The Audio Select Panel (ASP) is an important component of the Boeing 737 aircraft that controls the audio system. It is a part of the Integrated Audio System (IAS) and is responsible for managing and selecting audio sources for various communication and warning systems in the aircraft.
The ASP is located on the overhead panel, above the cockpit, within easy reach of the flight crew. It consists of a series of switches and knobs that enable the pilots to control and manage the audio functions of the aircraft.
The ASP is designed to provide the flight crew with easy access and control over the different audio sources and communication channels, allowing them to effectively communicate with air traffic control, passengers, and other crew members. It plays a crucial role in ensuring clear and reliable communication during all phases of flight.
Now let’s take a closer look at the various functions and features of the Audio Select Panel on the Boeing 737.

The Functions of the Audio Select Panel
The Audio Select Panel on the Boeing 737 has several important functions that contribute to the overall audio management on the aircraft:
1. Audio Source Selection
One of the primary functions of the Audio Select Panel is to allow the pilots to select different audio sources for communication and warning systems. The panel has dedicated switches and knobs for selecting audio sources such as VHF radios, interphones, public address systems, and more.
By using the switches and knobs on the ASP, pilots can easily switch between different audio sources based on their requirements and the phase of flight. This ensures that the appropriate audio source is selected and routed to the correct communication system.
2. Audio Volume Control
Another important function of the ASP is to control the volume of audio outputs. The panel features individual volume controls for different audio sources, allowing the pilots to adjust the volume levels as needed.
The volume control knobs on the panel provide a convenient way for the flight crew to adjust the audio levels, ensuring clear and audible communication with air traffic control, passengers, and other crew members.
3. Audio Isolation
The Audio Select Panel also includes an audio isolation function, which allows the pilots to selectively isolate audio systems. This feature helps in troubleshooting and isolating audio-related issues in case of any malfunctions or abnormalities.
In situations where a particular audio system is causing interference or disturbance, the pilots can use the audio isolation feature to isolate and disable that specific audio source. This ensures that the rest of the audio systems operate normally without being affected by the faulty system.
Benefits of the Audio Select Panel
The Audio Select Panel on the Boeing 737 offers several benefits to the flight crew, contributing to the overall efficiency and safety of the aircraft:
Efficient Audio Management
The ASP provides an efficient means of managing the audio functions of the aircraft. With dedicated switches and knobs for audio selection, volume control, and isolation, the flight crew can easily access and control the various audio sources and communication channels.
By having a centralized control panel, the pilots can quickly respond to communication requirements, ensure clear and uninterrupted audio transmission, and handle emergency situations effectively.
Enhanced Communication
The Audio Select Panel plays a vital role in maintaining effective communication between the flight crew and external entities such as air traffic control, passengers, and other crew members. By allowing the pilots to select and control audio sources, the ASP ensures that critical information is transmitted clearly and accurately.
Clear and reliable communication is essential for flight safety and coordination. The ASP enables the flight crew to establish and maintain effective communication channels throughout the entire duration of the flight.
Quick Troubleshooting
The audio isolation feature on the ASP enables the flight crew to quickly troubleshoot and address any audio-related issues. By selectively isolating audio systems, the pilots can pinpoint the source of the problem and take appropriate actions to resolve it.
This feature saves valuable time during troubleshooting procedures, allowing the pilots to focus on resolving the issue promptly and minimizing any disruptions to audio communication.
Conclusion
The Audio Select Panel (ASP) on the Boeing 737 is a critical component of the aircraft’s audio system. It provides the flight crew with easy access and control over different audio sources and communication channels, ensuring clear and reliable communication during all phases of flight.
By enabling audio source selection, volume control, and isolation, the ASP enhances the efficiency and safety of audio management on the aircraft. It allows the flight crew to effectively manage communication requirements, maintain clear and uninterrupted audio transmission, and troubleshoot any audio-related issues.
The Audio Select Panel plays a crucial role in facilitating communication between the flight crew and external entities, contributing to overall flight safety and coordination. Its presence on the Boeing 737 aircraft underscores the importance of audio management in the aviation industry.
