I’m not sure if this accident counts as a “runway excursion” as they don’t seem to have touched the runway, but there have been quite a number of runway excursions over the last few years. They don’t seem to get the national publicity as to date the last fatality was the SWA over run at MDW, but if we keep this up there may well be another.

This is a really easy job. Until it isn’t.

You land in the dirt, total the airplane with injuries is a crash!

At the reported half mile visibility this aircraft should have been AT MOST 136 feet off the centerline. At the MDA for a localizer approach at PQI being 70 feet to either side of the centerline of the 150 foot wide runway ought to have given a full scale needle deflection.

If anyone is seriously saying that they ROUTINELY experience a lateral deviation of 100 feet at the mins they are either full scale deviation and ought to be going around or they are flying an aircraft that has instrumentation that is seriously out of tolerances and needs to be written up.

Of course it's a write up and an asap after the underwear is cleaned. And yes no the error that had been seen on our fleet is loc has zero deflection and we are breaking out not aligned... I can't speak for c5s fleet. This is being investigated for us. Wr also have a problem where the loc cdi swings right and left full scale throughout the approach.

Does the 145 have a false capture problem like the crj200?

Having flown the CRJ as an FO and CA for several years, what are you taking about? It would act a bit flakey on the LOC sometimes, but I never had a false GS capture, nor have I ever heard of this on the CRJ.

I think he meant false capture on the LOC. To clarify, I’ve never seen a false capture on a full ILS in the 145. Generally speaking, the 145 AP does a good job when holding both the LOC and the GS. If you’re seeing more than 1/2 dot deviation inside 500 ft while coupled to AP, then there’s a problem and a GA should be initiated. Like I said, this wouldn’t have anything to do with actually putting the airplane down the in the snow. The TD zone needs to be indentified before landing.

According to Sully, he performed a water landing.

With 4000 hours on the CRJ, I’ve had it several times. Both LOC and GS. I’ve seen the airplane abruptly pitch 10° nose down to catch a false glideslope. I’ve seen it track the localizer inbound when I was still 4 miles away from the localizer course many times.

Just because it hasn’t happened to you doesn’t mean it hasn’t happened.

Just because it happened to you....on a plane that isn’t relevant to the situation.....doesn’t mean it justifies plowing a field with an airplane instead of going around.

It happens on the CRJ sometimes with parallel runways. Specifically in IAD if you are landing on a center runway and arm the approach before passing the outside runway the aircraft will start turning towards the wrong runway.

With that said wether IMC or VMC your situational awareness should let you know if your aircraft is turning the wrong direction.

If the runway was that bad there is a great alternate 100 miles or so to the south, Bangor, ME. Time to use that command decision as the CA and do what’s safe.

Pax reported a bounce. They may have initially hit on the RWY and then bounced off.
