Of course we do.
We like to anticipate a worst case scenario; creating numerous unnecessary distractions might however turn into a worst case scenario.
I see your point but in my opinion distractions are very dangerous in this critical phase of flight. Also, our approach speeds simply do not allow us to make any mistakes. I've been at 4 airlines and none of them taught the 'backup approach" method.

You can be cleared for an "ILS" OR for a "LOC" if your approach plate say LOC. If such plate does not exist you'll be cleared for an "ILS glideslope OUT."
Folks, it boils down to safety but also to plain ole' common sense.
Do NOT put any extra distractions on yourselves, we have enough of those as it is and IF something were to happen, trust me, the FAA won't come to defend you to say, "well, technically I guess you can do it..."

Going missed is very simple, re-brief for a new approach, change the minimums alt. buggs, brief the new missed procedure, etc, and do it again.
You'll never get in trouble for saying, "I thought it'd be safer to go-around and give it another try..."
Just my 2¢

When is the last time you hacked the clock during an approach ?
#54
You do not start the timer so you can drop down and do the localizer approach you start the timer so you know when to go missed. Has anyone done an ILS with obstacles on both sides of centerline and the missed approach procedure has a turn? If you lose everything and immediately start the missed approach procedure you could run into a building or terrain.

Not sure I understood what you were saying here but ATC instructions are very clear, they will only clear you for one approach.
You can be cleared for an "ILS" OR for a "LOC" if your approach plate say LOC. If such plate does not exist you'll be cleared for an "ILS glideslope OUT."

Knowing what the mins for the loc are and using them as a potential backup is not remotely unsafe IMO. Do airlines teach it? I don't know, maybe maybe not. Have I ever been corrected while briefing it? Nope. What's one more number or a two second glance at an approach plate?

- At my current airline (but also other airlines I've been at) for an ILS we start dropping the flaps and the gear when the glide slope becomes alive.
- For a non-prec approach however we are supposed to be fully configured by the time we hit the final approach fix.
Lets say we're shooting your scenario approach where we are on an ILS, on the glide slope (past what would be the non-prec FAF - Maltese Cross) and about to ask for the last notch of flaps (in other words still slowing).
Right then we lose the GS and according to you we should now transition to a LOC approach. However, since we were not fully configured prior to the non-prec. FAF we are required to go missed (see above).
Also, if we decide to continue, the timing will be off because we're still slowing down and the time is predicated on a constant final approach speed.
What about the pilot monitoring (pilot-not-flying) call outs? Hopefully your PNF won't miss the 1,000 and 500 foot callouts (or whichever altitudes you call out on an approach).
Also, don't forget to change your minimums buggs while you're trying to get to the MDA, oh and what was that VDP again?
Can I do it? You bet you and I have done it numerous times in the past in smaller airplanes. However, would I want to do it flying passengers or packages for that matter in transport category aircraft? No way.
If you honestly believe that all those additional distractions are "not remotely unsafe" as you phrased it my hat is off for you. You're simply a better pilot than I am.
I am not saying it in a disparaging way; I simply admit that what you consider perfectly safe would be an undue distracting burden for me possibly affecting my performance.

I totally agree with a lot of your post, by all means per your airline's policies all of the opening scenarios should normally result in a missed approach.
So now lets assume that we were fully configured and on speed by the FAF (which is the policy at mine). We start down the slope and then lose it, I wouldn't have an issue with continuing down to the MDA. Maybe I had the chance to reset the bugs, maybe the PNF took care of it. But those are pilot aids and they're there to provide backup to me and to the PNF. The primary means is still either me or the PNF noting that we're at minimums and not what the little GPWS or RA or whatever particular system's voice it is on that specific plane's voice tells me. Sure you can just execute the missed and be perfectly safe and fine but I also beleive you could continue and be safe and fine. If you're flying and I'm the PNF and you chose to go missed, great, it's your perogative and I'm not gonna give you grief about it. Hey, maybe I didn't like the way it was going and I decided to go missed too. I'm sure we can both completely agree that flying is dynamic.
I'm not meaning that in a disparaging way either. I just don't like things to get to the point where the most important thing is the computer taking care of business and me watching it helplessly. I look at it this way. We may have become more simply systems managers in modern aircraft but we are all still pilots. Passengers or boxes or nothing in the back, we're still supposed to be able to fly the plane to include instruments. All those nifty toys are great additions to SA and they're great safety backups. However, they are simply pilot aids. I think they've become too much of a crutch for many people.

Are you saying that your airline's policy to have the gear down, full flaps and have already slowed down to your final approach speed prior to reaching the FAF for the non-prec. (which would be same as my airline) but also prior to intercepting the glide slope for prec. approaches? If so, are you telling me that you're flying ~130 knots or so from the moment you intercept the GS until you touch down each time you shoot an ILS?
#60
Technically, yes, we're supposed to be doing exactly that according to the profiles. 1 mile prior to the FAF for precision apps and 3 miles prior for non-precision. Our approach speed is ref+10. So we are in theory supposed to be flying anywhere between 115-135 kts all the way from the published g/s intercept altitude down to the runway in this case. In reality, you can't do that in most airports with traffic on final and not be a huge pain to everyone else in the pattern. Of course we will do whatever to help the flow of traffic - 170 to the marker, 230 to the marker, 160, whatever, and technically be in violation of our profiles and it's kind of expected.
