Why EMAS is good

What you don't see is the huge dropoff 100 feet off the nose that is at the end of Runway 23 in CRW.

Word is everybody is ok.

The question if the aircraft is in one of the new extensions at the airport...

Yeager Runway Closed After Plane Aborted Takeoff

CHARLESTON -- A runway at Yeager Airport is closed after a plane skidded off the runway. When the pilot aborted takeoff, the plane skidded into a soft sandy emergency area where the plane became stuck.
It happened around 4:30 p.m. Tuesday afternoon.
According to Brian Belcher with Yeager Airport, a U.S Airways plane carrying 30 passengers was attempting to take off from Charleston to Charlotte when the had to abort the takeoff.
The 50 passenger aircraft is a Canadair Regional Jet with 30 passengers and three crew members on board, according to a press release from Yeager Airport.
No injuries were reported and the passengers were transported back to the terminal, according to the release.
Airport officials confirm the runway will remain closed until the aircraft can be cleared from the runway.
 
Any rumors on how fast they were going when they initiated the abort?

I've always been skeptical about whether you could really stop on a runway at V1 minus one knot. Not to say that I wouldn't abort, but there are some runways where you're chewing up real estate so fast I didn't think we'd really be able to stop.
 
Let's hope airports around the country take note and we see an increase in the implementation of EMAS. It's a great technology. I noticed the other day that it's been put in place at the departure end of RNWY 29 in EWR.

As far as I know EMAS can be included as long as it's characteristics are considered. Well "stopways" to be exact. So, when I'm looking at my numbers, I'm always very curious if a stopway was considered.

Depends on the runway, I guess. if I'm in BTR with the longest runway, I'm still pretty limited in my abort criteria.

If I'm in DFW with 13000 feet of dry pavement ahead of me on 18L, that changes things.

I did a highspeed RTO in Boston once. 7000 feet, and we used damned near all of it.

That's why you reeeeeeeeeally need to think about what you'd abort for. If it's V1 +/- a few knots, it's got to be something like "OMG, the aircraft WILL NOT fly and I'm about to pee my pants".

At our airline, we talk a lot about high speed and low speed aborts. Things that we'll abort for before 80-ish knots, things we'll abort for above 80 knots.
 
"The Pilot aborted" etc etc. I like the notion that the other dude was just sitting there like "What, why we stoppin, guy?" with his hands folded in his lap. My kind of F/O ;)

He was actaully eyes deep into the newspaper and barely noticed that the aircraft had stopped.:D:sarcasm:
 
Sorry it was only a matter of time. Glad everyone OK.

[FONT=Arial,Helvetica]Passengers Say They Were Close to Death[/FONT]

[FONT=Arial,Helvetica]Passengers aboard US Airways Flight 2495 are lucky to be alive.
The Canadair Regional Jet they were aboard came to a screeching halt just about 150 feet from the edge of a mountain.
Passengers aboard the plane said the plane accelerated but then the pilot slammed on the breaks.
The aircraft skidded down the runway until stopping just about 150 feet from the edge of a mountain.
The aircraft seats 50 people. Just 34 were onboard Tuesday. 30 passengers, one infant and 3 crew members.
Many describe the incident as surreal and frightening, to realize just how close they all were to death.

Obviously these people have never operated an automobile on an interstate highway.
 
Seeing as your location is CT, I would agree on that statement about I84 west of Hartford.

CRW has VERY interesting topography that is not found at 99.99% of the rest of the airports in the US. It seems as if they lopped of the top of a mountain so that there was 5000 feet across then pushed the dirt on a couple of edges so that there was a wee bit of safety margin from 5000 feet to a steep slope to 6000 feet and a cliff. If I remember correctly CRW has one of the ALS' strung from the hill that the airport is on to the next hill over and the valley below is 200+ feet down. Now I flew in there in a piston single, and it wasn't bad, but I'd imagine that taking a jet in there certainly has a lot of pucker factor associated with it. Its certainly one of those "screw the greaser, get the damn thing down and stopped" type of airports.

Yes, an overrun without the EMAS could have been VERY bad.

I've flown in CRW once and its REAL bad news if you go off the edge.

That's why you reeeeeeeeeally need to think about what you'd abort for. If it's V1 +/- a few knots, it's got to be something like "OMG, the aircraft WILL NOT fly and I'm about to pee my pants".

At our airline, we talk a lot about high speed and low speed aborts. Things that we'll abort for before 80-ish knots, things we'll abort for above 80 knots.

We do that at ASA as well. Our FOM basically says after 80 knts only abort if the safety of flight is compromised. In fact its been reiterated recently after several incidents of crews aborting over 80 knots for silly reasons(Pack faults, anti-skid failure:eek:).

I've always been skeptical about whether you could really stop on a runway at V1 minus one knot. Not to say that I wouldn't abort, but there are some runways where you're chewing up real estate so fast I didn't think we'd really be able to stop.

When we hit V1 in Key West I feel like I could physically jump to the end of the runway from the spot V1 is at.
 
We lost Key West before I upgraded but most captain's I flew with down there briefed V1 at 90 knots unless the wings were going to fall off. There is no way you'd be stopping in time with some of the published numbers. It's the same thing with Runway 8 in Philly and 33/15 in DC. We call V1 at V1-5 and even then, I tend to wonder some times.
 
Now this is me just thinking aloud, but if you called "V1" at V1-5 what would there be as far as protections if you lost an engine at say V1-3....?

I guess in other words, how close is V1 to Vr in these situations and how much would the lack of thrust affect your ability to takeoff before the end of the runway?
