[NO BUG] Starter - Generator

[AH_Sid]

It's stated in a couple of locations in the manual that the generator output is not available until engine rpm is approximately 45%.

 

 

 

In the current public build ( V1.5.2.48162.126), the generator is coming online incorrectly at 35%.

Re-reading that, it does say "rated generator output is not available until engine rpm is approximately 45%"

 

So is the generator warning light going out at 35% because the generator is producing some output, just not rated output?

In 2.0 it's always on... or the warning light is broken, or the idle RPM is too high (haven't compared to 1.5.2). Anyway, it generally needs to be looked into.

Yes, this is correct. Rated output is available at 45%, but generator comes online at 35% and light goes off. So, currently it is modelled correct

Thanks cofcorpse, yes that makes sense now.

As mentioned here the aircraft is at IDLE (around 30% RPM), but as stated later in the manual, idle rpm varies with altitude and temperature.

 

 

This increase in idle speed seems to be correctly modelled, for example:

 

Senaki-Kolkhi, Altitude 39 feet, Temp +18°c gives at idle of 30%

 

Beslan, Altitude 1772 feet, Temp +15°c gives at idle of 33%

 

McCarran Intl, Altitude 2051 feet, Temp +21°c gives at idle of 35%

 

Groom Lake, Altitude 4459 feet, Temp +30°c gives at idle of 40%

 

So in 2.0 the idle is likely to always be high enough to have the light out (generator on) because of the altitude, unless you set the temperature extremely low.

That must be the case. I always forget how high above MSL the Nevada facilities actually are. Very nice modeling detail.
