1. Purpose

The purpose of this Letter of Agreement is to define the coordination procedures to be applied between

Padova ACC and Zagreb ACC when providing ATS to General Air Traffic (IFR/VFR) and Operational Air

Traffic on the IVAO Network. These procedures are supplementary to those specified in ICAO,

EUROCONTROL and national documents.

2. Areas of Responsibility

Vertical limits of Padova ACC are:

Padova Radar NE2 SFC – FL 285

Padova Radar NE4 FL 285 - UNL

Padova Radar SD2 SFC – FL 285

Padova Radar SD4 FL 285 - UNL

Lateral limits of Padova ACC are shown on the diagram below:

Aircraft shall be transferred to the respective ATS ACC unit.

Vertical limits of Zagreb ACC are:

Above TMA Pula FL 135 – FL 660

Above TMA Zadar FL 155 – FL 660

Above TMA Split FL 205 – FL 660

Below above-mentioned lower limit FLs (and if above 1000 ft AGL) aircraft shall be transferred to the

respective ATS approach unit – Pula Radar (LDPL APP), Zadar Radar (LDZD APP), Split Radar (LDSP APP).

Lateral limits of Zagreb ACC along with lateral limits of TMA Pula, TMA Zadar and TMA Split are shown on

the diagram below:

Red line depicts AOR between Zagreb ACC and respective TMAs and Milano FIR. Airspace northwest of

green line depicts Pula TMA. Airspace between yellow and green lines is shared between Pula and Zadar

TMA. Airspace between yellow lines depicts Zadar TMA. Airspace between magenta and yellow lines is

shared between Zadar and Split TMA. Airspace south of the southernmost yellow line is Split TMA.

1000 ft AGL – FL 205 „D“< 7500 ft „C“ > 7500 ft – FL205

5. Transfer of Control

Transfer of communication shall normally occur 2 (two) minutes before the aircraft reaches respective

Transfer of Control point (FIR boundary), and not later than reaching the TOC point.

Transfer of control occurs when the aircraft passes TOC point (FIR boundary). Transferring ATC unit is

responsible for the aircraft's vertical and horizontal separation until it passes the TOC point.

Traffic shall be handed over with a minimum horizontal separation of 10 nm between aircraft,

maintaining this distance or increasing (if necessary on parallel headings or by using speed control) or

1000 feet vertical separation (between RVSM approved aircraft, and aircraft below FL 290) and 2000 feet

in other cases. Unless coordinated via IvAc Chat or IVAO Intercom or released as specified in this LoA, the

receiving ATC unit shall not give aircraft a clearance or instruction to climb or descend until it has passed

the TOC point.

Transferred aircraft are released for turns not greater than 45°.

6. ATS Routes, Coordination Points and Flight Level Allocation

6.1. Free Route Airspace

FRAIT (Free Route Airspace Italy) is available H24 from FL 335. If there is an airway after the Transfer

Point (this means that aircraft won’t enter in FRAIT airspace) traffic must be cleared at maximum FL 320

or FL 330.

Cross-border FRA procedures (SEAFRA – South East Axis Free Route Airspace) are available H24 from FL

325 up to FL 660 in the airspace formed from airspaces of Zagreb FIR/UIR, Sarajevo FIR and Beograd

FIR/UIR excluding areas where responsibility for the provision of ATS is delegated to ATS units other than

Zagreb ACC or Beograd ATCC and including area where responsibility for the provision of ATS is delegated

to Zagreb ACC.

7. VFR Flights

7.1. Milano FIR

All VFR flights entering Italian airspace shall be coordinated with Padova FSS (if available).

VFR traffic from Zagreb AoR requesting to enter CTA VENETO, CTA COMACCHIO and/or ADRIATICO Nord

shall be coordinated with Padova ACC.

7.2. Zagreb FIR

Unless specially authorized by Zagreb ACC, VFR flights within FIR Zagreb shall not be operated above FL

195. Such special approval shall not be granted for enroute VFR flights.

For departure and arrival from/to controlled and uncontrolled airports in Croatia VFR traffic shall use

VFR reporting points prescribed on the charts or in the VFR Manual Croatia.

8. Validity

This Letter of Agreement becomes effective 01/05/2017, and supersedes the Letter of Agreement

between Padova ACC and Zagreb ACC dated 01/09/2009.

A.1 Definitions

ATS Area of Responsibility

An airspace of defined dimensions where a sole ATS unit has responsibility for providing air traffic

services.

General Air Traffic (GAT)

All flights which are conducted in accordance with the rules and procedures of ICAO and/or the

national civil aviation regulations and legislation.

Operational Air Traffic (OAT)

All flights which do not comply with the provisions stated for GAT and for which rules and

procedures have been specified by appropriate national authorities.

Reduced Vertical Separation Minimum (RVSM)

A vertical separation minimum of 300 m (1 000 ft) which is applied between FL 290 and FL 410

inclusive, on the basis of regional air navigation agreements and in accordance with conditions

specified therein.

Release for Climb

An authorization for the accepting unit to climb (a) specific aircraft before the transfer of control. Note: The transferring unit/sector remains responsible within its Area of Responsibility for separation between the

transferred aircraft and other aircraft unknown to the accepting unit/sector, unless otherwise agreed.

Release for Descent

An authorization for the accepting unit to descend (a) specific aircraft before the transfer of

control. Note: The transferring unit/sector remains responsible within its Area of Responsibility for separation between the

transferred aircraft and other aircraft unknown to the accepting unit/sector, unless otherwise agreed.

Release for Turn

An authorization for the accepting unit to turn (a) specific aircraft away from the current flight

path by not more than 45° before the transfer of control. Note: The transferring unit/sector remains responsible within its Area of Responsibility for separation between the

transferred aircraft and other aircraft unknown to the accepting unit/sector, unless otherwise agreed.
