Jeju Air 737-800 gear up landing slams into wall

Here’s the thing about EMAS. It’s not the end-all, be all. It’s not designed for high speed engagements and would’ve done nothing in this case. EMAS is for fairly lower speed departures off the end of the runway, typically below about 80 knots or so. That’s it. It’s not a 61QSII/BAK-15 style departure end barrier that can be engaged at nearly 200 knots.

I wondered that I was typing it out. I suppose it might not sink much at that rate of speed. Thanks

That and the EMAS bed would be destroyed at higher than rated speeds, rendering it ineffective. The EMAS bed isn’t that long, so a high speed aircraft would sail through it, destroying it as it passes through.
 
EMAS is expensive to have for an airport that doesn’t really require it, ie- those that don’t have short runways, don’t have cliffs or severe downhills at the end, or don’t have heavy commercial/residential infrastructure right off the end of the runway. Places that aren’t Charleston, WV, or West Palm Beach, or Chicago-Midway.

I get that, but they don’t seem shy to spend money on infrastructure.

The “follow the greens” taxi system in ICN should be the world standard. You call for taxi and the centerline lights in front of you light up and you follow them. The clearance they give you is literally just to follow the greens to wherever they want you to go.

They’re redoing one if the runways at the moment, but when there isn’t construction going on they generally have, at most, 3-5 NOTAMS.
 
Buddy of mine was telling me the earthen dirt berm around the reinforced concrete LOC antenna base that was at the air bases there such as Seosan and Suwon that ive seen, is for typhoon damage protection. Having had those systems destroyed during damaging winds and rain.
 
More than once, I’ve had a sim situation where I’ve said “We’re gonna continue and land straight ahead”, and the sim instructor whispers in my ear “Go ahead and go-around anyway”.

In the debrief, instructor says “That was a solid, real-world decision you made, but I just wanted to see a single-engine GA and watch you guys work the problem”.

There’s no really good way to set that up. Maybe call a truck on the rwy and bang the motor on the go? 🤷‍♂️
 
You're on final approach at 1,700 feet and you hit some birds and one engine goes bang, what do you do?

I'm not typed on the 737 but my instinct says "gear down, declare the emergency and land on the runway you're already lined up and configured for". Besides being totally unstable or a gear extension malfunction, why initiate a go-around and then attempt a downwind landing? Just doesn't make sense.
Flaps 15, bug +15 knots, turn the autobrakes to max if you're worried about landing distance, land.
 
One notable time, waaaaay back (1999), I was in a BE99 sim in BUR (go figure). We had an engine issue on approach into LAX. Once we worked the problem and were all set to land, I decided to try and earn a little extra credit:

To FO: “Call company on 2 and let ‘em know the plane will be down in LAX”.
IP: “AMFXXX, bring the plane back to BUR”
Me: “Unable”
(Tooling around SoCal single-engine in IMC for company convenience seemed like a bad idea)
IP: “AMFXXX, bring the plane back to BUR”
Me: “Unable”
IP: “AMFXXX, bring the plane back to…” Click.
(I reached up and turned off VHF #2)

Sim goes dark, and I wake up in the CPO…😂😂😂

Our 737 shop has a section for engine failure on final approach. Bottom line, continue with flaps set to 15.


I don't think that's a bad idea, but any airline sim instructor would have a cow if you did that.


Um, why?



You’re lined up to land. One motor still going. The runway is right there. What do you possibly hope to accomplish by doing a single engine go around?

Barring some runway length issue where a flaps 15 landing isn’t possible, I don’t see the problem. Luckily our manual allows us to continue and land.

I was peripherally involved with the PSA overrun in CRW. Zodiac is pretty much the only US manufacturer of emas, and they certify theirs for stopping aircraft traveling up to 55 knots. That CRJ was going considerably faster when it entered the emas and stopped 130 feet in.
 
Plowing through the approach lighting system as well as the LOC antenna would’ve likely had a similar outcome, along with any kind of ditch or such. I remember at Seosan AB had similar slightly raised mounts for the LOC, as well as a low raised berm around the runway perimeter.

Throughout the history of modern jet transport aviation, there is a pretty high correlation between coming in contact with a LOC antenna (either on approach or aborted takeoff) and most people ending up dead. And if you are in the cockpit, I think its nearly 100% death rate. Has happened too many times to even list here

The shots I've seen of the perimeter fence, show it as a pretty robust installation, Certainly not a chain link regular. More Prison yard I bean construction. with razor wire in abundance.
When I saw it I wondered if it is a dystopian zombie apocalypse just outside the airport grounds.

It may not have been as bad, but it still would have been very bad

disregard, it seems well covered upthread already,

on another note, sign language lady sure likes the "Hang loose Hawaii" gesture

I’m sure there a small fudge factor in there speed-wise where it will still work. The manufacturers probably keep the cert speed a little lower if only for liability reasons.
 
I hate to say it, but there are A LOT of airports in the US where if you have an overrun, you’re dead, especially with encroachment by residential and commercial structures.

Show me a nice buffer zone around an airport and I’ll show you a developer successfully glad-handing the city council for variance to build there. Here’s looking at you, Scottsdale Airpark.

We certainly have had a number of seemingly survivable accidents make fatal because of berms, fences, tree lines off the departure end, etc.

I would say most airports.

CRW is one of my last picks to land short or long, in the lower 48 at least.
