A bright sunny day, but a persistent stratiform cloud blocks the view of the runway when approaching the minimums. Or even worse, more than sufficient visibility, but a thick cloud layer extends below CAT 1 minimums and Low Visibility Operations (LVO) are not (yet) activated… A go-around seems imminent while the weather forecast and ATIS information may not have caused you to expect this course of action.
This is why we put together brief guidance with mitigating measures that could help crews operating into any airport, where a ceiling/vertical visibility is not considered when deciding on the type of operations.
An approach in instrument meteorological conditions (IMC) may only be continued below the appropriate minimum if the required features of the landing runway, the runway or the approach lights are in sight at these minimums. The required visibility assures that the lights are within a distance from the pilots’ eyes that it is physically possible to see them.
