The service is intended to provide customers with performance analysis software for use in various operations such as flight release, performance optimization, and flight route planning. The software is divided into three modules: the APN Performance Monitoring Module, the NEC Noise Analysis Module, and the Standard Performance Analysis Module. The APN Performance Monitoring Module is a tool within the software designed to monitor aircraft engine performance and degradation, enabling adjustments to fuel policies or the development of corresponding procedures. The NEC Noise Analysis Module also functions as a performance monitoring tool within the software, focusing on engine performance and degradation, which similarly helps in adjusting fuel policies or creating procedures. The Standard Performance Analysis Module is designed to assist with flight release, performance optimization, and route planning, including functions such as takeoff and landing analysis, flight path analysis, in-flight performance analysis, and fixed fuel flight planning. This service includes providing customers with the performance analysis software installation program and registration code. The goal of the service is to help customers use the software for aircraft performance analysis, thereby improving their ability to analyze aircraft performance.
