excellent replys...thanks guys.
but gents...when you said that all alt cstr will be respected...
let's say you are descending and there is a way point where you have to cross at or below 13000 feet and at an exact speed of 250 kts...
when you select the speed to 320 kts...is the at or below 13000 feet will be respected ?
and what about the speed (the extra) 40 kts (from 280 managed to selected 320) let's say 10 nm before that waypoint ..if i manage the speed ...do i need to use some speed brake to correct the situation...?
thanks
