Well Cento I feel it does come down to a A or B discussion.
If you want to get a Boeing down, slow down and put out some flap or use the speed brake.
On the Airbus the speed brake is not as effective as the Boeing's at say less than 300kts so it is often prudent to increase speed to get down to your approach commencement altitude then decelerate whilst level using drag devices A/R.
A320s with the CFM56 will fly down an ILS and maintain speed with Flap 1. An A320 with V2500s will accelerate down an ILS due to the higher idle.
Of course at some stage you will have to slow down to configure. Easier in the B than the A I feel due to higher Vfe amongst other things.
Then there is the A330.
What was this thread about again?
