-===Introduction===
-This Study Guide has been designed to give you all the information needed to start controlling as a Tower controller on the VATSIM network.
-===Radio Communication - Basics===
+The Study Guides are tutorial-like documents for the relevant steps in your training career. Study them step by step along with your trainings.
-Because Communication is crucially important for Air Traffic Control a fixed format and syntax us used, in order to minimize the risk of misunderstandings and to keep messages short. Worldwide English is the primary language in use, however in most countries you are also allowed to use the local language. In Austria VFR flights can choose their language whereas IFR flights are mostly conducted in English. Link: [[Buchstabiertabelle]]
-====Basic Rules====
-In order to achieve the goals set above the following rules important:
-#''Listen before you talk''
-#: It's impossible for two radio stations to transmit on the same frequency at the same time. If this is done, the radio signal will be blocked and this will result in a nasty noise on the frequency. Therefore it's important that every station monitors the frequency for about 5 seconds before transmitting, to make sure there’s no ongoing radio traffic. If you hear an ongoing conversation, wait until the conversation is over before you begin to transmit. Don’t start your communication if there is a read-back expected on the last transmission even if there is a short pause.
-#''Think before you talk''
-#: The radio traffic flow should be as smooth as possible. To achieve this it's vital to "think first" before transmitting so that a clear, concise and uninterrupted message can be sent.
-#''As far as possible use standard phraseology and syntax''
-#: To prevent misunderstandings and to maintain the radio traffic as effective as possible, stick to standardized phraseology and skip slang and of course private messages.
-====Callsigns and Initial Contact====
+*[[Study Guide:Intro]]
-Every participant on the network has his own Callsign. Controller Positions are identified by their location and their Function (e.g. Wien Radar, Graz Tower), Aircraft either by their Registration (e.g. OE-ALB) or an Airline Callsign followed by a combination of numbers and letters (e.g. AUA25LM, SWR387).
+*[[Study Guide:Basic Lesson]]
-To pronounce these letters and digits the ICAO-Alphabet is used.
+*[[Study Guide:Euroscope]]
-''
+*[[Study Guide:OBS]]
-To initiate the contact between two stations an initial call has to be made. This call has the following structure:''
+*[[Study Guide:Delivery]]
- '''Station 1:''' Station 2, Station 1, Message
+*[[Study Guide:Ground]]
- '''Station 2:''' Station 1, Station 2, Message
+*[[Study Guide:Tower]]
-''Example - Austrian 251 is calling Wien Tower:''
+*[[Study Guide: Approach]]
- '''AUA251:''' Wien Tower, Austrian 251, with you.
+*[[Study Guide:Radar]]
- '''LOWW_TWR:''' Austrian 251, Wien Tower, Servus!
+*[[Study Guide:Airport Details]]
-In Subsequent calls the calling station part can be ommited. <br>
+*[[Study Guide:Low Visibility Procedures]]
-When a controller (or aircraft) transmits a message to a station it is very important that the receiving station acknowledge the message and reads back any required parts.. If the receiving station does not acknowledge, the transmitted message is considered as a lost transmission and the sender should resend the message or check if the receiving station got the message.
+*[[Study Guide:Special Procedures]]
-Items that must always be read back in full are all clearances (including altitudes, heaings, speeds, radials etc), runway in use, altimeter setting (QNH or QFE) and transition level, and all frequencies. For a controller, this is extremely important to remember, since if a pilot's readback is incorrect, the controller has to ask for confirmation, i.e a new readback. There are also items that should not be read back to reduce unnesessary radio transmissions. In short, this includes everything not mentioned above, but a few examples are: wind, temperature and other weather information (except altimeter settings) and traffic information in detail.
+*[[Study Guide:Flight Level Allocation Scheme]]
-When giving an instruction the Callsign is stated at the beginning, when reading back you usually add it at the end of your transmission (although you are allowed to do it at the beginning too). <br><br>
+*[[Study Guide:Flight Information Center]]
-'''Examples:'''
- '''LOWW_APP:''' AUA251, turn left heading 290, descend to Altitude 5000 feet, QNH 1019.

