No, Kalium Chloride is correct. Sunrise is at 06:50 local, Wino you’re forgetting that we are on daylight savings time. At 05:40 it is still dark outside, and airport lighting is required. If the PAPIs were illuminated it follows that so were the runway lights. Years ago a National B-727 landed short in Tampa Bay, don’t know what the probable cause was, but believe no fatalities.
