All correct from aircraft certification point but:

PANS OPS (ICAO Doc 8168) Vol I:

3.6.1.7 Normally procedures are based on a nominal missed approach climb gradient of 2.5 per cent. A gradient of 2 per cent may be used in the procedure construction if the necessary survey and safeguarding can be provided; with the approval of appropriate authority, gradients of 3,4
or 5 per cent may be used for aircraft whose climb performance permits an operational advantage to be thus obtained. When other than a 2.5 per cent gradient is used, this will be indicated on the instrument approach chart and, in addition to the OCA/H for the specific gradient used, the OCA/H applicable to the nominal gradient will also be shown.
Hence all CAT I missed APCH gradients are 2,5 per cent unless stated otherwise. So no different charts for this reason, correct?
