Hi,
So always bear in mind that you descend way better at high flight levels than below 10.000feet!
So If you are high @ FL250, at a low speed, initially select your speed and put it up! Select 300kts, you will decend believe me!
Then, if you re still way too high! Use half Speed brakes!
Then if you re still WAY too high, use FULL speed brakes and disconnect the A/P because remember with the A/P ON, the speed brakes will only extend to half deflection!
If all of this is not enough... well think about other options!
-Request MORE track miles (if vectored)
-Ask to enter a hold
Bear in Mind ATC is there to help you out! If you are not comfortable with their vectors or the way they will shortcut you TELL THEM UNABLE!
I hope it helps!
Below 10.000feet, as stated in an above post, config 2, Non standard L/G down, you will "fall" like a stone!
All the best, and happy flying!
