Startup Proceedures, battery last?


Recommended Posts

Posted (edited)

I'll start with saying I've not bought the module yet, but I'm slightly confused after watching videos and reading the Razbam manual as to the order of the start proceedure.

 

Does it strike anyone else as odd that you're starting the engine with the battery off, having the instruments come alive while it's spinning up, and then when spun up turning on the battery and alternators?

 

It feels unusual that there's enough power available from the engine at start up to light a number of instruments, especially when in every other DCS aircraft you have to connect the battery first to get basic systems up and to allow starting. It also suggests the aircraft is never truly 'cold and dark'.

 

Was trying to find the 'proper' manual, but what I can find seems to be behind paywalls currently.

 

Can anyone else shed some light on it?

I think it's because in real life, the aircraft starts with an external power unit. But I could be wrong.

 

Edit : Found this post from Zeus

Hmm, Zeus's post doesn't say at what step the batteries should be connected though, and that it can start from either internal or external power :/

 

If it was from external power, I'd expect some of the instruments to be alive before the engine starts.

In the French version of the flight manual the first thing it mentions should be turned on (Marche) are the BATT, TRN, ALT1 and ALT2.

 

So it does seem odd that that is not mentioned first in the procedure.

I think the battery should be the first think to switch on unless you have GPU, very common on big commercial airport but I don't think that the m2kc can Pe powered up with a GPU ( can't see the GPU switch...) it doesn't have even an APU

What I suggest :

 

Turn the battery on,

Align the INS

when aligned, then you can start the engine, normally when aligning the INS, the aircraft must not be moving even a iota otherwise the alignment must restart, this is however how it's done on commercial aircraft, I don't know about fighters my knowledge being non existent

The M-2000C uses a jet starter in the same way your car uses an engine starter.

 

It can be powered by both external or internal power. The VENT switch selects from which side is the power coming, to which side to vent the starter exhaust gasses.

 

At this moment, star battery first. Later on, when the aircraft gets more complex, other options will be available as well as limitations.

Limitations like you only get 4 tries to start the engine before you drain the battery, one of the reasons why a power cart is preferred but not necessary.

Right now, when you turn the VENT switch, some electronics in the aircraft turn on with battery still disconnected (no GPU). Is it supposed to behave like that?

For the time being yes. That is a debug/test feature we left on until it becomes redundant. It is supposed to mimic the existence of a connected power cart.
