active 2024-12-26 - [Enroute] Changes to Amsterdam controller positions

[VATSIM UK Operations]

Effective 26 December 2024

Summary

A new Letter of Agreement between VATSIM UK and the Dutch vACC will take effect on the above date to reflect amended Amsterdam controller positions:

• EHAA_W_CTR frequency changed to 123.705 - remains highest priority position below FL245 at the UK-EHAA interface
• EHAA_LOW_CTR (125.750) created - covers EHAA airspace below FL245 (i.e. excluding MUAC Delta airspace)
• EHAA_ALL_CTR (134.375) created - covers EHAA airspace below FL245 and MUAC Delta.

The MUAC Delta ownership is also affected by the removal of EUC-MW_CTR - see this post.

vMATS Procedure (EGPX / EGTT)

Deleted text – red and strikethrough. New text in blue.

ScAC 3.4 / LAC 5.4 / LAC 7.4   -   ScAC South / AC Clacton / AC North Sea
ScAC 3.4.5 / LAC 5.4.2 / LAC 7.4.3   -   Amsterdam ACC

Amsterdam ACC is responsible for the whole of the Amsterdam FIR FL245 and below. 

As in real world, the Maastricht Delta (EDYY_D_CTR) and Jever (EDYY_J_CTR) sectors have responsibility for portions of the Amsterdam FIR adjacent to [London/Scottish] above FL245. On VATSIM, in the absence of EDYY positions, Amsterdam ACC and RG Bremen take responsibility of the Delta and Jever sector airspace, respectively.

Note: Amsterdam Radar always has a higher priority over the upper airspace than the Maastricht Eurocontrol position (EUC-MW_CTR).

FL250 is not available as a cruising level in the Amsterdam FIR/UIR.

ScAC 3.4.5.1 / LAC 5.4.2.1 / LAC 7.4.3.1   -   Sectorisation

The coverage priority (left to right) for Amsterdam (SFC-FL245) at the interface with [London/Scottish ACC] is as follows:

EHAA_W_CTR 125.750 123.705 MHz

EHAA_LOW_CTR 125.750 MHz

EHAA_ALL_CTR 134.375 MHz

EHAA_S_CTR 123.850 MHz

EHAA_E_CTR 124.880 MHz (See Note)

Note: The primary callsign for Amsterdam ACC is EHAA_W_CTR, but in cases where they may have logged off leaving EHAA_E_CTR online, EHAA_E shall then be responsible for the whole FIR.

ScAC 3.4.7 / LAC 5.4.4 / LAC 7.4.4   -   Maastricht UAC
[...]
Note: Amsterdam/Bremen Radar always has a higher priority over the upper airspace than the Maastricht Eurocontrol position (EUC-MW_CTR).
[...]

ScAC 3.4.7.1 / LAC 5.4.4.1 / LAC 7.4.4.1   -   Sectorisation

The coverage priority (left to right) for Maastricht UAC (FL245+) at the interface with [London/Scottish ACC] is as follows:

Delta Sector (FL245+)

EDYY_D_CTR 135.960 MHz

EHAA_ALL_CTR 134.375 MHz

EHAA_W_CTR 125.750 MHz

Note: The primary callsign for Amsterdam ACC is EHAA_W_CTR, but in cases where they may have logged off leaving EHAA_E_CTR online, EHAA_E shall then be responsible for the whole FIR.
