Slips
dvt is a little irritating. There are two possibilities, it seems to me.
(1) dvt is confident of being right. I.e. it's all right to slip a 737-800 to lose altitude nearing a runway. In which case he just does it, and is confident of not having to explain his actions to a supervisor.
(2) dvt is not confident of being right. In which case he would be hostile and oversensitive in responding to the expressed reservations and concerns of most of the other posting members of PPRUNE.
Obviously (2) fits the data better than (1).
Now as to the merits of the quite interesting issues dvt raises.
(1) Nothing should interfere with the stabilized approach concept for largish jets. A slip (in such an airplane) is a not good idea below 1,500 feet. Surely that's a fair comment.
(2) There are slips and there are slips. Full deflection of a rudder are a really stupid idea in a swept wing jet. Light or moderate deflection with enough cross-control on ailerons, might be fine. Don't know. More to the point, neither does dvt. Is he comfortable with discussing "crossover" speed etc?
(3) If ATC gives you "crap" vectors, etc, presumably one has the ability to either dirty up or slow up. That way the "crap" vectors aren't as "crap" since the turn radius is tighter. Hence, no need for the heroics at the bottom of the approach.
(4) Many airline and jet pilots do aerobatics for fun. In an airplane designed for it. Treating a passenger jet differently (and more conservatively) is hardly effeminate.
(5) dvt needs to be counseled by his Professional Standards Committee. It's not his colleagues' job to justify their discomfort with slipping a transport jet. It's his job to justify doing it (in the absence of a compelling need to do it, or in the absence of an emergency).
(6) A Captain can do absolutely whatever needs doing in an emergency i.e. no engines, smoke in cockpit, etc. Slipping is one such thing. But when the aircraft is otherwise in fine shape, I just can't see slipping on a regular basis. That one's testosterone permits one to do it is not sufficient explanation.
