LOA Langen FIR

General

Purpose

The purpose of this Letter of Agreement is to define the coordination procedures to be applied within Langen FIR when providing ATS to air traffic (IFR/VFR) on the VATSIM network. All information and procedures described in this Letter of Agreement shall not be used for real world purposes.

Operational Status

All operational significant information and procedures contained in this Letter of Agreement shall be distributed to all concerned controllers by appropriate means. This Letter of Agreement itself constitutes public information.

Validity

This Letter of Agreement becomes effective on March 25 2021. Updates may be applied continuously by agreement of the NAV Departments and will be published in the respective forums.

Areas of Responsibility & Sectorization

Areas of Responsibility

The lateral and vertical limits of the respective areas of responsibility are as follows:

Langen FIR

Lateral limits: Langen FIR as described in AIP Germany
Vertical limits: GND – FL660

Procedures for Coordination

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. Wherever VATSIM callsigns are used to describe the terms of a certain procedure, this procedure is also applicable for all higher stations that take over the responsibilities of said station. E.g., procedures for an APP-station are also applicable for the respective CTR station fulfilling the duties of said APP station. The use of VATSIM callsigns in this document includes any variation of said callsigns. E.g. any procedure applicable for EDGG_CTR may also be used by EDGG_X_CTR, EDUU_X_CTR or EDYY_X_CTR.

General Conditions

Coordination of flights shall take place via the agreed coordination points (COP). Coordinated flights shall be handed off via a valid COP. Any deviation shall be coordinated verbally, by text or by EuroScope inter-sector coordination. 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 off 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.

VFR flights within Langen FIR

For controlled VFR flights and VFR at night flights above 2500 feet GND 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, EDGG_W_CTR (Langen Information (North)), EDGG_V_CTR (Langen Information (East)), EDGG_F_CTR (Langen Information (South)), EDGG_U_CTR (Langen Information (West)) shall be the primary sectors for uncontrolled VFR flights.

Special Procedures

No special procedures in use.

Transfer of Control and Transfer of Communications

Transfer of Control

Transfer of Control shall take place at the boundary of AoR.

1. If the downstream sector in EuroScope is set to .break, Silent Handoff is suspended and transfer of communication can only take place after the downstream sector has assumed the flight via the appropriate function of the radar client.
2. If it becomes necessary to reduce or suspend transfers, a 5 minute prior notification is required.
3. When transfers are suspended, Silent Handoff is suspended as well.

Silent transfer of control

The following values for silent transfer of control strictly apply for aircraft on same flight level. If possible, they should also be met between aircraft on different flight levels, but with same destination:

1. If preceding aircraft is on same speed or faster: 10nm
2. If succeeding aircraft is faster by 20kts/M0.05 or less: 20nm
3. If succeeding aircraft is faster by 40kts/M0.10 or less: 30nm

Transfer of Communications

Transfer of Communications shall take place no later than Transfer of Control.

Hand-Off procedure

Unless otherwise agreed between stations online, the following hand-off procedure, called Silent transfer of control, shall apply:

1. The upstream sector initiates a transfer via the appropriate function of the radar client.
2. The upstream sector sends the aircraft to the frequency of the downstream sector by voice or text.
3. Upon initial call, the downstream sector assumes the flight via the appropriate function of the radar client.
4. The transfer of communications shall be initiated early enough so that the pilot will call the downstream controller before or shortly after reaching his sector.

SSR Code Assignment

Both ATS units shall transfer flights on verified discrete SSR codes or for Aircraft with Mode S capabilities and suitable destinations code 1000. Any change of SSR code by the accepting ATS unit may only take place after the transfer of control point.
