How to fix low volts/ oil pressure on bonanza g36?

[Glenn]

I've just started going through the Bush trips. Got to Norway and im a couple of airports in, but on the current airport, the plane will not start at the runway.

It shows low volts caution and I can see that oil pressure also says low.

When I try to start, the propeller starts to spin with very low rpm, like around 500-600 max, but then stops after about 1 or 2 seconds.

I've tried looking at startup videos on YouTube, but can't see this problem anywhere.

Some posts online say that the engine won't start if it's flooded, so to put mix to low when you start, others say that it always starts with nothing pumped in so you need to turn on the fuel pump again.

I haven't found anything addressing a "low volts" caution though. Does this mean that the battery is dead or something? How do you even check that on a simulator?

Any ideas?

Sounds like you stressed the Engine into Red or left Pumps ON if they drained Battery. Not flown it in ages. On other Planes you only need check FUEL TANK=OPEN; BATTERY=ON; ALTERNATORS =ON; MAGNETOS=ON; FUEL PUMPS=ON; FULL MIXTURE; 1" THROTTLE (1/2" on TWINS); HOLD START UNTIL RUNNING. PUMPS can then go OFF as Centre Tanks (not in Airliners or others with Fuel in Wings).

I even stressed the C414 Right Engine alone enough to cause 1/2 power for that and then it also affected both. On the DA40 & 62 it's easy to kill the Engines by this. Never go into Red even if adjusting Mixture to boost RPM. Add 5% MIX as Coolant rather than solely lower Throttle.

I'm mainly going to focus on this sentence here and suggest that perhaps you do not have any fuel.

I have not flown bush / discovery trips for a long time but there is / was a bit of a problem in that you could not refuel. To do so you had to find an unassigned bind and assign it to something, then you could "cheat" fuel back in to your aricraft.

I don't fly this plane but do still have this installed.

Last updated May 16th so it should be good to go.

Bonanza Hangar

A custom in game panel where you will manage your aircraft. This is a work in progress feature but aims to replicate some of the features found in the A2A aircraft hangar. This is still very much a WIP feature and will evolve over time.
Added functionality to Hangar Module (we now save engine hours, miles flown, and count down to annual and 100hr service per livery) state saving items are shown on the State page (menu link at top)

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.
Tweaked fuel flow as current flow slightly less than book figures (Rpt by @JayDee6281)

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
Fixed missing altitude alert tone @200ft to go
Fixed missing decimal point to manifold pressure gauge
Added SU8 Prop Modelling - This has changed the speeds/fuel flows it may take a little while to dial this in. At the moment the climb fuel flow is slightly lower than book and cruise is about there.
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

Long story short: for whatever reason, having all the electricals on before you start the G36 will overload the battery and you will get low amps. Two things you can do to work around this is 1) as suggested start with higher RPM, so add some throttle right away until the warning goes away - also watch the ammeter. 2) Don't turn on all of your cockpit electricals until you've stabilized the engine. That might go against real world checklists until this gets resolved.

[★Macman★]

Does it have any FUEL TANK Valve to open anywhere? Does using the START BIND work as a work around?

[Maki Nishikino]

If you run into the problem again please post a video, I will be happy to try and help you.

Normally you turn avionics on AFTER the engine has started and stabilized and you turn avionics off before you drop the mixture or shut down the engine whichever applies. This is so any fluctuations in engine RPM won't send weird voltage spikes through the system into the super expensive GPS equipment and autopilot. Note that not all aircraft are the same. Check the real world POH for the startup checklist for that aircraft.

AFAIK FS 2020 engine simulation is not detailed enough to simulate a flooded engine. The engine simulation in the sim is quite basic. For instance in the 172 you are supposed to push the throttle in about 1/4 inch and crank until you hear it try to fire and then add full mixture. In FS 2020 it will never try to fire with the mixture set to idle / cutoff.

Also priming the engines seem to have little to no effect.

One suggestion would be to remove the G36 improvement project from your community folder and then start the bush trip at that location again and see if the problem still remains. You could also try starting a new flight at that airport with the G36 (with the improvement project still installed) and see if you can start the engine. Another thing would be to check your preferences and either reset any failures or turn failures off if enabled and see what happens.

Also, in the aircraft selection the Beechcraft Bonanza G36 Improvement project is a separate listing from the default Asobo Beechcraft Bonanza G36. You could try selecting the default version if you were having the issue with the improvement project one. Depending on the number of hours you have flying the G36 you may need to go into the improvement project hangar and do the inspection on the aircraft.

Thanks for the suggestion. It's the regular version im using, as I don't have anything installed in the community folder, also I can choose the aircraft in the Bush trips.

Touch wood, just starting the trip from the 1st leg has fixed the issue though.

So now it will be interesting to see if the same issue develops at the same place in the Bush trips as before.

Might be a bug with the bush trip. I didn't tried that one, only flying my own FPs. Quite often with G36, its one of my favorites. I have probably about 100 hours with G36 on max realism settings and never seen something like what you describe. Im starting up the engine just following the default checklist. Also using default liveries and no any tuning mods for the G36.

[Twelvefield]

The G36 is a lot of fun to fly from the Asobo fleet. It lets you tinker with landing gear and prop pitch, making it the most complex single engine GA aircraft in the game. The C152 and 172 recently had added a better flight model, so right now that has my attention. The Beechcraft King Air also has the improved flight model, but I don't fly multi-engine planes much or really at all.

There's no way I could get behind the yoke of a real G36, so I only know about it through sim. I definitely see the undervolt, and as I mentioned I just make sure I don't turn on all the electricals until the engine RPM is stable. If the battery is dead, the prop won't move at all and all of your instruments will be dark. You can kill the battery by leaving the starter on, just like you would harm your car if you kept pushing the key into the ignition position after you've started the engine. Make sure the ignition is in the correct position.

If the aircraft is starved of fuel, the starter motor will move the prop but as soon as you release the starter the prop will die. So maybe you ran out of fuel, there's a small possibility you have the ignition in the wrong position or you cut off the fuel, but my guess is that you found a bug. The bush trips can sometimes encounter them.

Most aircraft POH have a suggested RPM for various ramp, hold short and other operations. If you fall below this RPM you might get low voltage situations, rough running, etc. Cessna recommends 1000 RPM for the Cessna 172SP so it runs the smoothest and causes less strain on the engine while also providing enough charge to the system. This means at hold short lines, on the ramp or anywhere the aircraft is not moving or the brakes are being held. And you can tell in the aircraft that the engine does not like running under 1000 RPM. It is very rough. So it is pretty much instinct to keep it at 1000 RPM in these situations.

I would check the real world POH. My bet is they also recommend a specific RPM and likely due to what you are seeing. The charging system might not be adequate enough below a certain RPM when the engine is not under load.
