Flaps 2 with the gear down and speed selected 190 knots, in OPEN DES, as thrust will be idle, she'll dive believe me. Tried and tested
. You can correct any deviation. Ofcourse, this does not apply to being already established on the ILS, this only applies if you've been given very short radar vectors very suddenly. As mentioned in previous posts, especially in the A320, the best dive technique when you're far out is select speed 300 or 280, disconnect the AP and use full speed brakes. Spoiler deflection with the AP disengaged is 20 deg for spoiler 2 and 40 deg for spoilers 3 & 4, unlike 12.5 deg and 25 deg respectively when the AP is engaged (A320 only). A321, the maximum spoiler deflection is 25 deg whether AP engaged or not.
When trying to catch the glide from above, best rate of descent is V/S -1500 (AT THE MOST, or anything less) else u'll go past your Vfe next and you wont be able to configure
