Arinc Direct announced it is now delivering westbound oceanic clearances via datalink on North Atlantic routes. Westbound clearance delivery is available to business airplanes equipped with the Teledyne Telelink RMU (radio management unit) or Universal Avionics Unilink CMU (communications management unit), which are compliant with the Arinc 623 standard. The westbound service joins current eastbound services and is coordinated with the UK’s oceanic route clearance authorization system at the Shanwick control center in Shannon, Ireland.
