On which ECAM page would you find the APU voltage and frequency information?

• A. ECAM ELEC page
• B. ECAM SYS page
• C. ECAM ENG page
• D. ECAM HYD page

Answer: (A)

Voltage and frequency from the APU are electrical data. The ECAM ELEC page is where the aircraft’s electrical power system is shown—generator status, bus voltages, frequencies, and related parameters. Since the APU’s job is to provide electrical power, its output characteristics belong on the electrical page. Other pages cover different systems—SYS is general systems status, ENG shows engine parameters, and HYD shows hydraulic data—so they don’t display the APU’s voltage and frequency.
