I have a bachelor degree in Aeronautical engineering, with specialisation in the electrical area. During my former jobs I've gained a lot of experience in development phases of several systems; electrical, electronics (software), plumbing (hydraulics, air).
Within ZGE I use and extend this expertise on the systems connected to the galleys. The systems used on the galleys can be summarized by; electrical, Potable water system, waste water system, air extraction, fresh air, and bonding/grounding. All differently and with their own requirements applicable to individual or groups/families of aircraft.
