I suggest this be made dependent on traffic density: The less traffic there is, the more likely you'll get a lift of the restriction. Ron said there is already some logic like this in v5 now.

And this is exactly what I wanted to hear, be able to be flexible.

Me too...

Testing and planned but not exactly known what rules will be followed. The r/w transport pilots are our r/w controllers were throwing it around for departure. For arrival that hasn't been brought up yet.In RC4 the manual mentions there is a pre-flight option for speed relief on departure. That I think is only available for heavies.r/w now the CDA is up for discussion with the FAA being lobbied by the airline industry. I think it was instituted for test at DFW. I just saw another r/w blurb where an airline was allowed to conduct an entire "tuned" route. Most controllers are negative about this since even with computer assistance they need to keep dynamic sight pictures of the situation in their heads. As soon as some pilot deviates for whatever reason if aircraft are scattered then it makes it difficult for a controller to notice the deviation and immediately conceive of a resolution.RC5 does/will have some randomness in routing during various phases to expedite aircraft.

I admit and agree thta CDA is somehow dangerous too - simply as planes sometime fly faster. What I seek for it that it is extremely welcome on airport such as EGLL, one of the bigggest in the world. I do not know how it is done there - perhaps at night, or at less busy hours, like in other airports where it is executed.I know that software has and will have certain limits, but since the V5 will be really great, developer could implement something that is simulatin the real thing, something that could be somehow simmilar to reality. it does not have to 100% the same, come on nothing is perfect :)

Americans have strange sense of humour that evertything outside North America or not FAA regulated is... 3rd world country.

Because of course that is exactly what I said.Goes along with your strange ability to read a post and not understand what was said in it.And your strange desire to do a CDA at 300 kts in a heavy aircraft.More power to you.

Well, reading comprehension is not your stron point either - as it is shown here. Show me point where i said anything about 300kts? I did not even mention it or anything close to it. Trurly you either have no idea about CDA or are silly. In reality 250 is a must, of course. Recomended even lower than that - usually in most cases from 200 to 220kts. in reality you can go up to 260-270-280 with ATC approval. In RC4 you can not, unless you set the tolerance limit too hight, but this is not the point either.But there is something positive from your post. I totally forgot about the tolerance level. I will simply change it and see what happens - did not test it yet.
