Iran CAO ATCO Theory study plan

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

8 weeks · About 6 hours per week

Week 1

Air Traffic Management & Air Traffic Control Equipment and Systems

  • Define separation minima (longitudinal, lateral, vertical) and list the conditions for applying each in en-route and approach control.

  • Explain the principles of radar, primary/secondary surveillance, and transponder modes (A/C/S) and their operational use.

  • Identify the components of a typical ATM system (flight data processing, surveillance data processing, controller working position) and their functions.

  • Describe the differences between procedural and radar control and the associated equipment requirements.

  • List the ICAO documents (Doc 4444, Doc 7030) that specify separation and equipment standards.

Your checkpoint

Create a one-page separation minima cheat sheet with vertical, lateral, and longitudinal minima and the conditions for each, plus a table of surveillance equipment (PSR, SSR, Mode S) with key parameters.

Week 2

Air Traffic Management & Operational Procedures and Emergency Handling

  • Apply sequencing and spacing techniques (speed control, vectoring, holding) to arrival and departure flows in a simulated scenario.

  • Outline the actions for handling an aircraft emergency (radio failure, medical emergency, unlawful interference) according to ICAO procedures.

  • Describe the process for establishing and maintaining separation during an emergency descent.

  • Explain the purpose and content of an ATS incident report and the difference between an incident and an accident.

  • List the priority order for handling different types of emergencies (distress, urgency, etc.).

Your checkpoint

Write a 1-page emergency checklist covering radio failure, medical emergency, and unlawful interference, including initial actions, communications, and coordination with adjacent units.

Week 3

Air Law and ICAO Regulatory Framework & Aviation English and Phraseology

  • Summarize the key provisions of the Chicago Convention, including annexes relevant to ATM (Annex 2, 11, 10).

  • Explain the roles of ICAO, national authorities (e.g., CAO Iran), and service providers in regulation and oversight.

  • Demonstrate standard radiotelephony phraseology for routine clearances, read-back, and position reporting.

  • Identify common phraseology errors and correct them using ICAO standard phraseology.

  • Describe the licensing and rating requirements for air traffic controllers under Annex 1.

Your checkpoint

Record a 5-minute simulated radiotelephony exchange (clearance delivery, ground, tower) using standard phraseology, and self-assess against a checklist of 10 phraseology items.

Week 4

Meteorology & Navigation

  • Interpret METAR and TAF reports, including decoding abbreviations and identifying significant weather phenomena.

  • Explain the formation and hazards of thunderstorms, icing, and turbulence, and their impact on ATC operations.

  • Describe the types of navigation aids (VOR, DME, NDB, ILS, GNSS) and their principles of operation.

  • Interpret aeronautical charts (en-route, approach) and extract relevant navigation information.

  • Calculate basic navigation parameters (heading, track, wind correction angle) using the triangle of velocities.

Your checkpoint

Complete a 10-item weather and navigation exercise: decode 3 METARs and 2 TAFs, identify hazards, and solve 5 navigation problems (e.g., wind correction, GS calculation). Score at least 80%.

Week 5

Aircraft General Knowledge & Communications and Radio Telephony

  • Describe aircraft categories (wake turbulence categories) and their impact on separation minima.

  • Explain the effects of wake turbulence and strategies to avoid it (e.g., spacing, altitude separation).

  • Identify aircraft performance characteristics (climb/descent rates, speeds) relevant to ATC sequencing.

  • List the frequencies and frequency bands used in ATC communications (VHF, UHF, HF) and their propagation characteristics.

  • Explain the purpose of SELCAL and emergency frequency (121.5 MHz).

Your checkpoint

Produce a table of wake turbulence separation minima (in nautical miles) for arrivals and departures for all aircraft category pairs (Heavy, Medium, Light) as per ICAO Doc 4444, and a short note on frequency usage.

Week 6

Human Factors and Performance & Operational Procedures and Emergency Handling

  • Explain the SHELL model and its application to ATC human factors.

  • Identify common human errors in ATC (e.g., memory lapses, communication failures) and mitigation strategies (e.g., read-back, checklists).

  • Describe the effects of fatigue, stress, and workload on controller performance and countermeasures.

  • Apply situational awareness and decision-making models to a case study of an ATC incident.

  • Outline the components of an SMS (Safety Management System) and just culture principles.

Your checkpoint

Write a 300-word analysis of a real or hypothetical ATC incident, identifying human factors (SHELL) and proposing preventive measures. Include at least three references to human performance concepts.

Week 7

Air Traffic Control Equipment and Systems & Communications and Radio Telephony

  • Describe the operation and limitations of primary and secondary radar, including range, accuracy, and update rates.

  • Explain the purpose and function of Mode S, ADS-B, and multilateration in modern ATM.

  • Identify the components of a voice communication system (VCS) and backup systems.

  • Demonstrate proper radio discipline and emergency communication procedures (distress, urgency, radio failure).

  • Explain the impact of equipment failure on ATC operations and degraded modes.

Your checkpoint

Create a system diagram of a typical ATC surveillance and communication chain from radar/ADS-B to controller display, labeling each component and its failure modes. Include a 1-page summary of backup procedures.

Week 8

Air Law and ICAO Regulatory Framework & Air Traffic Management & Meteorology & Navigation & Aircraft General Knowledge & Human Factors and Performance & Communications and Radio Telephony & Air Traffic Control Equipment and Systems & Operational Procedures and Emergency Handling & Aviation English and Phraseology
