What is a good descent rate in an A319?

Hi,

I am currently flying an A319 - desending from 23,000 to 5,000 before finals.

What is a average descent rate in one of these aircraft? I am coming down between 1300 and 1800ft/m - should I be coming down less or more?

Thanks

Have a read of this link:

Descent rates vary with distance from the runway, but anything up to 2200fpm (without spoilers) is good 😉

I have never flown one, but with any plane, I would read what the recomended decent rate is. OK, I know you probably won't do that, so at least keep it under a rate that you can still control your speed at. You should always be able to slow down with your throttles.

99jolegg, spoilers are the same as speedbrakes aren't they? As in, little slits that you can deploy during flight which "spoil" the airflow over the wing and therefore slow down the plane?

So when you say with no spoilers, do you just mean that you should be descending at a rate that doesn't cause his speed to go up so much that he needs brakes?

Thanks a lot for any help clearing this up!

...spoilers are the same as speedbrakes aren't they?

Negative. This is an excerpt from Wikipedia on the subject:

Spoilers differ from airbrakes in that airbrakes are designed to increase drag while making little change to lift, while spoilers greatly reduce lift while making only a moderate increase in drag.

Yes. If your speed increases at idle thrust when you are descending, then you are descending too fast. If that cannot be helped, i.e. you must descend quickly, then use the spoilers and you can descend a lot faster without increasing speed 😉

So... spoilers make you descend faster, but speedbrakes just make you slow down faster?

Could anyone explain what each of these look like/how they work? Thanks a lot!

we'll be done soon then, as the two are the same thing Wink
In FS2004, by default, you deploy the spoilers pressing " / "

If you've ever sat close to a wing of a plane when landing; the spoilers (a.k.a speedbrakes) are the'plates'(by lack of a better word) on the upper side of the wing that (usually) pop up the moment the plane settles on the runway; greatly increasing drag, and thus slowing the plane down at a faste rate than it normally would.

Same goes when you're in the air, the increase in drag when spoilers are deployed will slow you down a lot, enabling you to descend faster if necessary, as jolegg explained above. 🙂

So... spoilers and speedbrakes are the same thing? 😕

And spoilers (also known as speedbrakes) are used OCCASIONALLY in the air when a pilot wants to descend quicker without increasing speed but ALWAYS used when the pilot touches down on the tarmac to slow the plane down? Is that all correct?

Thanks a lot once again for any help!

I think so too. I noticed quite a few times sitting by the window near the wing. The spoilers are the same plates as the airbrakes. I got a question for you guys, what do the slats do? just like wing flaps on the front edges of the wings?

bear one more thing in mind that decent rate has something to do with your passenger comfort. at thing faster than 2000 will make earpopping unbearable, or even pain......make sure dont get complaints from your pax 🙂

spoilers are not only used for beaking, right after landing it cuts the proper airflow so that wing doesn't produce any force that makes the plane able to fly. Sometimes the speed can be little bit more than 'on the edge' right before stall. it helps to stabilize the plane on the ground with high speed.
