DGCA RTR(A) Part 1 cheat sheet

Radio Telephony Regulations and Licensing (RTR Rules, 2025)

• RTR(A) is the aeronautical radio telephone licence for aircraft station operators; it is issued under the RTR Rules, 2025 and is distinct from the RTR(C) or RTR(G) categories.

• The licence authorises operation of radio apparatus on an aircraft station; it does not authorise ground station or aeronautical broadcast operation.

• A candidate must pass the Part 1 (written) examination and the Part 2 (practical) test to be granted the licence; both are required.

• The licence is valid for the period specified in the Rules (commonly five years) and must be renewed before expiry; renewal requires the prescribed application and fee.

• Radio communication must be in standard ICAO phraseology; plain language is used only when standard phraseology is inadequate, and must be clear and unambiguous.

• The licence holder is responsible for maintaining radio discipline: no unnecessary transmissions, no profanity, and no unauthorised use of the frequency.

• Licence details must be produced on demand to an authorised officer; operating without a valid licence is an offence under the Rules.

• Examination content covers RT procedures, ATC communications, equipment operation, and the regulatory framework; the Part 1 pass mark is set by the licensing authority.
