Question: 1 / 1030

Evidence that a fire extinguishing system has been intentionally discharged is indicated by what?

The presence of a red disk.

A visible smoke signal.

The absence of a yellow disk on the side of the fuselage.

When a fire extinguishing system has been intentionally discharged, a red disk will be present to indicate this. This is incorrect because a red disk is typically used to indicate that the fire extinguishing system is non-functional or has already been used, not that it has been intentionally discharged. Option B is incorrect because a visible smoke signal may or may not indicate that the fire extinguishing system has been intentionally discharged, as smoke can also be caused by other factors such as a fire in the cargo hold. Option D is incorrect because an audible alarm may indicate a fire, but it may not necessarily indicate that the fire extinguishing system has been intentionally discharged. The correct indicator for an intentional discharge is the absence of a yellow disk on the side of the fuselage, as this disk is specifically designed to show that the fire extinguishing system has been intentionally discharged.
