Hello
I have a question regarding starting the APU on the 737 NG aircraft. Here are the conditions (aircraft is on the ground):
No ground power available, no engines running, fully charged batteries (28v).
1. If one sets the DC meter to read "BAT", what would the voltage read before an APU start.
2. What voltage would the DC meter position "BAT" read during an APU start.
3. Is there a noticeable dimming of any lights that are illuminated during the start?
What I am trying to understand is the voltage sag during APU start.
Thank's again to everyone for their help with prior questions.
