THIS WEEK'S TOPIC
PA.I.C — Cross-Country Flight Planning (Private Pilot ACS)
### 1. ACS STANDARDS SUMMARY
For Private Pilot Airplane ACS Task PA.I.C (Cross-Country Flight Planning), the examiner expects you to demonstrate the ability to plan a VFR cross-country flight by selecting an appropriate route of flight, obtaining and analyzing all available weather reports and forecasts, computing takeoff and landing distances, weight and balance, fuel requirements (including reserves), and groundspeed estimates. You'll explain how to file a flight plan (or flight following), select visual checkpoints and alternates, and outline emergency procedures. Knowledge elements include FARs on flight planning, navigation aids, performance charts, and risk management like personal minimums for weather and fuel.
### 2. THREE COMMON STUDENT MISTAKES
- **Underestimating fuel requirements**: Students often forget to add the FAA-required 30-minute day VFR reserve or fail to factor in actual winds aloft, leading to overly optimistic endurance estimates—I've seen checkride busts where the plan showed only 20 minutes of reserve.
- **Poor checkpoint selection**: Picking landmarks that aren't visible from cruise altitude (like small roads or fields) or spacing them too far apart, which makes navigation tough in haze or at night; examiners ding this during oral prep when you can't justify visibility from 3,500 feet AGL.
- **Skipping weight and balance verification**: Loading bags or passengers without recalculating CG after initial empty aircraft weights, resulting in aft-heavy conditions that surprise you on the first leg—common in Cessna 172 training when students eyeball it instead of using the chart.
### 3. CFI PRO TIP
Always build your cross-country plan "backwards" from the destination: Start with alternates and reserves first, then work fuel burn from there using winds aloft data from 1800wxbrief.com. Print it out, highlight key numbers, and verbally walk through it with your CFI like you're briefing ATC—this forces you to catch errors early and builds confidence for the checkride oral.
### 4. SAFETY SPOTLIGHT
Fuel exhaustion remains a top killer in general aviation cross-country flights, with NTSB data showing over 150 accidents from 2018-2022 where pilots ran dry despite ample fuel on board—often due to unforecast headwinds or diverted attention from navigation (e.g., NTSB ID CEN20FA287, a Cessna 172 that ditched after burning extra chasing a tailwind that flipped to headwind). ASRS reports echo this: 40% of VFR fuel-related incidents tie back to optimistic planning without real-time wind checks. Lesson: Refile or land early if winds shift en route.
### 5. DID YOU KNOW
You're not legally required to file a VFR flight plan for cross-country flights under Part 91, but activating flight following with ATC is free, provides traffic alerts, and lets search-and-rescue know your route if you go missing—many Vegas students swear by it for flying over the busy desert terrain.
