RA, Crew and scientists on board: Crew (pilots + operators): VFR 1 pilot, IFR 2 pilots; Seats available for scientists: 19 (pax configuration) Cabin: Length: 6.30m Width: 1.34 m Height: 1.55 m Apertures: Main door : Width : 1.92 m Height : 1.55 m; Cabin pressurized: None. This allows very large openings in the structure. Aircraft modifications: Nose boom: none Windows: A bubble window with operator location and navigation telescope at the right front-side of the cabin. Openings: 2 openings in the cabin floor which can be opened and closed during flight : - 2060 x 515 mm (spant 19A to 23) - 475 mm diameter (spant 22 to 23) Coverable openings in the cabin roof : 400 mm diameter between fuselage-station 22 and 23 ; 150 mm diameter each between station 12A and 13B (2x) and 21 and 22 (1x). Hard points: 6 hardpoints in the middle of the fuselage floor for external loads up to 200 kg. It is planned to install a radom for the protection of sensors. Each fuselage side provides 3 hardpoint pairs below the cockpit area for a load of max. 50 kg (e.g. SLAR). Below both wings, not within the area of the propeller, there are hardpoints for 100 kg each. Inlets: 4 in total. Additionnal systems: Additional mounting rails for measuring equipment in the cabin. Tubes in the wing and the fuselage for measuring and supply lines. Breathing oxygen system for a max. of 5 persons for flights lasting up to 5 hours in a flight altitude of up to 25000 ft. Acquisition systems: Onboard data recording system. Telemetrie-link to a ground station on development.
