Runway Surface Processing Module Format Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the ability for pilots to switch between different reporting formats of runway surface conditions, such as RwyCC and Non-RwyCC, to compute accurate required runway distances during landing or takeoff, which is crucial for safe aircraft operations.
Innovation Solution
A method and apparatus that configure a runway surface processing module to process multiple types of runway surface information, allowing pilots to select and input different reporting formats, including ATIS, RCAM, and SNOWTAM codes, to estimate braking distance and action, and map these inputs to compute the required runway distance using a set of rules and data from a ground server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pilots use a single runway surface condition reporting format, then the system is simple to operate, but the system cannot accommodate different reporting formats (RwyCC, Non-RwyCC, SNOWTAM) transmitted by ATC
Solution Approach 1:
The runway surface processing module is designed to handle multiple types of runway surface condition information (RwyCC, Non-RwyCC, and SNOWTAM formats) through a single unified interface. The system can automatically detect and process different reporting formats transmitted by ATC, converting them all into standardized runway condition codes for distance computation, thereby eliminating the need for separate processing systems for each format.
2Measurement precision
If the system processes multiple types of runway surface information, then the computation accuracy improves, but the information processing time increases
Solution Approach 1:
The system pre-configures the runway surface processing module with the capability to handle all three types of runway surface condition information (RwyCC, Non-RwyCC, and SNOWTAM formats) before actual use. By having the processing rules and conversion logic ready in advance, the system can immediately process whichever format is transmitted by ATC without requiring time-consuming format detection or manual configuration, thus maintaining both accuracy and speed.

AI summary
A method and apparatus for assessing runway surface conditions including: configuring a runway surface processing module to process: a first type of reported runway surface condition information, a second type of a set of Runway Condition Assessment Matrix (RCAM) codes, and a third type of a set of runway surface condition codes including: SNOWTAM codes; selecting, at least one of the first, second or third types of runway surface information to input to the runway surface processing module, to estimate at least a braking distance and a braking action of the aircraft; receiving, by input, one of at least the first, second or third types of runway surface information by the runway surface processing module; and mapping a runway surface condition, reported or entered of the first, second or third types of runway surface information, to a particular runway condition code to compute the required runway distance.
