Part 3 covers Task C: Weather Information, including the significant expansion of knowledge topics in the 2024 ACS. I also backtrack briefly to cover the minor changes to Tasks A and B in the updated ACS. The key takeaway: as a VFR private pilot, you need to avoid the weather — not fly into it. I need you to read a METAR, interpret a TAF, and make a sound go/no-go decision.

ACS Elements at a Glance

PA.I.C.K1 Sources of weather data (NWS, Flight Service)
PA.I.C.K2 Weather products for preflight planning (expanded in 2024 with ~8 new sub-elements covering METARs, TAFs, winds aloft, PIREPs, AIRMETs/SIGMETs, surface analysis, prog charts, and convective outlooks)
PA.I.C.K3 Meteorology applicable to the departure, en route, and arrival
PA.I.C.K4 Flight deck weather displays
PA.I.C.R1–R2 Go/no-go factors and limitations of weather equipment/reports
PA.I.C.S1–S4 Obtain a briefing, analyze weather, make go/no-go, correlate conditions
What Examiners Want to Hear

Instead of just saying “it’s a no-go,” demonstrate higher-level decision-making. “The ceilings are low along my direct route, but to the north it’s clear. I’d reroute north and add a fuel stop as a buffer.” That answer shows risk mitigation, not just cancellation. The easy answer is always to cancel — I want to see you work the problem.

2024 ACS Changes for Tasks A & B: Task A added a BasicMed advisory circular reference and a link to the AFH. Task B added a new element on owner/operator PIC responsibilities (PA.I.B.K1e) and standard vs. special airworthiness certificates. The ACE Guide covers both with links to the Plane Sense handbook.
