▪ The NSA has cautioned that the ANSP might not be able to achieve the RP3 targets. The issue is related to the understanding of the EoSM guidance on specific aspects.
▪ Switzerland recorded the same rate of runway incursions, and lower rate of separation minima infringements despite significant traffic increase.
▪ Skyguide do not use automated safety data recording systems for runway incursions.
