Lilium completes first systems power-on milestone for Lilium Jet

Lilium has completed the first systems power-on milestone of its all-electric Lilium Jet. The test procedure on the first in-production Lilium Jet, MSN 1, represents a significant achievement on the path to first flight and certification. This test confirms that the aircraft is being built in accordance with Lilium’s platform design and the flight systems are functioning correctly. At power-on, high-voltage is applied to the aircraft and converted to supply the low-voltage electrical and avionics systems – including cockpit display, flight controls, communication, navigation, and surveillance systems. This milestone corresponds to the customary power-on acceptance test procedure used in conventional commercial aircraft manufacturing. MSN 1 is due to become Lilium’s lab test aircraft, or “ironbird”. It will be a fully functional aircraft and key asset for the certification program, being used to prove safety of flight and compliance with airworthiness requirements. The second Lilium Jet, MSN 2, also currently in final assembly, is the first aircraft that Lilium intends to fly with a pilot on board in early 2025. Production of MSN 3 fuselage is underway at the supplier. Lilium intends to fly a total of six test aircraft up to type-certification and entry into service, targeted for 2026.
