3 Procedures

3.1 Definitions

A release is an authorization for the accepting ATS unit to climb, descend and/or turn (by no more

than 45°) a specific aircraft before the transfer of control point. The transferring ATS unit remains

responsible for separation within its Area of Responsibility unless otherwise agreed.

Traffic may be cleared direct to its co-ordination point (COP) without prior coordination.

Traffic overflying EDMM and/or LKAA shall be handed off on a valid ATS route at a valid RFL using

the semi-circular cruising level rule (even/odd). Direct routings shall be coordinated.

Traffic shall be handed off at the levels, defined in the regulations below. If a specified level

restriction cannot be met due to a lower RFL, traffic shall be handed of at RFL, if this does not

cause a conflict with any other traffic. Otherwise traffic shall be coordinated.

If a traffic situation is not covered herein, individual coordination between the concerned sectors

shall be made.

After Transfer of communications, traffic is NOT released for climb, descent or turns until Transfer

of control or otherwise specified in this Letter of Agreement.

3.3 VFR flights from München FIR to Praha FIR For controlled VFR flights and VFR night flights coordination, transfer of control and transfer of communication shall take place as for IFR flights. Uncontrolled VFR flights shall be transferred to the appropriate sector if in radio contact. If online, LKAA_I_CTR (Praha Information) 126.100, shall be the primary sector for uncontrolled VFR flights.

3.4 VFR flights from Praha FIR to München FIR For controlled VFR flights and VFR night flights coordination, transfer of control and transfer of communication shall take place as for IFR flights. Uncontrolled VFR flights shall be transferred to the appropriate sector if in radio contact. If online, EDMM_I_CTR Langen Information 120.650), shall be the primary sector for uncontrolled VFR flights.


4 Transfer of Control and Transfer of Communications

4.1 Transfer of Control without systematic use of the bi-directional speech facilities Transfer of Control without systematic use of the bi-directional speech facilities (Silent Transfer of Control) shall take place at the Area of Responsibility (AoR) boundary.

4.2 Transfer of Communications Transfer of Communications shall take place no later than Transfer of Control. Inability to accept hand-off of an aircraft, due to capacity issues, technical problems or because the receiving ATS unit is about to close, must be coordinated with the releasing ATS unit.

4.3 Transfer of Radar Identification (Hand-off) Transfer of Radar Identification may be effected without systematic use of bi-directional speech facilities provided the minimum distance between successive aircraft about to be transferred has one of the following values: a) 10 NM if the succeeding aircraft is not faster b) if the succeeding aircraft is faster: 20 NM and Mach number differing by not more than M 0.05 at FL250 or above, or 20 kts IAS below FL250 are assigned to aircraft concerned; 30 NM and Mach number differing by not more than M 0.1 at FL250 or above, or 40 kts IAS below FL250 are assigned to aircraft concerned 1. Any direct routing which deviates from the flight planned route of the flight to be transferred

is indicated in the Euroscope and has been coordinated between the transferring and accepting ATS stations (either by chat or by COPN/COPX tools)

2. Any assigned heading has been coordinated between the transferring and accepting ATS stations by chat.

Hand-off without prior coordination shall be initiated by the releasing ATS unit no later than 2 minutes before the Area of responsibility boundary. Transfer of Radar Indentification (Hand-off) shall be accepted by receiving unit only after a successful Transfer of Communications. Note: In case the receiving ATS unit has set its state to “break”, transfer of communication shall only take place after prior coordination or after the track has been accepted.

4.4 SSR Code Assignment

Both ATS units shall transfer flights with verified discrete SSR codes. SSR Code 1000 is used for

sufficiently equipped IFR flights within Mode-S zone.
