This section is intended to establish the procedures and criteria official standard for the operation of aircraft and air traffic control within the FIR Montevideo, reading is recommended for all pilots operating in the same and mandatory for drivers.
The same shall apply within the framework of the IVAO network simulation, its purpose being to get the virtual airspace Uruguayan as possible resemble the real.
For this purpose the definitions, characteristics and procedures thereof are delineated, this information being obtained from actual official documentation such as AIP, LAR, ICAO Documents attached by Uruguay and other documentation actual AIS department.
It will serve as a reference guide for training and assessments in Uruguay within the IVAO network and regional divisions updated copies thereof for application in the framework of multi-divisional operations surrender.

The operation of aircraft both in flight and on the movement area of an aerodrome, shall comply with the general rules and also during the flight:
Visual Flight Rules (VFR)
Instrument Flight Rules (IFR)
Minimum VMC visibility and distance from clouds

The helicopters will be allowed to conduct flights with horizontal visibility less than 800 M and cloud base equal to or greater than 800 FT, provided the operation is conducted without hazard to persons and property on the surface, maneuvering at a speed that gives adequate opportunity to observe other traffic or any obstacles in sufficient time to avoid a collision

Note: All aircraft below flight level 100, maintain a specified speed less than 250 KT

Special VFR flights
When traffic conditions permit, may be authorized special VFR flights subject to the approval of the unit providing approach control service.
When the ground visibility is not less than 1 500 m may be authorized to Special VFR flights to:
- Enter into a control zone for landing, take off.
- Cross the control zone.
- Operating locally within a control zone.

Altimeter settings
For flights in the vicinity of an airport and within terminal control areas (TMA), the position of the aircraft in the vertical plane must be expressed in:
- Altitudes, when they are at the transition altitude or below it, and
- Flight levels, when in the transition level or above it.
Passing through the transition layer the position of the aircraft in the vertical plane must be expressed in flight levels during ascent and at altitudes during descent.

Transition Level

The transition level will be established by the air traffic services
according to the following criteria for the whole national territory according to the value of QNH in the Aerodrome

Cruising levels

Cruising levels to be carried out a flight or part thereof be referred to as

- Flight levels, for flights that are made at a level equal to or above the level of lowest usable flight or, where appropriate, for flights that are made above the transition altitude

- Altitudes, for flights that are made below the lowest usable flight or, where appropriate, for flights that are made to the transition altitude or below it

Cruising Level tables

Table of cruising levels applicable in Uruguay

ATS airspace are classified and designated in accordance with indicated below:

- Class A. IFR flights only are permitted, is provided to all service flights air traffic control and are separated from each othe

- Class C. IFR and VFR flights are permitted, all flights service air traffic control and IFR flights are separated from other IFR flights and VFR flights is provided. VFR flights are separated from IFR flights and receive traffic information in respect of other VFR flights

- Class E. IFR and VFR flights are permitted, all flights are provided service IFR air traffic control and are separated from other flights IFR.- All flights receive traffic information as far as Class E factible.- It will not be used for control zones

- Class F. IFR and VFR flights are permitted, all participating IFR flights receive service air traffic advisory and all flights receive flight information service if requested. When service air traffic advisory is provided, it must be considered normally as a temporary measure until the time service can be replaced by air traffic control

- Class G. IFR and VFR flights are permitted and receive flight information service if requesteed

Air traffic services constitute one of the essential services for the management, safety and flight efficiency, must meet the following objectives:

- To prevent collisions between aircraft;
- To prevent collisions between aircraft on the maneuvering area and between these and the obstacles on that area;
- Speed up and maintain an orderly flow of air traffic;
- Advise and provide useful information for the safe and efficient conduct of flights

Air Traffic Services

Air traffic services comprise three services the following denominations:

- Service Area Control (ACC): The provision of services air traffic control for controlled flights usually within an FIR.
Example: SUEO_CTR
- Approach Control Service (APP): The provision of services air traffic control for those parts of controlled flights associated with arrival or departure usually within a TMA or CTR.

Example: SUDU_APP
- Aerodrome Control Service (TWR): The provision of services for air traffic control aerodrome traffic usually within an ATZ.

Example: SUCA_TWR
Designation of parts of airspace and controlled aerodromes
- Flight Information Regions (FIR). They are designated as flight information regions those parts of airspace in which it is decided to provide flight information service and alerting service with vertical and horizontal limits.

Example: FIR Montevideo.
- Control Areas (TMA) and control zones (CTR). They are designated as control areas or control zones those parts of airspace in which it is decided to provide service air traffic control to all IFR and VFR with vertical and horizontal limits.

Example: Montevideo TMA or CTR Cologne.
- Controlled Airfields (ATZ). They are designated as controlled aerodromes those aerodromes where it is determined to be provided traffic control service with vertical and horizontal limits.
Example: ATZ Adami.

6 - DANGER ZONES, prohibited and restricted
All airspace in which there could be a potential hazard to aircraft operations and / or temporarily or permanently restrict the operation of civil aircraft is classified as:

- DANGER ZONE (D) An airspace of defined dimensions which can be deployed at certain times activities dangerous to the flight of aircraft.

- BOUNDS (P) airspace of defined dimensions on the territory or territorial waters of Chile, within which is prohibited from flying aircraft. It can only decreeing the aviation authority for reasons of national security or military nature.

- RESTRICTED (R) airspace of defined dimensions on the territory or territorial waters of Chile, within which is restricted aircraft flight under certain specified conditions. It can only decreeing the aviation authority for reasons of national security or military nature.

