ie, if you set up the descent properly there should be no need to resort to the mistake handle. Sure, sometimes shortened routes/directs require some extra help, but there are several methods to increase ROD before you need to resort to such a crude and un-pax-friendly method. Of course there are occasions - particularly in intermediate descent at high speed with shortcuts given it may be valid.
Using speedbrake to "slow the aeroplane down"??????????? Jeez - that really is showing lack of planning!
However the use of speedbrake in conjunction with flaps on my type - 737 (a procedure frowned upon by Boeing but prevalent in my co) is the most extraordinarily cack-handed technique. A)Boeing advise us not to,so why do it it all? B) it has virtually no effect on rod below 250kts so what's the point? 3) it shakes the aeroplane and must add to pax stress and finally, 4) on finals with flap selected the next thing you're going to call for is gear, and that does affect rod - so why not call for gear early instead???? - and make sure of returning to profile?
Christ, we'll be having people sideslipping on approach next.
