Reduced Vertical Separation Minima (RVSM), or Domestic RVSM (DRVSM), is the term used to describe a reduction in the vertical distance allowed between aircraft as mandated by most aviation authorities in certain airspaces (e.g. airports). Reducing the distance allows more aircraft to fly in the same location. To ensure safety for an increase in air traffic, more accurate information on an aircraft’s altitude is required. To fly in RVSM-designated airspace, most aircraft must be fitted with an air data computer that is RVSM-compliant. These include Curtiss-Wright’s Enhanced Software Configurable Air Data Unit (ESCADU) air data computer and the range of new air data products based on the Air Data Computer Module (ADCM).
Curtiss-Wright’s new line of air data products are based on the ADCM, which uses vibrating-cylinder technology to provide accurate data while remaining less prone to drift. The resulting accuracy and reliability also reduce maintenance costs. The ADCM can be integrated into existing avionics systems or can be purchased as a standalone unit as a replacement for the ESCADU. Integrated probe options are also available that reduce the pneumatic piping and wiring required for installation.
