We track Runway Visual Range (RVR) and overall visibility at Krakow-Balice to see whether fog in Krakow could limit departures or arrivals.
What Is RVR and Why It Matters
RVR is the distance a pilot can see runway lights from the cockpit and is more decisive than generic horizontal visibility. The lowest of the touchdown, midpoint, and stop-end sensors often sets the operational limit, defining whether an approach can continue.
How to read RVR reports
- 550–750 m: usually sufficient for CAT I approaches.
- 300–550 m: requires Low Visibility Procedures and fully available ILS/lighting.
- Below 300 m: severe restrictions, likely holds or diversions.
Required Minimum Visibility for Landing and Takeoff
Minimums depend on ILS category, aircraft equipment, and crew qualifications. Typical landings at Krakow need at least around 550 m RVR for CAT I, while takeoffs often require about 400 m with centerline and edge lighting operational.
What ops teams check
- RVR values and trend at all three measurement points.
- ILS availability, approach lighting, and centerline markings.
- Airline-specific minima and crew approvals.
How Fog Reduces Visibility and Affects Operations
Fog at Krakow-Balice drops RVR, lowers arrival/departure rates, and can trigger diversions when minima are breached. Knowing is there fog in Krakow helps gauge the risk of delays or reroutes.
Passenger checklist
- Monitor METAR/SPECI for RVR changes and LVP activation.
- Watch airline updates on delays, cancellations, or rerouting.
- Plan alternatives if fog persists through your departure slot.
