A community mod for the Cessna 208B Grand Caravan EX, which aims to fix many of the issues present in the stock version. Feel free to contribute to this mod! Create an issue or fork and create a pull request!
Disscution about this mod, takes place in the official forum

The mod isn't working? This is usually due to a conflict with another mod in the community folder. The best thing is to remove all other mods and then add them one by one to see what causes the conflict. If you think that you found the legitimate bugor someting what is missing, please describe and submit it at
With the exact reproduction scenario. Saying that feature A does not work usually is not enough to reproduce and fix the issue. 


Based on Sim version (SU8)

Engine and Flight Model
- Corrected Different Values according to POH
- Reverse thrust is strengthened and has a noticeable effect on the plane
- 4 minutes of engine overstress (operating above max torque limit) cause CAS message about metal chips in the oil and increase probability of the engine failure.
The average time of engine failure after metal chips appearance is 100 minutes. The event is random so you may not experience engine failure if you are gentle with the throttle.
If the engine is kept overstressed the probability of the engine failure increases. Each second of keeping the engine above the torque limit decreases the expected engine failure time by 8 seconds.  
You can disable/enable engine failures in the MSFS Assistance Options.

Ground Handling
- More control while taxiing.
- Tighter turning circle.

Electric System
- Electric system of Cessna has been modified to reflect the real aircraft configuration. The battery is connected to an always-hot battery bus. The Master Battery Switch disconnects the battery bus from the main power distribution bus of the aircraft.
- Interior cabin lights are connected directly to the battery bus and are powered independently of the master battery switch position. A pilot can switch on the cabin lights and there should be enough ambient light in the cockpit to operate without a torch.
- Cessna is equipped with a combined started-generator unit. The unit works in starter mode if the engine is below 46% Ng, and in generator mode for Ng above 46%. The generator is connected to the power distribution bus of the aircraft through a contactor. The gen switch allows disconnecting the generator's contactor if required by emergency procedure or to check the operation of the standby alternator during the runup.
- Startup switch allows initiation of the engine startup procedure. Start switch operates only if the engine is below 46% Ng, if the engine operates above 46% starter switch does not interact with any aircraft systems. Putting it to start position powers engine igniters, disconnects the generator contractor, and powers the engine starter. The starter is disabled automatically when the engine reaches 46% Ng. After reaching stable engine operation pilot can put the starter switch to the off position. It disables the ignition system and connects the generator contractor.
- Starter is one of the most power-demanding components on the aircraft. The battery provides the power to start the engine in most realistic scenarios. The current drawn by the starter depends on the external temperature. For temperatures below -20C the starter takes 3500W while above 20C the consumption drops to 2500W. The minimum voltage required to run the starter is 24V.
- The Mod improves the battery, generator, and stand-by alternator current indications on PFD/MFD. The negative value of the battery current indicates that the battery is discharging. Positive battery current means the battery is charging. The charging current is dependent on the battery current capacity. The indicated charging current decreases to zero with the battery reaching full capacity. However, for simplicity, the charging time is not adequate and is usually much shorter.
- All knobs used to regulate the light intensity also impact the light current consumption. The dimmer the light the less current is drawn from the battery or generators.

Anti Ice System
- Anti Ice system has been extended. The Cessna simulates the existence of the fluid-based anti-ice system which is distributed over an aircraft body to prevent or minimize ice formation.
- The tank for anti-ice fluid can hold 20.8 gallons of the liquid and its level can be monitored on PFD/MFD below other engine parameters
- Anti ice system can be put to normal, high, and max anti-ice mode which gradually increases the amount of anti-ice fluid distribution. The first switch allows putting the system into Normal or High mode. Max flow can be enabled by a spring-loaded momentary switch. It works for 120 seconds and then the system returns to either normal or high mode. Similarly, the Windshield switch allows to enables the distribution of anti-ice fluid on the front glass. Unlike in a real airplane, the windshield anti-ice system works for 120 seconds when triggered.
- In the norm and high anti-ice mode the anti-ice fluid pumps work in cycles of being 10 seconds on followed by 10 seconds off. In high icing conditions, putting the anti-ice system does not affect the aircraft. It is to simulate the need of switching the icing to high mode. The high icing condition area has been presested below on the chart as gray area. In the Max flow mode, the system operates continuously consuming most anti-ice fluid per minute.
- In case of failure of the primary system the backup switch allows to use of a backup pump. If the backup switch is turned on the two primary anti-ice switches do not affect the aircraft. The system works in the high mode with the additional distribution of fluid on the windshield.
- because of the simulator limitation antiice system cannot work only using electriv power. Antiice system will work only when the engine is running.
See also:
- In high icing condition stall sensor can become inoperational if not heated. After 5 minutes of ice accumulation the stall sensor either silently stops operating or become permanently triggered. The way it fails is random each time. After failure the only way of recovery is to eanble stall sensor heater. Melting down the ice does not happen immediatly, it takes between 60 - 120 second for the stall sensor to become operational again depending on the amount of ice accumulated on the sensor.

