Descent/Approach and Landing
The speed of approach should be approximately 60 knots throughout the descent, until just before landing.
Use a steeper than normal approach-an angle of approximately 12-15º is best. This is almost the angle used for autorotation.
Do not increase the power until you are within 100 feet of the ground. Then flare and increase the power as for a normal landing.Plan the approach and landing to keep noise-sensitive areas to the left of the helicopterAvoid descending directly over noise-sensitive areas.
Cruising speed for the Agusta is 140-150 knots, which falls within the requirements of ICAO Annex 16, Chapter 8 standards for inflight noise levels. Speeds below 130 knots are noticeably quieter to people on the ground.
The A109C model is generally quieter than previous models.
