Interpretation

For Chicago O'Hare International RNAV (GPS) RWY 4R Amendment 1D, the LNAV/VNAV decision altitude is 1,129 feet MSL (HAT 468 feet) with RVR 5,000 for all categories. If the approach lighting system is inoperative, LNAV/VNAV visibility for all categories and LNAV visibility for categories C and D increase to 1 3/8 statute miles. These temporary changes account for cranes southwest and west of Runway 4R reaching 788, 845, and 841 feet MSL.
