Pilatus PC-21 Noise Emission Testing
As part of the RAAF’s replacement of PC-9/A and CT-4B aircraft with the new Pilatus PC-21 aircraft (part of RAAF’s broader AIR5428 Pilot Training System project), noise emission data was needed for the PC-21 in order to understand the potential change in noise levels around RAAF bases where the new aircraft would operate.
This information was needed to inform an environmental study being undertaken by Defence, and provide a basis for producing an updated Australian Noise Exposure Forecast for RAAF Base East Sale (see details of MDA project here). In particular, future PC-21 operations were identified as a significant contributor to the extent of the noise contours around RAAF East Sale. Reliable input data for the modelling was therefore essential.
The type of data needed for the studies was not available from Pilatus. However, a Republic of Singapore Air Force squadron based at RAAF Base Pearce in Western Australia, operates the PC-21. This presented an opportunity to conduct noise emission testing in advance of the new aircraft being delivered for the RAAF.
