“…Gopalswamy et al (2015) showed that in solar cycle 24, more halo Coronal Mass Ejections (CMEs) were recorded than in solar cycle 23 even though the solar sunspot number decreased. Kharayat et al (2017) studied CMEs and the associated solar flares for the years 1997-2014. They showed that halo CMEs are most effective at producing SEPs.…”

Solar radio bursts have been associated with a number of disruptions in avionic systems. The objective of this work is to develop solar radio burst interference thresholds which account for the technical specifications of aviation related instrumentation, instrument operating frequencies as well as industry stipulated error tolerances. Solar radio bursts are suggested to be potentially hazardous when exceeding these calculated thresholds. Particular attention is paid to the radio altimeter, an important component in aviation safety. The thresholds suggested in this work for VHF communication, GPS navigation receivers and radio altimeter frequencies are; 102 , 103 and 104 sfu respectively. Solar radio burst interference (for solar radio bursts above 104 sfu) is shown to result in large errors (64-251 m) in the altitude estimates for the Frequency Modulated Continuous Waves (FMCW) radio altimeter simulated in this work.
