The Desaer ATL-100 (ATL being Portuguese for "light transport aircraft") is a twin-turboprop, high-wing, utility aircraft under development by Desaer in Brazil.[1]

Development

Desaer, a Brazilian aviation firm,[2] launched the ATL 100 project in October 2018. It was registered in Brazil as a Strategic Defense Product. In 2020, Desaer announced a joint venture with CEIIA in Portugal to manufacture the turboprop.[3] By 25 September 2020, a joint-venture between Brazilian Desaer and Portuguese engineering centre CEiiA was expected to create 1,200 jobs at a new integrated factory in Evora. The ATL-100 was to be developed over three years.[4] The partnership with CEIIA was dissolved in 2021, with a clause forbidding CEIIA from launching a similar product until 2025.[3]

By 2022, Desaer planned to start flying its ATL-100 prototype in 2023.[5] In 2022, Desaer tapped MagniX to provide engines for its ATL-100H aircraft, a planned hybrid-electric version of its ATL-100 aircraft.[5]

In early 2025, the ATL 100 was still under development, with an expected range of 1,600 km powered by two Pratt & Whitney PT-6 engines.[3] In February 2025, Desaer accused EA Aircraft and Maintenance of appropriating technical information from the ATL 100 model for its LUS 222 aircraft.[3]

Design

The ATL-100 is a non-pressurized, twin-turboprop, high-wing utility aircraft with a fixed tricycle landing gear and an aft cargo ramp. With an MTOW up to 19,000 lb (8.6 t), it should be certified under the part 23 commuter category for 19 passengers or three LD3 containers. It could operate on unpaved and short runways, with little or no ground support; it targets robustness and easy maintenance, and low operations costs. Quick-change variants could be offered for air ambulance, emergency evacuation, paratrooper or troop transport; and for patrol, surveillance, intelligence, reconnaissance.[6]

ATL-100H

The ATL-100H is a variant of the original that adds two outboard magniX magni350 electric motors to the configuration. Their role is to provide additional thrust, primarily for take-off and climbing. Each 111.5-kg (246-lb) motor offers 350-kW/1,610 Nm (1,188 ft lb) of maximum continuous torque. The company claimed that it would reduce fuel consumption by 25-40% and reduce take-off noise levels.[7]
