Yes, that is fair enough, because I am not sure I fully understand what an NADP is. I know that in certain other jurisdictions NADPs, specifically NADP 1, are used and this allows, for want of a better description and I am not an expert, for the throttling of aircraft at a particular rate of climb or thrust, which results in less noise being generated. I understand this is a legal requirement in some European cities. It is not being applied in Dublin. My query specifically relates to this context. If Mr. Fitzpatrick can help me out with this, I would appreciate it.