The call letters are: "D" for Dangerous, "P" for prohibited and "R" for Pay preceded by the indicator of nationality: SU and a serial number.
Examples: SU P32, SU R5.
* A description of each area are the ENR and TMA letters of each sector in which its lateral and vertical limits, restrictions or danger, schedule and any other information required are indicated.

Responsibility for control of an aircraft is transferred from one control unit to another air traffic, as follows:
Between two units providing area control service or approach.

- Responsibility for control of an aircraft shall be transferred from the unit providing control service area, which provide such a service in an area adjacent control at the time the control center air or approximation exercises control of the aircraft calculated that the aircraft will cross the common boundary of both areas of control.
Among the unit providing air control service or approach and aerodrome control tower.
- With traffics arrival, you are in the vicinity of the airfield, and considers that it can perform the approach and landing by visual reference to the ground or has reached a point or agreed level.
- With traffics out: Prior to the time the aircraft leaves the vicinity of the aerodrome VMC; or before the aircraft passes operating in IMC. When conditions prevail at the aerodrome IMC will be transferred immediately after the aircraft is in flight.

Coordination of the transfer

Responsibility for control of an aircraft shall not be transferred from a dependence on air traffic control to another, without the consent of the accepting control

- The transferring control unit shall communicate to the accepting control unit with adequate advance according to the influx of aircraft

- Identification and type of aircraft

- SSR Code
- Origin / Destination
- Flight level required
- Point and estimated time of transfer
- Any other relevant information

- The accepting control unit shall: indicate its ability to accept control of the aircraft

GENERAL points Transfers between ATS units

Letters International Agreement

In the letters published in the corresponding channels Agreement points transfers and other procedures relating to transfers ATS units from neighboring countries will be established

Permissions air traffic control will have the sole purpose of meeting the requirements of providing service air traffic control and verify the correct filling of the flight plan form (FL, route, flight rules, equipment, etc.)
Content of authorization

The authorization of air traffic control contain:
- Aircraft Identification contained in the flight plan;
- Limit the authorization;
- Route of flight;
- The level or levels of flight for the entire route
- Active Track
- SID or output instructions
- Altimeter
- Other restrictions

The controller hear the collation to ensure that the flight crew has correctly acknowledged the clearance or instruction and take immediate action to correct any discrepancies revealed by the read.


All aircraft that are within controlled airspace in Montevideo CTA labeled themselves, the same will be held in the two spaces available, and

Waypoint level with the following criteria:

- In the space FL flight level or altitude at which it was entered you are authorized, if the aircraft already has authorized a method of approximations APP was selected in this box.
- In the WP space limit abbreviated authorization, SID / STAR assigned or approved approach procedure was entered.
- In low-flying aircraft he VFR flight rules FL box was entered as described above but the WP box can be left free or fill it with the acronym: VFR.

all VFR-IFR aircraft transponder codes are assigned within the CTA Montevideo.
Where acceptance of aircraft from other FIR is made must recycle the transponder of the same for the purpose of recording its acceptance in the CTA.
Criteria for allocation of SSR codes
SSR codes - A / 3 mode - awarded by ICAO for identifying flights on the Montevideo FIR correspond to the following series

a) domestic flights, series 11 and 12
b) international flights, series 60,61 and 73

11 - RADAR
The Radar service is provided from PSR and MSSR information.
A radar unit generally works as an integral part of the ATS system and provides radar service to aircraft the maximum extent possible to meet the operational requirement. Many factors such as radar coverage, experience and workload of controllers, equipment capacity and congestion of communications may affect these services, the controller can determine whether it can provide or continue to provide radar service in each specific case.

The pilot will know when radar services are provided because the radar controller will use the following call sign:

- Within the Control Area Montevideo "Montevideo Radar"
- Carrasco inside the area Terminal: "Carrasco Radar"

Radar coverage

Control Center and Approach Montevideo Carrasco operate:

a) Primary Radar PSR 60 NM located in the coordinates Carrasco Intl Airport
34 ° 49'54.9 "S 056 ° 00'42.8" W
b) Secondary Radar MSSR 220 NM located in the Carrasco Intl Airport 34 ° 49'54.9 coordinates "S 056 ° 00'42.8" W and secondary radar MSSR 220 NM located in Durazno / Santa Bernardina Alternative Intl coordinates 33 ° 21 '04 .7 "S 056 ° 30'09.9" W
Note: Information radar data Integrates Ezeiza

Application of radar control service

Radar identification is obtained in accordance with the provisions specified by the ICAO.
The radar control service is provided within the airspace controlled by Montevideo and Carrasco Radar under radar coverage. This service may include:
- Radar traffic separation arriving, departing and found en route;
- Radar surveillance traffic that comes, goes and it is en route to provide information regarding any significant deviation from normal flight path;
- Vectoring when required;
- Assistance to aircraft in emergency;
- Assistance to aircraft flying VFR;
- Warning information on the position of other aircraft considered constitute danger;
- Information to assist the aircraft navigation.

The minimum horizontal radar separations are as follows:
- Primary Radar, 5 NM
- Secondary Radar 10 NM
Note: The minimum horizontal separation will increase when circumstances such as bearings or relative speeds of the aircraft, the workload of controllers and difficulties caused by congestion of communications, so require.
Levels and / or altitudes assigned by the radar controller to pilots will provide a minimum terrain clearance according to the phase of flight.
