What is ASP on Boeing 777? (Audio Select Panel)

The Boeing 777, one of the most popular widebody aircraft in the world, is known for its advanced systems and technology. Among the many components that make up this impressive aircraft is the Audio Select Panel (ASP), a critical part of the communication system on board. In this article, we will delve into the details of the Audio Select Panel, its functions, and its importance in ensuring a smooth and efficient flight for passengers and crew.

The Audio Select Panel (ASP): A Vital Communication Tool

The Audio Select Panel on the Boeing 777, also known as the ASP, is a dedicated cockpit device that enables pilots to manage and control the aircraft’s audio system. It serves as a central control unit for various communication functions, ensuring seamless communication between the flight crew, air traffic control, and the cabin crew.

One of the key features of the Audio Select Panel is its ability to select different audio sources and adjust their volume levels. This includes the radio communications, cockpit speaker audio, and cabin interphone system. By using the ASP, pilots can easily switch between these different audio sources and control their volume settings, ensuring they can hear and communicate clearly with relevant parties.

In addition to audio source selection and volume control, the Audio Select Panel also allows pilots to manage the cockpit speaker audio. This means they can listen to important announcements and alerts from the cockpit speaker system, enhancing situational awareness and ensuring prompt response to critical information.

The ASP is strategically positioned within easy reach of the pilot, usually located on the center pedestal between the two pilot seats in the cockpit. Its user-friendly design, with clearly labeled buttons and knobs, enables pilots to quickly and accurately adjust audio settings and switch between different audio channels.

In terms of functionality, the Boeing 777 Audio Select Panel is a crucial tool for pilots to manage their audio environment. It plays a vital role in maintaining effective communication throughout the flight, ensuring that the flight crew can receive and transmit information reliably, and that the cabin crew can relay instructions to passengers smoothly.

The Importance of the Audio Select Panel in Aviation Safety

Aviation safety is of paramount importance in the operations of any aircraft, and the Boeing 777 is no exception. The Audio Select Panel on the Boeing 777 contributes to aviation safety in several ways.

Firstly, the ASP allows pilots to select and monitor the radio communications, which are essential for receiving and transmitting crucial information to air traffic control. Clear and accurate communication with ATC is vital for maintaining proper separation between aircraft and ensuring safe flight operations.

Secondly, the ability to adjust audio volume levels ensures that pilots can hear and understand radio transmissions and alerts without distraction or interference. This is particularly important during critical phases of flight, such as takeoff and landing, where effective communication is essential for safe maneuvering.

Furthermore, the cockpit speaker audio management feature of the Audio Select Panel allows pilots to stay informed about important announcements and alerts within the aircraft. By quickly and easily adjusting the audio settings, pilots can remain aware of any changes or emergency situations, enabling them to take appropriate action promptly.

Overall, the Audio Select Panel plays a critical role in aviation safety by ensuring effective communication between the flight crew, air traffic control, and the cabin crew. It enables pilots to manage their audio environment efficiently, enhancing situational awareness and contributing to the safe operation of the Boeing 777.


The Audio Select Panel, or ASP, is an essential component of the Boeing 777’s communication system. It provides pilots with the ability to control and manage the aircraft’s audio sources, ensuring seamless communication between the flight crew and other stakeholders. With its user-friendly design and crucial functions, the Audio Select Panel contributes to the safe and efficient operation of the Boeing 777. It plays a vital role in maintaining aviation safety and ensuring a smooth flight experience for passengers and crew alike.
