Thank you, Madam Chair.
I also want to thank our many witnesses for being here this morning.
My questions are for Ms. Wiebe and Mr. Wilson, but the questions can be directed at other people as needed. I want brief answers since I have many questions and only a short amount of time.
Mr. Wilson, you said in your opening remarks that you've been doing everything in your power to achieve the noise abatement objective. However, this seems a little vague to me. Is there a numerical standard?
For example, I remember reading that the ICAO says that the noise levels shouldn't exceed 55 decibels. Is there a numerical objective for noise?
