Hayward Executive Airport RNAV GPS Runway 28L Approach Explained

Flying Magazine has published a breakdown of the RNAV GPS approach to Runway 28L at Hayward Executive Airport (KHWD) in California. It is used when weather drops below visual meteorological conditions.

The airport has two parallel runways, and this approach is for the left one. After breaking out of the clouds, pilots have to confirm they are lined up with the correct runway unless they are circling.

The approach has several sets of minima. With WAAS, the LPV minima give a glide slope and a decision altitude of 348 feet MSL, which is 298 feet above ground level. Aircraft without WAAS must use higher minimums. On the LNAV MDA, pilots have to follow stepdown fixes starting at the initial approach fix JOBUS. The article does not detail those stepdowns beyond that point.
