EMB-120 APU electrical load
On the EMB-120 we need to have the load on the APU below 150 amps to start the engines. About 85-90% of the time, the load is already below 150A without having to shut off extra equipment (gasper, recirc fans, logo light etc.) Can someone shed some light as to why on some rare occasions without load shedding, (next leg, same aircraft) the load on the APU will be above 150A. My only guess is that it may be a function of temperature. If that is the case, I am curious as to why exactly that happens.
Thanks
