The Calidus B-250 is a light attack/trainer aircraft that has been developed in Brazil but is built in the UAE by Calidus as part of the Bader program. The aircraft is intended for a range of duties, including ISR, counter-insurgency, close air support and training.
The B-250 has been designed by Novaer at São José dos Campos, near São Paulo, under the leadership of Joseph Kovács, who created the Embraer Tucano. The B-250 draws on Kovács’s work in producing the redesigned Golden Aircraft/US Aircraft Corporation A-67 Dragon, but incorporates significant elements of composite structure. It has a stepped tandem cockpit and is powered by a Pratt & Whitney Canada PT6A-68 that develops 1,600 shp. The avionics are provided by Rockwell Collins in the form of the touchscreen Pro Line Fusion system, which supports a digital head-up display.
