Question

If the instrument approach procedure for the airport of intended landing prescribes an RVR of 2,400, but RVR is not reported on the runway of intended operation, this RVR minimum would be converted to a ground visibility of:

Answer 1

When an RVR of 2,400 is not reported, it is commonly converted to a ground visibility of about one-half statute mile, with the conversion factor being 1,600 feet of RVR to one-quarter mile of visibility.

Step-by-step explanation:

If the instrument approach procedure for the airport of intended landing prescribes an RVR of 2,400, but RVR is not reported on the runway of intended operation, this RVR minimum would typically be converted to a ground visibility of approximately one-half statute mile.

The specific conversion can vary as it may be dependent on local regulations or the specific aircraft operating manual. However, the commonly accepted conversion factor is that 1,600 feet of RVR is roughly equivalent to one-quarter mile of visibility. Thus, an RVR of 2,400 feet would be approximately one-half statute mile of visibility.
