... 3 GA Aircraft Types Selected for Evaluation Introduction 3.1 To begin the analysis of INM modeling accuracy of GA aircraft, Task 2 developed two comprehensive lists, one of GA jets and one of propeller aircraft for initial evaluation. This section describes the method used to develop the comprehensive lists.
