SVB, a Mountaineer

This commuter was engineered to carry fifty passengers or cargo in hot mountainous regions. It can be operated in hot climates up to 40 ° C (104° F) and out of high-altitude airfields up to 4,000 m (13,120 feet) above sea level. The SVB is powered by two TV7-117 turboprops rated at 1,840 kW (2,500 ch-e); they drive low-noise SV-34 six-blade airscrews. The cabin, which maintains a constant width from the cock­pit rear bulkhead, is pressurized and dimensioned to accommodate ten rows of five seats—separated into three and two by the aisle, 400 mm (15.75 inches) wide—at a pitch of 780 mm (30.71 inches). The cabin is 2.96 m (9 feet, 8.5 inches) wide, with headroom of 2 m (6 feet, 6.7 inch­es). The aircraft has a flight crew of two plus two cargo handlers or cabin attendants, as appropriate.

In its all-freight setup the SVB can carry a payload of 5,000 kg (11,000 pounds). At the rear of the fuselage is a loading ramp for vari­ous types of vehicles. An integral ceiling hoist helps to manipulate the freight inside the cargo hold. The aircraft is equipped with a digital
