-## Standard Module Design
-- Calculations not in `aircraft.cpp` (aircraft is pure data object)
-- `myTool.cpp` for calculations, has (smart) pointers to Aircraft and Settings objects
-- Do not edit standard files like aircraft.cpp, functions.cpp etc. ->use own files (myToolFunctions, myToolspecificAicraftData,...)
-
-### Structure main()
-1. Create Settings object 
-2. Create aircraft object
-3. Create myTool-object,  if necessary call init() 
-4. Call myTool.run()
-5. Create output and call writeOutput()
-6. Done

-!!! warning
-    :fontawesome-solid-arrow-right: The module structure changed in newer releases of **UNICADO**. See [Module Structure]().

 ### Inline Functions
 - Define inline functions only if they are small (~ 10 lines or less).

 ### Function Parameter Ordering
 - The sequence of parameters of a function is: first input parameters, then output parameters.
 - Input parameters are passed either as value or const reference.

 - Always use Smart Pointers instead of normal pointers (raw pointers), since Smart Pointers free up storage space at a suitable location.
 - Do not use `auto_ptr` (obsolete and not container-compatible) but `unique_ptr`.
 - Use `shared_ptr` only if several pointers to the same object are needed, because more memory is used for the reference counting.
