Dan Gryder has done some testing suggesting otherwise.
Which leads me to believe my fellow PoAers that much more.
Or are you making a joke about how he crashed into a cornfield a couple years ago?
I firmly believe that the myth that "go arounds are free," kills pilots. And leads to ****ty landing skills. I had an instructor who taught me that if there's something wrong with your approach, you fix it, and you land where you intended to land. Go arounds were a last resort and to be avoided.
Of course it's better to do it right every time. But the broader point is being able to do it every time. I have seen some CFIs who teach their students to "go around early and often," which I consider really bad training. Turning based too early, over/undershooting final by a bit, adding flaps too late/early, etc. are to be avoided, but they are not reasons to go around.
All approaches require a million little fixes. The key is to make them before the accumulate into a big one at the end.
Y'know... There are some arguments we've had at PoA over the years where there are very good points in both directions, and this looks like it could turn into one of those, but has led me to what I think I will do (and if I ever get around to getting my CFI, teach).
Of course if you go around for every stupid little thing, that will hurt you when you don't have the option to go around (after engine failure). You need to learn how to fix a bad approach.
On the other hand, a lot of GA pilots will get into an accident after trying to force an approach that is bad. So we can't just say "going around leads to ****ty landing skills" as those students will be the ones who end up in landing accidents in normal operations.
If we had to choose one of the two, I'd rather have my students have better skills in normal operations than emergency operations, given the relative incidence of each. However, I think there's a middle ground.
It's kind of like the "Pitch for airspeed, power for altitude" during a landing approach vs. the more intuitive "power for airspeed, pitch for altitude". There have been plenty of arguments as to how it should be taught, but I really like what I saw here on PoA once: Power controls how much total energy you have, pitch controls how you split it between airspeed and altitude.
In the professional flying world, stabilized approaches are a big thing. Most carriers have some variation of callouts at 1000 and/or 500 feet if the stabilized approach criteria are met. I've heard of "1000 feet, configured" followed by "500 feet, stable"; stable callouts at one or both, and some other stuff. Criteria generally involve being within a particular window of airspeeds, within a dot on glidepath and localizer, power settings in a certain window, aircraft configured properly, and less than 1000 fpm descent. If the criteria aren't met, the callout is some variation of "1000 feet, unstable, go around" and a go around is supposed to be performed.
Unfortunately, human factors becomes an issue. Nobody wants to try to explain to the pax why they went around, they want to get their pax on the ground and on their way to their connecting flights. I have talked with people in the know who have told me that at large carriers about 1% of approaches are unstable, but only about 2-3% of "unstable" approaches result in a go-around, because the approach can still be easily saved as early as those calls are being made.
So, there is a shift happening. I believe FedEx (?) has moved to their stable/go-around final decision being moved down to 300 feet, and the CitationJet Pilots Association has what I think the entire industry will end up standardizing on eventually: 1000, 500, and 200 foot checks, but with the idea that correcting can happen except at 200 feet (I think the carriers that fly widebodies are more likely to do this at 300 feet like FedEx). You call "1000 feet, configured" if you're configured to land, or repeat "Gear, Gear" or "Flaps, Flaps" until you have the offending item corrected. At 500 feet, you meet all the criteria and call "500 feet, stable" or you repeat the offending parameter until it is corrected (Airspeed, Centerline, Glidepath, Power, Vertical Speed, etc). At 200 feet, you either have everything within parameters and call "Continue" or you call and perform "Go Around".
Finally, (and to be clear, I don't think this is in CJP's system) the criteria don't need to be the same at every point. If you need to be between Vref and Vref+15 at 200 feet, it's probably still safe to be at Vref+25 at 500 feet and Vref+40 at 1000 feet or something like that (this depends on aircraft type, of course). Knowing what the parameters are for an uncorrectable approach at 500 or 1000 can result in an earlier, safer go-around on a really bad approach.
So, how do we apply this to GA? We should have gear down prior to descending from 1,000 feet and be at no more than Vfe+10 or something like that (again, highly dependent on aircraft type). We should probably be fully configured at 500 feet and be within a reasonable number of knots of our landing speed. At 200 feet, we should be within maybe 5 knots of landing speed. For all of the above, we should be reasonably close to the desired flight path (what is "reasonable" is TBD based on the operation and aircraft type) and <1000 fpm descent.
Done right, this means that we won't be doing a ridiculous number of go-arounds, but it also means that we'll know when a go-around really is warranted (rare). During emergency drills/practice, there can be some go-arounds skipped on bad approaches, but it should then be noted after landing how that would have negatively affected a real emergency - 10 knots fast can be enough to kill people instead of just floating down the runway, for example. Basically, just ensure that the student isn't learning the wrong lesson (normalization of deviance) because they continued a bad approach and didn't die (this time).
