The Flight Deck Handset (FDH), also known as the Flight Deck Telephone, is an essential communication device located in the cockpit of the Boeing 777 aircraft. It plays a crucial role in ensuring effective communication between the flight crew members and various ground personnel, including air traffic control (ATC), maintenance teams, and other flight crew members within the aircraft.
The FDH is a handheld device with a corded handset that is connected to the aircraft’s communication system. It allows the flight crew to communicate with different parties involved in the flight operations, enhancing coordination, safety, and efficiency.

The Functions and Features of the Flight Deck Handset (FDH)
The Flight Deck Handset on the Boeing 777 aircraft offers several functions and features designed to facilitate communication during flight. Let’s take a closer look at some of its key functionalities:
1. Two-Way Communication
The FDH facilitates two-way communication between the flight crew and ground personnel. Using the handset, the flight crew can establish contact with air traffic control towers, maintenance personnel, and other relevant parties. This allows them to receive important information, updates, and instructions related to the flight and address any concerns or queries they may have.
Additionally, the FDH allows ground personnel to communicate directly with the flight crew, providing assistance, relevant operational information, or guidance if necessary. This two-way communication enhances situational awareness and enables prompt decision-making based on real-time data and instructions.
2. Call Forwarding and Diversion
The FDH on the Boeing 777 aircraft offers call forwarding and diversion capabilities. This means that if the flight crew is not available to take a call on the FDH, it can be forwarded to another designated crew member or redirected to another communication interface within the aircraft.
Call forwarding and diversion are essential features that ensure uninterrupted communication in case the assigned crew member is busy attending to other critical tasks or if the FDH is temporarily unavailable. It allows for efficient distribution of communication workload and prevents any delays or missed messages.
3. Clear Audio Quality
The Flight Deck Handset on the Boeing 777 provides clear audio quality, enabling effective communication even in noisy environments within the cockpit. The handset is equipped with noise-canceling technology, which filters out unwanted background noise and enhances the clarity of the communication exchange.
This feature is particularly important during critical phases of flight or in emergency situations when clear and concise communication is crucial for the safe operation of the aircraft. The flight crew can rely on the FDH to ensure that their messages are clearly understood and can be acted upon accordingly.
The Importance of the Flight Deck Handset (FDH)
The Flight Deck Handset (FDH) is a vital communication tool on the Boeing 777 aircraft, playing a significant role in ensuring the safety and efficiency of flight operations. Here are some reasons why the FDH is of utmost importance:
1. Emergency Communication
In the event of an emergency situation during flight, the FDH enables direct and immediate communication between the flight crew and relevant authorities or emergency response teams. This allows for the prompt dissemination of critical information, coordination of emergency procedures, and obtaining necessary assistance.
For example, in the case of a medical emergency on board, the flight crew can quickly contact medical professionals on the ground to seek guidance and support. The FDH ensures that important information is relayed accurately and any necessary actions can be taken without delay.
2. Operational Coordination
The FDH facilitates seamless coordination between the flight crew and ground personnel involved in the operational aspects of the flight. Effective communication is essential for tasks such as requesting pushback, receiving taxi instructions, coordinating maintenance activities, and addressing any issues that may arise before, during, or after the flight.
By using the FDH, the flight crew can efficiently relay important information, such as fuel requirements, passenger counts, special requests, or any operational updates, to the relevant parties. This helps ensure that all stakeholders involved in the flight are well-informed and can fulfill their respective responsibilities accurately and promptly.
3. Enhancing Situational Awareness
The Flight Deck Handset plays a crucial role in enhancing situational awareness for the flight crew. By having direct communication with air traffic control towers, they can receive real-time updates on weather conditions, traffic congestion, airport operations, or any other critical information that may impact the flight.
This helps the flight crew make informed decisions regarding flight routes, alternate airports, or any necessary deviations to ensure the safety and efficiency of the flight. The FDH enables continuous communication flow, allowing for immediate updates and adjustments as required.
The Flight Deck Handset (FDH) is a fundamental communication device in the cockpit of the Boeing 777 aircraft. Its various functions and features enable effective communication between the flight crew and ground personnel, enhancing safety, efficiency, and situational awareness during flight operations.
The FDH’s capabilities, such as two-way communication, call forwarding and diversion, and clear audio quality, provide the flight crew with the necessary tools to communicate with relevant authorities, coordinate operations, and ensure prompt responses in both normal and emergency situations.
The Flight Deck Handset plays a critical role in maintaining effective communication within the complex aviation environment, contributing to the overall safety and successful operation of the Boeing 777 aircraft.
