This 100-question English four-option MCQ bank is a cross-rating study adaptation for IDAC's CTA licensing path under RAD 65. IDAC's public portal separates Spanish-language Aerodrome and Radar guides and includes true/false as well as multiple-choice study items. This bank is not an official translation or format simulation and cannot replace practical tower/radar training, supervised on-the-job experience, or radiotelephony assessment.

Sample IDAC Air Traffic Controller (CTA) Practice Questions

Try these sample questions to test your IDAC Air Traffic Controller (CTA) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under RAD 65 Subparte B, what is the fundamental scope and authority conferred by an Air Traffic Controller License (Licencia de Controlador de Tránsito Aéreo - CTA) issued by the Instituto Dominicano de Aviación Civil (IDAC)?

A.It authorizes the holder to exercise air traffic control functions only for those operational ratings and facility endorsements specifically endorsed on the valid license.

B.It authorizes the holder to provide unrestricted air traffic control at any Dominican civil or military airport without local facility endorsements.

C.It combines flight crew commercial piloting privileges with general aerodrome surface dispatch privileges throughout the Dominican Republic.

D.It serves as a permanent, non-expiring authorization to control all civil airspace regardless of medical currency or position checks.

Explanation: RAD 65 Subparte B establishes that a controller license is not an unrestricted pass to operate anywhere; the controller may only exercise privileges corresponding to valid ratings (e.g., Aerodrome Control, Approach Control, Area Control) and specific unit/facility validations, subject to medical currency.

2What is the minimum age required by RAD 65 to hold an Air Traffic Controller License (CTA) in the Dominican Republic?

A.21 years of age

B.18 years of age

C.23 years of age

D.25 years of age

Explanation: RAD 65 Subparte B aligns with ICAO Annex 1 standards by requiring an applicant for an Air Traffic Controller license to be at least 21 years of age (student controllers may begin structured ab-initio training earlier at certified academies such as ASCA).

3Under RAD 67 and RAD 65, which class of Aeronautical Medical Certificate (Certificado Médico Aeronáutico - CMA) is required for air traffic controllers in the Dominican Republic, and what is its standard validity for controllers under 40 years of age?

A.Class 3 (Clase 3), valid through the 36th month after the examination month

B.Class 1 (Clase 1), valid for 12 months

C.Class 2 (Clase 2), valid for 24 months

D.Class 3 (Clase 3), valid for 12 months

Explanation: The current RAD 61.23 medical-validity table lists air traffic controller privileges under a Class 3 certificate. When the medical examination occurs before age 40, the certificate is valid for that operation through the 36th month after the examination month; the table reduces this to 24 months from age 40 and 12 months from age 50.

4According to RAD 65.35, under what circumstance does an operational air traffic control rating (e.g., Aerodrome Control or Approach Control) cease to be valid?

A.If the controller ceases to exercise the privileges of that specific rating for a continuous period of 6 months or more.

B.If the controller fails to log at least 100 control hours every calendar month.

C.If the controller transfers to another control desk within the same facility for more than 14 consecutive days.

D.If the controller takes annual leave exceeding 30 consecutive calendar days.

Explanation: RAD 65.35 stipulates that an ATC rating becomes invalid if the controller ceases to exercise its privileges for 6 months or longer. To regain validity, the controller must undergo re-evaluation or requalification supervised by IDAC.

5Under Ley 491-06 de Aviación Civil and ICAO Annex 11, which of the following is NOT one of the five primary objectives of Air Traffic Services (ATS)?

A.To guarantee maximum commercial profitability and seat occupancy for scheduled air carriers.

B.To prevent collisions between aircraft in flight.

C.To prevent collisions between aircraft on the maneuvering area and between aircraft and obstructions on that area.

D.To expedite and maintain an orderly flow of air traffic.

