Section 090.01: Concepts
01.01 Associated Terms
- Define key ATS terms for stations and communication methods.
- Utilizes terms from the International Civil Aviation Organization (ICAO) and European Aviation Safety Agency (EASA).
- Professional radio language ensures pilots and ATS understand each other clearly.
ATS Terms for Stations
- Aerodrome control radio station: Station providing radio-communication between an aerodrome control tower and aircraft.
- Aircraft station: A mobile station in the aeronautical mobile service located on board an aircraft.
- AFTN communication station: Station in the aeronautical fixed telecommunication network.
ATS Communication Methods
- Air-ground communication: Two-way communication between aircraft and ground stations.
- Importance of learning terms and abbreviations noted for efficient communication.
Holding and Approach Terms
- Visual Flight Rules (VFR): Rules that apply in good weather; flight training often starts here.
- Instrument Flight Rules (IFR): Used in poorer weather; requires additional ratings.
- Understanding unique terms aids in safer flying operations.
090.02: General Operating Procedures
02.01 Transmission Standards
- Key elements for effective transmission include clarity and understanding.
- Radio alphabet required for accurate phonetic spelling of letters and numbers.
Transmission of Letters
- Use phonetic alphabet: A = Alpha, B = Bravo, C = Charlie, etc.
- Spell out names, service abbreviations, or ambiguous words.
Transmission of Numbers
- Single digits and headings: Pronounce each digit separately (e.g., “heading one eight zero”).
- Flight levels: Whole hundreds are pronounced as such (e.g., “flight level two hundred”).
Transmission of Time
- Use Coordinated Universal Time (UTC) when transmitting times (e.g., “time zero eight two three”).
Aerodrome Weather
- METARs: Routine reports on weather conditions released hourly.
- Key elements: wind direction, visibility, present weather, cloud amount/type, temperature/dew point, pressure values.
090.04: Voice Communication Failure
Action Required
- Steps following a communication failure must be precise to maintain safety.
- First check radio settings; attempt to re-establish communication on other channels.
- Use transponder code 7600 for indicating radio failure.
090.05: Distress and Urgency Procedures
Distress Signals
- Defined as a condition requiring immediate assistance. Signals include the term
