ƒ{ Identify the difference between a displaced threshold and a clear way.

Ans: Displaced Thresholds are useable for takeoffs and landing roll outs. Clearways [I think] is hard surface but are unuseable.
Am I getting it confused with a stopway??

Huh?

I might be wrong, but isn't a clearway a form of airspace?

Let's see how to define it...Hmmm. Maybe "The airspace extending from some point on a departure runway encompassing a 2-3 degree flight path (I'm not sure which) up to an altitude of 400' AGL".

I might be confusing terms with something else, but I do think a clearway has something to do with a certain climb gradient, either on one or two engines to a certain altitude at a certain distance from either the point of lift off or from the departure end of the runway.

A displaced threshold, OTOH, is a paved surface that can be used for taxi and takeoff but not for landing (identified by chevrons pointing you toward where you may land). And a stopway (I think) is something you can roll out on but not use for other purposes.

I'll be interested to hear anybody else's definitions.

Just search on "clearway" (cwy) and it will take you to the appropriate AC.

I think you are confusing a clearway with an overrun. My understanding is that clearway is just a path for low flight beyond either end of the runway.

Great Help...

As always, you're right on the money. Tha's why you're paid the BIG bucks eh?

It's now easier to recall during the interview.

CLEARWAY - Think of it as the terrain adjoing the end of the runway.

STOPWAY - That's the Surface centered and extending beyond the usuable runway. Especially applied during RTO's.

Is a stopway sometimes composed of that special "soft" concrete that is supposed to stop a plane? I understand that it's supposed to be a last ditch effort to stop the plane (with minimal damage) before things really get ugly and the plane goes into the lights, the mud, or the drink. I think that JFK has them on some of their runways, and they have be used a few times (didn't Jetblue have one when they were still learning?). Anybody know more about this type of thing?

"(didn't Jetblue have one when they were still learning?)"

O no, now you've done it, you've bashed JB, now you gonna get wacked by the "JB police", nice knowing you.

BTW, I think they went off the side of the runway not the end, it was a few years ago after they had just started. Gemini went off the end last year in JFK, the picture I remember seeing on TV is the nsewheel of the MD into the "soft concrete".

And for future advice, don't ever call JB's ERJ-190's "regional jets", we don't want to crack open that can of worms again, do we?

Ernest,

You're worrying too much about the wrong questions. HR is where most folks blow it.

What's your reply for:

"Tell me about your weaknesses". "Now tell me another".

"Tell me what you like about your boss?" What don't you like?"

"When have you gone above and beyond to give someone outstanding customer service?"

"Tell me about a day that started bad and ended good (or good to bad)."

If they interview you, they know your basic qualifications. They really want to know if you are someone they want to be around for 4 days straight.

good luck,
Catfish
