This goes to the heart of what I have been asking.

So if I use one of the "public" plates, then I just need to achieve 2.5%? I assume that will give me 35ft obstacle clearance up to the MSA. I can...

How does the crew know what weight they can do the approach at and still successfully complete an EO Missed Approach up to the MSA/LSALT?

Repeating my earlier question, what terrain clearance do you provide in the missed approach procedures you design, or do you put the "required" gradient on the chart?

Do the designers honestly believe that increasing the vis requirement to 1nm (less than the length of a runway) is going to enable a satisfactory visual terrain avoidance manoeuvre after takeoff? In...

The irony of it all. Micrometer management of the takeoff situation, with no "requirement" at all to ensure terrain clearance in a Missed Approach apart from the WAT limit. :confused:

So it's left up to Capt and FO Bloggs to work it out themselves. How are we going to do that, given only some basic graphs in the AFM? I know that if I am below the APPR Climb weight we'll do the G/A...

For a start, the AFM requires the aircraft to be able to climb at 2.1% in the Approach-climb config at the airfield elevation, so that is the immediate go-around taken care-of.

I understand all that. The fact is that, at least in the vertical sense, the terrain clearance of 2.5% provided by a SID and most Missed Approach procedures is in excess of the OEI performance...

That's different. In your first post you only mentioned "EOSID" which implied you were using the takeoff EOSID and RTOW for the Missed Approach.

If your EOSID charts specifically mention limit...

No it's not. The 2.5% is merely what your aircraft needs to achieve to miss the obstacles on the Missed Approach path. Nothing more, nothing less. If your aeroplane will not do that (eg with an...

I wouldn't be so sure about that. The 717 (not the most underpowered thing in the sky) is a real dog hot n high on one engine and the 2.5% MA gradient is quite limiting sometimes.
