Y'all are a bunch of dorks!

Everybody seriously needs to relax.. The plane landed safely. You all never did a approach that wasnt by the book stabilized? I swear it's like more than half the people posting on this thread are FAA narcs.

So here's a question for ya. You forget the gear, you whitewash the checklist, and then when you go to final flaps you hear the GPWS and you lower the gear.
You utter an expletive, lower the gear, and get three green. Do you go around? I know my answer. I can tell you with certainty that some (if not all) airplanes do not send FOQA data unless/until you land from an unstabilized approach. Go-around and the data goes to the circular file. This may not be true for every airplane, but it is certainly food for thought. Pipe |

Ok, I'll try again. My point was that there seems to be a normalization of doing descent/decel planning to be stable right at 500' if VMC. If everyone just targeted stable at 1K instead, you wouldn't have this video. The complaint I hear about doing this is "you're slowing down too early!"
If 120kts (Vapp) at 1K instead of 180kts at 1K, what's it really cost in time? Assuming both situations would be 120kts at 500', you have 500' to play with. Also, making the math really simple, I'm assuming an instantaneous decel from 180kts to 120kts right at 500'. Three degree glide path is 314'/nm, so 500'=1.6nm. Compare the difference in time to travel this 1.6nm at 120kts (48 sec) vs 180kts (32 sec). I just don't get the cavalier attitudes I see regarding stable approaches and the willingness most display to say "close enough". All over less than 16 seconds?... If you routinely target stable at 1K, you've at least got a fighting chance to make it with the Mempho 30kt tailwinds. Fly however you want, it just doesn't make any sense to me. |

:confused: I'm not sure why you would "imagine" there's not much difference. A single engine approach in an MD-10-10 is a pretty big deal. It can barely get out of its own way with 3 engines. Losing 66% of your available thrust tends to be a big deal on any aircraft, IMO.
With an of the MD-11/-10 family a two-engine out approach is significantly different than just one engine out. It's a slats only approach, airspeeds are significantly higher, no auto-throttles during landing and no go-around option once the gear is down or the aircraft is below 1000' AGL. Single engine out is a non-event in comparison. Normal flap settings and speeds and auto-land is even an option. The other comments in my post were referring to a three engined aircraft with one engine out ("one out of three"). Maybe you thought I meant one out of three was running? I could see that perhaps. And yes, that would be a pretty big deal. I was trying to say that a one-engine inop in something like a 75 or 76 would be a much bigger deal than having just one engine fail in an MD 11. You're stating my exact point, with one engine out, it's not much of an event. It's significant, but not a significant change in how you fly. |

You debrief and figure out what got you into that position. And then you file an ASAP report when you get to your hotel room so that whatever stupidity put you on an unstable approach can be reviewed so that the next poor bastard walking in your shoes doesn't end up in the same position. Mistakes happen. Good pilots learn from them. |

We fly hours and hours and then paint ourselves in a corner over 15 seconds? Just dumb.
Best thing said yet ! ;) |
Just curious...and, I'm certainly not condoning that type of approach...But, do you guys really think that approach and landing were unsafe?
For the most part all I've heard on here are references to FOQA and ASAPs. Which leads me to the conclusion you're not really worried about the safety aspect of it...but, more the legality of it. |

Yes there is doubt they were rushed or gaffed off a checklist. I see an aircraft flown on glidepath on speed. The gear likely came down late rushed/gaffed or more likely distracted. They likely pushed the 500' target and if that is the case they probably should have gone around. In the cockpit they made the decision that the approach was safe and what do you know, they were right.
The rest is between them and the company. None of my business. |

I guess you could program it to flag any approach not stable below 1000' and 500' and listen to the voice recorder to determine if the intent was to be stable by 1000 or 500.

