Brazilian and Italian aircraft differ considerably in their avionics, Italian aircraft being equipped with various NATO systems which were considered redundant in the South American theatre. AMXs in Brazilian service are often fitted with one of three pallet-mounted sensor packages, which contain various vertical, oblique, and forward-facing cameras, for performing the aircraft's secondary aerial reconnaissance role. A simple ranging radar is equipped for targeting purposes, however the specific radar also differs between both operators. The flight system employs a GE Avionics flight control computer. Extensive electronic countermeasure (ECM) are fitted to protect the aircraft, include passive receiver antenna on the tailfin and an active jammer pod that is typically mounted on one of the aircraft's hardpoints.
