Overview

Arzeos Aircraft SL is a Spanish aircraft manufacturer specialising in ultralight aircraft, founded in 2019 and based in Silleda, in the Galicia region of north-west Spain. The company is a small, privately held enterprise that designs and builds its aircraft from scratch, with a stated focus on delivering what it calls an exceptional flight experience. Its factory is located at Pol. Ind. "Area 33" in Galicia, and the company invites customers and enthusiasts to visit by appointment. Arzeos's flagship and, to date, only announced product is the Arzeos Z01, an ultralight aircraft unveiled on 17 April 2024 at the Aero 2024 aviation fair in Friedrichshafen, Germany. The Z01 is a two-seat, single-engine design built around a monocoque, jointless fuselage of prepreg carbon fibre and honeycomb. It has a wingspan of 9.2 m, a length of 6.24 m, a height of 2.12 m and a cabin width of 1.22 m. Power comes from a Rotax 912 iS engine driving a three-blade constant-speed propeller, with 120-litre fuel tanks giving a claimed range of up to 2,000 km. The aircraft features a stainless-steel exhaust system developed by Arzeos, retractable landing gear with damped suspension on all wheels, and removable wings and elevator for transport and storage. Safety and avionics are central to the Z01's positioning. Active safety elements include predictable flying characteristics, an angle-of-attack gauge and a ballistic parachute; passive features include a programmed-deformation chassis and a safety-arc ceiling integrated into the fuselage. The aircraft is equipped with ALita, an automated system that monitors the aircraft and its surroundings, an AI unit, a Kanardia Nesis III EFIS and EMS, and analogue redundant instruments for airspeed, altitude, vertical speed and compass. A rear camera and USB charger are also fitted. The cockpit is designed for comfort, with independent adjustable seats, heating, panoramic visibility and noise insulation, plus a luggage compartment behind the seats. Arzeos backs the Z01 with a three-year or 300-hour warranty and free annual on-site reviews at the customer's airfield, a service it presents as proof of its commitment to pilot satisfaction. The company's team includes development, manufacturing, technical office, operations and flight-test personnel, reflecting its identity as a hands-on, engineering-led boutique manufacturer. Arzeos remains a private company and does not appear to be listed on any stock exchange.

History

Arzeos Aircraft SL was founded in 2019 in Silleda, in the Galicia region of north-west Spain. The company was established as a specialised manufacturer of ultralight aircraft, a segment of general aviation that covers light, often two-seat aircraft used for recreational and personal flying. From its base at Pol. Ind. "Area 33" in Galicia, Arzeos set out to design and build its aircraft from scratch rather than adapting an existing kit or design, an approach it highlights in its marketing. The company's first and, as of its public communications, only announced aircraft is the Arzeos Z01. Development of the Z01 was carried out in-house, with the company emphasising careful design and refined aerodynamics intended to produce smooth and dynamic flight characteristics with excellent stall behaviour. The aircraft was publicly unveiled on 17 April 2024 at the Aero 2024 aviation fair in Friedrichshafen, Germany, a major European general-aviation trade show. The launch marked Arzeos's entry onto the international stage as a new Spanish airframe manufacturer. The Z01 is built around a monocoque, jointless fuselage made from prepreg carbon fibre and honeycomb, a construction method chosen for strength and low weight. It is powered by a Rotax 912 iS engine, a widely used powerplant in the light aircraft sector, driving a three-blade constant-speed propeller. Arzeos developed its own stainless-steel exhaust system for the aircraft. The design includes retractable landing gear with damped suspension on all wheels, removable wings and elevator for transport, and a cabin 1.22 m wide with independent adjustable seats, heating, panoramic visibility and noise insulation. Safety has been a central theme of the Z01's development. Active safety elements include predictable flying characteristics, an angle-of-attack gauge and a ballistic parachute. Passive safety features include a programmed-deformation chassis and a safety-arc ceiling integrated into the fuselage. The aircraft also carries ALita, an automated system that monitors the aircraft and its surroundings, along with an AI unit, a Kanardia Nesis III EFIS and EMS, and analogue redundant instruments for airspeed, altitude, vertical speed and compass. A rear camera and USB charger round out the equipment list. Commercially, Arzeos positions itself as a customer-focused boutique manufacturer. It offers a three-year or 300-hour warranty on the Z01 and includes free annual on-site reviews at the customer's airfield, a service it presents as proof of its commitment to pilot satisfaction. The company operates a factory in Galicia that it invites customers to visit by appointment, and its team spans development engineering, manufacturing, technical office, operations support, back office and flight-test roles. Arzeos remains a privately held company and does not appear on any public stock exchange. Its public presence is centred on its official website and its appearance at Aero 2024.
