Regarding the noise on the 73 flight deck. I know a small trick that works on the 75 to help lower the noise maybe it works on the 73 too. It is allowed in the 75 although you really have to dig it up in the handbooks.. .. .When in cruise switch pack two off for a few minutes. Then when you restart it the packs will sort out the distribution again and the noise iss much better as less air will be directed to the flightdeck. Check with your own handbooks and don't try unless supervised by a mature adult.. .. .Any 73 drivers who can check it in their books to see whether it is allowed there too. It saves a lot of noise.... .. .Back to the topic: I understand that EZ has been checking out a 320 sim in AMS.....
