You, the pilot
Every oral opens here. The DPE confirms — before you walk to the airplane — that you are legally allowed to fly. ACS task: I.A — Pilot Qualifications.
What you must carry — 61.3
On your person or readily accessible in the aircraft (flight bag in cockpit qualifies; car at FBO does not):
- Pilot certificate
- Medical certificate, OR BasicMed documents + US state-issued photo ID
- Government-issued photo ID (separate item — required since 2003)
61.51(i): a PPL is not required to carry their logbook, except to demonstrate a specific endorsement or training record needed for the operation.
Medical — 61.23
| Class | Privileges | < 40 at exam | ≥ 40 at exam |
|---|---|---|---|
| 1st | ATP → Cmcl → Pvt | 6 / 12 / 60 mo | 6 / 12 / 24 mo |
| 2nd | Commercial → Pvt | 12 / 60 mo | 12 / 24 mo |
| 3rd | Private | 60 calendar months | 24 calendar months |
"Calendar month" expires on the last day. Exam Feb 12, 2025 at age 35 → valid through Feb 28, 2030. Age at exam determines duration. Turn 40 the day after — still get 60 months.
Logbook — 61.51
Must log: training for ratings/endorsements/currency, experience used to meet currency or a future rating requirement.
Need not log: everything else. Most pilots log it all anyway for insurance and personal record.

The layered cake
Where can you fly, what equipment do you need, and what are the weather mins? ACS: I.E Cross-Country Planning, I.H Operation of Systems.
Classes at a glance
| Class | Vertical | Equipment to enter | VFR mins |
|---|---|---|---|
| A | 18,000 MSL to FL600 | IFR clearance, Mode C, ADS-B Out | IFR only |
| B | SFC to ~10,000 MSL (inv. wedding cake) | Clearance, Mode C, 2-way radio, ADS-B Out | 3 SM, COC |
| C | SFC to 4,000 AGL; 5/10 NM rings | 2-way est., Mode C, ADS-B Out | 3 SM, 500/1000/2000 |

| E | Everything controlled, not A/B/C/D | None below 10k MSL (Mode C+ADS-B above 10k MSL excl. ≤2500 AGL) | Depends on altitude |
| G | SFC up to base of E (700/1,200 AGL typical) | None | Reduced — see Phase 3 |
Special Use Airspace
| Type | What it means |
|---|---|
| Prohibited (P-) | No flight allowed. P-40 Camp David, P-49 Crawford, etc. |
| Restricted (R-) | Hazards to non-participating aircraft. Entry requires controlling agency permission. Check NOTAM and chart for hours. |
| Warning (W-) | Same hazards as restricted but over international waters (3+ NM offshore). No US authority to prohibit, but avoid. |
| MOA | Military Operations Area. VFR may enter — exercise caution, get flight following. |
| Alert (A-) | High volume training. Both transiting and participating pilots are responsible for collision avoidance. |
| CFA | Controlled Firing Area. Activities suspended when an aircraft is detected. Not charted (no need to avoid). |
| NSA | National Security Area. Voluntary avoidance requested; can be made temporarily prohibited by NOTAM. |
TFRs — Temporary Flight Restrictions
| Rule | Subject |
|---|---|
| 91.137 | Disaster / hazard areas |
| 91.138 | National disaster in Hawaii |
| 91.141 | Presidential / VIP movement |
| 91.143 | Space flight operations |
| 91.145 | Major sporting events / large gatherings (Super Bowl, NASCAR, etc.) |
Check tfr.faa.gov before every flight. TFRs are published by FDC NOTAM.
Mock oral · Airspace
Procedures, comms, human factors
The AIM is non-regulatory but operationally authoritative. DPEs ask the bits that affect every flight — comms, light gun, NOTAMs, wake, ADM, aeromedical. ACS: I.G Human Factors, III, X.
Light gun signals — AIM 4-3-13
NOTAMs
| Type | What it covers |
|---|---|
| D (Domestic) | Runway/taxiway closures, NAVAID outages, lighting, airport services |
| FDC | Flight Data Center — regulatory: TFRs, IAP amendments, special instructions |
| Pointer | Cross-references another NOTAM |
| Military | Military bases |
| International (ICAO) | Outside US |
Always check via 1800wxbrief.com or your EFB. NOTAMs are a 91.103 preflight requirement.
