Lightning tests: When lightning strikes the LCA, four metal longerons stretching from end to end, afford protection. In addition, all the panels are provided with copper mesh. One out of five is 'bonding' bolt with gaskets to handle Electromagnetic interference. Aluminum foils cover bolt heads while the fuel tank is taken care of with isolation and grounding.

Highly adapted wing design with carefully blended wing-body and area ruled fuselage form the basis for unbeatable performance of LCA. Built-in aerodynamic instability imporves ability and maneuverability.  Wind tunnel tests on scale models and Computational Fluid Dynamic (CFD)analyses have successfully been used to design and freeze the complex aerodynamic configuration of the LCA, and further to generate comprehensive aerodynamic data for Control Law design, flight simulation, performance prediction and structural design.

Creating a Numerical Master Geometry (NMG) of the complete aircraft and CAD modeling of every component of the LCA, served the needs of computational analyses including CFD and Finite Element Analysis of the Airframe and other structural components.  DigitalPrototype Assembly (DPA) and Virtual Prototype of LCA built using CAD models of the components and

Lca-Tejas simulators : since there is no current twin seater  version of lca , test pilots go through training in the flight simulator like in the pictures
