Selecting the AFT CARGO SMOKE PUSH button activates which of the following?

Selecting the AFT CARGO SMOKE PUSH button activates both the alarm systems and signals the pilots. When this button is pushed, it indicates the presence of smoke in the aft cargo compartment, which triggers alarms to alert the crew. This system is designed to ensure that any potential fire is detected quickly, and the crew is informed immediately so they can take appropriate action.

This dual activation enhances safety by ensuring that the pilots are aware of the situation in the cargo area while also activating relevant alarm systems that may include visual and auditory alerts within the cockpit and cabin. Taking decisive action when smoke is detected is critical to maintaining the safety of the aircraft, making the functionality of the AFT CARGO SMOKE PUSH button an essential aspect of the aircraft's fire detection and suppression systems.
