FAR 25 approach climb gradients for TERPS IAPs may be simply implied within the chart...similar to second segment limitation [a certification standard]---it might not say explicty, but implicit within other charts with an annotation such as "cross hatched area -does not meet approach climb limits" however for certain special cases it is up to the airline operation to meet FAR-121 and gain at least an equivalent level of safety as an engineering goal...altogether the TO case MUCH more difficult to meet than any other from what I've learned here from the performance engineers...
With regards to the IPH it's a very good publication aloowing pilots to better understand TERPS criteria and the NAS
Zeffy I'm in that thread...
