Interpretation
The ILS or LOC RWY 16L approach at Washington Manassas/Harry P. Davis Field has temporary amended ILS, localizer, and circling minimums and visibility requirements due to three temporary cranes near the airport. If the local altimeter setting is unavailable, use the Dulles altimeter setting and apply the specified increases to decision altitudes, minimum descent altitudes, and visibility requirements.
