iVL is an application for predicting aircraft performance and stability. iVL allows you to:

- Specify complex, 3-dimensional aircraft geometries.

- Create multiple, interacting lifting surfaces.

- Calculate aerodynamic forces and moments.

- Calculate aerodynamic loading on lifting surfaces.

- Automatically trim aircraft for specified flight conditions.

- Apply wing section drag modeling.

- Analyze aircraft stability.

The basis of iVL is a Vortex Lattice Method (VLM). Implementing a VLM requires simplification of the airflow around an aircraft. Despite this simplification, VLM results can be extremely useful in initial design.