The rest is between them and the company. None of my business. Lag, You saying they "decided" the approach was safe has about the same level of assumption as me saying they were totally distracted by their lack of gear in the last 300' of the approach and were most likely paying attention to little else. Stabilized approach criteria is supposed to be more than just a square to fill so you're "legal". If you're stable before you enter the last 500-1000 feet of the approach, you are in a better position to: Notice windshear (pitch, VSI, airspeed changes meeting the limits) Scan the runway for incursions Process radio calls Actually monitor as the PM Notice/deal with malfunctions .....and I'm sure folks could add more. There's no way you're in the best position to deal with issues in the last few miles if your gear is in transit, your flaps are not yet at their final setting, your power is moving, your airspeed is not at Vapp and your PM is still finishing up the checklist. At the very minimum, the fact that you know you're pressing or past the accepted limits is in itself a distraction. Obviously everything can and often will work out in spite of a bad approach but only because things stay "normal". We can't know what would have happened if these guys had been thrown a curve ball in the last few seconds. |
Yep, you're right. It is safer to be stabilized at 500ft. And, even more safe to be stabilized at 1000ft. Probably safer yet to be stabilized 30 miles out at 10,000ft.
It's also safer to drive your car at the speed limit, rather than 10 over.(Except on I-240, of course) But, most of us do it. And, we don't consider it unsafe. Again, I'm not condoning the planning of this type of approach. I went through too many power off, over the fence at +30kts while extending flaps in the flare with the old timers here, to want to go back to that technique. My question was do all of you really think THIS approach was actually unsafe or was it just not within the parameters of our stabilized approach requirement? Is it unsafe to be configured, on G/S and +15kts at 500ft? How about +12kts? Is it unsafe to say "Before landing checklist complete" at 450ft? Hey! Maybe this clip was taken before we had the "stabilized approach" criteria. |

just went back and looked at the fleet status. This aircraft has a hud installed as of the latest fleet status which is before the date on the video. The acft in the video does not. Old video. Who knows when this was taken. Doesn't make it right but it does make it old.

Look more closely. Full screen on my iPad, I barely can make out a black "dot" under the Capt's front windscreen at about the 30sec mark of the video.

Apparently all the money the company spent on Threat & Error Management, Blue Threat during CQ and the spiffy posters about "Don't Hint, Don't Hope" was wasted on you since only the outcome seems to matter in your world... Not picking a fight, but I find it almost unbelievable that a professional aviator at our airline with our history would even ask that question.
Seriously...I think you'd be hard pressed to find many line pilots that think all the money spent on Blue Threat training and all the fancy magazines, books, etc., is worth it. So far, the meaningful information could have been condensed into about 4hrs of GS. I do play by the rules. And, my approaches meet the stabilized criteria. My point is that somebody(?) decided that 500ft was the minimum altitude to be stabilized for VMC conditions. It's an arbitrary number. Doesn't necessarily mean that less than that is unsafe. It just means that's our rule. What if the number they came up with for a stabilized altitude had been 700ft? Would not being stable at 600ft be unsafe? |

Unlike the FAR example, being stable earlier on an approach rather than later does actually make a safer approach. Maybe your airplane has an automated callout at 600' or 700', but mine doesn't. Mine only has them at 1K and every 100' interval starting at 500'. Seems that might be a great reason to pick that "arbitrary number". I'm not sure if you're just arguing for arguements sake, or you really think pushing this approach is defensible. Hope it's the former. |
Another thing there SkyKing...By waiting to put the gear down until 150ft, he's going to have that much better performance for a go-around. If they should run into windshear or have a runway incursion.:rolleyes:

(<--- Not without sin.) (from what we see in this video & not having the cockpit tapes and/or FDR to go with it - as I stated earlier - "anything is possible") The end (outcome = didn't crash or land gear up) doesn't justify the means. P.S. whether this approach was filmed before the FOM-directed "stabilized approach" criteria being implemented or not does not make it any more or less safe. Legality is a different question all-together. Definitely unsafe. Great discussion here about it too. |
Pretty obvious to me this video is just the last bit of what was a $hit hot break ("overhead" for you USAF types). Prolly 450 at the initial, 4G break at the numbers, dude finally got it slowed to gear speed on short final.
I'd call it: SHB (HFWUX) (\IM) (LOBIC-AR) OK pass. |

John Wayne in the break- Slim Pickens in the groove. Got one of those in the training command:( |

Anyone else notice that at 10 seconds before touchdown they were 2 dots low on the glide slope, about 24 knots fast, and had the incorrect incorrect crosswind correction??
