AA.I.C — Weather Information (ATP)

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

Knowledge

The applicant demonstrates understanding of:

• AA.I.C.K1Sources of weather data (e.g., National Weather Service, Flight Service) for flight planning purposes.
• AA.I.C.K2Acceptable weather products and resources utilized for preflight planning, current and forecast weather for departure and en route operations and arrival phases of flight.
• AA.I.C.K3Meteorology applicable to the departure, en route, alternate, and destination for flights conducted under Instrument Flight Rules (IFR) to include expected climate and hazardous conditions such as:
  • AA.I.C.K3aa. Atmospheric composition and stability
  • AA.I.C.K3bb. Wind (e.g., crosswind, tailwind, windshear, mountain wave, etc.)
  • AA.I.C.K3cc. Temperature
  • AA.I.C.K3dd. Moisture/precipitation
  • AA.I.C.K3ee. Weather system formation, including air masses and fronts
  • AA.I.C.K3ff. Clouds
  • AA.I.C.K3gg. Turbulence
  • AA.I.C.K3hh. Thunderstorms and microbursts
  • AA.I.C.K3ii. Icing and freezing level information
  • AA.I.C.K3jj. Fog/mist
  • AA.I.C.K3kk. Frost
  • AA.I.C.K3ll. Obstructions to visibility (e.g., smoke, haze, volcanic ash, etc.)
• AA.I.C.K4Flight deck displays of digital weather and aeronautical information, their use to navigate around weather, and equipment limitations.
• AA.I.C.K5Low-visibility operations (e.g., surface movement, category II and III approaches). (ATP AMEL, AMES)
• AA.I.C.K6Flight Risk Assessment Tools.

Risk Management

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

• AA.I.C.R1Weather conditions involved in departure and in-flight decision making, to include:
  • AA.I.C.R1aa. Circumstances requiring a change in course or destination
  • AA.I.C.R1bb. Known or forecast icing, winds or turbulence aloft, volcanic ash, destination weather, etc.
  • AA.I.C.R1cc. Personal minimums
  • AA.I.C.R1dd. Operator specified or aircraft operational limitations, if applicable
• AA.I.C.R2Limitations of:
  • AA.I.C.R2aa. Onboard weather equipment
  • AA.I.C.R2bb. Aviation weather reports and forecasts
  • AA.I.C.R2cc. Inflight weather resources

Skills

The applicant demonstrates the ability to:

• AA.I.C.S1Interpret weather information, apply principles of aeronautical decision-making, and use a Flight Risk Assessment Tool, if available.
