Study Notes

Phonetic Numbers and Their Uses

  • Phonetic numbers ensure clarity in communication, preventing misinterpretation.
  • Promotes uniformity in radio communications, as everyone uses the same phonetic terminology for numbers.
  • Enhances accuracy in understanding numerical information, crucial in high-pressure situations like piloting in adverse weather.

Phonetic Alphabet

  • ICAO recommends a standard phonetic alphabet for international aviation communications.
  • Examples include:
    • A - Alfa
    • B - Bravo
    • C - Charlie
    • Z - Zulu (designates military time)
  • Key numerical pronunciations:
    • Zero as "Ze-ro", One as "Wun", Two as "Too", Three as "Tree", Nine as "Niner", Decimal as "Day-see-mal".

Zulu Time

  • Zulu time, or Coordinated Universal Time (UTC), standardizes time globally, eliminating confusion between A.M. and P.M.
  • The Philippines operates at UTC+8, meaning 12:00 A.M. GMT corresponds to 8:00 A.M. locally.

Categories of Airspace

  • Airspace is classified into regulatory (Class A, B, C, D, E, G) and non-regulatory for organized traffic flow.
  • Special areas include restricted and prohibited airspace, military operation areas, and controlled firing areas.

Types of Airspace

  • Class B: Controlled airspace from ground to 10,000 feet MSL, requires two-way radio and a transponder.
  • Class C: Radar service provided, two areas (inner core and outer shelf) with specific visibility requirements.
  • Class D: Airports with ATC, requires two-way communication, extends to 2,500 feet AGL.
  • Class E: Controlled airspace with no specific requirements; entry generally requires radio communication.
  • Class G: Uncontrolled airspace with limited ATC involvement, often below 700 or 1,200 feet AGL.

VFR Weather Minimums

  • Standard minimums for VFR (Visual Flight Rules) include:
    • 3 statute miles visibility
    • Cloud clearance: 1,000 feet above, 500 feet below, 2,000 feet horizontally.

Transponder Operation

  • Transponders transmit identification codes to ATC, enhancing radar identification of aircraft flying under IFR (Instrument Flight Rules).
  • Squawk Codes: Specific four-digit codes provided by ATC to identify aircraft, indicating various statuses (e.g., emergency, radio failure).

Communication Fundamentals

  • Clear communication involves addressing the 4 W’s: Who you are calling, your identity, current location, and intentions.
  • Readability Scale: Ranges from 1 (unreadable) to 5 (perfectly readable) to assess transmission clarity.

Radar and ATC Services

  • Radar systems use radio waves to detect aircraft position and movement.
  • Transponder modes:
    • Mode A: Basic identification.
    • Mode C: Provides altitude information.
    • Mode S: Advanced, selective interrogation with multiple formats.

Critical Communication Practices

  • Strong emphasis on the importance of communication among pilots and ATC to ensure safety and prevent misunderstandings.
  • Use of phrases like "Say Again" for repetition and "Standby" for pausing conversations.
