Systems power-on paves the way for Lilium Jet’s ground testing campaign
Munich, October 1, 2024 – Lilium N.V. (NASDAQ: LILM), a leader in electric aircraft manufacturing and a pioneer in Regional Air Mobility (RAM), has successfully completed the systems power-on milestone for its all-electric Lilium Jet. The first in-production aircraft, MSN 1, has undergone the crucial power-on procedure, marking a significant step towards its first flight and future certification. This milestone confirms that the aircraft is being built according to Lilium’s platform design and that its flight systems are operating correctly
The power-on process involves applying 900 volts of high voltage to the aircraft, which is then converted to supply the low-voltage electrical and avionics systems, including cockpit displays, flight controls, communication, navigation, and surveillance systems. This is a key step in aircraft manufacturing, commonly known as the power-on acceptance test, and mirrors procedures used in conventional commercial aircraft
Chief Technology Officer Stephen Vellacott, elaborated on the significance of this key step in Lilium’s path towards aircraft completion:
“Power-on is an important quality gate in the production process of any commercial aircraft. The two Lilium Jets now on our final assembly line, and those to come, will be conforming aircraft, built to the specifications of our design organization, according to documented processes and in line with established aerospace procedures. When it comes to aircraft production, process control, repeatability, traceability, and above all safety is paramount. Achieving this first power-on milestone demonstrates that we’re on track.”
MSN 1 will serve as a fully functional test aircraft, or “ironbird,” and will be used to ensure flight safety and compliance with airworthiness standards. Meanwhile, MSN 2, currently in final assembly, will be the first Lilium Jet flown with a pilot onboard, with this milestone expected in early 2025. Lilium is also progressing with the production of MSN 3’s fuselage, which is being built by its supplier. The company plans to fly six test aircraft before entering service, targeting type certification by 2026.
