TILTROTOR IN ATM PUBLIC ACCEPTANCE AIRPORT OPERATIONS NEW REGULATIONS CONNECTED WITH THE NEW TECHNOLOGY

PUBLIC ACCEPTANCE PUBLIC ACCEPTANCE ACOUSTIC VIRTUAL NOISE (Non Acoustic)

PUBLIC ACCEPTANCE ACOUSTIC CAUSES ,[object Object],[object Object],[object Object],[object Object],SOLUTIONS ,[object Object],[object Object],[object Object],[object Object],FRIENDCOPTER

PUBLIC ACCEPTANCE VIRTUAL NOISE Is the helicopter (T/R) safe? Is it controllable? Perceived intrusion Different noise respect to the more com m on fixed wing noise Increase of the level of dB : +15/20 dB(A) SOLUTIONS ,[object Object],[object Object],[object Object],[object Object],The Community Says:

NEW RULES THE NEW TECHNOLOGIES OF THE TILTROTOR NEEDS NEW REGULATIONS ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],FAR25+29+SC
