Iran CAO ATPL Theory study plan

Iran CAO ATPL Theory · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Aircraft General Knowledge - Instrumentation & Navigation - General Navigation, Radio Navigation and Instrumentation

  • Map every instrument in the ATPL syllabus to its operating principle (pressure, gyroscopic, electrical, or magnetic) and draw a one-page schematic of each system

  • Explain the difference between direct-reading and remote-indicating instruments, and describe failure indications for each pitot-static instrument

  • Derive the relationship between indicated, calibrated, and true airspeed and solve ten numerical IAS-CAS-TAS-EAS conversion problems

  • Describe the principles of VOR, DME, and NDB including frequency bands, range, and the errors affecting each

  • Interpret a basic instrument approach chart in terms of the radio navigation aids it uses

Your checkpoint

A 15-page handwritten instrument and radio-navigation summary sheet with worked numerical examples and a labelled diagram of each system

Week 2

Aircraft General Knowledge - Instrumentation & Navigation - General Navigation, Radio Navigation and Instrumentation

  • Explain the operation of gyroscopic instruments (attitude indicator, heading indicator, turn coordinator) including rigidity and precession errors

  • Describe ILS components (localizer, glide path, markers, DME) and their tolerances, and explain how to fly a localizer and glide-path intercept

  • Solve problems on instrument lag, turning errors, and acceleration errors in the attitude and heading indicators

  • Describe GNSS architecture, RAIM, and the difference between RNAV and RNP specifications

  • Calculate a position fix from VOR radials and DME ranges on a chart

Your checkpoint

A timed 40-question self-test on instrumentation and radio navigation, scored and reviewed, with every wrong answer rewritten as a corrected note

Week 3

Aircraft General Knowledge - Airframe, Systems, Electrics, Powerplant and Emergency Equipment & Principles of Flight

  • Describe the airframe structure, load paths, and the purpose of primary and secondary flight controls

  • Explain the operation of hydraulic, pneumatic, electrical, and fuel systems including normal and abnormal indications

  • Describe piston and turbine engine principles, including the four-stroke cycle, thrust production, and engine limits

  • Explain the four forces of flight and how lift, drag, thrust, and weight change with angle of attack and airspeed

  • Derive the lift equation and explain the effect of density altitude on performance

Your checkpoint

A labelled systems diagram booklet covering airframe, hydraulics, electrics, fuel, and powerplant, plus a one-page lift and drag formula sheet

Week 4

Principles of Flight & Aircraft General Knowledge - Airframe, Systems, Electrics, Powerplant and Emergency Equipment

  • Explain stability (static and dynamic, longitudinal, lateral, directional) and the effect of centre of gravity on stability

  • Describe stall and spin aerodynamics including the critical angle of attack, stall speed factors, and recovery technique

  • Explain the effect of flaps, slats, and spoilers on lift and drag

  • Describe emergency equipment, fire detection and suppression, and oxygen systems

  • Explain asymmetric flight, rudder forces, and the effect of a failed engine on control

Your checkpoint

A closed-book written test of 30 questions on principles of flight and aircraft systems, achieving at least 75 percent

Week 5

Air Law and ATC Procedures & Operational Procedures

  • Describe the structure of ICAO Annexes and the applicability of Iranian civil aviation regulations to flight operations

  • Explain rules of the air: right-of-way, cruising levels, minimum safe heights, and VFR/IFR separation

  • Describe ATC clearance, readback requirements, and position reporting procedures

  • Explain operational procedures for normal, abnormal, and emergency situations, including depressurisation and engine failure

  • Describe the contents and use of the operations manual and the MEL

Your checkpoint

A written summary of air-law and operational-procedure rules with a 20-question self-test and a corrected answer key

Meteorology & Flight Planning and Flight Monitoring

  • Explain the structure of the atmosphere and the standard atmosphere, and calculate pressure altitude and density altitude

  • Describe the formation of clouds, icing, turbulence, and thunderstorms, and the hazards each presents to flight

  • Interpret METAR, TAF, and significant weather charts and decode a full set of sample reports

  • Prepare a full flight plan including fuel, alternate, and reserve calculations for a given route
