Sevilla ACC (GCCC) and Casablanca ACC (GMMM)

1. Purpose

The purpose of this Letter of Agreement (LoA) is to define the coordination procedures to be applied between Casablanca ACC and Seville ACC when providing Air Traffic Services (ATS) under IFR or VFR flight rules.

The content of the agreement is approved by the concerned ATC Operations Department and FIR Chiefs and its application is mandatory for all IVAO members providing ATS within an active 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.

Regarding flight levels for transfers between ATC positions:

From	To	Flight Level (1)
Sevilla	Casablanca	ODD
Casablanca	Sevilla	EVEN

(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 Seville airspaces under the responsibility of Seville ACC is Seville Control and consists in one main sector (LECS_CTR) and three secondary sectors (LECS_CEN_CTR, LECS_MAR_CTR, LECS_SEL_CTR). The lateral and vertical boundaries of the airspace under the responsibility of the ACC are indicated in the table below.

LECS_CTR, LECS_CEN_CTR, LECS_MAR_CTR y LECS_SEL_CTR can be consolidated on one main sector (LECS_CTR).

The ATC unit in charge of Casablanca airspaces under the responsibility of Casablanca ACC is Casablanca Control and consists in one main sector (GMMM_CTR) and three secondary sectors (GMMM_OS_CTR, GMMM_OSW_CTR, GMMM_S_CTR).

The lateral and vertical boundaries of the airspace under the responsibility of the ACC are indicated in the images and tables below.

Casablanca Control (South Sector)	GMMM_S_CTR	126.700	SFC-FL660

4. Coordination Procedures

Coordination procedures between the ATC under the responsibility of the Sevilla ACC and those under the responsibility of the Casablanca 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.

Both units shall keep each other advised about relevant VFR flights.

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 Spanish FRA Cell (LECS ACC).
