Re: Current and future wrong runway alignment thread.

According to www.internet.com headlines, A Delta person had trouble with keeping the 14 strips of somewhat parallel concrete straight during the week of 12/11/2017. The article was a good one- seemed to be trying to embellish it to a "near total disaster" "The plane, crossed the taxiway threshold a...

Re: Smithsonian Channel Air Disasters- Atlantic Airways 670, BAE 146 Overrun.

So it was pilot error. There were several pilot errors here: - Misdiagnosed why the pane wasn't braking. - Locked the brakes (the report doesn't say it directly, but it seems from the systems and procedures description that activating the emergency brake enables the brakes to be fed by a reserve el...

Re: Smithsonian Channel Air Disasters- Atlantic Airways 670, BAE 146 Overrun.

I rest my case. The commander noticed that the aircraft was not decelerating as expected. He did not associate this with the fault in the spoilers and assumed that the problem was due to a fault in the brakes. He therefore applied the emergency brakes. The flight crew got information that both lift ...

Re: Smithsonian Channel Air Disasters- Atlantic Airways 670, BAE 146 Overrun.

Now, what is your agenda?

Re: Smithsonian Channel Air Disasters- Atlantic Airways 670, BAE 146 Overrun.

if the discussion is this crash, then the misdiagnosis of brake failure is not particularly valid. Just a reminder that for this crash, there was not a misdiagnosis.
Why not? What I was saying is that exactly the opposite is a possibility.

Re: Smithsonian Channel Air Disasters- Atlantic Airways 670, BAE 146 Overrun.

Let me set the record straight: Spoilers are a REQUIRED means of braking, as much as the brakes themselves. Airplane stopping performance is computed with the braking action generated by the weight-on-wheels after spoiling the lift with the spoilers. A landing in a perfectly legal (but marginally le...

Re: Smithsonian Channel Air Disasters- Atlantic Airways 670, BAE 146 Overrun.

I'll bet dollars to doughnuts (because both are cheap) that they *were* trained that selecting "emergency braking" does not increase braking effect and could well decrease it. Although it's easy to understand why in a moment of panic, they might think the opposite. Panic is not the only possible ex...

Re: Smithsonian Channel Air Disasters- Atlantic Airways 670, BAE 146 Overrun.

Let's see... so you land... spoilers would not deploy... due to the wing still producing a significant lift you don't have enough WOW (weight-on-wheels) and hence not enough braking action... How can you increase WOW? It is sad that no no-spoiler procedure was in place, taught or trained. There were...
