Number of Reports
Month and Year
Figure 52 shows the number of reports recorded in the Agency’s IORS system for the years 2013 and 2014 by
month. Typically the summer and winter holiday months are the periods with the highest aviation activity and
this is reflected in the increased number of reports received during these times.
