboard forecast weather data is out-of-date or irrelevant based on the vehicle data and the real-time weather data; estimating one or more potential benefits from an update of the onboard forecast weather data; and activating the update of the onboard forecast weather data.

Enhanced vehicle efficiency through smart automation for on-board weather update

A system and method of displaying optimized aircraft energy level to a flight crew includes processing flight plan data, in a processor, to determine the optimized aircraft energy level along a descent profile of the aircraft from cruise altitude down to aircraft destination, and continuously processing aircraft data, in the processor, to continuously determine, in real-time, an actual aircraft energy level. The actual aircraft energy level of the aircraft is continuously compared, in the processor, to the optimized aircraft energy level. The processor is use to command a display device to render an image that indicates: (i) the optimized aircraft energy level, (ii) how the actual aircraft energy level differs from the optimized aircraft energy level, and (iii) how the actual aircraft energy level is trending relative to the optimized aircraft energy level.

Enhanced flight efficiency through smart automation for on-board weather update

A method and apparatus includes strategies for improving required time of arrival reliability by an aircraft comprising determining a speed correction for one of AT speed constraints or an AT or ABOVE speed constraints, wherein the determining is selected from one or more of the mechanisms from the group consisting of continuous RTA speed management between constraints, padding of the AT speed constraints and the AT or ABOVE speed constraints; decelerating proactively; and using a variable guidance margin, wherein the guidance margin is a speed change not reflected in a flight plan prediction.

System and method for managing speed constraints during required time of arrival operations

Fault-tolerant lateral waypoint sequencing is provided for a system that includes at least a first flight management computer and a second flight management computer. A processing operation associated with lateral leg sequencing of an aircraft flight plan is implemented in the flight management computers. A determination is made in the first flight management computer as to whether the first flight management computer has received, within a predetermined period of time from when the first flight management computer implemented the processing operation, a notification from the second flight management computer that the second flight has also implemented the processing operation. An action is initiated in the first flight management computer when the first flight management computer has not received the notification from the second flight management computer within the predetermined period of time.

Fault tolerant lateral waypoint sequencing system and method

A method and apparatus includes long term and short term strategies for improving 4D trajectory reliability and required time of arrival reliability. The long term strategy changes speeds along the trajectory to remove the time error in predictions. The short term strategy compensates for wind and position error, for example, by temporarily changing an aircraft guidance speed by applying a guidance margin that would either delay or prevent re-computation of the speed targets along the flight path. The predictions would use the original speed target without the guidance margin application. The guidance speed target will stay applied until the predicted time error crosses a threshold.

Aircraft control system and method for reaching a waypoint at a required time of arrival

A system is provided for controlling the speed of an aircraft during a deceleration segment between a first state associated with a first speed and a first time and a second state associated with a second speed and a second time. The system includes a navigation system configured to determine the first state; a guidance system configured to determine the second state; and an active deceleration system coupled to the navigation system and the guidance system and configured to construct the deceleration segment between the first state and the second state with at least one intermediate speed between the first speed and the second speed.

Aircraft systems and methods with active deceleration control

Methods, systems and device are provided for smoothing a required time of arrival (RTA) speed transition for an aircraft in a multi-segmented speed profile including at least one preceding region with a first predetermined speed pad and at a speed constrained region with a second predetermined speed pad. Exemplary methods include, but are not limited to determining whether a speed constrained region is engaged by a preceding region based at least in part on a speed of an aircraft. If the speed constrained region is engaged, the instructions determine a revised second speed pad for the speed constrained region. If the speed constrained region is not engaged then the instructions assign a default speed pad as the second speed pad for the speed constrained region. The instructions also compile a new speed profile that is defined by one of the revised second speed pad and the default speed pad for the speed constrained region and transmit commands that accelerate the aircraft to a new speed based on the new speed profile.

Systems and methods for RTA control of multi-segment flight plans with smooth transitions

Embodiments of a process and a program product are provided suitable for implantation by a flight management system (FMS), which is deployed onboard an aircraft and including a display device and a user interface. The FMS operable in a plurality of non-precision approach modes. In one embodiment, the process includes the steps of: (i) receiving data via the user interface designating an approach in a flight plan; (ii) enabling the pilot to utilize the user interface to select a non-precision approach mode from the plurality of non-precision approach modes if the designated approach is a non-precision approach; and (iii) placing the FMS in the selected non-precision approach mode during the designated approach.
