Transport committee  It depends on which stage of flight you're talking about. For departures, it is the engines. For arrival, it is the body of the aircraft. It's the air rushing over the aircraft that makes more noise than the engines on the final part of the descent.

Transport committee  There are generations of difference between them. If you could put a 707 back at Toronto Pearson and then fly in a 787 behind it, nobody would dispute the fact that they have become significantly quieter.

Transport committee  The problem is that there are vents in the underside of that wing and the wind rockets over it, a bit like blowing over the top of a bottle. It is a small piece of metal that has to be attached just ahead of that hole so as to disrupt the airflow so that you do not get that hummi

Transport committee  I don't. I've had different values quoted because different airlines have different maintenance agreements with Airbus. Some people quote $5,000 or $7,000. The cost of the piece is small compared with the cost of taking the aircraft out of service. You have to drain the fuel to b

Transport committee  No, there was no specific reason why we hadn't. It is a case of our making recommendations about extending the night and changing the controls on the night to potentially freeze the quantity of noise where it is, rather than taking a decision or a recommendation that would have a

Transport committee  Thank you.

Transport committee  Certainly in Germany, traffic is relocated from Frankfurt to Cologne and aircraft have been relocated because the aircraft doesn't just do the one flight. Overall, that has had an impact on Frankfurt's business.

Transport committee  Building a new airport and moving the whole of the business is a significant undertaking. It has been done by some cities. It is not just the airport you need to consider relocating, generally a huge amount of other infrastructure is required, and the development tends to grow to

Transport committee  History has shown that if you leave both airports open, a lot of the air carriers will not want to relocate, because relocation is a significant cost to them and their business. The first airport tends to have the best connections and the greatest value to them.

Transport committee  In the few days that I've been working in Canada, I would certainly say that Canada has come to the noise mitigation topic later than a lot. Europe and Australia have been looking at this for many more years. The U.S. also, to some extent, is ahead of Canada on this. I only have

Transport committee  Certainly, passengers could choose not to take night flights, as an example, and to travel during the day. That would be one situation such as that, yes.

Transport committee  I don't believe there's one or a small number that you should look at. Hence, when we undertook the best practices piece of work for the GTAA, we looked at 26 international airports, because it is from taking that broad view that you start to get the multiplicity of the flavours

Transport committee  Fifty-five is the standard that the European Union asks airports to report against. It is not a mandated standard that has to be achieved. It is a benchmark to measure the population affected, but it is not something that has to be achieved.

Transport committee  In general.... We looked at weekends and night flights.

Transport committee  Yes, as a basic rule.