Systems & Avionics
- Works with Vanilla, WT G1000 and WT G1000 NXi Avionics
- Added CAS annunciations, Systems Page, improved engine readouts, fuel indication
- Cruize torque bug does not longer disappear for RPMS slightly above 1900
- Reversionary Mode
- Yaw Damper Working
- Autopilot and instrument fixes.
- More accurate start up.
- Additional Voice Alerts.
- Changed the electric bus configuration to comply with POH
- Generator/Alternator characteristic has been corrected
- Generator trip and reset button works

- Improved lighting (Thanks to Uwa!)
- Improved textures.
- Added some inoperative Switches
- Fixed Cabin lights

I am having an issue when it installed, blank Garmin screens. When I take out the improvement mod the default has working screens, hopefully fixable 😊

not working... =[

The aircraft Is a good improvement adding more a realistic feel to the aircraft, however the throttle is in reverse, so I put my throttle to reverse and it moves forward and vice versa. Another issue is the default camera position is interfering with "msfs pilots. "

Fantastic addon! My favorite turboprop in MSFS. Alas, it appears to have some problems after SU12 (pilot avatar showing in cockpit, flap handle not behaving correctly, yoke won't hide, lighting brightness controls inop). Also appears to have changed primary flight displays. I'll submit a bug report over at Github.

Throttle not working with Brovo. Puts it in reverse

So, on the Blacksquare C208 I have to pull the Fuel Flow Breaker to stop the constant, always on, Warning Sound. This only happens with this Mod enabled.

I'm having an Issue in the Blacksquare C208, when this Mod is enabled. It will keep sounding an Alarm that can only be stopped by pulling one of the breakers on the Blacksquare.

I will get to you with more Details

For some reason my TM Airbus throttles dont work with this mod... even my mouse doesnt move the throttles when hovering over them! Switches dont work either? I dont have any other mods for this AC so wondering what could be the issue?

Thanks you very much for the job done. Any chance to merge you mod with black square analogue gauge?

Does this work OK in the Black Square steam gauge version with the TDS GTN750Xi ?

So the only thing necessary is to replace the wav file for the alarm with silence ?

Works perfectly, looks great

and is a great upgrade for the plane.

It is compatible with SU11,

thanks for that

I have a big issue. I tried several configuration of saitek quadrant throttle even according to many tutorials. All the levers throttle, propeller and condition when set at 0, go respectevely directly to reverse feather and cut off. it seems the aircraft do not capture the 0 detent. It is quite impossible to pilot the aircraft. Is there any suggestion to solve this problem? for the rest 5 stars well deserved

This mod will be continued by @Bocian (NewoPL) under following Link:

I would suggest to bring back the throttle to its previous operation, and give us the option to toggle it on the next update like it used to operate in the previous version. Thanks.

Thanks for the update, but this update includes the reverse in my single throttle, in the previous version I used to toggle the reverse with a key press in my keyboard, is there an option to clear this issue in this update?, I liked the way my throttle worked in the passed version of the mod.

Remercié par Magraina

Thank you werry much

When I started in fs2020 this was my favorite plane. I like the STOL flight, but we lost the realism of the reverse.
Now this is my favorite plane again with realistic reverse. Congratulations to your creator, great job.

Anyone else having very dim displays on newest version? Was unable to make any brighter (Was already at 100%). Went back to previous version and displays were normal.

Your updated mod has my throttle working in reverse now in regular Caravan (velocityOne) and it interferes with my Steam Gauge Caravan (loud peeping sound which I can't turn off). I had to remove it.

works perfectly

Foire aux questions

Des questions ? Trouvez votre solution ici.

Why is the engine not starting

Check if the the condintion lever is set to low idle and the fuel valve is open

Fuel Selectors can't be switched on when starting from cold and dark

There is a conflict with a checklist mod for this aircraft (folder name: TK421-checklist-c208-Asobo). Disabled the mod and the fuel selectors work again.

The mod isn't working?

This is usually due to a conflict with another mod in the community folder. The best thing is to remove all other mods and then add them one by one to see what causes the conflict. If you think that you found the legitimate bug please describe and submit it at with the exact reproduction scenario.
