QUESTIONS & ANSWERS
The David Clark H3530 pushback headset includes a 30” straight communication cord terminated with a ¼” locking stereo plug. This makes it compatible with standard ground support belt stations such as the C35-XX Series, which are commonly used in pushback and ramp operations. The secure locking plug ensures stable communication without accidental disconnects during high-movement tasks.
The H3530 headset is designed specifically for ground support use and interfaces through a belt station like the David Clark C35-XX series. It is not directly compatible with all onboard aircraft intercom systems unless those systems are equipped with the correct ground interface. For ramp communications and pushback procedures, it functions as part of a complete David Clark communication system optimized for aviation ground operations.
This headset features a DC-1A amplified dynamic, noise-canceling microphone. It is engineered to provide excellent speech intelligibility in loud ramp environments. The over-molded, non-rotating boom assembly ensures durability while maintaining optimal mic placement, even during high-activity ground operations.
The H3530 provides a certified passive noise attenuation rating of 24 dB, which helps protect hearing in high-noise environments like airport ramps. This noise reduction level makes it suitable for use around jet engines, ground vehicles, and other sources of continuous, high-decibel sound exposure.
Yes! The headset is built for all-day wear with features like foam-filled ear seals, a ribbed head-pad, and pivoting stirrups on each ear cup. These design elements ensure a custom fit and comfort in all weather conditions. The headset’s spring-loaded headband further enhances stability and comfort during long ground handling shifts.
This model is specifically engineered for pushback and ramp operations with its dual-ear, over-the-head design and noise-canceling microphone. The rugged construction, reliable components, and superior noise attenuation help facilitate clear, uninterrupted communication with the cockpit crew, even in high-noise environments. It’s widely regarded as the benchmark headset for airline pushback use.
While not waterproof, the H3530 is built with materials and design features that withstand a wide range of environmental conditions. Foam ear seals and a durable composite shell help maintain performance and comfort during rain, cold, or hot weather, making it a reliable option for year-round ramp service.
The H3530 headset features a non-rotating, over-molded boom assembly that maintains its position for reliable voice transmission. Although it does not rotate freely, the boom is fixed at an optimal angle for consistent microphone placement, minimizing the need for frequent adjustments during pushback operations.
The ear domes are made from shallow ABS composite, and the headset uses chrome-finished carbon steel for its structural components. This blend of lightweight plastic and robust metal parts ensures the headset is both comfortable and highly durable, even in rugged ramp environments.
The H3530 headset operates through the belt station’s built-in electronics and requires a DC power supply of 8V to 16V with a source resistance of 200 to 2,200 ohms. This is standard for most belt stations used in airline ramp communication systems. It does not require direct charging or external battery packs.
With dynamic earphone elements and a frequency response of 200 to 5,500 Hz, the headset delivers clear reception and speech transmission tailored for voice clarity. The noise-canceling mic adds to this by filtering out background noise, making it easier to communicate clearly in noisy environments.
David Clark offers a five-year warranty on its ground support headsets, including the H3530. This warranty covers manufacturing defects in materials and workmanship. Users should retain proof of purchase and register their headset with David Clark for support and service claims.
