BRM Construções Aeronáuticas, Lda is an aircraft manufacturer whose range includes the Argos, Citius and Okavango. Its designs emphasize aerodynamic performance, stability, cabin comfort and practical flying capability, with features suited to touring and, in the Okavango’s case, short take-off and landing operations.

The Argos is built from T6 6061 aeronautical aluminum and offers a spacious cabin, ergonomic seats with four-point safety belts, gull-wing doors and a protective steel structure. It can be fitted with Rotax or Jabiru engines, and its listed specifications include a 190 km/h cruising speed with a Rotax 912 ULS engine. Citius is also built from aeronautical aluminum. Its design features 360-degree visibility, a wingtip developed to support performance at different speeds and a stated cruise-speed range of 45 to 195 km/h. Okavango is designed to combine speed and robustness with STOL capability, using a fixed leading-edge slat to support operation from less suitable strips.
