Designed for the missions operators actually fly.

With 800 NM range and cruise speeds up to 300 KTAS, the aircraft covers the majority of regional business aviation missions while maintaining competitive travel times. A FADEC-managed propulsion system automatically optimizes power for maximum efficiency.

Access airports closer to where business happens

With a 725 m takeoff ground roll, the aircraft can operate from a wide range of regional and constrained airports, including Cannes Mandelieu, London City and Saanen/Gstaad, bringing passengers closer to their final destination.

Refuel in all major airports today. Everywhere tomorrow.

The future of aviation infrastructure is here. Major airports already support gaseous hydrogen refueling, enabling smooth operations for early adopters. Tomorrow, with global investment in hydrogen expansion, refueling will be as effortless as Jet A-1. Whether operating a corporate fleet, fractional ownership program, or charter service, the BYA-I ensures uncompromised accessibility and operational flexibility.

One of the most spacious cabins in its class

A 1.84 m wide cabin, wider than most light jets, provides increased passenger space. With a 1.7 m cabin height and a six seat club configuration, the cabin offers a comfortable and productive environment in flight.

Carved around fuel cells & hydrogen tanks

Gaseous hydrogen tanks and system fuselage integrated with fuel cells stacks deliver energy density for efficient long-range operations compared to battery-only.

Fuel economy and faster refueling time than batteries

The BYA-I harnesses hydrogen fuel to achieve significant cost reductions and operational efficiencies compared to conventional and SAFs. By 2030, hydrogen fuel is projected to be 62% cheaper than PtL SAFs and 17% cheaper than Jet A-1, making it a more economical choice for long-term aviation.

Comparison Jet A-1 SAF biofuel SAFPtL Green H2

Cost per seat–NM €0.50 €1.40 €2.20 €0.20

Lower operating costs, simplified maintenance

Maintenance costs are expected to drop up to 60%, driven by a 90% reduction in moving parts within the propulsion system. This advantage is further amplified by the absence of a high-temperature turbine, which minimizes wear and tear, and the integration of a modular engine swap system that streamlines overhauls and reduces downtime.

As a result, the BYA-I is expected to achieve an overall operational cost reduction of approximately 40% to 60%, making it a cost-effective and technologically advanced solution for the future of aviation.

Advanced safety features

Redundancy and scalability

The powerplant incorporates built-in redundancy, enhancing safety by streamlining failure prevention and surpassing industry safety standards for backup systems. Its modular design features two electric engines, powered by independent powerplant channels, including fuel cells and multiple tanks, which allows for the expansion of power capacity to accommodate larger aircraft in the future.

Fly-by-wire technology

This system protects against errors that could exceed safe flight conditions, preventing over-speeding or manoeuvres outside of flight envelope while making the aircraft easier to operate.

Damage-tolerant structures

Designed for longevity and economic efficiency, these structures enhance safety and reduce maintenance requirements.

T-tail design

The T-tail configuration, combined with a variable incidence horizontal stabiliser, enhances stability and control during critical phases of flight, such as takeoff and landing.

Runway flexibility

Operates on grass, snow, and unpaved surfaces, expanding accessibility.
