AD&C Flight Training 2017

It was time to refresh the flight skills of our team on a training weekend. We could achieve: Renewal of two glider and two microlight pilot licenses, four spin trainings, many hours on Tecnam P2008 and Cessna 172 and the MicroLight Comco Ikarus C42. Thanks a lot to the team of the airfield of Burg Feuerstein for the nice environment, the always friendly and motivated instructors, the flight simulator and the tasty catering.

"The possibility to work in all different subsystems of an aircraft, from wing to washer, then seeing and treating it as a whole, is what excites me most in this profession.
Being part of – and enjoying – every step in the design of an aircraft."

"This job makes the whole process of an aircraft design happen in front of my eyes. I could not ask for more.
Shaping the smart structure and optimizing it, this is what it takes to have a cutting edge design."

"To understand the physics of a technical solution and provide reliable numerical models to optimize it, this is my day to day challenge.
Follow all the steps of the creation of a part, from the first hand made sketch to its final assembly, is very exciting"

"I never get tired of looking at a product, holding it in my hands, observing it in action, after having helped shape it, having seen it develop on screen.
Fullfilling the requirements while still retaining flexibility, and allowing room for creativity."
