Have just another question: why on NPA charts some approaches uses Apt Elev and Rwy:


and some uses only Apt Elev:


For precision approaches Rwy is always used for minima calculation. But pictures above confused me for non-precision stuff.

For straight-in minimums, precision or non-precision the Touchdown Elevation is used. For approaches with only circle to land minimums airport elevation is used.
