List of flight level allocations within FIR LOVV

Introduction

These lists provide a complete overview of all intersector handover levels within LOVV FIR.

from unit: the upstream unit that is delivering the flight.
ADES: aerodrome of departure.
ADEP: aerodrome of destination.
via: The route, line or sector the flight passes through. If none are applicable for a certain flight, individual coordination is necessary.
cleared level: The exit level the fight shall be delivered by the upstream unit. This is considered to by "climbing" or "descending" as applicable except if stated otherwise in conditions.
conditions: conditions that have to be met by the upstream unit or that are applied during the handoff procedure.
HUFL: Highest usable flight level (sector's top vertical limit).
LUFL: Lowest usable flight level (sector's bottom vertical limit).

AoR: area of responsibility (sector).
MELK line: the western sector border of LOWW_APP connecting the points MASUR and BARUG.
PINKA line: the southern sector border of LOWW_APP connecting the points RUPET and NIGSI.

Transfer of control: Takes place when an aircraft has left the upstream sector and entered the downstream sector. Transfer of control can take place earlier if a release has been given by the upstream sector.
Transfer of communication: Takes place whenever initiated by the upstream sector. Transfer of communication does not imply transfer of control.

General: Aircraft shall be handed over in a way that assures that transfer of communications is completed before the aircraft enters the downstream sector. The upstream sector has to assure, that the aircraft handed over is either clear of conflicts or that the downstream sector is assuming responsibility for maintaining proper separation between the aircraft handed over and other traffic that may create a conflict.
Lateral handoff: Flights shall be handed off in a timely manner by the upstream unit while assuring the conditions will be met. Any deviations from the cleared levels and conditions below are subject to individual coordination. Flights are not considered released for climb or turn unless stated otherwise in conditions.
Vertical handoff: Also called "bottom/ceiling" procedure. When a flight from an upstream unit will be entering the downstream unit's sector through a vertical boundary, the so called bottom/ceiling procedure is in effect. In this procedure, the upstream sector climbs or descends the aircraft to the HUFL or the LUFL as applicable. Once handoff has been initiated and two-way communication with the downstream sector has been established, the downstream sector shall climb or descend the aircraft out of the upstream sector in a timely manner. Flights are considered released for climbs if the upstream sector is below and for descend if the upstream sector is above.
