Hello all,
I´m trying to follow the different procedures for engine restart in flight. Always starting the procedure with Engine off and low RPM:
- Windmilling: THR idle, Airspeed 450km/h and above 15% rpm, then press ENGINE P/B. It works! (sometimes I need to push more than one time the ENGINE P/B)
-APU Start assisted: THR stop, Press Turbo (inside APU envelope, 260 to 350 km/h and below 6000ft) but TURBO light is switching off or flashing. Sometimes I get a fixed light, but when I try to start, APU switched off. I`m observing that this has a high demand of the electric system (Amperes and Volts are oscillating when APU is starting and switching off). This is not always, but like 70% of times. Why? (I try to give 30sec. between each APU start).
Thank you for helping!
