B02. International Telecommunication Convention, Radio Regulations And Definitions Quiz

Q1. In future, the traditional VHF voice band can be partly used for:

Intercontinental long range voice communications

Supporting next-generation satellite data links for air traffic management (ATM)

ILS Glide Path

Points to Remember – The traditional VHF aviation voice band operates between 118 and 137 MHz
– High congestion in this band is driving modernization strategies
– Segments of this spectrum will be repurposed for satellite-based data links
– These links support Air Traffic Management by prioritizing data throughput over voice channels

Q2. Which Indian publication deals with Communication Systems and Procedures in India?

Communication, Navigation & Surveillance (CNS) Manual Volume II

Aeronautical Information Publication (AIP) India

Aeronautical Information Circular (AIC) India

Points to Remember – The CNS Manual Volume II is the primary national publication for communication systems in India
– It outlines the standard operating procedures used within Indian airspace
– CNS stands for Communication, Navigation, and Surveillance

Q3. Working methods of ITU organs are defined in the:

Constitution of the ITU (1992)

The World Radio communication Conference (WRC-95)

Convention of the ITU (1992)

Points to Remember – The ITU uses two main documents: the Constitution and the Convention
– The Constitution outlines fundamental principles and high-level rules
– The Convention defines the operational rulebook and working methods of committees and organs

Q4. Satellite reception of ADS-B is on which frequency?

1087.7 – 1092.3 MHz

1.5/1.6 GHz

117.975 – 137 MHz

Points to Remember – ADS-B transponders transmit signals on 1090 MHz
– Low Earth orbit satellites capture these transmissions for global tracking
– The allocated frequency band for satellite reception is 1087.7 to 1092.3 MHz
– This frequency band is centered around 1090 MHz

Q5. Aeronautical Mobile (R) Service (AMRS), supporting airport surface communications and data links is:

Allocated spectrum in the 3 GHz band

Allocated spectrum in the 5 GHz band

Allocated spectrum in the 1.5 GHz band

Points to Remember – AMRS stands for Aeronautical Mobile Route Service
– Manages airport surface communication networks and critical safety data links
– Uses the 5 GHz spectrum band
– Supports high-speed data for surface movement guidance and next-gen airport systems
– Provides higher data rates compared to traditional VHF systems

Q6. ICAO DOC 9432 is a:

Air Traffic Management Manual

Manual of Communication

Manual of Radiotelephony

Points to Remember – ICAO DOC 9432 is the official Manual of Radiotelephony
– It establishes standardized global phraseology and transmission rules
– It is essential for theoretical aviation licensing exams like the DGCA RTRA

Q7. Aviation R/T Communication is governed by:

Convention of the ITU (1992)

DOC 9432 Manual of Radiotelephony

ICAO Annex 10, Volume II – Aeronautical Telecommunications

Points to Remember – Aviation R/T communications are officially governed by ICAO Annex 10 Volume II
– This annex contains the Standards and Recommended Practices (SARPs)
– ICAO DOC 9432 provides practical manual and guidance to support these standards

Q8. Which body implements policies framed by the I.T.U.?

D.G.C.A.

W.P.C.

A.A.I.

Points to Remember – The WPC is India’s national radio regulatory authority
– It operates under the Ministry of Communications
– It manages radio frequency spectrum within the country
– It implements international policies established by the ITU in India
