Flight Management NADP Customization for Airport-Specific Noise Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft noise abatement departure procedures (NADPs) require manual modification by pilots due to location-specific variations, leading to increased workload and difficulty in tracking and automating changes, as standard NADPs do not account for geographical and operational differences.
Innovation Solution
Aircraft systems with display devices, flight management systems, and user interfaces allow pilots to customize NADP parameters such as altitude, speed, and thrust before takeoff, enabling graphical input and automated execution by autopilot and autothrottle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard NADPs are used without modification, then the procedure follows a fixed standard format, but it cannot account for geographical location differences and operational factors
Solution Approach 1:
The system pre-loads standard NADP procedures into the flight management system database before flight operations. These standardized procedures are stored and automatically retrieved based on airport identification, eliminating the need for pilots to manually configure NADPs during pre-flight preparation.
Solution Approach 2:
The flight management system automatically identifies the departure airport and selects the appropriate standard NADP procedure from its database without requiring manual intervention. The system self-configures the vertical profile parameters based on the airport's geographical location and stored procedural data.
2Adaptability or versatility
If pilots manually modify NADP parameters for different airports, then location-specific customization is achieved, but the process becomes cumbersome and difficult to track
Solution Approach 1:
The system replaces the manual mechanical process of modifying NADP parameters with an automated electronic system. The flight management system uses computerized databases and algorithms to automatically retrieve and configure appropriate NADP procedures, substituting pilot manual input with automated electronic data processing.
Solution Approach 2:
The system creates and stores standardized copies of NADP procedures in its database for different airports and geographical locations. These pre-canned procedures are automatically copied and applied to the current flight based on the departure airport, eliminating the need for pilots to manually recreate or modify procedures.
3Adaptability or versatility
If manual NADP modification is required, then flexibility for different airports is achieved, but automation of the modified NADP becomes difficult
Solution Approach 1:
The system replaces manual NADP modification processes with automated electronic configuration. The flight management system automatically retrieves appropriate procedures from its database, configures the vertical profile parameters electronically, and loads them into the flight plan without requiring manual intervention, thereby maintaining high levels of automation.
Solution Approach 2:
The flight management system is designed with a universal database that contains standardized NADP procedures for multiple airports and geographical locations. This single system handles all NADP configurations across different airports, providing multi-functionality that eliminates the need for separate manual configuration processes for each location.
4Reliability
If standard NADP vertical profile parameters are used, then consistency is maintained, but location-specific noise certification standards cannot be met
Solution Approach 1:
The system pre-configures location-specific NADP vertical profile parameters in its database before flight operations. Each airport's specific noise abatement requirements, including altitude, speed, and thrust parameters, are predetermined and stored, allowing the system to automatically apply the correct parameters without manual configuration during flight preparation.
Solution Approach 2:
The system automatically changes NADP vertical profile parameters based on the departure airport's location-specific requirements. The flight management system retrieves and applies different altitude, speed, and thrust parameters from its database according to the specific noise certification standards of each airport, ensuring compliance without manual parameter management.

AI summary
An aircraft system comprises at least one display device within an aircraft, a flight management system (FMS), at least one user interface, and processor circuitry forming at least one processor communicatively coupled to the display device, the FMS, and the user interface. The at least one processor is arranged to operate by displaying, prior to take-off while the aircraft is on the ground, at least one noise abatement departure procedure (NADP) page, where the NADP page has at least one input field arranged to receive an NADP parameter value from a user after display of the at least one input field. The NADP page displays an indication of an NADP parameter type to be entered into the at least one input field. The processor also is arranged to operate by loading the NADP parameter value as part of a customized NADP into the FMS.
