In May 2022, Jean-Baptiste Loiselet took flight aboard the Sol.Ex., an experimental solar glider that he imagined and designed himself. Since then, he has been traversing the skies, captivating attention with his exceptional flights and unprecedented performances. In August 2022, he successfully completed a Tour de France in 17 stages, entirely autonomously, without any logistical support, using only wind and sunlight. In 2023, he became the first aircraft to fly every day at the Paris Air Show without ever refueling. In 2024, he broke the world altitude record in the "electric microlight" category.

To date, the Sol.Ex. has accumulated more than 250 hours of flight time without ever being plugged into a power outlet.

We are a group of students from École Centrale de Lyon, deeply impressed by the performance of the Sol.Ex. In a context where aviation, and particularly recreational aviation, must succeed in its ecological transition, we believe that a two-seater electric motor glider, in a solar or simply electric version, could represent a significant advancement for various three-axis flight practices (gliders, planes, ultralight aircraft).

Together with Jean-Baptiste, we want to further explore this idea. Your participation in this questionnaire will help us refine our study. We sincerely thank you for your contribution!

Answering this questionnaire should take between 5 and 10 minutes. The data collected will be used solely for this study and will be anonymized in the reports.
