A Chair Airlines flight bound for Pristina returned to Zurich Airport shortly after takeoff on Friday evening following a technical alert. The aircraft, operating as flight CS602, triggered a 7700 emergency code at 5:50 p.m. local time, prompting the flight crew to abort their climb and return to the departure airport, where the plane landed safely.
Technical Response to Cabin Pressure Alert
According to Nicolas Bühler, Chief Operating Officer of Chair, the decision to return was prompted by an indicator related to the aircraft’s cabin pressure system. While the emergency code 7700 is used in aviation to signal a critical situation and grant an aircraft absolute priority during landing, the airline stated that no formal “air emergency” was declared. The crew opted to hold the aircraft in the vicinity of Zurich Airport to evaluate the technical issue before deciding to land as a precautionary measure. Both the airline and Zurich Airport confirmed that the landing was conducted safely and that no passengers or crew members were injured.