Wake turbulence — AIM 7-3
- Generated by lift production — strongest when aircraft is heavy, slow, clean configuration
- Sinks behind and below the wingtips; descends ~400–500 fpm; usually levels 900 ft below flight path
- Drifts with the wind
Avoidance:
- Landing behind a heavy: stay above their glide path, land beyond their touchdown point
- Departing behind a heavy: rotate before their rotation point, climb above their flight path
- Crossing behind: cross above or upwind
- Helicopter wake: in forward flight, comparable to a fixed-wing of similar weight; while hovering, intense downwash
ADM — mnemonics
- P Pilot (IMSAFE, currency, experience)
- A Aircraft (airworthy, equipped, fueled)
- V enVironment (weather, terrain, airport, lighting)
- E External pressures (get-there-itis, schedules, ego)
- I Illness
- M Medication
- S Stress
- A Alcohol
- F Fatigue
- E Emotion / Eating
- P Plan
- P Plane
- P Pilot
- P Passengers
- P Programming (avionics, automation)
- P Perceive the hazard
- P Process the level of risk
- P Perform risk management
Hazardous attitudes (5): Anti-authority, Impulsivity, Invulnerability, Macho, Resignation. Each has a verbal antidote.
Aeromedical — AIM Ch 8
| Hazard | Cause | Recognition | Response |
|---|---|---|---|
| Hypoxia (hypoxic) | Low partial pressure of O₂ at altitude | Tingling, euphoria, blue lips, drowsiness, poor judgment | O₂, descend below 10,000 MSL |
| Hypoxia (hypemic) | CO poisoning, anemia, smoking | Headache, blurred vision | Vent cabin, off heat, O₂, descend, land |
| Hyperventilation | Stress, anxiety — exhaling too much CO₂ | Rapid breathing, dizzy, tingling, light-headed | Slow breathing; talk; breathe into bag |
| Spatial disorientation | Loss of visual reference (IMC, night, haze) | Leans, graveyard spiral, somatogravic illusion | Trust instruments, transition to instruments |
| Motion sickness | Inner ear vs visual mismatch | Nausea, cold sweat | Fresh air, focus on horizon, avoid heavy meals |
| Scuba flying | Nitrogen bubbles in joints | The bends — joint pain | Wait 12 hr after nondecompression / 24 hr after decompression dive before flight to 8,000 MSL; 24 hr regardless above 8,000 |
Visual illusions — landing
- Wider runway than usual: illusion of being too low → tendency to flare high → hard landing
- Narrower runway: illusion of being too high → flare low → land short
- Upsloping runway: appears higher than actual → may land short
- Downsloping runway: appears lower than actual → may overshoot
- Featureless terrain / black hole approach: appears higher than actual → flies a low approach
- Rain on windscreen: runway appears lower → may flare high
- Atmospheric haze: distance appears greater → flies high approach
When things go wrong
PIC emergency authority, NTSB 830 reporting, lost comm, transponder codes. Easy points often botched. ACS Area X.
PIC emergency authority — 91.3(b)
This is the single most important rule in 91. It is your shield. You don't need permission to do what's safe.
Transponder codes
| Code | Meaning |
|---|---|
| 1200 | VFR default (squawk on initial check) |
| 7500 | Hijack |
| 7600 | Lost comm (radio failure) |
| 7700 | Emergency |
Lost communication — VFR
- Squawk 7600
- Stay VFR. Land as soon as practicable at a suitable airport.
- At a tower-controlled airport: enter pattern from above, look for light gun signals.
- Day: rock wings as ack. Night: blink landing/nav lights as ack.
ELT — 91.207
- Required on most US-registered aircraft (some exceptions: training within 50 NM of base, etc.)
- Inspect within 12 calendar months
- Replace battery after 1 hour cumulative use OR when 50% of useful life expires
- Test only during the first 5 minutes of each hour (so SAR doesn't think it's real)
- May be removed for repair / replacement up to 90 days; placard "ELT not installed"
- 406 MHz preferred (digital, satellite, GPS-encoded); 121.5 MHz legacy
NTSB 830 — what's reportable
Two categories: Accident (always reportable, immediately) and Listed Incident (always reportable). Everything else is non-reportable unless NTSB requests.
Aircraft accident definition
Occurrence associated with operation of an aircraft, from boarding to deplaning, where:
- A person suffers death (within 30 days of accident), OR
- A person suffers serious injury, OR
- Aircraft receives substantial damage
| Term | Definition |
|---|---|
| Serious injury | Requires hospitalization >48 hrs (within 7 days); OR fracture of any bone (except simple fractures of fingers, toes, or nose); OR severe hemorrhage, nerve/muscle/tendon damage; OR injury to internal organ; OR 2nd or 3rd degree burns over >5% of body |
| Substantial damage | Damage that adversely affects structural strength, performance, or flight characteristics — normally requiring major repair or replacement. Excludes: engine failure or damage limited to an engine, bent fairings/cowling, dented skin, small punctures, ground damage to rotor or propeller blades, damage to landing gear/wheels/tires/flaps/engine accessories/brakes/wingtips |
Listed incidents — always reportable
- Flight control system malfunction or failure
- Crewmember unable to perform normal duties due to injury or illness
- Failure of a structural component of a turbine engine (excluding compressor/turbine blades and vanes)
- In-flight fire
- Aircraft collision in flight
- Damage to property other than the aircraft > $25,000
- For large multi-engine: in-flight evacuation slide deployment; airframe icing; engine failure resulting in shutdown
- Release of all or a portion of a propeller blade from an aircraft (excluding from groundings)
- Aircraft is overdue and believed to have been involved in an accident
Reporting timeline
| Event | Notification | Written report |
|---|---|---|
| Accident | NTSB immediately, by phone | Within 10 days (Form 6120.1) |
| Listed incident | NTSB immediately, by phone | Only if requested |
| Overdue aircraft (still missing) | NTSB immediately | Within 7 days |

Top traps and cross-cutting orals
The questions that don't fit cleanly in one phase. Memorize these and you've front-run 80% of DPE gotchas.
