PA.I.C.K3l l. Obstructions to visibility (e.g., smoke, haze, volcanic ash, etc.)
PA.I.C.K4 Flight deck instrument displays of digital weather and aeronautical information.
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.R2 Use and limitations of:
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.
