3.5.4.  Types of services

3.5.4.1 Personal briefing and consultation for flight crew members is provided. Flight documentation comprises a significant weather chart, an upper wind and upper air temperature chart and the latest available aerodrome forecast for the destination and, if required, for its alternate aerodromes.
3.5.4.2 For the planning of VFR flights, plain - language summary forecast of en - route weather conditions may be requested from Sal.
3.5.4.3 Cloud height is measures by ceilometers. These observations are representative of the landing area.
3.5.4.4 Distant reading thermometers at Sal Island / Amilcar Cabral, Praia / Nelson Mandela and Sao Pedro / Cesaria Evora are used to measure the air temperature in conditions normally representative of the temperature over the runways.

3.5.5.  Notification required from operators

3.5.5.1 Notification from Operators in respect of briefing, consultation, flight information needed by them (ref. ICAO Annex 3, 2.3) is normally for inter - continental flights of more that 3500 KM. Such notification should be received at least 6 hours before the expected time of departure.

3.5.6.  Aircraft reports

Pursuant to ICAO Annex 3, 5.3.1 the making and transmission of aircraft reports (AIREP) are required at the following ATS reporting Points:

EDUMO TENPA IPERA GUNET GAMBA IREDO CVS ORABI KENOX
AMDOL POMAT ONOBI BOTNO TUTLO XIBOT VEPOP ERNEK TEGTO

3.5.8.1  General

For the safety of air traffic, the meteorological authority maintains an area meteorological watch and warning service. This service consists partially of a continuous weather watch within the lower and upper FIR and the issuance of appropriate information (SIGMET) by Meteorological Watch Offices (MWO) and partially of the issuing of warning for the respective aerodrome and, subject to agreement, for other aerodromes by all aeronautical MET offices.

3.5.8.2  Area meteorological watch service

The area meteorological watch service is performed by the following Meteorological Watch Office:

  1. Main Aeronautical Meteorology Centre (Centro de Meteorologia Aeronautica Principal)

The MWOs issue information in the form of SIGMET messages about the occurrence or expected occurrence of one or several of the following significant meteorological phenomena:

  1. thunderstorms

  2. severe turbulence

  3. severe icing

  4. severe mountain waves

  5. heavy sand storm / dust storm

  6. volcanic ash cloud

  7. tropical cyclone

The SIGMETs are issued in abbreviations and plain language using ICAO abbreviations and are numbered consecutively for each day commencing at 0001. Their period of validity is generally limited to less than 4 hours from the time of transmission.

The MWOs transmit SIGMETs issued by themselves, as well as SIGMETs of adjacent MWOs and, upon agreement, also SIGMETs of other MWOs, to the regional control centre competent for the FIR or UIR concerned.

In addition to the issuance of SIGMETs, the MWOs will inform the regional control centre about the occurrence or expected occurrence of thunderstorms, moderate icing, light to moderate hail, or moderate turbulence within the FIRs concerned. The information is intended for the safety of low level flights and is limited to the lower airspace.

3.5.8.3  Warning service

Warnings for the protection of parked and moored aircraft or other equipment at the airport are issued by all aerodrome meteorological offices, if one or several of the following phenomena are expected to occur at the airport:

  1. squall

  2. thunderstorm

  3. hail

  4. frost

  5. heavy rime deposit

  6. heavy snow

  7. freezing precipitation

Differences from these criteria have to be agreed upon locally.

The warnings are generally issued in English and are distributed in accordance with a distribution list which has to be agreed upon locally. In order to guarantee rapid dissemination of the warnings, the distribution list to be used shall, as far as possible, contain only one recipient for an interested group. This recipient will be responsible for the further dissemination of the warning within the group.

SIGMET information is disseminated through directed transmissions to aircraft general calls

  1. by the Area Control Centre (SAL ACC) for SAL OCEANIC FIRSAL OCENIC FIR / UIR

  2. by the ATS unit for their own area of responsibility.
