@ latetonite: sorry, I am not requesting descent until i need to descend!
Aircraft separation as you mention is the ATC's prerogative, until they do not give me a mini ROD to follow, I take my own...
@HighLow
Where did you get those min ROD from? ICAO? you should maybe read those text, there is no such minimum existing, and except FAA, Australia and UK (last 1500ft)...
Trusting you? right, give the reference of text your naming...
In the other states, you are allowed to use 100ftm till the ATC ask you another rate for their separation.
So if you would like to remind about the legal requirement, you should at least know them...
