100A MLS (Air Data) Features and Specifications *
The Air Data 100A MLS ADI-20203-001 Microwave Landing System Ramp Test Set is a specialized portable instrument designed for flight line use, ensuring the proper functionality of installed Microwave Landing System (MLS) receivers. The Air Data 100A MLS performs verification by transmitting a signal on MLS channel 500, which checks various functions of the MLS receiver, including Azimuth, Back Azimuth, Elevation, and Clearance pulses. This compact and rugged unit is tailored for different flight applications and provides up to 3 hours of continuous operation on its internal rechargeable batteries.
The 100A MLS allows operators to select predefined angle configurations through a single control, generating fixed or variable deviations on the aircraft's Glideslope and Localizer. This streamlined operation simplifies the process, ensuring efficient checks and the accuracy of the MLS system. The design includes features like water resistance during operation and a built-in RF attenuator, enhancing its reliability and ease of use in various environments.
The ADI-20203-001 test set operates within a specific RF frequency range and conforms to FAA standards, offering multiple operational modes to suit different testing requirements. Its indicators provide clear information about battery levels, charging status, and AC power, ensuring the operator is always aware of the device's status. With its detailed operation and maintenance manual, the Air Data 100A MLS Ramp Test Set is an essential tool for maintaining the operational readiness of MLS systems in aviation.
The Air Data 100A MLS price and features make it a very attractive option compared to similar microwave landing system ramp test sets available on the market.
