Hello;On landing, what is the correct throttle procedure assuming that the AT is set to on.As the aircraft touches the ground the AT is automatically disengaged, then you engage the reverse throttle. At what point or at what time do you close the spoilers? Thanks, Iain

You close the spoilers as soon as you exit the runway.

Normally the spoilers are programed to close automatically as soon as you give some thrust to the airplane.

Unless you idle your way into the gates.

Thank you for clarifying this issue.Yes, when I add some thrust after landing they auto deploy. Iain

The spoiler auto retract is based off of throttle lever angle. So when clearing the runway after the captain calls for the flaps up he'll usually push one or both of the throttle levers about half way up and pull it right back to idle and the spoilers retract before the engine has time to spool up. Some just push the spoiler lever back to the retracted position. It's really just personal preference how you choose to retract them. Generally you don't want to run the reversers below 80 knots unless you're going off the end of the runway. Above 80 knots the relative wind is keeping any of the fod from reaching the intake. Below that you risk the reverse thrust thowing any debris that might be on the runway far enough forward that the engine which is at high power might ingest.Hiram Hunt

I have a few videos (5?) from a trip this last winter on New Mexico One of SWA. (NG for those who don't know.)Anyway, I don't know what happened with the spoilers, but normally, as stated previously in this thread, the flaps and spoilers are retracted together when vacating the runway. However on this flight, upon landing in BWI, the spoilers were not retracted once we vacated the runway. In fact we taxied all the way to the GATE, and they were STILL deployed. It was not a thrustless (idle thrust) taxi. In fact, we came to a stop, and the engines were SHUT DOWN, and the spoilers were STILL deployed. Only after the door was opened were the spoilers finally retracted. It makes me wonder if they were perhaps overlooked, or if it had to do with icing seeing as it was freezing outside. If there is any interest in these videos, I will consider uploading them. The same BWI landing shows a highspeed, very low vis approach. (it was cool because you couldn't see the ground, but you could tell/feel that you were going faster than normal. Spoilers were used all the way down, and the gear was extended before the flaps in order to slow to acceptable flap extension speed. Neat!) I also have BHM departure, BWI de-ice, etc.

You're positive the spoilers were actually out for the entire approach? That's against actual Boeing policy - they're supposed to be retracted past flaps 10...

Go ahead up them. Would be interesting.On a side note though, ain't that a little weird to retract speed brakes after engine shutdown. I don't know for how long hyd px stays up (I don't suppose it's long...) but I'm pretty convinced the speed brakes needed at least some px in order to retract. And the elec pumps are usually not running when parked either.How could you tell you were faster than normal though, especially if you could not see the ground?Would appreciate the footage though! :(

No they weren't. Sorry, I wasn't clear. I said "all the way down", which was my mistake. What I meant was all the way down the initial descent. They were retracted for flap extension. Sorry, I knew what I meant, but I didn't make that bit clear.

Yea, I thought it was weird too. That was precisely my reason for posting this. I'd have to watch the bid again, but I thing the engines were spoiling down, or had just spooled down when the were retracted. Makes me think maybe that maybe when they reached for the shutoff levers that they noticed the spoiler handle?About the speed during descent: just to clarify, landing speed was normal, descent/approach speed was high. As I said, it was low vis, but being a very frequent flyer (AA Platinum Baby!) I noticed that it FELT considerably faster. You may say that this is silly, but I don't think it is. Anyway, upon feeling that we were fast, I pulled out my *cough* *cough* iPhone even though electronic devices were supposed to be *cough* off. Aaaanyway, I have an app that my friend who is a captain at SWA showed me and said to be quite close to accurate. (don't remember the name, id have to look) so I started this app (which uses several GPS signals to provide the data) and checked out what it said. At 7000ft the app said 290kts. At 5000ft the app said 240kts. We were 3000ft at 190kts. Decent rate varied but was between 1800 and 3200 depending on how close we were to the airport. Keep in mind that this is from an iPhone app so it's not going to be 100% accurate. Also the gear was extended before the flaps and while the spoilers were still extended.

Interesting. No I don't think it's silly at all, I just wondered. But now you got me even more curious - care to check out that app's name? Feel free to PM as well if you don't want to post here or so. I'd certainly like to have a look at it. Does it allow feet and knots to be used as units of measure directly? Would be cool.

I too would be interested in the title of the app

Very interesting indeed. I was once arriving in London, EGLL, and the Virgin 744 that I was on taxied practically all the way to the gate with spoilers deployed/up. It was quite confusing as I thought they would have been retracted once power increased (although I guess it could have been an idle taxi).I would also be interested in the app if you can remember it.

Hi peeps!I looked, but the app I had is no longer in the app store. It must have been removed? Anyhow, I see a similar app to what I was using at the time. It is called Flight Instruments. http://itunes.apple.com/us/app/flight-instruments-gyro-attitude/id390596737?mt=8I have no idea if it works as well as the one I was using before or not, but it looks like it does basically the same thing. Though the one I was using has more features, and looks better. Anywho.... There ya go. =)I'll see if I can upload those vids. I might not be able to do it until tonight because uploading uses all my bandwidth, and I have to work today, even though its Sunday. Bummer...
