Flight acoustic tests of ź└nsat╗ helicopter with greater take-off weight have been completed
The specialists ofáthe Moscow Affiliate ofáthe Central Aerohydrodynamic Institute have participated ináflight acoustic tests ofáthe multimission lightweight "└nsat" helicopter with 10%ámore take-off weight.
Acousticians have measured the local noise level and have defined more accurately the parameters ofáthe take-off flight path, level flight and the approach. Currently, the establishment ofámeasurement results toáreference conditions ofácertification are ináprogress.
Based onáthe data obtained, TsAGI specialists will develop the support documents and issue the opinion letter confirming that the helicopter noise levels meet standard requirements. This opinion letter will enable Aviaregistr toáissue the IAC certificate that proves the conformity of "Ansat" helicopter acoustic properties toáICAO and Federal Air Regulations requirements that are ináforce ináRussia. This acoustics certificate isáanáindispensable prerequisite for the helicopter toábeáauthorized for operation.
