Enroute and Cruise Flyover
When crossing noise-sensitive areas, maintain airspeed of no more than 110 knots.
Where possible, maintain a minimum altitude of 1,000 feet above ground level. Plan routes to keep noise-sensitive areas on the left side of the helicopter.
Turn as sharply as possible. Coordinated turns at approximately the speed for the best rate of climb cause no appreciable change in noise. Sharper turns reduce the area exposed to noise.
The MD500N is quieter on the right side than on the left.
The MD500D/E is quieter on the right side than on the left, when equipped with a two-bladed tail rotor.
The MD500D/E is quieter on the left side than on the right, when equipped with a four-bladed tail rotor.
