Aviation Services
GEOSAN is Mongolia's full-spectrum aviation company. We fly charter and helicopter missions, maintain aircraft under an MCAA Part 145 licence, handle aircraft on the ground, and operate airport facilities, all under one roof, since 2007.
Three Cessna Grand Caravans form the backbone of our charter network. Reliable, versatile and capable of operating from unprepared strips вЂ" our crews open field aerodromes on request to reach destinations that commercial aviation cannot serve.
GEOSAN operates two Airbus H145 twin-engine helicopters, extending our reach to terrain that no fixed-wing aircraft can access. The H145 is one of the most capable light twin helicopters in operation. Precise, safe and comfortable, it is suited to executive transport, remote-site access, search and rescue, and geophysical support.
