What uses information from the T2 probe
FADEC
Overhead panel: Available light, what’s that mean?
Correct Voltage, Phase, and Frequency. 115 VAC, 3 Phase, 400Hz, 40 Kva
What does 3 Phase mean
Common method of alternating current (AC) generation, transmission, and distribution. 3x alternating currents of same frequency. The delay between frequencies has effect of giving constant power transfer. High demand aircraft system use all three phases for more power than single phase can provide.
