target_performance.cfg

The target_performance.cfg file is an optional aircraft file for defining performance characteristics of an aircraft. Below you can find information on the different sections used in the target_performance.cfg file as well as what parameters and values are expected within them. However it should be noted that that the information contained in this file has no influence on the aircraft flight behavior, and is instead used to compare computed performance versus expected performance (which can be found in the POH or from industrial or academic data).

 

All parameters in this file can take one or two values where:

  • The first value is the target value.
  • The second value is optional and is a Percent Over 100 providing the error tolerance when comparing this target value and the value computed in game with the flight model.

[PERFORMANCE_REPORT]

This section permits you to give an output directory to save a *.csv file too that contains all the information from this configuration file. Available parameter is:

 

Parameter Description Type Required
file_path

The full file path (and file name) to save the CSV file, eg:

file_path="C:\Users\Desktop\perf_report.csv"

String No

 

The output will look something like this:
