Current DGCA framework

What changed for RTR candidates?

The current certificate and licence rules and the related DGCA CAR place the examination, certificate and licence process within the DGCA framework. The CAR is dated 27 November 2025 and effective from 1 December 2025.

Written + practical

Candidates generally need to pass both parts unless an applicable written-exam exemption is granted.

Computer number

A candidate needs a Computer Number from the Central Examination Organisation for the RTR examination process.

Official portals

Application and current notices are published through DGCA/Pariksha and the applicable eGCA process.

Written syllabus

What to study for RTR

The current DGCA CAR syllabus is grouped into Regulations and Procedure, Radio Principles and Practice, and Radio Telephony.

Regulations & procedure

Radio Regulations, Q codes, abbreviations, distress and urgency procedure, spelling, licensing, aircraft radio equipment, Indian FIRs and facilities, meteorological codes and NOTAM-related knowledge.

Radio principles & practice

Electrical units, wavelength and frequency, propagation, fading, HF communication, aircraft communication systems, radio navigation aids, microphones, headsets, squelch, tuning, simplex/duplex and interference.

Radio telephony

Transmission technique, letters, numbers and time, standard words and phrases, call signs, clearances and read-backs, flight levels and position reports, aerodrome, approach and area control phraseology, distress, urgency and communications failure.

Practical preparation

Prepare for the practical, not just the MCQs

The DGCA guidance for RTR practical training describes a simulated environment covering normal flight phases, traffic coordination, distress and urgency scenarios, varying routes and airfield layouts, weather and traffic variables, and voice/CRM interactions. Practise standard phraseology aloud and focus on clear, correct transmission and read-back habits.

Certificate & licence

What happens after the practical exam?

After passing the practical examination, the candidate can apply for the RTR Certificate and Licence through eGCA after paying the applicable fee. The CAR also preserves the validity of certificates and licences issued under the earlier 1954 rules. For licence extension beyond age 80, the CAR provides for yearly extension on the required experience evidence, subject to the stated conditions.

Apply after passing

Use the applicable eGCA process and pay the required fee after the practical examination.

Legacy licences

Certificates and licences issued under the earlier 1954 rules continue to remain valid under the current framework.

Extension after 80

The CAR provides for yearly extension beyond age 80 when the stated experience condition is met and the licence is not suspended or cancelled.

Use official information for licensing decisions

DGCA requirements, fees, examination sessions, application steps and licence procedures can change. CPLGrid's RTR guide is for preparation and general guidance; always check the latest official DGCA and Pariksha notices before applying.

Study guide

Prepare for RTR knowledge and practical communication

RTR preparation combines rules and radio principles with disciplined phraseology. Practise understanding a message, transmitting it accurately, reading back required items and responding clearly under simulated workload.

Regulations and procedure

Revise call signs, priorities, distress and urgency, clearances, read-backs, communication failure and applicable aeronautical radio procedures.

Radio principles

Understand frequency, wavelength, propagation, interference and the purpose and limitations of aircraft communication and navigation equipment.

Phraseology and read-back

Use standard phraseology, correct numbers and phonetics, and read back the items required by the applicable procedure. Avoid adding unnecessary words that obscure the message.

Practical scenarios

Practise ground, tower, approach and area-control exchanges as well as abnormal and emergency situations. Verify current examination details from DGCA/Pariksha notices.

Example concept check

What is the key purpose of a read-back?

Answer: To let the controller verify that critical instructions and clearances were received correctly.

Read back the items required by the applicable procedure, such as runway, level, heading or route instructions. If any part is unclear, request clarification rather than guessing.

What is the RTR written exam pattern?+

The DGCA CAR states that the written examination is an online computer-based theoretical knowledge examination of 50 multiple-choice objective questions, conducted in English.

What is the pass mark for the RTR written exam?+

The written examination pass mark is a minimum of 70%. A candidate who passes the written examination becomes eligible for the practical examination, subject to the applicable process.

What is the RTR practical exam?+

The practical examination is an approximately 30-minute simulated flight radiotelephony exercise in English. It assesses practical radio operation and procedure, sending and receiving messages, relevant regulations and aeronautical radio service provisions.

What is the RTR practical exam pass mark?+

The minimum passing mark for the practical examination is 50%.

How many attempts are allowed for the RTR practical exam?+

The current CAR provides a total of three practical examination attempts, subject to the validity of the written examination or applicable exemption. If all three practical attempts are failed, the candidate must reappear in the written examination before further practical attempts.

How long is the RTR written result valid?+

The written examination is valid for three years from the date of passing. An exemption from the written examination, where granted under the CAR, also has a validity of three years.

Can a candidate be exempted from the RTR written exam?+

The CAR lists specific categories that may be exempted, including certain qualified military or Coast Guard pilots with the required flying experience, holders of a valid legacy RTR certificate and licence under the 1954 rules, and holders of a valid Flight Radio Telephone Operator's Licence or equivalent issued by Commonwealth countries or the Philippines. The applicant must apply for exemption through eGCA and receive the grant before proceeding.

Does CPLGrid replace DGCA information?+

No. CPLGrid is a preparation platform. Examination dates, application procedures, fees, eligibility and licensing requirements can change, so candidates should verify current information on the official DGCA and Pariksha portals.
