You have just proven that you cannot answer it. And a bit hypocritical calling my post rambling.
Lets try and be absolutely clear; You need to take distance into account if you are planning a descent. You seem to have a problem with that.
Every time you do a verbose claculation, you prove me right.
Please, please, please go and do some homework and then come back to me and you will see the 3times rule is not for all speeds.
I have no idea what you are so upset about 527/333 fpm. I am not saying anything is wrong with any of them. They are just numbers in a calculation.
The reason I replied back before is that you DID NOT take distance into account and you still have not given a reason why. You added on your last post but hindsight is a great educator.
If you have a PPL or ATPL book on nav, please look it up.
