Revision as of 14:38, 14 December 2018
For better using follow the steps below to prevend the dynamic update Cycle each month:
1. go to eAIP Austro Control:[1]
2. clck on "current version"
3. click on PART III AD
4. click on AD 2 and then on your prefered airport for example Vienna: LOWW
Bedeutung
LVP sind Verfahren, welche bei schlechter Sicht das Handling auf ATC-Seite eingrenzen. Der Wirkungsbereich dieser Verfahren erstreckt sich auf An- und Abflüge. Damit diese Verfahren aktiv werden können, müssen Flughafen und Flugzeug für die jeweilige CAT-Betriebsstufe freigegeben sein. Dabei ist der jeweilige tiefste Wert derjenige, welcher verwendet werden darf.
BEGRIFFE: RVR/CAT
RVR = Runway Visual Range (Landebahnsicht)
Die RVR wird pro Runway in den Abschnitten "Touchdown Zone", "Mid Point" und "Stop End" gemessen
| ILS-Typ | Minimale RVR | minimale Hauptwolkenuntergrenze |
| Kategorie 1 / Cat I | 550 Meter oder Visibility 800 Meter | 200ft |
| Kategorie 2 / Cat II | 300 Meter | 100ft |
| Kategorie 3a / Cat IIIa | 200 Meter | 50ft |
| Kategorie 3b / Cat IIIb | 50 Meter | 50ft |
| Kategorie 3c / Cat IIIc | keine RVR Begrenzung | keine Höhe |
Verfahren
LVP in der ATIS bekanntmachen (Uniatis-String „&lvp“)
LOW VISIBILITY PROCEDURES IN FORCE
Conditional clearances mit Rücksicht auf die Verhältnisse hinterfragen („do you have approaching traffic in sight?“ bei 2nm Entfernung wäre sinnlos, Taxianweisungen „follow behind … „ machen weiterhin Sinn)
Landefreigabe: mind. 2,5 NM normal 3 NM in Ausnahmefällen (erfordert Info an Piloten) 1nm vor der Pistenschwelle, spätestens Intercept auf das ILS bei 8nm bis 18 NM
Mindestabstand für APP: statt 3 NM entsprechend höher wählen (Bedenke längere Zeiten für RWY cleared etc.) Piloten sind verpflichtet, „runway vacated“ zu reporten
Im Allgemeinen wird bei solchen Sichtverhältnissen die Anflugrate drastisch reduziert.
Phraseologie
Anflugfreigabe durch „normale“ ILS-Freigabe aber mit Übergabe der RVR Werte:
Beispiel: AUA 105, turn right reading 260, cleared ILS 29, RVR 500 metres
Analog bei der Freigabe zur Landung.
Beispiel: AUA 105, RVR 500 metres, wind 310 degrees, 9 knots, RWY 29, cleared to land' bei initial contact Hinweis auf „LVP in operation“
Dem abfliegenden Luftfahrzeug muss mit der Meldung "Hold at CAT II holding point" in einem größeren Abstand von der RWY angewiesen werden.
Auch bei LOW VIS heißt es ganz normal ILS 29 und nicht cleared CAT II ILS 29

LOWK
Verfügbare CAT-2 Runway 28R CAT-3 requires ATC-authorization (MA-climb 4,7%)
LVP WILL BECOME EFFECTIVE WHEN: RVR FOR TOCHDOWNZONE (TDZ) LESS THAN 800 M AND/OR CEILING/VERTICAL VISIBILITY LESS THAN 300FT WILL BE ACTIVATED BY RTF OR ATIS ,,LOW VISIBILITY PROCEDURES IN OPERATION”
for more information refer to point 6: [4]
LOWI Verfügbare CAT-2 oder CAT-3 Runway: keine.
Es gibt auch keine definierten LVP, aber folgende Minima:
- VFR minima: dem Luftraum (Cat. B) entsprechend
- IFR arrival minima: 3km (aircraft cat. A-B) bzw. 5km (Aircraft cat. C-D) flight visibility
- IFR departure minima: 1.500m,
- - except RNAV 0.3 RNP departure: RVR 300m.
- - except low fog or mist: RVR 600m AND visibility >5km above this layer AND no further clouds 3.100ft AGL
for more information refer to point 4: [5]
also check further information in the LOWI_Primer.
