Petitions
It is far too early to be sending petitions to the Prime Minister.
The EASA working party have not yet finalised their deliberations but yet rumours abound - who knows the truth of them. When the committee publish for public comment then that will be the correct time to respond with copies to the local MPs and it is worth being ready for that.
I agree also with boseX that any response must be factually correct. The petitions so far, that i've seen on pprune - have not been so and to be honest are a bit wet between the ears.
Comments like; "very few actually use the rating fully but only use it to climb through some cloud, maybe, from time to time (or words to that effect)", rather support the continental view that it is not a serious rating.
I can tell you that my students are trained to proper standards and are able to fly an ILS to mminima.
