Airbus advises that: At Al Ain we perform the hot weather tests, whereas in Bolivia we have performed the high altitude tests. With regards to your question on the noise, we still have to perform some tests so we are not in a position to share further data info, however we target the same performances for both the LEAP and PW which is 15dB below required noise standard. We are confident we will meet all requirements and performances as stated to our customers.
