Barcelona ACC (LECB), Sevilla ACC (LECS) and Alger ACC (DAAA)
1. Purpose
The purpose of this Letter of Agreement is to define coordination procedures to be applied between Alger ACC (DAAA) Sevilla (LECS) and Barcelona ACC (LECB) when providing Air Traffic Services (ATS) to traffic operating under IFR or VFR.
The content of the agreement is approved by the concerned ATC Operation Department and FIR Chiefs and its application is mandatory for all IVAO members providing ATS within and active ATC position concerned by this LoA.
2. General Procedures
Traffic in sequence at the same flight level shall be handed over with minimum spacing of 10 NM.
This separation must be constant (aircrafts restrained to the same speed) or increasing (succeeding aircraft is not faster).
Coordination of speed control should be granted via entries in radar labels and does not need neither approval nor acknowledgement by receiving sector.
Traffic shall be handed over as soon as practical and, whenever possible, at latest 3000 ft before reaching the cleared flight level and in case the transfer point is not defined within this LoA, at latest ten (10) miles before the airspace limits.
Traffic in sequence shall be handed over properly separated and clear of any conflict. The receiving ATC unit cannot issue a clearance modifying the traffic’s route, altitude, or speed (unless by direct coordination between ATC units) until it enters his sector and therefore leaves the area of responsibility from the transferring ATC unit, which remains responsible for separation.

(1) Exceptions listed in section 4
Free Route Airspace Operations within Spanish airspace (HISPAFRA) is defined in Spain (FRA CELL 1) from FL245 to FL660. However, the use of the traditional ATS route network is compatible with HISPAFRA.
Free Route Airspace (FRA) is a specified airspace within which users may freely plan a route between a defined entry point and a defined exit point, with the possibility of routing via published intermediate significant points, without reference to the ATS route network.
3. ATS Unit Description
The ATC unit in charge of FIR and UIR airspaces under the responsibility of Barcelona ACC is Barcelona Control and includes two independent primary sectors (LECB_W_CTR and LECB_E_CTR) and three secondary sectors not adjacent to Alger FIR and irrelevant to this LoA.
The ATC unit in charge of FIR and UIR airspaces under the responsibility of Sevilla ACC is Sevilla Control and consists in only one primary sector (LECS_CTR) and three secondary sectors not adjacent to Alger FIR and irrelevant to this LoA.
The ATC unit in charge of FIR and UIR airspaces under the responsibility of Alger ACC is Maghreb Control and consists in two primary sector (DAAA_CTR and DAAA_N_CTR) which may be split into seven different sectors. Two of those secondary sectors are adjacent to Barcelona FIR (DAAA_NW_CTR, DAAA_C_CTR).
DAAA_NW_CTR, DAAA_C_CTR can be consolidated into a single sector (DAAA_N_CTR) and DAAA_NW_CTR, DAAA_C_CTR and DAAA_N_CTR can be consolidated into a single sector (DAAA_CTR).
The lateral and vertical boundaries of the airspace under the responsibility of the ACC are indicated in the images and tables below.

4. Coordination Procedures
Coordination procedures between the ATC of Barcelona ACC, Sevilla ACC and Alger ACC are defined as follows. They represent a general framework that does not replace the coordination between ATC. Any coordination procedure not mentioned in this LoA must be established on a case-by-case basis.
DAAA, LECB and LECS controllers should know that a traffic will enter its airspace at least 5 NM before, by radar contact and/or coordination with the counterpart.
FRA Horizontal Entry Point (E) is a published Significant Point on the horizontal boundary of the Free Route Airspace from which FRA operations are permitted while an Exit Point (X) is a Point to which FRA operations are permitted.
Entry and Exit points are shown here from the perspective of the Spanish FRA Cell.
