S-64 Goes Digital
Sagem Avionics of Grand Prairie, Texas, has developed a glass cockpit for the Erickson S-64 Aircrane, a type currently much in demand as an aerial firefighter. New digital avionics, together with a solid-state attitude heading reference system and three-axis automatic flight control system, complete what Sagem calls “the most extensive upgrade to the helicopter since its incorporation into the Erickson fleet.”
Two 10-inch MFDs allow the pilot to modify the displayed information depending on the type of mission. The “fire fighting” screen, for example, displays mission-specific infor- mation including the water level in the tank, the position of the water cannon and foam on and off indications. The “logging page” layout displays indications for torque, main rotor rpm and hook load on the right-hand side of the page, with additional engine and systems information on the left-hand portion.