-===How is an Aerodrome Organized?===
+*[[LOWI_Primer]] for Innsbruck
-Der '''TWR (Flugplatzkontrollstelle)''' ist zuständig für den :<br>
+*[[LOWW_Primer]] for Vienna (under construction)
- Flugplatzverkehr
- Personen und Fahrzeugverkehr auf Manövrierflächen
-Nachdem Follow-Me Fahrzeuge nicht mehr eingesetzt werden dürfen entfällt hier der zweite Punkt.<br>
-Die Flugplatzkontrollstelle kann nun auch weiter untergliedert werden in die Positionen Delivery (DEL), Ground/Rollkontrolle (GND) sowie Tower/Turm (TWR).<br>
-<br>
-Die nächst höher gelegene "Instanz" ist die '''APP (Anflugkontrollstelle)'''<br>
- Kontrollierte An- und Abflüge
-<br>
-Die Anflugkontrollstelle in Wien ist für An- und Abflüge zuständig und kann bei Bedarf sektorisiert werden. So kann man den LOWW_APP in jeweils einen Nord-Süd Sektor teilen, oder aber in einen Upper-Lower Sektor
-aufteilen. Zu Spitzenzeiten werden die Sektoren nach beiden Verfahren geteilt, noch dazu wird eine Director-Position eingerichtet, die LFZ vom Lower Approach auf das ILS führen.<br>
-<br>
-Darüber befindet sich die '''ACC (CTR) Bezirkskontrollstelle'''<br>
- Für alle übrigen kontrollierten Flüge
-Bei VATSIM bearbeitet der LOVV_CTR das gesamte Bundesgebiet und übernimmt auch die Tätigkeit des TWR & APP auf allen österreichischen Flughäfen, sollten diese nicht online sein. Das Gebiet Tirol & Vorarlberg
-über FL165 wird nicht von LOVV kontrolliert, sondern im Auftrag der ACG von der deutschen Flugsicherung mitbetreut (EDMM).<br>
->br>
-Alle drei Kontrollstellen üben den Kontrolldienst gemäß §68 Abs.1 LVR aus und erfüllen folgende Aufgaben:
- '''Sicherheit gewährleisten''' durch
-  Vermeidung von Zusammenstößen zwischen Luftfahrzeugen
-  Vermeidung von Zusammenstößen zwischen Luftfahrzeugen und Hindernissen auf den Manövrierflächen
- '''Wirtschaftlichkeit gewährleisten''' durch raschen, flüssigen und geordneten Ablauf des Verkehrs
-Diese Aufgaben gelten auch für den Controller in VATSIM, wenn auch aus anderen Beweggründen. In dem Wunsch so nahe an die Realität wie möglich zu kommen, sind diese Leitfäden unerlässlich.<br>
-===Working Delivery Positions===
+= Other related documents =
-Clearence Delivery is responsible for checking and correcting flightplans of departing aircraft.
-====Flightplan Structure====
-'''Flight plans''' are documents filed by pilots with the local Civil Aviation Authority prior to departure. They generally include basic information such as departure and arrival points, estimated time en route, alternate airports in case of bad weather, type of flight (whether instrument flight rules or visual flight rules), pilot's name and number of people on board.<br>
-For IFR flights, flight plans are used by air traffic control to initiate tracking and routing services. For VFR flights, their only purpose is to provide needed information should search and rescue operations be required.<br>
-<br>
-'''Routing Types'''<br>
-Aircraft routing types used in flight planning are: Airway, Navaid and Direct. A route may be composed of segments of different routing types.<br>
-<br>
-'''Airway'''<br>
-Airway routing occurs along pre-defined pathways called Airways. Mostly aircraft are required to fly airways between the departure and destination airports. The rules cover altitude, airspeed, and requirements for entering and leaving the airway (SIDs and STARs).
-<br>
-'''Navaid'''<br>
-Navaid routing occurs between Navaids (short for Navigational Aids) which are not always connected by airways. Navaid routing is typically only allowed in the continental U.S. If a flight plan specifies Navaid routing between two Navaids which are connected via an airway, the rules for that particular airway must be followed as if the aircraft was flying Airway routing between those two Navaids. Allowable altitudes are covered in Flight Levels.<br>
-<br>
-'''Direct'''<br>
-Direct routing occurs when one or both of the route segment endpoints are at a latitude/longitude which is not located at a Navaid.<br>
-====Issuing IFR Routing Clearances====
+* [[Squawk_Codes]]
-DEL gives routing clearances to all departing aircraft with the following information:<br>
+* [[Airspace classes]]
- '''Destination of aircraft'''
+* [[Emergency procedures]]
- '''SID''' (= Standard instrument departure) Normally the filed SID is given
+* [[Visibility ranges]]
- Initial climb altitude after departure (5000ft)
+* [[Radio Procedures for Controllers]]
- '''Squawk''' (Squawk assignments for LOWW are 4600 to 4620)
+* [[CPDLC Guide]]
- '''QNH''' (Local QNH of airport according to latest METAR)
+* [[Radar Identification]]
- CTOT (= Calculated take-off time) Slot time (Normally not used on the VATSIM network)
-The '''bold''' marked points are mandatory, all other points are optional.<br>
-<br>
-Normal construction of a routing clearence:
- Callsign, cleared to XXXX via XXXXX XX departure, (climb initially 5000ft), Squawk 46XX, QNH XXXX
-Example:<br>
- Austrian 125, cleared to Frankfurt via LUGIM 1C departure, climb initially 5000ft, Squawk 4601, QNH 1020.
