What's inside PLVACC Wiki

  1. Overview of Polish vACC (PLVACC) organization

    Polish vACC (PLVACC) is an informal organization for virtual aviation enthusiasts operating as a subdivision of the European division (VATEUD) within the EMEA region of the VATSIM network. It consists of both pilots and controllers. The rights and obligations of members are defined in the Polish VACC Policy.

  2. Overview of PLVACC training programs and certifications

    PLVACC offers several training paths. Programs ending in a CPT (Certified Proficiency Test) for VATSIM ratings include: S2 (Tower), S3 (Approach), and C1 (Area). Programs ending in an OTS (On-the-Job Training Session) for local PLVACC endorsements include: S2-PE (Procedural), S2-CE (Chopin), S3-CE (Chopin), and C1-CE (Chopin). Training sessions are recommended to take place in dedicated Discord rooms named 'Szkoła Kontrolerów - Training Room X'.

  3. Overview of Airspace Classes A and B in Poland

    While defined in general aviation standards, Class A and Class B airspace are currently not designated in Polish airspace.

    • Class A: IFR only, full ATC separation, clearance required.
    • Class B: IFR and VFR, full ATC separation for all, clearance required.

  4. Overview of Air Traffic Management (ATM) Structure

    Air Traffic Management (ATM) is a dynamic, integrated system designed to ensure the safe, economical, and efficient movement of aircraft. It consists of three primary components:

    1. Airspace Management: Responsible for the overall design of the airspace where aviation operations take place.
    2. Air Traffic Flow Management (ATFM): Monitors traffic density in designated airspaces to prevent ATC sector overloading.
    3. Air Traffic Services (ATS): Provides operational oversight of current aviation operations.

  5. Principles of Airspace Management (ASM)

    Airspace Management (ASM) involves designing and managing airspace elements to balance the competing requirements of different users:

    • Airlines: Require strictly regulated, safe, and efficient airspace with direct routes for business viability.
    • General Aviation: Prefer broad, unrestricted access to airspace and simplified flight planning with fewer restricted zones.
    • Military: Require regular access to large, exclusive reserved zones for maneuvers incompatible with civil traffic (e.g., high speed, low altitude, or weapons use).

    To achieve this, ASM uses 'flexible airspace management,' combining permanent elements (e.g., TMA Warszawa) with periodically activated structures such as conditional airways or temporary zones for airshows and military exercises.

  6. Responsibilities of a Tower Controller (TWR)

    The Tower Controller (TWR) is responsible for the safe, orderly, and efficient flow of air traffic within the airport area and its immediate vicinity. Primary responsibilities include:

    • Managing operations on and near the runway.
    • Controlling air traffic within the airport's controlled airspace (CTR).
    • Selecting the active runway.
    • Publishing and updating ATIS information.
    • Issuing clearances for runway occupancy and operations.
    • Ensuring required separation and traffic organization during airport and CTR operations.
    • Providing traffic information according to regulations.
    • Providing Delivery (DEL) and Ground (GND) services based on the 'top down' principle if those positions are unmanned.
    • Coordinating with other air traffic control positions.

  7. Virtual Airlines (VA) in Polish virtual airspace

    Virtual Airlines on VATSIM can be either based on real-world airlines or be entirely fictional. Pilots of virtual airlines are treated the same as other users on the network, but membership allows for group flights and enhanced simulation of real operations. PLVACC collaborates with virtual airlines during specific events. Examples of virtual airlines operating in Polish airspace include Cassubian (CSB), PAFFSair (PFF), Walker Air (WAT), LEIPZIGAIR (LHA), and French Flying Club (FVT).

  8. Understand ATC Transmission Types (Clearances, Instructions, Information)

    According to ICAO Doc 4444 (PANS-ATM), ATC communications are divided into three primary categories. Distinguishing between these is critical as it determines how the pilot must execute the action and whether a readback is required:

    1. ATC Clearances: Formal authorizations for an aircraft to proceed under specified conditions. These are not mere 'agreements' but legal authorizations defining what can be done, under what conditions, and up to which point.
    2. ATC Instructions: Directives requiring a pilot to take a specific action (e.g., changing heading or altitude).
    3. ATC Information: Data provided to assist the pilot (e.g., weather, QNH, traffic) that does not authorize or mandate a specific maneuver.

  9. Understand the relationship between TAS, GS, and Wind Correction

    Flight navigation involves calculating the relationship between different velocity vectors to maintain a desired path:

    • TAS (True Airspeed): The actual speed of the aircraft relative to the air it is flying through.
    • GS (Ground Speed): The actual speed of the aircraft relative to the ground. This value determines the estimated time of arrival (ETA).
    • Wind Correction: When wind blows from the side, a pilot must adjust the Heading (HDG) to compensate for drift and maintain the planned Track (TRK).

    In modern aircraft, these calculations are automated by the FMS (Flight Management System) and GNSS receivers.

  10. Understand the VATSIM organizational hierarchy

    VATSIM operates on a hierarchical structure where national organizations (sub-divisions) are nested within larger divisions and regions. The highest authority is the Board of Governors (BoG), whose powers are defined in the Code of Regulations (CoR).

    VATSIM is divided into three main regions: Americas, Asia Pacific, and Europe, Middle East, Africa (EMEA). Within EMEA, the primary divisions include:

    • VATEUD (European Division): Covers most European countries.
    • VATUK (UK Division): Covers the United Kingdom.
    • VATRUS (Russian Division): Covers Russia and Belarus.
    • VATIL (Israel Division): Covers Israel.
    • VATMENA (Middle East & North Africa Division): Covers the Gulf states, Middle East, and North Africa.
    • VATSSA (Sub-Sahara Africa Division): Covers Sub-Saharan Africa.

    Sub-divisions (such as Polish vACC / PLVACC) must ensure their local rules are consistent with the rules of their parent division and region.

  11. Understand Instrument Approach Procedure (IAP) categories

    An Instrument Approach Procedure (IAP) is a set of predefined maneuvers performed using onboard instruments to guide an aircraft to a point where the pilot can safely land or execute a missed approach. IFR approaches are divided into three main categories based on the type of guidance provided: Precision Approach (PA), Approach with Vertical Guidance (APV), and Non-Precision Approach (NPA).

  12. Manage arriving aircraft operations at the Tower position

    The Tower controller is responsible for managing arriving traffic to ensure aircraft can land or perform other operations on a clear runway. Arrival operations include:

    • Full landing
    • Touch-and-go (landing and immediate takeoff)
    • Low approach (flying over the runway without landing)
    • Stop-and-go (full landing followed by takeoff from the remaining runway length)
    • Other operations where the aircraft crosses the runway threshold from the air.
