That's great. I was previously on the fence about this mod as was very happy with Rob's work, but if I can now have my cake and eat it, I will!

Enjoy your cake 🙂

HI All

Just a quick note to say that I have pushed out a small update based on user feedback on the speed it takes to foul the plugs. You will need to aggressively lean when on the ground, if you encounter fouling at low RPM’s (<1000) you are at real risk of the engine stalling. It may take us a while to dial these figures in.

NEW! Spark Plug Fouling - if you don’t lean correctly both on the ground and in the air your plugs will encounter spark fouling, losing RPM and engine power. If you leave the plugs fouled the engine will continue to lose power until finally shutting off. After leaning the effect will take a time to work itself out.

I am so so glad that someone has implemented this into an MFS aircraft now! It's a key part of operating carburettored aircraft and I was very sad when Asobo didn't include it as standard within their piston engine simulations. This mod has been my go-to GA bird from day one and it just goes from strength to strength.

Thank you for your kind words!!!

I'd be interested in any feedback regarding the fouling simulation, it is very much a work in progress whilst I pin down the various variables involved.

My engine is quitting after the run up when I do the idle check. The g36 should be able to idle without the engine quitting on the ground if the oil temp is green and the fuel pumps are off right ? The checklist calls for an idle check with mixture full rich. Let me know what you think.

I think your right, I may need to tweak how long it takes to start the fouling, currently it starts to accrue after about a minute and then gets worse on a scalar of time. I may also need to relook at adding a logarithmic scale based on rpm. I have found at idle it kills the engine pretty quickly if there is some fouling. 

I'll have another go after work today.

With a warmed engine it should idle at full rich for a short period without going lumpy or cutting out (they don't die immediately, they run rough briefly as a bit of a warning). There should certainly be enough time to do a brief rich idle check following run-up (the run up should have cleaned the plugs, if it's been a long taxi you might even see some smoke during run up because of this). If you get a significant rpm imbalance or rough running during the mag check, that can be caused by spark plug fouling on that mag circuit.

Leaning on the ground and keeping above 1000 rpm  and they hardly foul as the lead scavenging agents in the fuel (ethylene dibromide?) are activated and oil hopefully being burnt off, so that just leaves potential carbon build-up.

If the engine starts showing signs of fouling (running rough), provided it's not got too bad you can gently accelerate engine RPM and maintain higher RPM for a minute or so, this usually clears it often with a bit of exhaust smoke (I believe the method of action is thermal shock causing deposits to flake away?). If the engine has cut out from plug fouling, then it may be difficult to restart without removing the spark plugs and manually cleaning them. You can get fouling whilst flying too but it's far less common, a prolonged idle descent with the mixture overly rich might cause this.

Note the above is generalisation and not specific to the G36, every engine and individual aircraft differ. Particularly if they've got fine wire spark plugs and fuel injection they'll be far less prone to fouling.

Exactly this is how it’s done in real life and how I was taught though I’ve never flown an io 550

I've tried your beta and the lack of warning is perhaps the most noticeable ommission, it just dies without any rough running beforehand. Also not sure if clearing is simulated yet (I think the notes said not?), but during mag check I was struggling to get it the plugs to clear.

Hi All

I am very pleased to present the MSFS G36 Improvement Project version 0.6.6!

https://flightsim.to/file/21221/bonanza-g36-improvement-project

This is the improvement project for the MSFS default G36. It all started as a simple edit of some configuration files but it has since grown into a fully-fledged modification that improves all aspects of the default G36 and introduces new features. This was made possible with the help of the community consisting of both enthusiasts and G36 pilots (for a list of contributors, see the end of this readme).

We now have a discord channel! https://discord.gg/JVPMYdKx86 or you can continue to use dedicated MSFS forum post https://forums.flightsimulator.com/t/g36-improvement-project/216094 I really value your constructive feedback.

Installation

  1. Download and install the Working Title NXi from the store Marketplace
  2. Download and unzip the folder ‘bonanza-g36-improvement-project’ in to your MSFS Community folder
  3. The Bonanza G36 Improvement Project is now listed as it's own aircraft in the menu rather than overwriting the default aircraft (please see livery note)

PLEASE NOTE - WE HAVE REMOVED THE 'Z' FROM THE FOLDER NAME, ENSURE YOU REMOVE THE OLD VERSION PRIOR TO USING THIS ONE!!

New in this version:

  • NEW! Custom Livery provided by @Crispy136 (Thank you!) You can find more of his liveries here https://flightsim.to/profile/Crispy136/uploads
  • NEW! Added TAWS system test message
  • NEW! Integrated @BufordTX's VR Friendly Prop Mod
  • NEW! Changed environmental controls to read C° rather than F°
  • NEW! Spark Plug Fouling - if you don't lean correctly both on the ground or in the air your plugs will encounter spark fouling, loosing RPM and engine power. Each spark is modelled independently and has its own likelihood to foul; this stays across flights, the spark most likely to foul will foul first followed by the next etc.
  • NEW! Bonanza Hangar; You will manage your aircraft here, check for spark fouling, oil changes and more. This is still very much a WIP feature
  • Reworked Engine performance figures: after more than 30hrs of testing and tweaking, the engine performance figures match the POH as close as we can get them and have been verified by real Bonanza pilots. TAS is within 0.22kts on average across the altitude spectrum and fuel flow within 1g/h.

