LoA between vacc Switzerland (LSAS) and VACC Italy Page 3 of 17 GENERAL REGULATIONS Handoffs of communication shall be made latest 10 NM prior to handoff of control. After handoff, traffic is NOT released for climb, descent, turns or changes on speed restrictions unless otherwise specified in the regulations below. Both AoR are using the North/South-rule (North EVEN, South ODD). Therefore traffic which is not handed off at a level mentioned in this LOA shall be on an odd FL when flying southbound and on an even FL when flying northbound. Spacing between two aircraft on same level and same routing crossing BoR shall be at least 10 NM if the speed of the succeeding traffic is equal or less than the speed of the preceding traffic, otherwise at least 15 NM. Spacing deviating from this regulation shall be coordinated. All level restrictions are maximum levels. Lower level can be assigned at discretion of the responsible controller without any coordination Traffic which is not handed off at a level mentioned in this LOA shall be on an odd FL when flying southbound and on an even FL when flying northbound. Maximal FLs higher than FL390 are not explicitly stated. If not otherwise specified, traffic shall be in level flight when crossing BoR. FLxxx / FLxxx means descending / climbing to a specified FL, without any further restriction. In that case, traffic must NOT be in level flight when crossing BoR. For climbing traffic higher level may be assigned regardless the regulations below preconditioned that traffic reaches cleared level before crossing BoR. If a traffic situation is not covered herein, individual coordination between the concerned sectors shall be made. Agreements between controllers always have higher priority than regulations defined in this LoA. A controller from one party shall inform a controller from the other party about the cancellation of an agreement if he plans to go offline and the agreement won t be continued by another controller of his own party. LIMM TMA = LIMC, LIML, LIME and LSZA
LoA between vacc Switzerland (LSAS) and VACC Italy Page 4 of 17 HANDOFF REGULATIONS This section contains regulations for handoff procedures from vacc Switzerland to vacc Italy or vice versa. Both are further referred to as unit. Handoff rate: Requesting-unit: None-requesting-unit: Number handoffs per time (can also be zero) The unit who has requested a certain handoff rate The opposite unit of the requesting-unit An aircraft to be transferred from one unit to the other shall be kept in the airspace of the transferring unit until one of the following conditions applies: The handoff was accepted by the receiving unit At least 10 minutes have passed since the handoff request and none of the regulations below applies. The receiving unit did not accept the previous handoff request and this previous handoff request was made less than 10 minutes ago. A unit can order a maximum handoff rate during a maximum of 30 minutes. It remains effective until either the time has expired or it was cancelled by the requesting-unit. The none-requesting-unit shall strictly stick to such an order as long as it is effective. In all case, a unit shall monitor the traffic situation in the other unit. If necessary, a unit shall on own discretion establish suitable measures to relieve the other unit. This can be for example a certain handoff rate or an alternative routing for some flights.
