Risk Management — The applicant is able to identify, assess, and mitigate risk associated with:

PA.I.C.R1 Making the go/no-go and continue/divert decisions, including:

PA.I.C.R1a a. Circumstances that would make diversion prudent

PA.I.C.R1b b. Personal weather minimums

PA.I.C.R1c c. Hazardous weather conditions, including known or forecast icing or turbulence aloft

PA.I.C.R2a a. Installed onboard weather equipment

PA.I.C.R2b b. Aviation weather reports and forecasts

PA.I.C.R2c c. Inflight weather resources

Skills — The applicant exhibits the skill to:

PA.I.C.S1 Use available aviation weather resources to obtain an adequate weather briefing.

PA.I.C.S2 Analyze the implications of at least three of the conditions listed in K3a through K3l, using actual weather or weather conditions provided by the evaluator.

PA.I.C.S3 Correlate weather information to make a go/no-go decision.
