pyAPP6 is a Python package to interact with ALR’s Aircraft Performance Program APP.

The current implementation of pyAPP6 is a file based interface to APP. pyAPP6 classes enable to read and write APP6 files. Together with the command line interface of APP, pyAPP6 allows for automation of mission and point performance computations. The results written by APP (as text files) can be read with pyAPP6.



The Python interface allows APP to be embedded into an existing toolchain, e.g. an MDO framework. For examples of applications, please visit:
