Life Cycle Cost of a Six Ton Helicopter

Abstract

The operating cost of a helicopter basically comprises of Direct operating cost and fixed operating cost. Direct operating cost are those costs that are related directly to the hourly operation of the helicopter. These are cost of fuel, lubricants, maintenance, overhaul, replacement of parts for the Airframe and engine. The fixed operating costs are those related directly to crew cost, insurance cost, depreciation, Hangar rentals, landing charges etc., This paper gives a method to calculate the direct and fixed operating cost for a 6 ton class civil helicopter. Realistic assumptions are made in the calculation taking into account prevailing rates wherever applicable. This cost is compared with the operating cost of various other presently flying helicopters of same category. Although operating cost of fixed wing levels can not be achieved, helicopter operators can economically compete in the short haul transportation markets where VTOL capabilities offer unique advantage. Operating cost can be reduced by Technology improvement, low cost design philosophy and progressive business policy.
