ISU Flight Training Ground School Notes (Comprehensive)

Recency of Experience and sets for flight training

• Night definition varies by context:
  • General night definition for CFI ground school: from sunset to sunrise.
  • Recency of experience uses a narrower window: one hour after sunset to one hour before sunrise (to count as recent experience).
• Progression to multi-engine training creates two sets of recency requirements:
  • You may be current in single-engine land, but not automatically current in multi-engine land.
  • Categories vs. classes clarify what counts for recency: categories (e.g., airplane, rotorcraft) and classes (e.g., airplane single-engine land, airplane multi-engine land).
• After graduating with multi-engine rating on your commercial certificate, you will have two sets of recency: airplane single-engine land and airplane multi-engine land.
• Current status must be maintained separately for each set; time you log toward multi-engine recency does not count for single-engine recency, and vice versa.
• Practical implication: if you become current in multi-engine, you still need to perform the required takeoffs and landings in the daytime and at night for the single-engine set as well.

Preparation for a private pilot certificate and student pilot specifics

• Required documents to fly as a private pilot:
  • Pilot certificate (private), photo ID, a medical certificate or BasicMed.
• For the student pilot certificate, the logbook is required when flying solo:
  • Endorsements are logged by the flight instructor in your logbook after you complete stage checks.
• Student pilot endorsement rules and timing:
  • Student pilot solo endorsement is valid for $90 ext{ days}$.
  • Initial solo endorsement is also valid for $90 ext{ days}$.
• Solo flight minimums (as per FAA regulations for the solo phase):
  • Minimum visibility: $3 ext{ miles}$.
  • Maximum distance for local student solo: $25 ext{ miles}$.
• ISU SOPs may specify different requirements for BIS and signals; always refer to local SOPs for exact procedures.
• Initial solo specifics:
  • After dual cross country training, the instructor authorizes solo cross country with an endorsement for that specific cross country.
  • For the first solo cross country, you typically need multiple endorsements (pre-solo, initial solo, cross country instruction, and the specific cross country endorsement).
  • The first solo cross country preparation generally includes a pre-solo exam endorsement and a cross country endorsement for the airports involved in your planned route.
• Endorsement sequence for the first solo cross country (typical):
  • Pre-solo endorsement (for written or knowledge components)
  • Initial solo endorsement
  • Cross country instruction endorsement
  • Specific cross country endorsement for the airports you’ll fly to
• Endorsement validity and renewal:
  • The only endorsement with a built-in validity period is the initial 90-day solo endorsement; you must renew every $90 ext{ days}$ if you remain solo.
• Instructor awareness and safety culture:
  • Flight instructors typically stay ahead of endorsement requirements, but some instruction is introduced in ground school due to safety considerations.
• Safety briefing context:
  • A safety briefing for freshmen (Homestead Hall 102, 5–6 PM) demonstrates integration of safety management and SOP changes into training.
• FAA oversight and ramp checks:
  • FAA inspectors visit ISU periodically, roughly three times per year during a typical four-year program; ramp checks may occur 8–10 times overall.
  • A ramp check involves inspectors approaching the aircraft after you shut down and asking to review documents and the aircraft’s airworthiness in detail.
  • Documents typically checked include: airworthiness certificate, aircraft registration, the operator’s handbook, and the weight-and-balance certificate.
  • Inspectors also review placards listed in the AFM (Airplane Flight Manual) and check the compass card and compass calibration history.
  • Compass considerations: electrical interference from components like the alternator/generator can affect compass readings; compass cards indicate recalibration history.
  • Modern cockpit equipment (headsets, iPads) can influence compass accuracy; ensure proper placement and use during flight.

Categories, classes, and types in aircraft certification

• Definitions:
  • Category: the broadest grouping for certification (e.g., airplane, rotorcraft, glider, lighter-than-air, power lift).
  • Class: a subdivision within a category (e.g., single-engine land, single-engine sea, multi-engine land, multi-engine sea).
  • Type: a specific model or variant (e.g., Cessna 172, Piper PA-28-181, etc.).
• Examples and explanation:
  • A given airplane can be certificated in multiple categories/classes depending on its use; e.g., some airplanes are certificated in both normal and utility categories.
  • Normal category vs. utility category differences:
  • Utility category allows higher stresses in certain g-forces (positive and negative G).
  • A given airplane’s AFM defines its category, class, and type.
• Common categories with examples:
  • Normal, Utility, Experimental, Transport, Restricted, and Aerobatic categories.
  • Each category supports different flight envelopes and operations.
• Real-world relevance and career paths:
  • Airplanes may be operated under Part 91, Part 91K (private operator), or Part 135 (charter) depending on usage.
  • Part 91K describes private operators; Part 135 covers charter operations with different training/refresh requirements.
  • Some professionals move between categories and classes as their careers evolve (e.g., private pilot to corporate flight, freight, or airline work).
• Practical implications for training and insurance:
  • After earning a private certificate, pilots often pursue refresh or recurrent training to maintain skills for different categories/classes (e.g., moving from single-engine land to multi-engine land).
  • Insurance and rental requirements may require aircraft-specific checkouts (often 1–2 hours) before renting, depending on the operator.
• Additional notes on aircraft types and home base training:
  • A high-performance aircraft is defined as an airplane with more than $200 ext{ horsepower}$.
  • Mountain flying hazards are discussed in training; seek instruction from a qualified instructor for mountain operations.

Practical implications for logging hours and cross-certifications

• Time flown outside your home program:
  • Time flown as a private pilot outside ISU can be logged, but it does not count toward the curriculum hours required for instrument, commercial, etc.
  • You can accumulate flight hours elsewhere and still need to complete the specific curriculum hours within the ISU program to earn instrument and/or commercial certificates.
• Example scenario:
  • A student may earn a private certificate, log 300 hours elsewhere, then return to ISU and complete the required 120 hours for the instrument rating or commercial certificate.
• Summary takeaway:
  • Logging hours outside the school is permissible for experience and practice, but it does not replace the curriculum-relevant hours required for certification.

Conceptual recap and connections to foundational FAA rules

• The material ties into Part 61 certification processes and the recency of experience concepts (category and class-based recency, and flight currency).
• Understanding endorsements, their validity, and how they apply to solo and cross-country operations is essential for safe flight operations and regulatory compliance.
• The ramp check process and the emphasis on documenting airworthiness, registration, and weight-and-balance reflect broader aviation safety and oversight principles.
• Awareness of high-performance aircraft definitions and the implications for training, currency, and insurance is important for career planning and safety planning.

Quick reference: key numbers and terms in this session

• Solo visibility minimum: $3 ext{ miles}$
• Solo local distance limit: $25 ext{ miles}$
• Solo endorsement validity (initial solo): $90 ext{ days}$
• High-performance aircraft: horsepower > $200 ext{ hp}$
• Recency windows for night flying: one hour after sunset to one hour before sunrise (recency, not general night definition)
• Ramp check frequency: several times over a four-year program (roughly 8–10 checks total)
• Major categories/classes examples: airplane single-engine land, airplane multi-engine land, airplane single-engine sea, airplane multi-engine sea

Notes on future study and cross-references

• Review Part 61 certification requirements, including category and class definitions, for a deeper understanding of how recency and currency apply to different flight scenarios.
• Study the AFM for specific aircraft you train in, including the presence of placards, compass calibration procedures, and weight-and-balance information.
• Familiarize yourself with your institution's SOPs for student pilot operations, BIS/Signals requirements, and any location-specific endorsements or limitations.
• Consider refresher training and practice flights for mountain flying, cross-country planning, and high-performance aircraft handling to maintain currency and safety across different flight contexts.
