What is the voltage of the DA42NG electrical system?
28V DC
How many main electrical systems are there?
Two (left and right)
What provides electrical power during normal operation?
Engine-driven generators
What is the function of the battery?
Provides power for engine start and backup power
Does DA4NG have more than one one battery?
Yes, typically a main battery and essential/emergency battery
What is the purpose of the essential bus?
To supply power to critical systems during failures
What happens if generator fails?
The other generator or battery supplies power
What is load shedding?
Automatic disconnection of non-essential systems to save power
Are the left and right electrical systems normally connected?
They are mostly independent but can support each other
What happens to the battery during normal flight?
It is charged by the generators
What powers the aircraft before engine start?
The battery
Why is redundancy important in the electrical system?
To ensure critical systems keep working if something fails
What kind of current does the system use?
Direct current (DC)
What is the role of generators besides powering systems?
Charging the battery
What happens if both generators fail?
The battery powers essential systems for limited time
