LightPath, Native Runway Lighting for Certified Simulators

Lasa Dynamics, a Spanish manufacturing company and supplier of simulators and training services for commercial aviation pilots, introduces LightPath, proprietary software that generates native light objects within the professional simulation platform Prepar3D v5: Runway, taxiway, and approach lights modeled with real photometric parameters, including candela intensity, beam spread, color temperature and elevation profiles.

Lasa Dynamics, a Spanish manufacturing company and supplier of simulators and training services for commercial aviation pilots, introduces LightPath, proprietary software that generates native light objects within the professional simulation platform Prepar3D v5: Runway, taxiway, and approach lights modeled with real photometric parameters, including candela intensity, beam spread, color temperature and elevation profiles.

Unlike solutions based on textures or static sprites, its lights are natively integrated and become part of the system from within. "Prepar30 v5's graphics engine evaluates them in real time using Direct30 12, and their behavior responds correctly according to the pilot's position in the scene," explains Ignacio Soriano, CT0 of Lasa Dynamics.

The Real Gap in the Market

In the FSTD simulator market, there is a well-known gap between the proprietary visual systems used in high-end Full Flight Simulators and platforms such as Prepar3D, which are increasingly being used as the visual foundation for FNPT devices.

LightPath enables manufacturers building on Prepar3D to achieve the runway lighting fidelity required for FNPT-II certification under EASA CS-FSTD(A), without the need for a proprietary visual system. According to Niels Wittje, of Aeronautical Simulator Service (ass.aero), the official LightPath reseller and installation partner, "this software helps bridge the gap between high-level training simulators and entry-level certified simulators, where the visual system is not proprietary."

Relevance far Certification

LightPath is especially useful far ATOs and universities certifying simulators up to FNPT-II level equipped with Prepar3D. During qualification, evaluators review the configuration of approach lighting systems - ALSF-II, CALVERT, MALSR- the angular accuracy of PAPI/VASI systems, intensity behavior over distance and response under atmospheric conditions.

"LightPath defines every light using physical parameters, not visual approximations,"says Soriano. "Configurations are adapted to ICAO CATI, II, and III categories" -he continues- "and they are auditable and reproducible, something certification authorities value as objective evidence during the process."

Advantages and Results

These are the capabilities that make LightPath a unique product:

  • Native integration with Prepar3D, without externa! middleware.
  • Flexible configurations adaptable to customer requirements and national certification authority standards.
  • Lighting modification and redeployment without rebuilding the entire visual database, a key advantage when post-evaluation corrections must be delivered under tight deadlines.
  • Dynamic adjustment of contrast and brightness by lighting group, recreating the visual conditions required for certification.
  • An accessible commercial model tailored to the financia! reality of ATOs, universities, and FNPT manufacturers.

Despite being a relatively new product, Lasa Dynamics' LightPath has already successfully passed seven certification processes: three in Germany, one in the United Kingdom, one in Italy, and two in Spain.
