View Full Version : DF-737 spoilers

Does someone know how to make the spoilers deploy faster?. It seems not very realistic to me as it is by default in FS2002.(very sloooow)

I think the spoilers deploy fast enough. I takes them about two seconds to fully deploy.
Anyway, I'm no aircraft expert but I don't think, you can change their speed since this is defined in the MDL file.

Thanks for the reply, Hans.
But as I recall from real flight, the spoilers are also used as airbrakes, and can be deployed and retracted very fast and in any position between retracted and fully deployed.
This is certainly not possible in MSFS, I think.
Correct me, someone, if I'm wrong.

have you tried dragging the spoiler lever with the mouse, you can set any spoiler setting you want?
Spoilers may be used as airbrakes, but it's not their design purpose and their deployment does take about two seconds from none to full. Maybe what you have seen is just partial deployment? It would not normally be required to use full spoilers except on short runways where the lift needs to be killed to get the weight on the tyres for the autobraking to be maximised together with r/thrust.

Check out the .air file record 1101 spoiler cycle time.

I guess you are right about partial deployment in flight (as a passenger you can feel the effect).Still , I think the retraction is pretty fast, but I'll watch for it very carefully, this summerholiday when flying to Greece.Landing with a 737 on Chios or Lesbos)(VOR-approach) , as I eperienced before(as passenger)is fantastic!

I'll take a look at it , not sure though how you have to edit it.

They can be extended and retracted almost as fast as you can move the lever. “Technique” suggests other, though. If you actuate the handle (spoilers) rapidly, you feel a very distinct “settling” in the cabin when you raise the panels and almost a negative “G” sensation when lowering the panels – loading, and unloading the wing. Also, with the panels fully extended while airborne, noticeable, and annoying, vibration is felt in the airplane.
In flight, however, they cannot be fully deployed. The airplane has “ground” and “flight spoilers.” While they are the same panels for each, the difference is the number of panels raised. Specifically, the 737-300/400/500 has 10 spoiler panels, labeled zero to ten and starting from the furthest outboard on the left wing. Panels 2,3,6,7 are termed “Flight” spoilers. Once on the ground, with wheel spin-up and compression of the right main landing gear strut, all panels can then be raised, with panels 0,1, 8 and 9 lifting approximately 45 degrees vs. 30 degrees for the other panels.
The “’auto’ speedbrake” can work by either of two methods: 1) Speed handle in the “armed” position (as described above). 2) Leaving the speedbrake handle down and raising the reverser piggyback handles. Personally, I like the latter method better. In “auto” mode the panels come up rather quickly and can give the impression of a firmer landing. By deploying the speedbrakes via method 2, the struts are more fully compressed – relative to method 1 – and tend give a smoother feel to the landing.
Now, aren't ya' glad ya' asked!

For editing .air files, check out AirEd and (my preference)
Aircraft Airfile Manager.

YaYa , I'm wiser now !
Thanks to you all,
