Force sensing sensitivity settings
-
Is the RL F-16 sidestick sensitivity settings adjustable?
If not, is the effort range known?
Setting up newly installed fssb r2, have it on the lowest effort setting, as it is not bolted down yet……
Just trying to get the consensus on the effort most use.
thanx

The article that used to be up on here has been taken down for a long time, it had a graph of the pounds used range in the real one. I’ve read lots and haven’t heard of the real stick being adjustable like that. I’ve found these graphs on page 3 for pitch and roll. http://www.f-16.net/forum/viewtopic.php?f=23&t=212&sid=9bcc375d770f61fa1553636c85fb219c&start=30 They look like what I remember, 16 pounds for roll but I remember pitch up was around 21. Maybe they are different for different blocks.

An interesting thought. I thought positive pitch was at 25 lbs, negative at -16 lbs, and 18 lbs for roll. Cant find the article now though…
Stick
Refer to Figure 1-59. The stick is a force-sensing unit which contains transducers in both pitch and roll axes, moves approximately 114 inch in both axes, and is rotated slightly cw.
Maximum noseup and nosedown pitch commands are generated by 25 and 16 pounds of input, respectively.
Roll commands are generated by a maximum of 17 pounds in cruise gains and by 12 pounds in takeoff and landing gains.
When using the switches/buttons on the stick, inadvertent inputs to the FLCS are possible. -

thank you for the link

I seem to recall reading the SSC itself being cal’d or capable to a max input of 25 lbf all around but then limited in each axis by the FCLS software…but I can’t recall where I got that idea. Maybe from someone that put a real SSC in is pit?
And no - the RL stick is not adjustable for/by aircrew. I’m sure a maintainer can calibrate or op-check it for nominal value, though.
-
Its limited as to what outputs it permits. Im not sure if those limited outputs are still fixed per force, or if they are rescaled against the existing force axis. Either way could make sense, though I would lean towards assuming rescaling, for the effective change in sensitivity it would create.
Its all around that page in the dash, anyway… 1-137. Have a read.

+1. I should think the SCC has a spec it must meet and be maintained to, and the FLCS (sp?) does the rest.
-
The stick is 25 lbs nose up and 16 lbs nose down. For roll it’s 17 lbs in cruise gains and 12 lbs in takeoff & landing gains.

Which again, sounds like the FLCS and not the raw SSC itself…
Once upon a time there was a project over on VP to construct a replica SSC, part for part…which has mostly been taken down, for one reason or another. Or lost in a server move…but I’ll see if there;s any usable info left in the thread.

Correct. You can use 100 lbs if you want but you’re only going to max perform the jet with 25 of those 100 lbs. When new guys come back from a BFM sortie they will sometimes have sore arms because they’re putting so much force into moving the stick thinking they will get better performance out of the jet. The FLCS is excellent at limiting you and keeping it in a flying state.

That’s what I thought…
One of the guys over on VP just got finished sorting a bug in his real SSC - there was some sort of short inside it that was causing his Caution panel to ghost a keystroke. Took him some time to find it, but now more than one guy with a real SSC in his pit is going back and checking.

Guys, I just ran across this thread…I have a real SSC in my pit from the C model and guess what? If I calibrate it in the Foxy viewer so that the cursor just hits the outside edges of the grid, it turns out to be exactly the specs posted above by Fox3TwoShip. I used a digital scale good to 50lbs. and accurate to .001 oz.

Nigel,
When you say that you have a real SSC, you mean bother the stick grip and the sensor unit box it plugs into, yes?
How in the Sam Hill did you figure out the pinout for the sensor box?
And do you have a schematic for the grip?
Which grip or block type do you have?I have two sets of real F16 stick and TQS grips, one stick grip has only one hat (F16-A?) and the other two (block30?).

…if you spend time poking around VP you’ll find many folks that somehow find many real F-16 parts for their sim projects - I forget just how many have real, working SCCs, but there are a few and some good info on them there.
I have a lot more real parts than I thought I would use when I started my own project; my prize so far being a real F-16 primary ADI. That with the help of a number of kind souls I’m working on getting working.
