Leonardo Falanga talks about Designing and Flying the P2012 Traveller VIP

Every engineer hopes, sooner or later, to experience the result of months of work outside the office. Electrical schematics become wiring harnesses, design reviews become certified systems, and countless hours spent in front of a computer eventually become an aircraft flying thousands of feet above the ground. For me, that moment came during a flight to AERO Friedrichshafen aboard the Tecnam P2012 Traveller VIP.

Having worked on the electrical integration of the aircraft, boarding that very airplane was much more than simply travelling to an airshow. It was the opportunity to experience the aircraft not as an engineer reviewing drawings, but as a passenger enjoying the final product. Walking through the cabin, every detail reminded me of the engineering work hidden beneath the elegant interior. Every switch, every light and every electrical function represented months of analysis, verification, testing and certification activities.

Among all the systems installed onboard, one feature immediately attracts attention: the electronically dimmable windows.

Unlike traditional aircraft shades, the P2012 Traveller VIP replaces mechanical blinds with an advanced electro-optical glazing system operating in a reverse mode configuration.

Engineering Insight

The VIP windows are based on a special switchable glazing technology operating in an inverted electro-optical mode. Inside each laminated panel are millions of microscopic liquid crystal droplets suspended within a transparent polymer film, positioned between two transparent conductive layers connected to dedicated control electronics.

When no electrical voltage is applied, the liquid crystal molecules remain aligned, allowing light to pass through almost freely and making the window transparent. When an alternating electrical voltage is applied, the molecular structure becomes randomly oriented, increasing light scattering within the material and producing a frosted appearance that reduces glare while maintaining natural daylight inside the cabin.This reverse-mode operation provides smooth, silent transition between states without anymoving mechanical parts.

Lighting & Ambiance

The absence of mechanical shades significantly improves both aesthetics and reliability while providing passengers with a premium cabin experience normally associated with larger business aircraft.

Rather than simply opening or closing a blind, passengers can continuously adjust the amount of incoming light to create the desired cabin atmosphere.

Every passenger has dedicated controls for ambient lighting, reading lights and electronically dimmable windows. The interface was specifically designed to remain intuitive while integrating multiple cabin functions into a single panel. Each passenger seat incorporates an individual control panel. The interface was designed around a very simple philosophy: every function should be immediately understandable without requiring instructions:

The Moon control allows the passenger to progressively adjust the desired dimming level, creating the preferred cabin ambience during cruise or evening operations.

The Sun control immediately switches the window to maximum transparency or maximum shading depending on the selected operating mode, allowing rapid adaptation to changing external lighting conditions.

Although the passenger experiences only a simple button press, the engineering behind the system is considerably more sophisticated. Dedicated electronics generate the alternating voltage required by the glazing system while ensuring compatibility with the aircraft electrical distribution system. One of the most rewarding aspects of this project was seeing how complex engineering can disappear behind a remarkably simple user experience.

Good engineering is often invisible.

Passengers enjoy comfort without ever thinking about the electronics operating behind the cabin panels. The greatest satisfaction for an engineer is not seeing a design on a computer screen, but watching it perform flawlessly at 10,000 feet.

Only a few months earlier they had existed merely as electrical diagrams, interface definitions, wiring lists and certification documents. Now they will become part of a certified aircraft transporting passengers across the world.

There is something uniquely satisfying about witnessing that transformation. For an engineer and maybe a next pilot, there are few greater rewards than flying aboard an aircraft that contains systems you personally helped design. It serves as a reminder that engineering is not only about calculations and certification reports. It is about creating technology that quietly improves the experience of every passenger while maintaining the highest standards of safety, reliability and innovation.

That flight to Friedrichshafen therefore became much more than a journey to an aviation exhibition. It became the first opportunity to experience, from the passenger’s perspective, the aircraft I had helped bring to life.
I will never forget that feeling.
