By Tim Hepher PARIS (Reuters) -Regulators have called for more rigorous checks when pulling some Airbus jets out of pandemic storage, following flawed cockpit readings that can suggest blocked sensors. Pilots rely on airspeed readings derived from external probes known as pitot tubes, which can become blocked by insect nests or dirt if they are not properly sealed during storage. The European Union Aviation Safety Agency (EASA) said in a safety directive covering the Airbus A320 family that "an increasing number of operational disruptions have been reported due to airspeed discrepancies" as they return to the air. A spokesperson said the events included commercial flights and in most cases led to aborted takeoff. "EASA had no reports of any resultant injuries, aircraft or system issues," she said. Asked whether passengers had been on board, an Airbus spokesperson said it did not have a breakdown between passenger, freight or technical check flights.
