When signaling for hot brakes, who needs to be informed?

The correct response is that both the maintenance team and pilot need to be informed when signaling for hot brakes. This is crucial because the pilot must be aware of the aircraft's status to make informed decisions about taxiing or taking off, and the maintenance team needs to prepare for potential issues with the brakes and manage any overheating problems effectively. The maintenance personnel may need to take immediate action to assess the brakes and ensure the safety of the aircraft and crew.

Informing just the pilot would leave critical ground personnel uninformed, who play a key role in ensuring the aircraft is safe for ground operations. Likewise, alerting only the ground crew without involving the pilot would not provide the necessary situational awareness for the pilot, who must be cognizant of the potential risks and limitations posed by hot brakes during operations. Thus, both the pilot and maintenance team must be notified to ensure comprehensive safety measures are in place.