-After a correct read-back of the pilot hand-off him to next higher position (i.e. GND)<br>
-====Special Situations (High Traffic, Slots, ...)====
-===Working Ground Positions===
-Ground is responsible for all movements of aircraft on ground, except the movements on the runway.
-Ground takes over responsibility for Delivery if he is not online.<br>
-<br>
-'''Start-up clearence'''<br>
-Start-up clearence can be given if no other aircraft is taxiing behind the starting-up aircraft and if the take-off is expected in 20 minutes or less.
- Austrian 125, start-up approved, (Temperature Minus 3)
-'''Push-back clearence'''<br>
-Push-back clearence can be given if no other aircraft is passing behind and the parking position requires push-back (i.e. position at the gate, … [refer to charts])
- Austrian 125, push-back approved”
-'''Combination of both phrases'''<br>
-During low traffic you can use these two phrases together<br>
- Austrian 125, start(-up) and push(-back) approved
-====Taxi Instructions====
-The easiest way giving taxi instructions to aircraft is to:<br>
- Taxi outgoing aircraft on taxiway MIKE (former OSCAR) ASAP.
- Taxi incoming aircraft on taxiway LIMA (former INDIA) ASAP.
-In this way, collision of aircraft should be avoided. Incoming aircraft on runway 16/34 vacating via B3 to B10 should use taxiway DELTA and LIMA (former INDIA).<br>
-====Ground Traffic Management====
-In case of a landing on runway 29 no aircraft is allowed to be in the extended runway centreline of runway 29 while landing aircraft is passing above. In this case aircraft should hold at ROMEO, FOXTROTT, SIERRA and GOLF and wait until the incoming aircraft touched down.<br>
-You can also advise aircraft to follow behind another aircraft or give way to other taxiing aircraft.<br>
- Austrian 125, follow Airbus 320 to holding-point runway 29
- Austrian 125, give way to taxiing Airbus 320 passing from left to right
-When an aircraft is approaching its assigned holding-point (and clear of possible traffic-conflict) a hand-off to next higher position (i.e. TWR) shall be initiated as soon as possible.<br>
- Austrian 125, contact Tower on 119.40
-'''Intersection take-off'''<br>
-Intersection takeoffs can be granted by GND in coordination with TWR and in accordance or on pilot’s request.<br>
-====Special Situations (High Traffic, Slots, ...)====
-===Working Tower Positions===
-Tower is responsible for all movements on the runways as well as for all movements within the control zone (CTR), (10NM radius, GND to 2500ft MSL).<br>
-Tower is also responsible for ground and delivery if they are not online. He also decides which runways are in use.
-====ATIS====
-Bei der ATIS (Automatic Terminal Information Service) handelt es sich um eine automatisch generierte Informationsdurchsage für den Flugverkehr an größeren Flughäfen. Sie wird auf einer eigenen Frequenz in einer Endlosschleife gesendet und soll die aktiven Funkstationen am Flughafen entlasten.<br>
-Piloten, die unter IFR an- oder abfliegen, sind verpflichtet, vor dem Erstkontakt mit der zuständigen Flugverkehrskontrollstelle zunächst das ATIS abzuhören. Beim Erstkontakt nennt der Pilot den ATIS-Kennbuchbuchstaben, um dem Controller zu bestätigen, dass er die aktuelle Version abgehört hat.<br>
-<br>
-'''Bestandteile einer ATIS Meldung:'''<br>
-* Name des Flughafens
-* Laufender ATIS-Kennbuchstabe
-* Zeit der Beobachtung des Flugplatzwetters
-* Aktive Landebahn
-* Übergangshöhe
-* Windrichtung und -geschwindigkeit
-* Flugsichten
-* besondere Wetterlagen (z.B. Regen)
-* Hauptwolkenuntergrenze
-* Temperatur und Taupunkt
-* QNH
-* Änderungstrend
-Die ATIS wird alle 30 Minuten oder bei signifikanten Wetteränderungen erneuert.<br>
-====Determination of active Runways====
-Pilots normally prefer to takeoff and land the aircraft with the nose into the wind because it shortens the Rwy length required to safely operate the aircraft. The wind direction given in the METAR is the direction the wind is coming from, so it is easy to compare this wind to your given runways. <br/>
-'''Example'''
-{| class="prettytable"
-|-
-|You are the Tower controller at Salzburg Airport. The only runway at Salzburg is runway 16-34 so you have two directions available (roughly 160° and 340°.) The wind is coming from 180° at 5 knots. <br/>
-So the usual Runway in use would be rwy 16 for takeoff and landing.
