IDAC Air Traffic Controller (CTA) study guide
IDAC Air Traffic Controller (CTA) · Work through your exam, one topic at a time.
The IDAC Air Traffic Controller (CTA) licence is the credential issued in the Dominican Republic for professionals who provide air traffic control service - tower, approach, and area control - under the Instituto Dominicano de Aviación Civil. It is meant for candidates who have completed approved ATC training and now need to demonstrate, to the civil aviation authority, that they can apply the rules and procedures of the profession safely and consistently. The IDAC Air Traffic Controller (CTA) study guide has 9 sections and about 3,564 words.
01Air Law and Regulatory Framework
This domain tests whether you can place a real situation on the correct legal layer: the Chicago Convention and its Annexes, the PANS and regional supplementary procedures that add operational detail, and the Dominican structure in which IDAC regulates technically while the Junta de Aviación Civil handles economic matters. Expect scenarios asking which rule governs and whether it binds the operator.
382 words, about 2 min02Air Traffic Management
This is the largest operational domain: ATC services, flight rules, separation, ATS airspace and clearances. The exam asks you to apply Doc 4444 and Annex 11 to concrete traffic and pick the correct separation or clearance wording - not to recite definitions.
439 words, about 2 min03Meteorology
This domain tests decoding of METAR, TAF and trend information, correct altimetry, and recognition of hazardous weather with the ATS response it triggers. Questions are usually applied: a coded report, an altimeter question, or a weather situation requiring a SIGMET, an alert or a change of runway.
410 words, about 2 min04Navigation
This domain checks that you can read the charts controllers and pilots share, interpret radio navigation aid outputs, apply PBN/GNSS concepts, and handle position reporting. Questions often present a fix described by radial and distance, a chart minimum, or a report whose content must be assessed.
393 words, about 2 min05Aircraft and Principles of Flight
This domain tests the aircraft knowledge a controller needs: wake turbulence behaviour and categories, performance limitations that shape clearances, and basic principles of flight behind phrases such as "unable due performance". Wingtip vortices form whenever a wing generates lift; they are strongest when the aircraft is heavy, clean and slow - takeoff and early climb, and late final approach.
414 words, about 2 min06Communications
This domain tests standard radiotelephony, readback discipline, frequency management and ATS data link. Expect questions that pick the correct phraseology for a situation, identify a missing readback, or ask what to do when a data link or frequency fails.
376 words, about 2 min07Human Factors and Safety Management
This domain tests situational awareness, fatigue, teamwork and safety management as they appear on the position: why an experienced controller misses a conflict, how fatigue is managed, what just culture really means, and how an SMS functions beyond the manual. Three levels: perception of the traffic, comprehension of what it means, and projection of what will happen next.
368 words, about 2 min08Equipment and Systems
This domain tests the surveillance and automation that underpin radar control, and what you do when that equipment degrades. Questions ask how identification is established, what a safety net does, and which contingency procedure applies.
413 words, about 2 min09Operational Procedures and Emergency Handling
This domain tests what you do when something goes wrong: emergencies, alerting and search and rescue, unusual situations, and coordination with other units. Answers are judged on sequence and priority, not just on naming the right code.
