Voltage fluctuation not modelled?

[TeeJay82]

Ive noticed that turning on every system with the battery off, then engage batteries and engines does no damage to the electronics. now since this is a "real" simulator i find it strange that of probably 100times+ starting the chopper this way, nothing bad happens to any of the systems...

 

So then i question myself... is the simulated startup procedure wrong for the DCS series?

 

IRL i hit the batteries and engage the radio, communicate with the tower then turn off the radio and all other electronics during engine startup to prevent voltage fluctuations to the various systems (radio,Gps...) once engine is running stable at idle i switch electronic systems on..

 

now i only fly a 172... So please dont nuke me for asking a picky question :D

I was a flight engineer, and though you should allways preset your switches in the position... "Ready to recieve power" before you apply electrical power, witch normally means; OFF. Normal or Safe...the equipment will not emediately fail or get damaged if the switch is positioned wrongly.

 

It would be dangerous if, for example, you would get a electrical power failure witch is restored emmidiately would damage your equipment. !!

The Electrical System in the Ka-50 still not fully implemented.

All the electrical gauges (voltmeter Amperometer ecc) on the rear wall panel are not working.

ED team has working on a electrical plugin to simulate electrical effects and fluctuations.

Also, you can't expect damages as a rule. Modern electrical systems aren't as dirty anymore and modern electronics are better protected against spikes and surges (not just planes, just look at the protection that is required for suppliers of electronic devices in cars). Quite likely pilots are still being taught to turn off the avionics prior to engine start Just In Case™ and so that they intuitively do it when they find themselves in that vintage Cessna or something.

...to simulate electrical effects and fluctuations.

 

Link? Not that I doubt it persay, would just like to see the source ;)

Oh how right you are. The testing requirements to comply with ASIL B are ... exhaustive. :P:)

I wasn't even aware of the fluctuations when starting engines. Starting from today I'm gonna turn them on with electric systems off just in case ED adds this (and i guess its a good habit to have.)

With some knowledge on the .lua programming and some info like this:

ELECTRICAL LIMITATIONS

BATTERY LIMITATIONS

Maximum battery temperature is 65 °C, as indicated by illumination of LH BAT HOT

or RH BAT HOT warning lights.

Minimum voltage 20 V DC.

a "Realism Patch" can be made, what you think?

but doesnt the KA-50 keep the sensitive electronics off until you put the throttle on the auto position?

[Devrim]

I remember, how many times I tried to drain the batteries, but, no way...

It keeps the ones off that draw too much current for the batteries (or they need higher voltages, i forgot about the bus layout in the Ka-50, does it even have an inverter?).

 

I'm pretty sure that the checklists are written in a way that would not fry the electronics. Besides, what usually fries a circuit is an overvoltage, and any elements that would have a step response that could cause an overvoltage should be properly guarded.

For the generator you are right.

With the Throttles in Idle you have DC from batteries and AC from Batteries + Inverter.

Yoyo stated in that post new electrical model will be available for new developments only.
