Final answer:
The FIRE EXTGH READY/DISCH light does not stay depressed like FIRE lights; their designs provide clear status feedback to pilots without potentially confusing physical latching.
Step-by-step explanation:
The correct answer is False. In aircraft systems, the FIRE EXTGH READY/DISCH light does not latch into a depressed position like the FIRE lights do. The design of the cockpit controls in an airplane follows strict ergonomic and safety standards to avoid confusion in emergency situations. Fire extinguishing controls are designed to provide clear feedback to the pilot regarding their status. When an extinguisher is discharged, the related light would typically illuminate to indicate the discharge status but would not physically latch in a depressed position.
When pressed, the FIRE EXTGH READY/DISCH light does latch into a depressed position similar to the FIRE lights.
On an aircraft, the FIRE EXTGH READY/DISCH light indicates the status of the fire extinguishing system in the engine. When the light is pressed, it locks into a depressed position to show that the fire extinguishing system is ready to be discharged.
This latching mechanism ensures that the light remains illuminated even after the button is released, until the fire extinguishing system is discharged or the system is reset by appropriate procedures.
