Atran Airlines Invests in Boeing 737-400F System Upgrade

Atran Airlines, part of Russia’s Volga-Dnepr Group, has contracted Fokker Services in the Netherlands to upgrade its Boeing 737-400SF freighter aircraft with the latest version of the Traffic Collision Avoidance System (TCAS).

Modernisation of its fleet will ensure Atran continues to operate in full compliance with the requirements of Eurocontrol, the international organisation composed of Member States of the E.U. that oversees air traffic management.

Atran is upgrading its TCAS system from v.7.0 to the new v7.1 in accordance with the new European Commission mandate effective from December 2015 that requires all aircrafts above 5,700kg Maximum Take-off Weight or authorised to carry more than 19 passengers to be equipped with the latest TCAS version.

The Traffic Collision Avoidance System monitors the airspace around an aircraft for other aircraft equipped with a corresponding active transponder which may present a threat of mid-air collision.

The new 7.1 version is able to implement corrective action in the case of one of the crews not adhering to the TCAS recommendations.