-|}
-However, at most airports a preferred runway configuration is defined (Find them here: [[Study Guide:Airport Details]]) which should be used if traffic situation and weather permits. Aircraft have certain limitations they can operate in, so normally the tailwind component should not exceed 5-10 knots (again depending on airport). Also the allowed crosswind is limited (This depends very much on the aircraft).<br>
-Be aware that it is the pilots responsibility to accept a certain wind component and that this decision is often based on performance issues, so one pilot might accept the next one refuses to take a certain runway.
-So back to our example above.
-{| class="prettytable"
-|-
-|At Salzburg, due to the terrain in the vicinity and city of Salzburg around the airport, runway 34 is preferred for departures and rwy 16 for landing. So the indicated configuration would be DEP 34, ARR 16.
-|}
-====Transition Altitude/Transition Level====
-Die Transition Altitude (TA) beträgt in Wien immer 5000 ft.
-Der Transition Level (TL) ergibt sich in Abhängigkeit zum aktuellen Luftdruck (QNH):<br>
- QNH      < 0977: TA + 3000 ft.
- QNH 0978 - 1013: TA + 2000 ft.
- QNH 1014 - 1050: TA + 1000 ft.
- QNH 1051 >     : TA = TL
-Zwischen der TA und dem TL befindet sich der Transition Layer, der einen Sicherheitsabstand von mindestens 1000 ft. zwischen dem "unteren Bereich" (Airport Elevation bis A5000 ft.) und dem "oberen Bereich" (Standard Luftdruck 1013 hPa bis Untergrenze TL) gewährleistet. Dadurch werden gefährliche Überschneidungen zwischen dem an- und abfliegenden Verkehr vermieden.<br>
-====Runway Separation====
-====Departing Traffic====
-=====Departure Seperation=====
-Minimum separation between departing / arriving aircraft is 3NM
-=====Use of the word takeoff=====
-The word take-off shall only be used in combination with the take-off clearence (cleared for take-off). For other phrases use the word departure (ready for departure – NOT ready for take-off!).
-====Arriving Traffic====
-====Merging Departing and Arriving Traffic====
-* Wake Turbulence Separation
-* Conditional Clearances
-===VFR Traffic - Differences===
-VFR traffic can enter/leave the control zone (CTR) via sector SIERRA (to the south), sector ECHO (to the east) and along the Danube river on the route Klosterneuburg – Freudenau. Maximum altitude in these sectors is 1500ft or according to the VFR charts published online at vacc-sag.org.<br>
-VFR flights should be guided into downwind, base and final for landing.<br><br>
-Used phrases:
- OE-AGA, enter control zone via VFR route Klosterneuburg – Freudenau, 1500ft or below,
- QNH 1020, Squawk 4604, report XXXX (i.e. Freudenau)
- OE-AGA hold (orbit) overhead XXXX (i.e. Freudenau) in XXXX (i.e. 2500ft)
- OE-AGA, enter downwind for runway 29, report on downwind
- OE-AGA, enter base for runway 29, report on base
-VFR Flights get their Clearence from Delivery as well. After startup, they will contact Tower for taxi. A possible VFR Clearence could be:<br>
- OE-AGA, verlassen Sie die Kontrollzone über Sichtflugstrecke Klosterneuburg, 1500 Fuß oder darunter,
- QNH 1014, Squawk 4607, Rechtskurve nach dem Abheben so bald als möglich.
- OE-AGA, leave controlzone via VFR-route Klosterneuburg, 1500 feet or below, QNH 1014, Squawk 4607,
- right turn after departure as soon as possible.
- OE-AGA, steigen sie auf 3500 Fuß, melden Sie Donauturm.
- OE-AGA, climb 3500 feet, report Donauturm.
-Note that Wien Tower/Turm can also be contacted in German.
