Overview
This lecture provides a comprehensive summary of the FAA instrument rating requirements, procedures, and operational rules for IFR (Instrument Flight Rules) pilots, including flight planning, equipment, procedures, and key regulations.
Instrument Rating Basics
- Instrument time is logged when flying solely by reference to instruments under actual or simulated conditions (61.51g).
- Instrument rating required to act as PIC in IFR conditions, Class A airspace, certain cross-country ops, and for Special VFR at night.
- Must have a current medical and instrument rating to be PIC under IFR.
Experience & Currency Requirements
- 50 hours cross-country PIC time; 10 hours in airplanes.
- 40 hours instrument time, 15 with CFII; simulators/ATDs count with limits.
- 250 NM cross-country flight, 3 types of approaches, 3 hrs training in last 2 months.
- Instrument currency: 6 instrument approaches, holdings, intercept/tracking every 6 months (“6 HITS”); IPC if not current after 12 months.
Safety Pilot & Passenger Carrying
- Safety pilot must be rated in category/class, have current medical, and adequate visibility.
- 3 takeoffs/landings in last 90 days for passenger carrying; full stop for tailwheel/night ops.
Required Documents & Aircraft Equipment
- Pilot: certificate, medical, photo ID.
- Aircraft: ARROW (Airworthiness, Registration, Radio license (if international), Operating limitations, Weight/balance).
- Day VFR: “A TOMATO FLAMES”; Night: add “FLAPS”; IFR: “GRABCARD”.
- Required maintenance: annual, 100hr (if for hire), altimeter, transponder, ELT, etc., on set schedules.
Preflight & IFR Flight Planning
- Assess with IMSAFE, PAVE, DECIDE.
- Required info: NWKRAFT (NOTAMs, Weather, Known delays, Runway info, Alternatives, Fuel, T/O & Landing data).
- File IFR flight plan: online, with ATC, FSS, or electronically; preferred routes recommended.
IFR Operations & Procedures
- No IFR T/O mins for Part 91; other parts require mins based on number of engines.
- Departure/arrival procedures: ODP (obstacle), SID (standard), STAR; always follow CRAFT for clearance.
- Minimum IFR altitudes: 1,000 ft above obstacles (non-mountainous), 2,000 ft (mountainous), or MEA.
- Required reporting: missed approach, leaving a hold, nav loss, safety issues, etc.
Navigation, Charts, and Approaches
- MEA: Minimum Enroute Altitude; MOCA: Minimum Obstruction Clearance Altitude.
- Obey published altitudes, holding speeds, and position reporting outside of radar.
- Types of approaches: ILS, VOR, RNAV, LOC, NDB, ASR, LDA, SDF, PAR, etc.
Instruments & Equipment
- Gyroscopic: attitude, heading indicator, turn coordinator.
- Pitot-static: airspeed, altimeter, VSI; know errors and failure modes.
- Glass cockpits use AHRS, ADC, and integrate PFDs/MFDs; RAIM/WAAS for GPS integrity.
Lost Communications and Emergencies
- Altitude: fly highest of MEA, assigned, or expected.
- Route: AVEF (Assigned, Vectored, Expected, Filed).
- Remain predictable and comply with lost comms procedures.
Weather, Icing, and Hazards
- Know types/levels of icing, thunderstorm stages, and types of hydroplaning.
- Supplemental oxygen required above 12,500 ft (various crew/passenger rules).
ADS-B, Transponder, and Electronic Devices
- ADS-B required in Class A, B, C, above 10,000 ft MSL (exceptions apply).
- Transponder failures require ATC notification and possible deviation.
- Electronic devices limited onboard, with operator discretion for exceptions.
Key Terms & Definitions
- PIC — Pilot in Command.
- CFII — Certified Flight Instructor – Instrument.
- MEA — Minimum Enroute Altitude; ensures nav and obstacle clearance.
- MOCA — Minimum Obstruction Clearance Altitude; nav coverage up to 22 NM.
- IPC — Instrument Proficiency Check; required for lapsed currency.
- 6 HITS — 6 approaches, holds, intercept/track nav systems (IFR currency).
- GRABCARD — Acronym for required IFR equipment.
- IMSAFE — Illness, Medication, Stress, Alcohol, Fatigue, Emotion/Eating (pilot self-check).
- RAIM — Receiver Autonomous Integrity Monitoring; GPS signal integrity.
- WAAS — Wide Area Augmentation System; GPS accuracy enhancement.
Action Items / Next Steps
- Review acronyms (IMSAFE, PAVE, GRABCARD, 6 HITS, NWKRAFT).
- Ensure compliance with all logging and recency requirements.
- Study minimum required equipment and reporting procedures.
- Practice lost communications and holding procedures.
- Prepare required personal and aircraft documents before flight.
