Exterior noise certification of the Airbus A330 MRTT

Introduction

inta, spain

After Airbus modified the A330 to create the military version, they needed to update the aircraft’s noise certification so it could still use civilian airports, where noise restrictions apply.

The military version of Airbus’s A330 passenger jet needs to use civilian airports, where noise restrictions apply. After converting the A330 into the military A330 MRTT, aerodynamic changes required new measurements of noise at approach, to update the noise certification. With the support of Brüel & Kjær, Spain’s Instituto Nacional Técnica Aeroespacial (INTA) conducted the measurements and analysis required.
