ASE/ADS-B

In view of the Brazilian undertaking to implement the PBCS concept in the Atlantic FIR and the work carried out with the Regional Monitoring Agencies in the South Atlantic region, CARSAMMA is coordinating with Brazil, the FAA (Federal Aviation Administration) and ICAO to train material and human resources to calculate ASE using satellite data obtained from ADS-B.

An ADS-B certified aircraft will be able to have its height maintenance monitored in the RVSM Airspace, as is already the case in the USA, China, Thailand and Australia, as shown in the figure below.

Countries that already use data obtained from ADS-B for
determine the Altimetric System Error (ASE) of an aircraft.

This collaboration will speed up the certification of aircraft to fly in RVSM Airspace, since, with the data provided, CARSAMMA will be able to issue the aircraft's ASE Letter without it needing to make a special monitoring flight, which will optimize the time spent on the process and save aircraft owners money. In some countries, such as the USA, it is enough for an aircraft to be ADS-B certified to fly in their RVSM Airspace.

Currently, the ASE of all aircraft in the South American and Caribbean Regions is calculated in CARSAMMA's Altimetry Laboratory, based on data obtained from a Monitoring Flight and meteorological conditions. This monitoring flight is carried out by a specialized company that has no connection with CARSAMMA. The whole process can take around 15 days.

It is expected that CARSAMMA will always have at least 03 professionals trained for this activity.
