Final answer:
Pressing the ENG 1(2) FIRE pushbutton on an aircraft's fire panel initiates crucial firefighting and safety measures including fuel shutoff, hydraulic and electrical isolation, and activation of the fire extinguishing system for the affected engine.
Step-by-step explanation:
When the ENG 1(2) FIRE pushbutton is pressed on a fire panel, typically found in the cockpit of an aircraft, it activates a series of safety and firefighting measures related to the corresponding engine. These measures often include:
- Shutting off the fuel supply to the engine to prevent further fuel feeding the fire.
- Deactivating the hydraulic systems associated with the engine to minimize the risks of hydraulic fluid fires.
- Isolating the engine's electrical systems to reduce the risk of electrical fires and to prevent electrical malfunctions.
- Activating the engine fire extinguishing system, which releases fire-suppressant agents to extinguish the fire.
These actions are critical for maintaining safety and protecting the aircraft from further damage in the event of an engine fire.
When the ENG 1(2) FIRE pushbutton is pressed on a fire panel, it initiates a series of actions to respond to an engine fire emergency.
When the ENG 1(2) FIRE pushbutton is pressed on a fire panel, it initiates a series of actions to respond to an engine fire emergency.
First, the fire extinguishing agent is discharged into the affected engine, such as a foam or chemical agent, to suppress the fire. Additionally, the pushbutton triggers various alarms and warning lights to alert the crew of the fire. The engine may be automatically shut down to prevent further damage, and the fire's location is displayed on the fire panel so that the crew can take appropriate action.
