DIY program for smaller aircraft

AlgoPlus has traffic denominators for aerodromes and larger aircraft but not for smaller aircraft. Our AlgoPlus program (DIYStat) for operators with smaller aircraft compares the operators’ CADORS reported performance with the national norms.

Step 1) Emailed Report gives number of reports
Step 2) User enters number of operations
Step 3) DIYStat program converts CADORS event counts to rates per 100,000 movements
Step 4) DIYStat program shows airline’s "Relative Risk", how it compares with the Canadian statistical norm and whether the result is statistically significant

With these external data smaller operators can learn how their performance compares to the statistical norm
