MFA Follow On Practice Test

In fueling operations, you only start transferring fuel once a secure connection is established between the fueling equipment and the aircraft. The green CONTACT MADE light signals that the nozzle or probe has physically and electrically connected to the aircraft’s fueling receptacle, creating a sealed, safe path for fuel flow. That confirmation is what lets you proceed with the transfer. The other indicators aren’t the right cue for starting fuel transfer. A blue READY light suggests the system is prepared, but it doesn’t confirm that the actual connection has been made. An amber DISCONNECT light points to a state where disconnection is possible or in progress, not to the start of transfer. A Bow Wave indicator isn’t about the connection status for fueling. So the green CONTACT MADE light is the best and most direct signal that fuel transfer can proceed.
