C208B Grand Caravan EX Mods General

Enjoying this mod. I did notice that Working Title put out a version 0.3.4 of the G1000 vs. the 0.3.3 you include in your release. Given what appears to be pretty big changes from 0.3.2 can I still just drop in Magraina’s fix? Is the fix still necessary?

Alright, well adjusting the pitch ranges does correct the issue.

Not sure if you have the supplement but the real plane’s prop specs are here:

Good find, I think the pitch figures are based on the Hartzell 3 blade, have you tried adjusting the on ground beta and reverse to match? Would be interesting to see what effect it has.

I have, and it works fine. Though I don’t have flying experience in a Van. PilotTrev would be our only accurate source of info on realism.

I’ve changed…
propeller_diameter = 8.5
beta_max = 88
beta_min = 17.2
beta_feather = 88
minimum_on_ground_beta = 17.2
minimum_reverse_beta = -14

Not much of a noticeable performance difference outside of the reverse thrust being much stronger and the throttle response acting predictably.

The POH/AFM and Prop Supplement are in here: https://github.com/SheepCreativeSoftware/msfs2020-C208-Improvment-Mod/issues/14

By the way, the lighting fix you mentioned seems to work fine.

Hi everyone, I finally got around to putting the mod up on github, you can find it here:

https://github.com/dgtlanlg/C208B-mod/tree/c208b-dev

It’s compatible with the most recent Working Tile G1000 v0.3.4

I took the opportunity to update the propeller specs as discussed above and the led backlighting should be working again.
I’ve also bundled the texture fixes for the GMC710/compass into the main mod, so you can delete the old standalone version if you have it.

@TrentKama Thanks Trent, I have the POH but not the sup. prop_reverse_max_vel may need to be adjusted as well.

Thanks. Flew this tonight… worked great.

Is this true to the real bird… the top 1/4 of my throttle lever (Saitek) has my torque(?) (top gauge on MDU) in the red zone. I assume I shouldn’t be flying with it in the red, but then why offer all that extra throttle travel that’s only damaging the engine? What should I be doing?

Reduce the throttle when you hit red?

According to POH, there is a torque limiter. A mechanical device that prevents engine overtorques. It limits the torque to max 2500 FT-LB. I asked recently a pilot, who dropped in with a C208 at my airport, if we can apply full throttle at TO and he sad yes. So, maybe a RW pilot can help here, to clarify how a real C208 is behaving. All I know is that is very annoying and if someone knows where to turn that red light off, please share : - )

I think I tried limiting the torque before and with how flawed the general turbine logic in this sim is right now it just absolutely neutered the airplane. Might try it again to recheck.

@CargoGuy the torque limit is 2500FT-LBs(this limiter is not set correctly in the sim)but the maximum allowed is 2397FT-LB which is why that warning goes off at full throttle. Torque ‘limit’ vs ‘limiter’. :slight_smile:

Setting max_torque_protection = 103.7 does force the Torque to reduce back to <2500FT-LB at full throttle. It takes a second to kick in. This was based off the Maximum Ng allowed in the AFM(103.7%).

Not sure if I’ve seen anyone else report this, but the mod does initially break the C208B in OnAir until max_gross_weight is dropped to 8807 from 8842 and fuel tank capacities are put back to 165 gal per tank to mirror the stock Asobo ac.

Had that problem last night but worked it out. Posted the fix on OnAir forums for others.

Another potential change for the mod…stall warning type.

systems.cfg
[STALL_WARNING]
type = 1 ; 0=Piston, 1=Jet, 2=None, 3=Helo-Turbine, 4=Rocket, 5=Turboprop
stick_shaker = 0

Not sure how ‘type’ effects the sound played; there are piston planes in the sim using 0, 1, and even 2. But the 208’s is a fairly standard vane-type squawker and the ‘Jet’ type produces this.

EDIT: I’ve also been testing the landing distance performance. toe_brakes_scale = 0.6 seems pretty close to AFM values. I’ve also changed max_torque_protection = 104.2 to get a ~2500FT-LB torque limit.

You can test out my tweaks here: https://drive.google.com/file/d/1TT8-n0kKAjyQOxzK3ZALk9hcUx-xXh7J/view (this also includes the latest G1000 mod with the custom annunciations.)

Pretty cool, thanks for the torque limiter and landing distance improvements!

I noticed a weird bug with the dimming of the G1000 in the Caravan, been happening for a while but had forgotten about it and I still see it with 1.12.13.0 and @TrentKama 's mod :

  • if I adjust the brightness right away when starting the flight, everything works fine as intended, the G1000 screens will go brighter or darker when I adjust them, until the end of the flight
  • if I wait and try to do it later (after taxiing or after taking off for instance), the avionics dimmer will turn but brightness won’t change, until the end of the flight

Do you guys have the same issue? I haven’t found a topic about this specific thing but maybe I missed something…

EDIT : happens when I start from the runway with engine running and systems on, not sure if it does the same starting cold and dark

Yeah it’s an odd one, you can still dim the displays by pressing the ‘Menu’ button on the PFD and adjusting the PFD/MFD backlight percentage there.

Hey @TrentKama, you’re more than welcome to have direct access to that repo on github if you’d like.

@TrentKama Thanks for the useful tip/workaround, very helpful!

Maybe? I don’t know my way around Github and my ‘developer’ experience starts and ends at changing values here and there. I can’t seem to post Issues on your fork, though. That might be a easier way to pass on potential changes to you than them getting lost in the posts here.

Was the flight director intentionally disabled? I noticed it wont engage anymore.
