The Air Traffic Safety Electronic Engineers Association on Tuesday called a three-hour “warning work stoppage” for Thursday, April 30, to protest staff and equipment shortages. The stoppage is to take place between 1 p.m. and 4 p.m. on April 30.

The safety engineer service, part of the Hellenic Civil Aviation Authority (YPA), expressed its concern over safety issues related to the increased summer passenger traffic due to “significant delays in upgrading and modernizing the VAR and PALLAS air navigation systems of YPA”. The group is also concerned about the danger posed by staff shortages, especially substitute and standby staff units.
