2005 Europe/US International Aviation Safety Conference, Cologne 7-9 June 29 PUBLIC ACCEPTANCE ACOUSTIC VIRTUAL NOISE (Non Acoustic)

2005 Europe/US International Aviation Safety Conference, Cologne 7-9 June 30 PUBLIC ACCEPTANCE ACOUSTIC CAUSES  Rotors noise  Fountain effect (T/R)  Main rotor wake/tail rotor interaction (H/C)  Blade vortex interactions (BVI) SOLUTIONS  Tiltable Wing (T/R)  Present studies on the reduction of BVI  Active blade controls (flaps, HHC, IBC…)  Flying at heights greater than today (3000 ft above cities; 5000 ft above rural areas)

2005 Europe/US International Aviation Safety Conference, Cologne 7-9 June 31 PUBLIC ACCEPTANCE VIRTUAL NOISE Is the helicopter (T/R) safe? Is it controllable? Perceived intrusion Different noise respect to the more common fixed wing noise Increase of the level of dB: +15/20 dB(A) SOLUTIONS  Publicity Campaigns (Industries, Operators, Associations…)  Better public relations: understand the concerns & needs of each other  Heliports in noisy area  Re-routing, increase of flyover heights, operational procedures The Community Says:

2005 Europe/US International Aviation Safety Conference, Cologne 7-9 June 34 AIRPORT OPERATIONS  Objective: Remove IFR R/C & T/R from runway traffic by using their specific, non dependent, procedures Advantages:  for the pilot: shortened approaches (time / fuel savings)  for the controller: removes “slow traffic” from RWY approach (easier A/C-R/C-T/R separation)  for airport neighbours: less noise thanks to higher approach routes and steep final leg  for airport authorities: adds movements without contribution to RWY congestion (passenger throughput)

2005 Europe/US International Aviation Safety Conference, Cologne 7-9 June 37 OPEN QUESTIONS 1.Which are the actions that Industries, Operators, Associations, Regulations Agencies should give themselves in order to reach the goal of the introduction of the VTOL aircraft in the ATM? 2.In the case of an SNI approach, what should be the minimum separation with the other traffic? 3.What is the required navigational performance of the SNI approach procedure and how sensitive is this procedure to items as weather, system failures…? 4.What are the requirements in terms of visually acquiring, observing and guiding rotary-wing traffic to separate them from other IFR fixed-wing traffic by the control tower? 5.Does the traffic controller need special equipment, algorithms, etc. in order to reduce the mental stress or the conflict-solving predictive capability? 6.What about the new regulations connected with the new technology (Nacelle Tilting Mech., Conversion, HQ, …) ? 7.…
