Q

DGCA

A

(Directorate General of Civil Aviation):**

48
Q
  • **VOR (
A

VHF Omnidirectional Range):** A type of short-range radio navigation system for aircraft, allowing them to determine their position and stay on course by receiving radio signals transmitted by a network of fixed ground radio beacons.

49
Q
  • Doppler VOR:
A

An advanced type of VOR that uses Doppler shift principles to provide more accurate bearing information, particularly effective in reducing errors caused by ground reflections.

50
Q
  • **NDB-ADF (
    • NDB:
    • ADF:
A

Non-Directional Beacon and Automatic Direction Finder):**

A non-directional radio beacon that transmits signals in all directions, which aircraft can receive and use to determine their bearing relative to the beacon.

The Automatic Direction Finder is the aircraft equipment that receives NDB signals and displays the direction to the NDB station relative to the aircraft’s heading.

51
Q
  • **DME (
A

Distance Measuring Equipment):** A transponder-based radio navigation technology that measures the slant range (line-of-sight distance) between an aircraft and a ground station.

52
Q
  • **AFTN (
A

Aeronautical Fixed Telecommunications Network):** A worldwide system of aeronautical fixed circuits providing data exchange between civil aviation authorities, air traffic services, and other entities involved in aviation operations.

53
Q
  • **MWARA (
    • MWARA:
    • RADARA:
A

Major World Air Route Area) and RADARA (Regional and Domestic Air Route Area):**

A designated area over major international air routes where specific communication protocols and frequencies are used.

Similar to MWARA, but pertains to regional and domestic routes, often using different communication procedures suited to these areas.

54
Q
A

Wireless Planning & Coordination Wing):**

55
Q
  • Difference Between HF and VHF:
  • ## Why VHF is Used in Communication:
  • Range of VHF and HF Frequency:
  • Bandwidth:
A
  • HF (High Frequency): Ranges from 3 MHz to 30 MHz, with long-range communication capability due to its ability to reflect off the ionosphere (skywave propagation).
    • VHF (Very High Frequency): Ranges from 30 MHz to 300 MHz, used for short-range communication as VHF signals travel in a straight line and are generally limited to line-of-sight.

VHF is preferred in aviation communication because it provides clear and reliable voice communication within line-of-sight, has less atmospheric interference compared to HF, and is suitable for the short distances involved in most air traffic communication.

  • VHF: Effective range is typically 100-200 nautical miles (NM) depending on altitude and antenna height.
    • HF: Can be thousands of miles, depending on atmospheric conditions, as it can reflect off the ionosphere.
  • VHF Communication Bandwidth: Typically around 25 kHz or 8.33 kHz in regions where frequencies are more tightly spaced.
    • HF Communication Bandwidth: Varies depending on the application but is generally broader due to the need for long-distance communication.
56
Q
  • Single Side Band (SSB) vs. Double Side Band (DSB):
A
  • SSB: A type of amplitude modulation that uses only one sideband, reducing bandwidth and improving power efficiency.
    • DSB: Amplitude modulation that includes both the upper and lower sidebands, leading to greater bandwidth usage compared to SSB.
57
Q
  • ## Spacing Between Two VHF Frequencies:
A

Typically, 25 kHz, but in regions with crowded airspace, it can be reduced to 8.33 kHz to allow more channels within the same frequency range.

58
Q
  • **NDB (
A

Non-Directional Beacon):** A radio transmitter at a known location, used as an aviation or marine navigational aid. NDB signals follow the curvature of the Earth, so they can be received at low altitudes and over long distances.

59
Q
  • **CPDLC (
  • ## Frequency of CPDLC & NDB:Uses of CPDLC:
A

Controller-Pilot Data Link Communications):** A method of communication between an aircraft and air traffic control using data link messages instead of voice communication.

CPDLC typically operates over VHF (Very High Frequency) and SATCOM (Satellite Communication) depending on the region and specific system.

NDBs operate in the LF (Low Frequency) and MF (Medium Frequency) bands, typically between 190 kHz and 535 kHz.

  • Uses of CPDLC:
    • Reduces communication errors and radio congestion.
    • Provides clear and unambiguous messages.
    • Enables efficient communication in areas with poor VHF coverage, such as oceanic regions
60
Q
  • Distress Call:
A

The international radio distress signal is “Mayday,” used in life-threatening emergencies.

61
Q
  • **ILS (
A

Instrument Landing System):** A precision runway approach aid based on two radio beams which together provide pilots with both vertical and horizontal guidance during an approach to land.

62
Q
  • **TORA (
  • **TODA (
  • Runway and Stopway Difference:
A

Takeoff Run Available):** The length of runway declared available and suitable for the ground run of an airplane taking off.

Takeoff Distance Available):** The length of the takeoff run available plus the length of any clearway.

  • A Runway is a defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft.
    • A Stopway is an area beyond the takeoff runway, no less wide than the runway, and able to support an aircraft during an aborted takeoff without causing structural damage to the aircraft.
63
Q
  • **NOTAM (

.

A

Notice to Airmen):** A notice filed with an aviation authority to alert aircraft pilots of any hazards en route or at a specific location.

64
Q
  • Runway Lights:.
A

These include different types like edge lights, centerline lights, and touchdown zone lights, which guide pilots during landing and takeoff, especially at night or in low visibility

65
Q
  • Annex 10:
A

Refers to the ICAO (International Civil Aviation Organization) document on Aeronautical Telecommunications, detailing standards and recommended practices for communication, navigation, and surveillance systems.

66
Q
  • Difference Between Relative Bearing and Radial:
A
  • Relative Bearing: The angle between the direction to an object and the aircraft’s heading.
    • Radial: A line of position extending outward from a radio navigation aid (like a VOR), defined by the direction from the station.
67
Q
  • Homing:
A

Refers to the method of navigating toward a radio beacon or other navigational aid by adjusting heading to maintain a relative bearing of zero.

68
Q
  • Disadvantage of NDB:
A
  • Susceptible to atmospheric disturbances and signal interference.
    • Less accurate compared to modern navigation systems like VOR or GPS.