Explanation: The five objectives of ATS are: (1) prevent collisions between aircraft, (2) prevent collisions on the maneuvering area, (3) expedite and maintain an orderly flow of traffic, (4) provide advice and information useful for safe and efficient flight (flight information service), and (5) notify search and rescue organizations (alerting service). Commercial profitability is outside the ATS safety mandate.

6Which of the following represents the correct list of air traffic controller ratings recognized under RAD 65 Subparte B in the Dominican Republic?

A.Aerodrome Control, Approach Control Conventional, Approach Control Surveillance/Radar, Area Control Conventional, and Area Control Surveillance/Radar.

B.Aerodrome Control, Flight Operations Officer, Aeronautical Station Operator, and Aircraft Maintenance Technician

C.Approach Control Conventional, Flight Information Service, Search and Rescue Coordinator, and Apron Control

D.Aerodrome Control, Approach Control Surveillance, Airline Transport Pilot, and Flight Instructor

Explanation: RAD 65 Subparte B establishes standard ratings matching ICAO Annex 1: Control de Aeródromo (Aerodrome Control), Control de Aproximación Convencional (Approach Control Conventional), Control de Aproximación Radar/Vigilancia (Approach Control Surveillance), Control de Área Convencional (Area Control Conventional), and Control de Área Radar/Vigilancia (Area Control Surveillance).

7According to RAD 91 and ICAO standards, what is the legal difference between an Air Traffic Control Clearance (autorización) and an Air Traffic Control Instruction (instrucción)?

A.A clearance authorizes an aircraft to proceed under specified conditions within controlled airspace, whereas an instruction directs a pilot to take a specific operational action (e.g., turn, climb, hold).

B.A clearance is an optional recommendation that pilots may disregard without notification, whereas an instruction is legally binding.

C.A clearance only applies to ground movements on the apron, whereas an instruction only applies to aircraft in cruising flight.

D.An instruction is issued exclusively by the military authority, whereas a clearance is issued by civil controllers.

Explanation: An ATC clearance authorizes flight along a route or under specific operational limits; an instruction is a mandatory directive requiring immediate or specified execution (such as 'climb to FL 240' or 'turn right heading 090') to maintain safety and separation.

8What is the minimum language proficiency requirement established by IDAC and ICAO for Dominican air traffic controllers providing ATS to international flights?

A.Operational Level 4 in English

B.Pre-operational Level 3 in English

C.Expert Level 6 in English and French

D.Elementary Level 2 in English

Explanation: Under ICAO Annex 1 and RAD 65, air traffic controllers providing service to international aircraft must demonstrate at least ICAO Operational Level 4 in English, requiring recurrent re-evaluation every 3 years (unless qualified at Level 6 Expert, which is permanent).

9Which entity within the Dominican state has the exclusive statutory authority under Ley 491-06 to establish, regulate, and supervise air navigation services and airspace architecture in the Dominican Republic?

A.Instituto Dominicano de Aviación Civil (IDAC)

B.Junta de Aviación Civil (JAC)

C.Comisión Investigadora de Accidentes de Aviación (CIAA)

D.Departamento Aeroportuario

Explanation: Under Ley 491-06, IDAC is the executive and technical authority responsible for civil aviation safety, regulation, personnel licensing, and air navigation service provision (ATS/CNS). The JAC handles commercial air policy and route agreements.

10When may a pilot-in-command deviate from an ATC clearance or instruction issued by a Dominican ATS facility, according to RAD 91?

A.Only in an emergency requiring immediate action, or in response to an Airborne Collision Avoidance System (ACAS/TCAS) Resolution Advisory (RA).

B.Whenever the pilot wishes to optimize fuel burn without informing ATC.

C.Any time flight visibility improves to greater than 10 km under IFR.

D.Whenever the copilot disagrees with the assigned cruising level.

Explanation: RAD 91.123 and ICAO rules require strict adherence to ATC clearances except in emergencies that necessitate immediate action to preserve life or aircraft safety, or when maneuvering to comply with a TCAS Resolution Advisory.
