KCAA IR Theory study plan

KCAA IR Theory · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Instrument Flight Procedures and IFR Operations & Air Law and Kenya Civil Aviation Regulations

  • Map the KCARS instrument and IFR-related Parts (licensing, operations, airspace) and write a one-page cross-reference from each regulation to the operational procedure it governs.

  • Practise decoding 15 IFR clearances (SID, route, STAR, approach) by writing the readback for each and listing the required navigation performance for each segment.

  • Reconstruct the standard instrument departure and approach procedure design criteria (obstacle clearance, segment lengths, gradients) into a single annotated diagram of your own drafting.

  • Compare Kenyan airspace classes and IFR separation minima against ICAO Annex 2 and Annex 11 provisions, noting differences in a two-column table.

Your checkpoint

A one-page regulatory cross-reference sheet plus 15 written clearance readbacks, self-marked with corrections noted.

Week 2

Instrument Flight Procedures and IFR Operations & Air Law and Kenya Civil Aviation Regulations

  • Sequence the phases of an IFR flight (pre-flight, departure, en route, arrival, approach, missed approach) and state the pilot action and regulatory basis for each transition.

  • Calculate holding pattern entries and timing for 10 given inbound tracks, winds and altitudes, showing the entry type for each.

  • Explain the privileges, validity and recency requirements of the instrument rating under Kenyan licensing rules and list the documentation required on board.

  • Draft a personal checklist of the five most common IFR procedural errors and the mitigation for each.

Your checkpoint

A timed 20-question self-test on IFR procedures and air law, scored and reviewed with every wrong answer corrected in writing.

Week 3

Flight Planning and Monitoring & Radio Navigation

  • Build a full IFR flight plan for a 300 nm cross-country, including fuel computation, alternate selection and ETA derivation, and justify each figure used.

  • Compute true altitude, pressure altitude and density altitude for 10 airport scenarios and state the effect of each error on the flight plan.

  • Derive wind triangle solutions for 12 legs, converting between true, magnetic and compass headings using the published variation and deviation.

  • Explain the principles of VOR, DME, ILS and GNSS and describe the failure modes and monitoring actions for each.

  • Interpret a route chart and identify the minimum en-route altitudes, changeover points and required navigation performance for each segment.

Your checkpoint

A complete written flight plan with a navigation log showing heading, ground speed, ETA and fuel for every leg.

Week 4

Radio Navigation & Flight Planning and Monitoring

  • Solve 20 radio navigation problems covering VOR radials, DME slant range, ILS glideslope geometry and RNAV waypoint sequencing, showing the working for each.

  • Explain how GNSS augmentation and receiver autonomous integrity monitoring affect approach minima, and state the action required on a loss of integrity.

  • Recalculate the week 3 flight plan after injecting a 40 kt headwind and a 30-minute holding delay, and state the revised fuel and alternate decision.

  • Describe in-flight monitoring practice: how to detect a 5-degree tracking error, a fuel discrepancy and a late ETA, and the corrective action for each.

Your checkpoint

A 25-question radio navigation and flight planning test scored at 80 percent or better, with a written error log.

Week 5

Aircraft General Knowledge - Instruments & Meteorology

  • Draw and label the pitot-static and gyroscopic instrument systems from memory, naming each component and its failure indication.

  • Explain the causes, indications and pilot responses for 8 instrument failure modes, including pitot blockage, static blockage, gyro failure and altimeter mis-setting.

  • Interpret 12 METAR and TAF reports, decoding every group and stating the operational significance of each trend.

  • Read 6 significant weather and wind and temperature charts and derive the hazards relevant to an IFR flight at a stated level.

  • Describe the formation of icing, turbulence, thunderstorms and low-level wind shear, and state the avoidance and escape technique for each.

Your checkpoint

An instrument systems diagram set plus a decoded weather pack of 12 reports with a hazard summary for a chosen route.

Week 6

Meteorology & Aircraft General Knowledge - Instruments

  • Compute crosswind, headwind and tailwind components for 10 runway and wind combinations and state the personal and aircraft limits for each.

  • Derive freezing level, cloud base and visibility estimates from 8 temperature and dewpoint data sets and state the resulting IFR decision.

  • Explain the errors and limitations of the altimeter, airspeed indicator and attitude indicator in non-standard pressure, temperature and dynamic conditions.

  • Interpret 6 SIGMET and AIRMET style advisories and write the in-flight decision each would trigger.

Your checkpoint

A weather decision worksheet covering 10 scenarios, each with a go, no-go or divert recommendation and its justification.

Week 7

Human Performance and Limitations & Air Law and Kenya Civil Aviation Regulations

  • Explain the sensory illusions encountered in IMC (somatogravic, somatogyral, vestibular and visual) and the instrument cross-check technique that counters each.

  • Describe hypoxia, hyperventilation, carbon dioxide retention and decompression, including recognition, time of useful consciousness and corrective action.

  • State the fatigue, circadian and workload factors affecting instrument flight and apply a personal fatigue risk management plan to a night IFR sortie.

  • Relate the human performance requirements and duty limitations in Kenyan operations regulations to a sample 4-day roster.

  • Assess a case study of an IFR accident and identify the human factors chain and the regulatory and procedural barriers that failed.

Your checkpoint

A written human factors case analysis of at least 400 words linking the accident chain to specific limitations and mitigations.

Week 8

Air Law and Kenya Civil Aviation Regulations & Aircraft General Knowledge - Instruments & Flight Planning and Monitoring & Human Performance and Limitations & Meteorology & Radio Navigation & Instrument Flight Procedures and IFR Operations

  • Sit two full-length timed mock examinations under exam conditions and record the score by domain for each.

  • Re-study the two weakest domains identified by the mock results and rewrite the notes for those domains from memory.

  • Recite the key regulatory figures (validity periods, minima, fuel reserves, duty limits) from memory without reference.

  • Review the error log from weeks 1 to 7 and confirm that every previously wrong item can now be answered correctly with a stated reason.

Your checkpoint

Two completed mock exams with a domain-by-domain score sheet and a final one-page revision sheet.

Milestones

Week 2: Score at least 75 percent on the IFR procedures and air law self-test and show corrected answers for every missed item.

Week 4: Produce a complete flight plan that survives a wind and holding revision, and score at least 80 percent on the radio navigation test.

Week 6: Correctly decode 10 of 12 weather reports and justify a go or no-go decision for 8 of 10 scenarios.

Week 8: Score at least 80 percent overall on both mock exams with no domain below 70 percent.