Top 20 gotchas
| # | Gotcha |
|---|---|
| 1 | Three different definitions of "night": logging (61.51) = civil twilight; currency (61.57) = SS+1 to SR−1; lights (91.209) = SS to SR. |
| 2 | Day passenger currency allows touch-and-goes. Night requires full-stop landings. |
| 3 | Cost sharing limited to fuel, oil, airport expenditures, rental — nothing else. Plus common purpose. |
| 4 | "High performance" = engine >200 HP strictly. Not 200 exactly. "Complex" = retract + flaps + CS prop, all three. |
| 5 | Two-way radio "established" requires ATC use of your callsign. "Aircraft calling, standby" doesn't count. |
| 6 | VFR mins jump at 10,000 MSL regardless of class — 5 SM / 1000 / 1000 / 1 SM. |
| 7 | Special VFR is day only unless instrument-rated AND aircraft IFR-equipped. |
| 8 | Fuel reserve: 30 min day, 45 min night, at normal cruise. Not approach. |
| 9 | Right of way descending order: distress → balloon → glider → airship → tow/refuel → powered. Powered is lowest. |
| 10 | 91.3(b) lets PIC deviate from any rule of Part 91 in an emergency. Written report on request, not automatic. |
| 11 | Substantial damage excludes engine, propeller, landing gear, wing tips, fairings, cowling. Easy way to think: if the airframe is intact, it's probably not substantial. |
| 12 | O₂ rules: 12,500–14,000 MSL crew if >30 min · 14,000+ crew continuous · 15,000+ passengers provided. |
| 13 | Mode C veil = 30 NM from Class B primary, surface to 10,000 MSL. ADS-B Out required wherever Mode C is. |
| 14 | Cruise altitudes apply only above 3,000 AGL. Below that, no hemisphere rule. |
| 15 | 91.119 minimum altitudes have an "except for takeoff and landing" carve-out. Engine failure falls under 91.3(b). |
| 16 | Annual is 12 calendar months. So is ELT inspection. Transponder and altimeter are 24 cal months. |
| 17 | BFR ≥ 1 hr ground AND ≥ 1 hr flight. Not "1 hour total." Both minimums apply. |
| 18 | ARROW = required on board. The radio station license is only required for international flights. |
| 19 | 61.53 self-grounding applies even under BasicMed, even with no medical issued, if you know you have a disqualifying condition. |
| 20 | Logbook is not required to be carried by a PPL (61.51(i)) — except to show a specific endorsement needed for the operation. |
Cross-cutting mock oral
Aircraft (91.203, 91.205, 91.207, 91.213, 91.409, 91.413): ARROW docs on board. ATOMATOFLAMES for day; FLAPS components for return-after-dark (position lights, anti-collision, source of power, spare fuses or CBs, landing light if for hire). Annual, transponder, ELT all current. Maintenance logs reviewed.
Environment (91.103): NWKRAFT — NOTAMs (incl. TFRs), weather (departure, en route, destination, alternate), known delays, runway lengths, alternates, fuel, T/O & landing distance per POH/W&B.
Flight plan (91.151, 91.155, 91.159): Westbound 270° at 6,500 MSL — even thousand + 500, legal. Eastbound 090° at 3,500 MSL — wait, 090° is 0–179°, needs odd thousand + 500 → 3,500 works. Fuel for trip + 45 min reserve (planning the after-dark leg). VFR mins en route — 3 SM, 500/1000/2000 in Class E below 10k.
External pressures (PAVE): Schedule pressure? Get-there-itis? Passengers expecting on-time arrival? I budget a divert option.
- Confirm the legal framework (61, 91, NTSB 830)
- Confirm the aircraft is airworthy and properly equipped
- Confirm the environment is within your personal limits
- Confirm you have an out — alternate, divert, abort criteria
- Confirm you have authority under 91.3(b) if it all goes sideways
