AIP LSGS
LOW PERFORMANCE SID RNAV and HIGH PERFORMANCE SID RNAV
HIGH PERFORMANCE SID RNAV only RWY 25:
This departure is only valid for pilots holding a type B qualification or holding an A qualification under certain weather conditions. For pilot holding a type A qualification the HIGH PERFORMANCE can only be used during day time.
LOW PERFORMANCE SID RNAV, Day only :
This departure is made up of a VFR segment whose route is recommended (see chart: LOW PERFORMANCE SID RWY 07/25 – RNAV). It is recommended that you turn off before the village of Vercorin to reach the GS300 waypoint.
When a LOW PERFORMANCE SID RNAV is performed, a pilot may request from ATC an early left turn to the west if he does not intend to fly to the village of Vercorin and GS300. After approval, ATC will inform the pilot that IFR will start at GS301 (1 NM west of LSGS). It is the pilot’s responsibility to comply with the climb gradient and minimum altitude constraints.
Operations at night
For operation at night, the following conditions need to be fulfilled:
IFR Arrival
- RWY 25 must be in use
- DA according to aircraft category
- Visibility 5 Km or more
- The pilot must hold a Qualification type B
- ACFT shall be able to fly the missed approach procedure.
IFR Departure
- RWY 25 must be in use
- Visibility 550 RVR
- HIGH PERFORMANCE SID RNAV only
- The pilot must hold a Qualification type B
Military activity (MIL ON)
Military activity ON (MIL ON) local time :
Military activity generally takes place from Monday to Friday, from 08:30 LT to 12:00 LT and from 13:30 LT to 17:00 LT.
Once the departure clearance has been issued, ATC will inform the pilot whether the altitude restrictions must be applied or whether they can be ignored. During normal military operating hours, this information will normally be passed on during taxiing as this is a “last minute coordination” with military ATC.
Temporary Reserved Areas (TRA):
Extract from a skyguide document
The IFR approach procedures established for Sion airport (LSGS) are crossing military training areas (Temporary Reserved Areas). This is due to terrain and cannot be avoided. As a consequence, restrictions apply to IFR approaches to LSGS. The precise type and level of restrictions depend on the type of activity conducted within the Temporary Reserved Areas. For the purpose of ensuring safe operations, appropriate coordination procedures have been established between civil and military ATC units.
The use of ATC slots for this purpose is considered less appropriate in light of new types of restrictions available at flight planning level, which provide significantly more lead time than ATC slots. This means that any delay for IFR approaches due to military activity is normally known already the day before operations as of 16:00 UTC (15:00 UTC during summer time period), whilst ATC slots are assigned only 2 hours before EOBT (Estimated Off-Block Time).
As of 6th November 2020, a flight planning restriction (“LST900ZR”) will be implemented in Eurocontrol systems whenever relevant TRAs are unavailable for arrivals to LSGS. As a consequence, flight plans will be rejected during those periods when IFR approaches to LSGS
There are 2 ways to avoid this flight planning restriction:
- Re-planning the arrival of the flight concerned before or after the relevant time period
- If meteorological conditions permit, a rejection can also be avoided by cancelling the IFR part of the flight at VADAR / FRI / VALOR / MOLUS. Use this option with special care only, as flights unable to cancel IFR will need to divert or expect excessive holding time.
