Current aviation technology is capable of increasing efficiency of flight operations by optimizing the flight profile and determining the most cost-efficient speeds and altitudes. Higher flight efficiency requires a combination of the aircraft lateral/vertical trajectory with accurate weather information. Achieving optimum and efficient operations can be straight forward during preparation of the flight, but becomes challenging once in flight, where unforeseen weather or route modifications can occur.
There are various technical limitations that prevent achievement of inflight optimization. The current technology often misses accurate flight plan information (e.g., downlink messages contain limited amount of information). In addition, current flight management systems do not support real-time weather such as 3D Grid weather, and the size of wind/temperature uplink messages is limited, thus resulting in inaccuracies of the onboard weather model. Also, a lack of systems connectivity prevents effective responses to unforeseen weather changes along the route, and datalink costs resulting from onboard weather updates can be prohibitive.
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receiving real-time weather data from one or more weather data sources; detecting when onboard forecast weather data is out-of-date or irrelevant based on the vehicle data and the real-time weather data; estimating one or more potential benefits from an update of the onboard forecast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.
Features of the present invention will become apparent to those skilled in the art from the following description with reference to the drawings. Understanding that the drawings depict only typical embodiments and are not therefore to be considered limiting in scope, the invention will be described with additional specificity and detail through the use of the accompanying drawings, in which:
In the following detailed description, embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It is to be understood that other embodiments may be utilized without departing from the scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense.
A system and method of enhancing vehicle efficiency through smart automation for onboard weather updates are disclosed herein. The system and method provide functionality that allows smart and optimized combinations of real-time vehicle data, such as flight plan data, with live weather data, such as 4Dimensional Meteorological (4DM) data, 3D Grid weather (Wx) data, crowd sourced weather data, or connected weather data, in order to estimate benefits that could result from updates of the onboard forecast weather data. If beneficial, the onboard weather forecast data can then be updated, either automatically or by a user such as a vehicle crew member or ground dispatcher.
The present system and method can be implemented for various vehicles, including airborne vehicles such as various types of aircraft, such as manned aircraft, unmanned aerial vehicles (UAVs), and the like, as well as ground-based vehicles such as cars, trucks, and the like.
In one implementation, the present approach provides up-to-date weather data for enhancing inflight efficiency of aircraft by combining real-time aircraft flight plan data (e.g., lateral and vertical routes, time schedules, and onboard weather data) with live weather data, such as 4DM data, 3D Grid Wx data, crowd sourced weather data, or connected weather data, in order to detect when onboard forecast weather is either out-of-date or irrelevant. The benefits that could result from updates of the onboard weather data are then estimated, which can be in terms of fuel saving and/or time accuracy, for example. For dispatchers, this information can be provided for all aircrafts under his/her responsibility, with dedicated cues to display the benefits, and highlights when medium/high benefits can be achieved.
The user is then allowed to update onboard weather data through automatic or manual generation and uplink of relevant information, such as predicted wind information (PWI) messages, predicted wind modification (PWM) messages, or the like. Alternatively, the user can update onboard weather data through automatic or manual generation and upload of relevant weather data to an electronic flight bag (EFB) application, enabling compressed/reduced data size. The EFB application can then use the up-to-date weather data to: generate PWI/PWM messages, or the like; allow the pilot to view these data (and eventually modify the data); and if allowed by the onboard technology, send the PWI/PWM messages to a flight management system (FMS). Otherwise, manual pilot entry of the updated data is needed.
The present method can also be implemented to automatically perform the update of the onboard weather data whenever benefits are higher than a user-defined threshold. In addition, the method also allows for restricting the weather update to specific flight segments where most of the benefits are evaluated.
Logic used to implement the present method can be located in a FMS, EFB, ground server, the cloud, or the like.
The present approach provides various benefits, including: enhanced inflight efficiency of an aircraft, through determination of real-time cost efficient speeds and altitudes, as well as calculation of a cost-efficient descent profile for the aircraft; improved on-time performance as accuracy of the forecast weather allows accurate and reliable time predictions; reductions in crew and dispatcher workloads; reduced datalink costs through optimization of weather data exchanges, as only required and useful data will be uplinked; and flight rerouting capabilities.
The present method can also be implemented to provide up-to-date weather data to onboard systems hosting an optimum speed/altitude engine (e.g., EFB, FMS, or the like). Having accurate weather data in the FMS, for example, can provide additional benefits by ensuring accurate fuel predictions (hence crew confidence) and accurate time predictions.
Further details of the present system and method are described hereafter with reference to the drawings.
Initially, method 200 refreshes predictions and weather (block 210) based on a flight plan and predictions, sent from an onboard vehicle data source such as a FMS or EFB (either cyclically or through a push manually) (block 212), and live weather data such as 3D grid weather data (block 214). The method 200 then performs optimization (OPT) profile research (block 216) to determine whether onboard forecast data is out-of-date or irrelevant. A benefit detection is then performed (block 218) to estimate the potential benefits of updating the onboard forecast weather data, based on one or more applied thresholds (e.g., airline, custom, variable) (block 220).
A determination is then made whether to apply customization manually or automatically (block 222). If manual customization is applied, then the benefit is visualized (block 224) such as on a user display, and the user is allowed to validate the benefit (block 226). If automatic customization is applied, then benefit validation take places without any user input (block 228). A determination is made whether the benefit is valid, either manually or automatically (block 230). If the benefit is not valid, method 200 comes to an end (block 232). If the benefit is determined to be valid, weather and optimization updates are selected (block 234), and sent to the onboard FMS or EFB. An onboard display then shows a benefits and optimization proposal (block 236), which can then be automatically or manually activated (block 238).
The user (crew or dispatcher) is allowed to update the onboard weather data. For example, the user can generate and upload weather data associated to each individual flight segment (climb/cruise/descent) (blocks 442). The user can also generate and upload weather data along the complete flight plan (block 444). The user can additionally update the optimum speeds/altitudes (block 446).
In one example embodiment, color determination can be employed as part of the display for the user. For example, a GREEN message color can indicate a low savings cost compared to the transaction cost; an AMBER message color can indicate a medium savings cost; a WHITE message color can indicate information is already updated; and a RED message color can indicate that the user should update the data because of high benefits.
The present method also provides for smart selection of relevant weather data surrounding a real-time flight plan (vertical and lateral trajectories) to produce an accurate weather model. For climb and descent flight segments, the method selects altitudes based on relevant weather points (e.g., wind direction change, wind magnitude change, tropopause altitude, etc.) to allow accurate 2D modelization of actual weather. For cruise flight segments, the method selects altitudes and waypoints based on relevant weather points such as wind points, and optimizes updates with respect to planned steps. Elapsed time to reach the weather points is also considered.
An example of the determination of relevant wind points for a climb segment is shown in the graph of