-====Information Positions====
-===Special Situations (High Traffic, Slots, ...)===
-==Study Guide: Radar==
-===Responsibilitys===
-===Airspace Structure===
-LOWW is located very close to the Austrian state boundaries with Hungary, Slovakia and the Czech Republik and space within the TMA (Terminal Maneuvering Area) is very limited.<br>
-Arrivals are being transferred to LOWW_APP by '''five independently working ACC sectors''' (LKAA/ACC Praha, LZBB/ACC Bratislava, LHCC/ACC Budapest, ACC Wien South, ACC Wien North). Therefore final decisions on the arrival sequence are normally made at a distance of approximately 40 NM from touchdown.<br>
-<br>
-LOWW_APP itself operates '''up to four different sectors''', depending on the amount of traffic. Two '''Upper Radar''' sectors specify the arrival sequence for the Lower Sectors. Upper Sectors are operated between FL240 and FL110.<br>
-<br>The '''Lower Radar''' (FL100 and below) will then make final decisions on the arrival sequence by transferring arriving aircraft to the '''Director''', who issues vectors onto the final approach track and sets up a safe flow of landing traffic. Unless otherwise instructed, initial contact on Director frequency (normally 119.800) shall be made by stating the callsign only in order to reduce frequency load.<br>
-<br>
-When the appropriate spacing is assured until touchdown, Director will transfer the arriving aircraft to Tower.<br>
-===Radar Princples===
-===Minimum Radar Separation===
-====General====
-====Vertical Separation====
-====Horizontal Separation====
-===MRVA, MSA===
-===Structure of Flightplans and Routings===
-====SIDs====
-====STARs====
-====Types of Instrument Approaches====
-===Basic Vectoring===
-===Seperation and Sequencing Techniques===
-====Planning====
-LOWW_APP is aiming at a maximum of 15 minutes flight extension for sequencing of arrivals to LOWW within the TMA (Terminal Maneuvering Area). Arriving aircraft will normally get radar vectors to '''one common downwind'''.<br>
-====Delay Vectoring====
-====Speed Control====
-For efficient sequencing and spacing of arriving aircraft LOWW_APP will instruct specific indicated airspeeds to be maintained (speed control). Aircrews are expected to maintain instructed speeds as accurately as possible. In case of unability to maintain instructed speed (weather reasons, operating limitations etc.) ATC has to be informed immediately.<br>
-====Holding====
-====Coordination with adjacent Sectors====
-===VFR Traffic===
-====Flight Information Positions====
-===Abnormal Situations - Emergencies, Radio Failures===
-'''All Weather Operations (AWO)'''<br>
-With Low Visibility Procedures in operation, standard approach runway will be runway 16.<br>
-Arrivals will be vectored out of the holdings into the '''left hand circuit''' for runway 16. Approximate track distance from the holdings to touchdown shall be calculated with '''40 to 70 nautical miles'''.<br>
-===Controlling CTR Positions===
-==Study Guide: Airport Details==
-=== LOWW (Wien Schwechat) ===
-==== Pisten ====
-* '''11/29:''' Beton, 3500x45 Meter, ILS
-* '''16/34:''' Beton, 3600x45 Meter, ILS
-==== Visual Approches ====
-Approaches using "Own Separation". Visual Approaches will be issued whenever the traffic situation permits. Due to several noise sensitive areas in the vicinity of Vienna Airport, LOWW_APP has to impose certain restrictions on visual approaches:
-* NO visual or short approaches will be issued in the right-hand circuit for runway 16 and in the left-hand circuit for runway 11 (City of Vienna).
-* Aircraft instructed to "maintain own separation" during final approach are expected to maintain a safe and efficient separation (normally less than 2,5 NM) to the preceding landing aircraft.
-==== Possible Runway Configurations ====
-The runway utilization concept for LOWW is based on the fact that the airport layout with it's crossing runways normally does '''not allow simultaneous approaches''' to both runways. So, whenever possible, runways 11/29 and 16/34 will be used independently to allow departures on one runway (normally 16 or 29) while using the other runway for landing aircraft.<br><br>
-'''Possible runway configurations are:'''<br>
-* ARR RWY 11 / DEP RWY 16 >>> SE winds, if no simultaneous approach possible
-* ARR RWY 34 / DEP RWY 29 >>> calm/NW winds
-* ARR RWY 16 / DEP RWY 29 >>> calm/SW winds
-* ARR RWY 11/16sim. / DEP RWY 16 >>> calm/SE winds, simultaneous approach possible
-Simultaneous approaches to runways 11 and 16 are conducted only at tower's discretion during certain weather conditions (visual reduction of separation). Aircrews are advised to show landing lights as soon as possible.<br>
-In case of technical uncertainties during final approach - that might be possible lead to a missed approach - aircrews are asked to inform ATC immediately.<br>
