GNSS-based navigation is commonly used in aircrafts as one source for localisation. As reports of pilots about jamming during flight are becoming more frequent, we performed jamming tests with a parked passenger aircraft to assess the criticality of jamming events. We observed the reaction of the aircrafts GPS‑position display in the cockpit and the ADS-B availability during jamming. We analysed the relative power levels at which the GPS-receivers and also the ADS-B broadcasting show negative effects. Beyond others, we could observe significantly long recovery times of the GPS‑position display and the ADS-B system. The results give unique detailed facts about the vulnerability of one type of commercial passenger aircraft and emphasize how important it is to raise awareness of this vulnerability in aviation safety.
