Here is this great video:

I guess our friends in Lion Air crash experienced something similar.

Its incredible to see there is no runway after so much clear view and the crew declaring Go around right away....

Here are some coments of the guy that captured the situation :

Quote:
"The approach flown was a CAT I ILS.

I could see the rain column approach from the other side of the field so I got out my phone camera from the jump seat.

You can hear the GPWS announce minimums at 200' AGL, and shortly after all visibility is lost due to rain. You do not hear the "50" foot call out during the touch and go, but it had to be close.

The HUD really provides incredible center-line tracking, although you can't see the symbology from the camera angle.

Ultimately, we had plenty of fuel on board and we where given radar vectors back for another approach. In just 15 minutes the rain had passed and the sun was coming out."

I've had something like this happen to me. We were flying into Yow and had a clear view of the runway all the way down to about 100 feet. All of a sudden we were in the thick of large amounts of blowing snow. It was a very weird sensation but it was previously reported and knew it would happen. Good job by this crew who were taken by surprise when the visibility went to nil.

This kind of rain is what we face regularly... some on the Lion DPS crash topic didn't believe that something like this don't or cannot happen... it does. Sometimes get this, do one go-around, and before you reach the holding point to start the approach again, the rain disappears already.

The difference between this crew and the Lion Air crew is that one called the go-around in time.

While training for my Instrument rating my instructor would pull this kind of stuff on me in the simulators. I always thought it was BS being able to see the runway all the way until minimums and the have it vanish.

Amazing video!

You're partially correct.

A CAT I ILS does not have a DH, but a CAT I ILS *does* have a DA (decision altitude), not an MDA. Functionally, DA/DH are essentially the same thing except the DA is MSL and is measured only by the altimeter whereas a DH is AGL and requires a radar altimeter. MDA (minimum descent altitude) is only for non-precision approaches.

I don't think Slat Retraction would cause a Master Caution. That's a normal crew selected state. Boeing's philosophy is that you don't alert the crew to normal stuff - quiet and dark cockpit.

I don't know the 737 very well since it's a non-EICAS airplane. Is that how they annunciate Altitude Alert?

It's not necessarily a limitation of the aircraft. Many smaller airports only have CAT I ILS procedures due to the limitations on their equipment.

I'm not positive, but are you referring to the HUD (Heads Up Display)? If so, it displays information for the pilot on a see-through screen so they can see critical flight information without having to go "head down" to look at the cockpit instruments. From the angle of the video, it doesn't look like anything is there, but it is.

The CAT 1 ILS usually has a DH of 200' reference to the runway, however that 200' is not 200' below the aircraft at the point we need to go around. You cannot use the 200' figure as that is not how the chart is designed.

Imagine an runway on a volcanic island 1000' above water with almost a vertical drop at the end of the runway to the sea below. The chart will have a MDA(DH) or DA(DH) on the chart depends on who you use to supply your charts and it might say 1200 (200). If you were go wait until your RADALT read 200' you would hit the runway, or the cliff before it, as at the MDA/DA you should be going around at an altitude of 1200' which is 200' above the 1000' runway when on the glideslope. It is the intersection of that altimeter reading and the glideslope which makes the triangle to give you 200' above the runway.

At a different airport, which they have suitable terrain leading up to the runway which has been surveyed with a CAT 2 approach, we would go around at around 100' reference the runway, on the chart it might read 100 (115) we use the 115 figure at that is the height the RADALT will read over the terrain when the aircraft 100' above the runway when on the glideslope.

This gets blurred a little where some people have special authorizations based upon HUDs etc, I am just referring to the standard rules.

Quoting MountainFlyer (Reply 15):

MDA=DA where vertical guidance is available.

Quoting MountainFlyer (Reply 15):
MDA (minimum descent altitude) is only for non-precision approaches.

I think you are quoting a FAA AIM defn, which is not universal. The universal defn is MDA=DA where vertical guidance is available, which covers various approach types. This gets the brain thinking in term of altitude in case the GS fails, one can revert to the LOC.

I think in the US they say the FAF=FAP which is not universal either.

Anything I think below 9 seats and 12500 lb/ 5700 kg I do not think was required. Something like a King Air B200, CAT 1 ILS in the olden days with things called marker beacons.....

Somewhat interesting video. Any pilot/crew worth his salt should be able to go around/missed approach anytime up to just prior to touchdown and make it a non event. CAT IIIa and IIIb missed approaches are routinely done from 50 feet and 35 feet.
HUD is one of the key safety innovations in recent years. The flying pilot pilot stays heads up through out all phases of flight. Including during the critical phase of instruments to visual or visual to instruments.

At the risk of going slightly off topic...

I was sruck by the fact that the pilot had a HUD.

I know that HUD's have been used in military aircraft for some time now... it has always struck me as odd that they haven't been adopted widely in civilian use. Just yesterday I was reading a thread about joystick v. wheel in Tech/Ops, where several posts referred to the pilot's need to drop his or her eyes to instruments, referring to the fact that this can cause distraction at a critical moment.

I do recall seeing a HUD is the CSeries cockpit mockup, and now apparently the Boeing BBJ also. Are there any other aircraft out there that come equipped with HUDs?

787 has dual HUD as baseline. It's been optional on the 737 for years, not just the BBJ. AS, WN, AA and I think DL have them on all their 737s, among other airlines, AFAIK. I think FedEx puts them on their 777s. Heck, AS had them on their 727s and PSA had them on their MD-80s so they certainly aren't a new thing either.

I think HUD's are on a lot more airplanes than you realized.

Plenty of airliners have HUDs now. As the post above says a few airliners they are normal equipment now and many airline have installed them on their planes. Not that uncommon these days.

You are correct, the Master Caution will only alert for an abnormal state.

Quoting BoeingGuy (Reply 16):

No, the Altitude Alert is a horn with an annunciation on the PFD. This is clearly a Master Caution with what appears to be an associated FLT CONT. Look at the "6 pack" immediately to the right of the Master Caution. The amber Master Caution light will alert you, while the 6 pack informs you as to what has malfunctioned. The 6 pack is configured to roughly match the overhead panel. The first item in the upper left on the Captains side is FLT CONT.

Very strange. The only time I've seen that on a go-around is during gear retraction with a degraded A hydraulic system. If the engine driven A hydraulic pump has failed, the electric driven A pump will suffer a momentary drop in pressure as the gear retracts, causing a momentary FLT CONT master caution.

Look at the pic here;

I am not a pilot, but IMO, the pilot's action was spot on.

Even if he was on the runway centreline, he would have landed very long, (he was almost over the threshold at decision height).

If you add a runway that was wet, (possibly more like a lake) then he would probably have been straight off.

IMO, if you have enough fuel to GA, then why take a chance.

My understanding:

DA (DH) = point on a GS where the MDA equals the MAP.

Once you arrive at an MDA, you can stay at that altitude until the MAP. That of course would make no sense if you are on a GS.

Am I wrong? I've only read about this stuff. . .

Correct - that is the altitude alert horn.

I was able to hear the "flaps up" call just prior to the FLT CONT master caution. This would indicate a possible abnormality with the B system hydraulics.
