What does the ammeter indicate in relation to the electrical system?

• A. The percentage of fuel remaining
• B. The flow of current to and from the electrical system
• C. The temperature of the alternator
• D. The pressure in the fuel system

Answer: (B)

The ammeter is a crucial instrument in the aircraft's electrical system, providing valuable information about the flow of electrical current. Specifically, it indicates the amount of current flowing into and out of the battery and electrical system. When the ammeter shows a positive reading, it signifies that the alternator is generating more electricity than is being consumed by the electrical loads in the aircraft, allowing the battery to recharge. Conversely, a negative reading indicates that the electrical system is drawing more power than the alternator is producing, which can lead to battery depletion. Understanding how to interpret the ammeter reading is essential for effective management of the aircraft's electrical systems and ensuring that the battery remains adequately charged throughout the flight.
