I'd also be interested to hear the rational behind the 1500-2000fpm instructions in the hold with aircraft 1000ft below, I seem to recall I read an ASR was submitted to this effect recently.
Are the lines of communication being improved? or is this still a matter for "discussion"
How "recently"? Whether that communication got to us at the SZC yet, I wouldn't be able to tell you.
I personally agree 2000fpm is too excessive once in the hold.
I just give "at least 1000fpm" once in the hold.
Before the hold perhaps more, if needed.
I guess just as there are pilots that don't care or understand or are unfamiliar with how it works on the other side of the mic, there are ATC that feels/think/are the same.
Personally I believe the better I understand "the cockpit", the easier it makes my job.
