Hm, I may have confused the terms.
I have always viewed "rate of climb" to be Distance/time (feet/minute). "SAS521 descend FL210, rate 2000 feet per minute or more". But I'm just a wannabe so it's probably I who have confused it.
So let's pose the question this way.
Does it make sense to belive (based on my previous post) that you can climb at a higher rate (feet/minute) at a low speed. Due to the decrease of resistance from air and since this there being more power available to propell the aircraft up rather than forward.
