• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

FSXA A:FLAP DAMAGE BY SPEED inop. Any idea?

Hello there!

Playing with FSCaptain has brought my attention to the fact that [flaps] sections of an aircraft.cfg includes two parameters that define flap failures : flap damaging-speed and flap blownout speed.
If the KIAS exceeds these values, two A:vars are supposed to be set to 1 : A:FLAP DAMAGE BY SPEED and A:FLAP SPEED EXCEEDED.
FSCaptain reads these 2 A:vars and inflicts harsh punishment to misbehaving pilots... :mischievo

But I can't have them to work in my sim . I have tested default, freeware or payware planes (aircraft.cfg config is OK), not a single flap fails...
My settings in realism tab are :

Flight model : everyting maxed out.
Failures and damages :
Ignore etc : not kicked
Detect etc : kicked
Tension leads to failures : kicked
Possibilies of collision with another airplane: kicked
Engines :
Stress damages engine : kicked, two other unkicked
Special effects :
G effects : kicked.

Having this failure to operate on its own will help me saving time with my damage mod, so I hope someone has a clue about all this.

Thanks for reading anyway!

Well, further tests report here.

Well I did manage to jam the flaps on the F1's BN-2 Islander with the following flaps section in aircraft.cfg :

[flaps.0] //Visual
type = 1
span-outboard = 0.40
extending-time = 12
damaging-speed = 45 // initialement 115
blowout-speed = 60 // initialement 130
lift_scalar = 0.00
drag_scalar = 0.00
pitch_scalar= 0.00
flaps-position.0 = 0
flaps-position.1 = 55 //, 114
flaps-position.2 = 100 //, 89

[flaps.1] //Lift
type = 1
span-outboard = 0.40
extending-time = 12
damaging-speed = 45 // initialement 115
blowout-speed = 60 // initialement 130
lift_scalar = 1.00
drag_scalar = 0.00
pitch_scalar= 0.00
flaps-position.0 = 0
flaps-position.1 = 30
flaps-position.2 = 56

[flaps.2] //Drag
type = 1
span-outboard = 0.40
extending-time = 12
damaging-speed = 45 // initialement 115
blowout-speed = 60 // initialement 130
lift_scalar = 0.00
drag_scalar = 1.25 //1.00
pitch_scalar= 0.00
flaps-position.0 = 0
flaps-position.1 = 15
flaps-position.2 = 56

[flaps.3] //Pitch
type = 1
span-outboard = 0.40
extending-time = 12
damaging-speed = 45 // initialement 115
blowout-speed = 60 // initialement 130
lift_scalar = 0.00
drag_scalar = 0.00
pitch_scalar= 1.20 //1.00
flaps-position.0 = 0
flaps-position.1 = 30
flaps-position.2 = 56

But the weirdest of all this is that the (A:FLAP DAMAGE BY SPEED, bool) and (A:FLAP SPEED EXCEEDED, bool) vars remain at 0. They do not toggle to 1 after/when the flaps fail.
I monitor this with a simple gauge that light up a bmp if the var toggles (with a confirmation with landing lights):

<Element>
<Position X="0" Y="0"/>

<Select>
<Value> (A:FLAP DAMAGE BY SPEED, bool) (A:LIGHT LANDING, bool) OR </Value>
<!-- <Value> (A:GENERAL ENG ANTI ICE POSITION:1, bool) </Value> -->
<Case Value="1">
<Image Name="Eng1DeiceOn.bmp" Bright="Yes" />
</Case>
<Case Value="0">
<Image Name="StructDeiceOff.bmp" Bright="Yes" />
</Case>
</Select>
</Element>

And I am affirmative, the flaps fail but the A:Var do not toggle. I really am at a loss.
Does any FS wizzard have a hint about about what's going on here?
 
Must be a FSX bug then.

Just jam the flaps manually by countering any flap lever inputs.
 
Hello Heretic,

I don't know what I have changed, but now the flap failures work in both FSX and FSCaptain. Another mystery solved by a mystery trick. Thx anyway.
 
That's a relief, yet mildly unsettling since there's no logical fix involved. :eek:
 
The P3D SDK has an explanation for FLAP DAMAGE BY SPEED. True if flaps are damaged by excessive speed.
FLAP SPEED EXCEEDED is True if safe SPEED limit for flaps exceeded.
Note this is the only reference to FLAP singular all other references are to FLAPS plural.
The FSXA SDK explanation is SELF EXPLANATORY. Like many other vague variables.

In the config file there are definitions for the SPEED that are a bit confusing.
Damaging-Speed SPEED at which the flaps begin to accrue damage. The example given is 152 IAS for the Baron.
Blowout-Speed SPEED at which the flaps depart the aircraft. The example is 300 for the Mooney.

So which is which? I suppose that doing 153 IAS with flaps down in a Baron would toggle FLAP DAMAGE BY SPEED, but what would you do with a plane with multiple speeds for different FLAP settings?

My computer is in the shop, but as soon as I get it back I'll be hard at work doing SPEED dives in the Mooney

If the flaps have different speed limits for multiple flap settings then the variable will toggle back and forth as needed as you move the flaps.
 
Hi!

Thanks for your inputs about this "issue". One explanation that I can imagine is that flap jamming/failure (or A:Var toggling) does not happen at the moment the "flap damaging speed" is exceeded, but one has to overspeed over a certain period of time to jam the flaps indeed. And that I didn't fly too fast for long enough in my first tests.
My best try would be to monitor the variables with Linda or with a dedicated gauge...
