The POH recommends using an external power unit (EPU) for engine starts when the ambient air temp is less than 0°F / -18°C to save wear on the battery. I’m sure there are some Caravan operators that use an EPU for engine starts outside of that guidance… However, we do not. But, we do use external power quite often for running the avionics and other equipment on the ground. It’s typically “just” the 28V StartPac plug-in power supply (like the pic that Sling380 posted). That type won’t do engine starts though.
If one does use an EPU/GPU for engine starts, it needs to have >800 amp output capability. So one would likely need a larger, stand-alone ground power unit – I’ve been plugged into the trailer type of diesel-powered GPUs from TronAir/Guinault/TLD before but personally haven’t been hooked up to a truck-mounted GPU (though I think those exist).
Hi! Your mod is awesome! Because of it, C208 is one of my favorite aircraft in MSFS.
The only issue is with the Torque gauge. When the prop is above 1800rpm, the toque green line becomes zero, which causes an overtorque indication regardless of the torque settings.
As soon as I reduce the rpm, let’s say, for 1799, the torque green line comes back again and the red overtorque indication extinguishes.
The dynamic red line becomes active only if you’re over 1800rpm.
Which seem to be right.
Dynamic red line and torque bug stay on zero if they active.
This seems for my that the NXi does not executed or failed on execute the linear function behind and stays on zero.
The function from our side does not have a output value to zero.
So it depends on the NXi, I think.
Which version of the game, this mod and the NXi do you have installed?
Are there any other mod which change something with the g1000 or the C208?
I made a few improvements which i submitted to the main mod release. Magraina is looking at it. For anyone who is interested to take a look and test it can be downloaded directly from HERE
Main changes:
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 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 enigne failure time by 8 second. You can disable/enable engine failures in the MSFS Assistance Options.
sound warning when the engine damaging ITT/overtorque occurs.
reverse thrust has noticable effect on the airplane.
a number of additional levers can be moved now, but they still do not have effect on the model.
generator trip and reset button enables tripping the main generator.
interior lamps do not require master battery switch to work.
took about 14min for engine to get complete failures, at a bit over 2400lbs torque
ITT stayed normal, below 700c IIRC
is it safe to get torque above the blue bug, but below the red line?
also, I guess it a sim limitation, but as soon as the engine died, ITT dropped to external temp (-17)
would it be possible that it stays somewhat warm?
I was experimenting with ITT a little bit. ITT is more difficult to control. My guess is that it will require implementing ITT model independent of the sim. BTW. Is it possible to get engine hot start right now ? I could not do it.
@fbachian I updated the build. you can try it. the torque should not be jumping right now at 1800 RPMs. However, the max torque still changes with temperature and altitude. I see that it is more or less as described in POH.
