COMM.I.C — Weather Information

Objective: To determine that the applicant exhibits satisfactory knowledge, risk management, and skills associated with weather information for a flight under VFR.

Knowledge

• CA.I.C.K3Meteorology applicable to the departure, en route, alternate, and destination under VFR in Visual Meteorological Conditions (VMC) to include expected climate and hazardous conditions such as:
  • CA.I.C.K3aa. Atmospheric composition and stability
  • CA.I.C.K3bb. Wind (e.g., crosswind, tailwind, windshear, mountain wave, etc.)
  • CA.I.C.K3cc. Temperature
  • CA.I.C.K3ff. Clouds
  • CA.I.C.K3gg. Turbulence

  • CA.I.C.K3kk. Frost
  • CA.I.C.K3ll. Obstructions to visibility (e.g., smoke, haze, volcanic ash, etc.)
• CA.I.C.K4Flight deck displays of digital weather and aeronautical information.

Risk Management

The applicant demonstrates the ability to identify, assess and mitigate risks, encompassing:

• CA.I.C.R1Factors involved in making the go/no-go and continue/divert decisions, to include:
  • CA.I.C.R1aa. Circumstances that would make diversion prudent
  • CA.I.C.R1bb. Personal weather minimums
  • CA.I.C.R1cc. Hazardous weather conditions to include known or forecast icing or turbulence aloft
• CA.I.C.R2Limitations of:
  • CA.I.C.R2aa. Onboard weather equipment
  • CA.I.C.R2bb. Aviation weather reports and forecasts
  • CA.I.C.R2cc. Inflight weather resources

Skills

The applicant demonstrates the ability to:

• CA.I.C.S1Use available aviation weather resources to obtain an adequate weather briefing.
• CA.I.C.S2Analyze the implications of at least three of the conditions listed in K3a through K3l above, using actual weather or weather conditions in a scenario provided by the evaluator
• CA.I.C.S3Correlate weather information to make a competent go/no-go decision.
