During taxiing, who initiates communication to the flight deck?

In an aviation context, communication protocols during taxiing are critical for maintaining safety and operational efficiency. The correct answer is that both No. 1 and No. 2 are responsible for initiating communication to the flight deck during taxiing. This usually involves the first officer (often designated as No. 1) along with the pilot-in-command or captain (No. 2), who work collaboratively to ensure that all necessary information is relayed to the flight crew.

Effective communication is vital, especially during taxiing, when situational awareness is essential for preventing taxiing errors and ensuring the safety of the aircraft and ground operations. Having two designated team members involved in this communication process fosters a redundancy that helps in confirming or cross-checking important information before proceeding.

In operational terms, having multiple crew members initiate this kind of communication allows for a thorough review of the surrounding conditions and for confirming clearance from air traffic control. This collaborative approach enhances the safety protocols of the cockpit crew and supports a clear line of communication, which is essential during the busy and often congested taxi phase at airports.
