It established the habit pattern early and can be consistent in any platform.
I've only seen the 5 T's in this order:
Turn
Time
Twist
Throttle
Talk

Never thought about track. Interesting.

I would like to suggest that making a missed approach to us is considered a quasi emergency. This may sound funny but we don’t do them that often in the real world and they are time consuming and expensive. Having said that I would also imply that you should be thoroughly briefed before an approach. If you expect that the weather will allow you to see the runway with the ILS and not just MDA then it may not be a bad idea to go-around. But it would be nice to know that all you need is get to the LOC MDA and one step down would have gotten you there. And if you think that making a missed approach is no big deal then explain that to the 182 folks that have connections in DEN. You should consider it a big deal when you are not prepared for a few contingencies. Next , WE will talk about CAT 2/3 approaches.

I find it highly amusing to see a bunch of pilots arguing over SOP.

On the topic of CAT-2/3 approaches, could you even execute a 3 without the GS (i.e., would autoland work?) Just my noobish question.

No, it needs the GS for guidance to start down but can continue to the runway from 100' agl if GS is lost using the radar altimeter.

Thanks, that's what I thought, I guess it works much like the APP in that aspect. Makes sense.

How many ppl. here have ever flown a CAT-IIIC approach? I have (on FSX until sometime in the near future.)

It took me 14 years to fly a CAT III approach and that was in a Level D sim. I don't think any regionals go lower than CAT II right now...so it may be a little longer than you think.

Flying Localizer procedures when cleared an ILS will often surprise ATC as it may set off their low altitude alert system, distracting them and having extra radio calls and losing cool points. If you choose to tell ATC you are practicing the LOC then they have a heads up that you may dive to the MDA, setting off the Low Alt. alert, then drive in... Actual mileage may vary, along w/ what your local ATC prefers. The AIM/PCG doesn't cover this training scenario, and you'll have to disregard that operating GS as you duck under and get the "GS" GPWS warnings. Pretty normal in the USAF heavy training pattern.

R U telling us that AF C17s actually do dive and drives still? Why not use a vnav or profile down to MDA? For the past nine years, the FAA has recommended that a vertical nav mode be used in lieu of d&d's if available (think of ythe passenger jet scraping trees in BDL during a D&D). Jepp has been publishing vnav path info on approaches since that circular for those of us lucky enough to have vnav inside the FAF.

Youbetcha, and you just preached to the choir.. Uncle Sugar and your tax $ is Just getting the jet to where you can pick and fly an approach and use WAAS/LPVs. Yes, good pilots make them 300 '/nm or so stabilized descents obstacle/MDA permitting, use VDPs, etc- but we don't fly either self contained or GPS/LPV just quite yet. I've been big on not just diving and driving myself...

I thought this was a good thread with a lot of good information in it that is worth a refresher - though the part quoted above does have a recent change associated with it that takes affect in June 3 '13.

An aircraft conducting an ILS or LDA approach when the glideslope is reported out of service must be advised at the time an approach clearance is issued unless the title of the published approach procedure allows (for example, ILS Rwy 05 or LOC Rwy 05).

"Cleared I-L-S Runway Three-Six Approach, glideslope unusable."

I'm not sure what has changed from the older version of the order, but this is marked as new in
N JO 7110.615.
