What status message indicates the fuel service panel is switched on?

  1. FUEL SERVICE ACTIVE

  2. AUTO XFLOW INHIBIT

  3. FUEL PANEL ON

  4. AUTO FUEL CHECK

The correct answer is: AUTO XFLOW INHIBIT

The status message that indicates the fuel service panel is switched on is "FUEL SERVICE ACTIVE." This message informs the flight crew that the fueling system is engaged and operational, allowing for fuel to be managed properly during ground operations. When "FUEL SERVICE ACTIVE" is displayed, it assures the crew that the fuel service panel is functioning as intended, which is essential for effective refueling and fuel management procedures. Understanding this terminology is crucial for operating the aircraft safely, particularly in pre-flight checks and ground operations. While "AUTO XFLOW INHIBIT" refers to the inhibition of automatic crossflow of fuel between tanks and "AUTO FUEL CHECK" relates to the automated checks of fuel quantities and system status, these do not directly relate to the activation of the fuel service panel itself. Hence, they are not the correct indicators for verifying that the fuel service panel is operational.
