Yes and no.
The idea of slowing to 140-160 knots and putting all the flaps/gear out spooks a lot of guys, and I'm sure would surprise the hell out of most controllers. It's certainly the quickest way to head downhill, and you've got the added bonus of being fully configured when you finally reach the glideslope, but I'm not sure it'd put it in the basic airmanship category. I call basic airman ship doing slips and stalls, not abnormal procedures that have no profile attached to them, as you've so properly pointed out.
"Abnormal procedure?" No, no, no. That has a very specific meaning, as you're aware. Just because I don't have a shiny profile page in the manual for it doesn't mean it's "abnormal." The geniuses who write my manuals are far smarter than I am, but even geniuses cannot be reasonably expected to foresee every situation.
I'm not sure I'd call it abnormal; I am regularly cut loose, especially in SFO or SLC, in a high energy state in VMC and "God bless, tower 120.50." I don't think knowing how to comfortably extract the desired performance out of your airplane is
per se abnormal either. I would expect a new operator to feel more uncomfortable with this, but I still don't consider it "abnormal." When cut loose in a situation outside of the profiles and standard operating procedures pilots need to feel comfortable doing whatever is required (and safe, and comfortable for the passengers) to extract the desired performance from the aircraft. (If this means sucking the nose up and throwing every drag device you have out, so be it; as previously mentioned it is often the ONLY way that you will be stabilized by when you need to be stabilized.)
I like what a Brasilia guy told me once: "Let's be (expletive) pilots." Fly the airplane. I like my profiles, but not all situations are going to be covered in them, and it's important to be able to (1) recognize where the guidance provided by the standard operating procedures manual terminates and (2) rise to this occasion without it being a "big deal." (It's
not a big deal, as long as you recognize it and start fixing it right away. What IS a big deal is that less than 2% of unstable approaches, industry wide, result in a go-around. I don't like admitting that I goofed, but the first go-around is always free.)
SJI has "solved" the problem, as
@Derg points out, by saying "this is how you do this, in case you could not fill in the blanks on your own" during their long-term training. We haven't precisely done that, but we are exposed to it once in sim (it's left as an exercise to the pilot flying to figure out), and you see it all the time on line (including IOE). I would like to see us do high energy visual approaches as a designated part of the original training footprint, as 70% (or more) of the arrivals I do will be visual approaches, and a good quarter of those at major hubs may well wind up being "high energy."
