Lift Dump Spoilers

[Bert Pieke 7,585]

Now that I've been introduced to this capability.. a question:

 

Can they only be operated, once the wheels have touched down, or can they be "armed"

in some way?

 

I'm sure, in the real aircraft, that it is simple to reach over and pull the lever all the way back,

but in the sim, that is a complicated action, in the middle of controlling the airplane..

 

Alternately, is there a key command for this?

[JRBarrett 3,070]

In the actual aircraft, there is no auto-deployment - the lift dump has to be manually activated by the pilot. It takes a bit of muscle too. Pulling the handle back to the normal flight spoiler detent is easy, but when you pull up on the handle to move it over the gate, you have to lean on it a bit to push it down all the way to full lift dump.

 

As you have probably discovered, it won't activate on the ground using the default FS spoiler keyboard shortcut "/", or using a hardware spoiler lever - both will only drop the airbrake handle to the normal flight spoiler detent and no farther. It only seem possible to do it by grabbing and pulling down on the lever in the VC with the mouse cursor.

 

There may be some way to assign a keyboard or FSUIPC command to activate it, but I have no idea which command might work without info from Carenado.

OK - I've got it figured out...

 

First full flaps (flaps-3)

 

Then run this:

<Gauge Name="DeployLiftDump" Version="1.0">
   <Image Name="iconpanel_background.bmp"/>
      <Mouse>
       <Area Left="0" Top="0" Width="30" Height="30">
        <Cursor Type="Hand" />
        <Click>
            1 (>K:SPOILERS_ON)
            1 (>L:Lever_Spoiler_Dump_850XP, number)        
        </Click>
       </Area>
   </Mouse>
</Gauge>

Bert,

 

Can you please explain this method step by step?

 

Flaps full, handle back, etc.

 

Thanks!

Flaps full, handle back is the correct way to do it..

 

This is code that will pull the handle back for you, via a clickspot which may be easier to reach..

 

Not "real" but maybe convenient.

.... Bert ,  can you make it to be activated by a button on the joystick

or even a keyboard assignment ?

I was thinking the exact same thing.  Bert is this possible?

 

I have the goflight throttle and I've assigned the spolier and I'd like to assign a button to the lift-dump system. I know that with my payware FSUIPC I can configure the controllers for different airplanes, but I have not ventured into this option. I've only managed to set up throttles for Citation V2 and Airbus 320 etc. and that's with the help of the community.

Can anyone verify that pressing F8 (i.e. full flaps) causes the lift dump flaps and spoiler to activate?

F8 key drops the flaps to 45 degrees. You still need to move the speed brake handle. Just touching it with the mouse moves it back and engages spoilers when flaps are at 45 degrees.

 

If I can find a way to use my goflight TQ6 to control the handle, I'd be set.

Ok thanks.. I've borked my gauge code then haha.

 

I'm working on a way to toggle it using key commands but firstly need to figure out why it's not working normally now.

Out of curiousity, does the lift dump have any aerodynamic effect or is it just eye candy?

It's similar to the effect of reverse thrust. Helps slow the plane down when landing in a short field. Just pray when departing.

Excellent!

Using FSUIPC, I'm sure you can write a little LUA routine to execute those two lines of code.

 

Not my specialty though.. :huh:

Is is actually two steps, moving the speed brake handle to the Spoilers setting deploys spoilers, moving it past the Spoilers setting, all the way back, deploys the Lift Dump.  You can do this all in one motion with the mouse.

[lzamm 143]

Cheap 'n' dirty way of using keys is as follows.  Hard-wires it to a key instead of any other action though, which may not be what you want.

  <Keys>
    <On Key="v">
               --- insert code here --
    </On>
  </Keys>

Put this after the </Mouse> in Bert's code or instead of the entire <Mouse> ... </Mouse> block.  You can of course assign any key instead of "v", or use a key code which lets you use control/shifted keys.

I am able to activate the spoilers with the "/" key.  I may be wrong, not familiar with the "Lift Dump" term.  In fact, this may be the air brakes that is activated, however the spoilers on the wings lift up when I press this key.