Fixes

  • Fixed: NXi Engine System Page spacing
  • Fixed: Aircraft getting stuck on the ground. Changed nose height on gear to reflect reference pictures, increased nose gear damping affect, thanks to Synoxys787 for his help and research
  • Fixed: Missing registration and ASI error, thanks to Bert Pieke on Avsim.
  • Fixed: Incorrect circuit for PFD, removed sharing two busses. (@meh1951)
  • Fixed: Increased brightness of taxi & landing lights (@meh1951)
  • Fixed: Missing '=' in the bonanza hangar. (@DA40CGDFQ)

Liveries

We have split out the files from modifying the default Bonanza to becoming its own aircraft. This is so we can complete further 3d model changes, and work on the hangar module and deeper systems modelling. Liveries will need to be amended to reflect this new aircraft to work. More information here https://forums.flightsimulator.com/t/g36-improvement-project/216094/1943

Features:

Flight dynamics/performance

  • Adjusted climb and cruise performance to match the Bonanza G36 POH charts.
  • Adjusted flap and gear drag
  • Slightly reduced pitch effect due to elevator deflection + propwash
  • Slightly increased nosewheel steering angle
  • Added drag due to cowl flaps. This causes a 3-4 kts cruise speed loss.
  • Decreased yaw sensitivity by lowering deflection rate as a function of speed
  • Increased overall stability: less 'twitchy' feeling

Engine & Fuel system

  • Completely overhauled engine parameters: realistic fuel flow, mixture-EGT interaction, engine performance at all pressure altitudes.
  • Simulation of Spark Plugs
  • Simulation of the electric fuel pump
  • More advanced simulation of engine start-up:Cold starts: correct use of the fuel pump, throttle and mixture required depending on engine and ambient temperature
  • Under some conditions, idling the engine too soon after start may cause it to quit.
  • Flooded engine: pumping too much fuel to the engine may cause it to ignite slower or not at all.
  • Flooded engine start procedure (mixture low/cut, throttle halfway) may resolve this.
  • A hot engine running idle with little airflow may quit because the fuel evaporates.

Systems

  • Added new working systems and switches:Airco (has a negative effect on engine performance, you will see a few kts lower cruise speed)
  • Airco and ventilator switches are functioning and part of the electrical system
  • Annunciator test
  • Electrical system overhaul:Completely revised electrical buses: all individual systems hooked up to the correct bus
  • Bus tie logic added
  • Correct voltage indications of BUS2 due to reverse current blocking diodes
  • Correct alternator loads
  • Made all indications smooth, rather than instant jumps to a new value
  • Autopilot tweaksFixed holding the wrong altitude at non-standard atmospheric pressures
  • Max pitch and bank angles adjusted for smoother AP behaviour
  • Added maximum and minimum IAS_ref speeds for FLC mode
  • Adjusted autopilot PIDs
  • Integration with the Working Title NXi mod, with customized ENGINE, LEAN and SYSTEM pages.
  • Completely redone G1000 annunciators: all annunciators of the real G36 were implemented (except for door open warnings)
  • Corrected fuel gauge scale

Textures & effects

  • Including the latest version of Uwajimaya's lighting mod (https://uwajimaya.github.io/FS2020/)
  • Corrected decals (e.g. shoulder hardness -> harness)

Checklists

  • Interactive checklists for every stage of your flight that follow the POH

ATC

  • You are now referenced as Bonanza > Your Callsign in the game ATC

AIRCRAFT PERSISTENCE / STATE SAVING / MAKING THE PLANE 'REAL' (WORK IN PROGRESS)

Your aircraft now remembers how you left it! States are saved for each aircraft livery, so you can multiple 'living' Aircraft. On first flight load of the new 0.6.6, your aircraft is set cold & dark with 64 gallons of fuel. The aircraft now saves the following tank levels, switches and levers every 5 seconds:

  • Left & Right Fuel Tank Level, Battery 1 & 2 switch, Alternator 1 & 2 Switch, Parking Brake lever, Avionics Switch, Airconditioning Switch, Blower switch, Vent Blower switch, Aux Fuel Pump Switch, Magneto Switch, Pitot Heat Switch, Prop De-Ice Switch, Strobe Switch, Beacon Switch, Nav Light Switch, Flood Light Switch, Panel Light Switch, Taxi Light Switch, Landing Light Switch, Fuel Selector , Position, Defrost switch, Throttle Position, Propeller Position, Mixture Position, Cowl Flap Position, Flaps Switch, Flaps Physical Position, Pitch Trim Position, Aileron Trim Position, Floodlight Brightness, Pilot & Passenger Yoke Visibility,

When you next climb into your aircraft you will find it just as you left it!

NOTE: The aircraft state is only loaded if:

  • You are on the ground in a parking spot or
  • You are on the ground somewhere else and your engine is off.
  • This allows the aircraft to load in flight or ready at the end of the runway without messing with the aircraft load. It WILL however, still record switch states and tank levels etc.

I have to say...very impressive stuff. Talk about study level. I'm not even sure what that means, but if this isn't it, I don't know what is.
