✈️ Aviation Brief — Issue #22
Weekly insights for student pilots and the instructors who train them.
THIS WEEK'S TOPIC
PA.I.D — National Airspace System (Private Pilot ACS)
### 1. ACS STANDARDS SUMMARY
For PA.I.D (National Airspace System) at the Private Pilot level, the FAA ACS requires you to demonstrate **instructional knowledge** by describing in detail the following elements from sources like 14 CFR parts 71 and 91, the AIM (Chapters 3-1 through 3-2), sectional charts, and the Chart Supplement:
- Airspace classifications (Classes A through G), their requirements, chart depictions, entry procedures, and visibility/ceiling minimums for VFR operations.
- Special Use Airspace (e.g., prohibited, restricted, warning areas) and other airspace areas (e.g., MOAs, alert areas, controlled firing areas).
- ATC services, procedures, separation, communications, and phraseology.
- Wake turbulence avoidance.
- Navigation methods and position reporting.
- Land and Hold Short Operations (LAHSO).
- Runway incursion, excursion, and incorrect runway avoidance.
- Sources for obtaining information on airspace, such as NOTAMs and the Chart Supplement.
The examiner expects you to explain these clearly, using real-world examples like sectional chart symbols, without prompting—think oral exam on how you'd safely operate in Vegas airspace around McCarran (KLAS) Class B.
### 2. THREE COMMON STUDENT MISTAKES
- **Mixing up Class B vs. Class C entry requirements**: Students often forget Class B needs prior ATC clearance (not just communication), while Class C requires two-way radio contact—leading to busted airspace during checkrides when describing approaches to busy towers like KLAS.
- **Forgetting VFR weather minimums by airspace class**: Many recite 3 SM visibility/1,000 ft ceilings for all controlled airspace, missing the 1 SM/500 ft below 10,000 MSL MSL for Class E or Class G specifics at night (1 SM/1 SM clear of clouds above 1,200 AGL).
- **Overlooking special use airspace chart symbols and activation**: Pilots blank on magenta hash marks for alert areas or how to check MOA status via FSS/ATIS, resulting in "what if" scenarios where they fly unaware into active military ops.
### 3. CFI PRO TIP
Print a current Las Vegas sectional chart and laminate it—then use dry-erase markers during ground lessons to have students circle and label every airspace boundary, symbol, and transition route in real-time while quizzing entry rules. This hands-on "chart surgery" builds visual memory faster than flashcards and mimics real preflight planning for our C-172 cross-countries.
### 4. SAFETY SPOTLIGHT
Poor National Airspace System knowledge contributes to runway incursions, with FAA data showing over 1,800 events annually; a 2022 NTSB report (ASRS callback #2304) highlighted a Part 91 Cessna 172 incursion at a Class D airport where the pilot misread the sectional, entered an active runway without clearance, narrowly avoiding collision—emphasizing always cross-checking Chart Supplements and tower instructions before taxiing.
### 5. DID YOU KNOW
Class G airspace—the most permissive for VFR—extends from the surface up to 1,200 feet AGL (or 14,500 MSL in some remote areas), but requires 1 statute mile visibility at night under Part 91.155, making it a go-to for desert VFR hops around Vegas but a trap if you don't verify altitudes on the chart.
