That anybody could confuse the grey "no go" zones is a bit of a concern.
Putting the dive and drive on that chart shows how complex D and D really is. That is the beauty of the chart; start at 10DME at 3000ft, dial in/set up a 3° slope and miss every limiting step on the way down. But most importantly of all, you can check your progress down final
before you get to any limiting step. In any case, just get on and stay on the Distance/Altitude table and you will 1/miss every limiting step and 2/arrive at the MDA/DDA 2W/2R on the PAPI.

No. Follow the Distance/altitude table until on the PAPI and you will not run into anything. Simple.
