I hear what you're saying. Unfortunately, this isn't what I'm hearing from Jeppesen and the local authorities.

In this particular case, this is a terrain clearance criteria. Secondly, this procedure is designed to take into account the requirement of certain types of aircraft to accelerate in level flight after the initial climb. To accomodate this requirement, an acceleration portion of 6 nm in length is identified. The horizontal portion is followed by a climbing portion with a 1 percent gradient representing the enroute climb until an altitude at which other prescribed obstacle clearances become effective. These 2 portions are constructed so that a minimum clearance of 295 ft above all obstacles in the primary area exists. The minimum acceleration height is not less than 820 ft. The procedure is usually then noted as mentioned: Climb to...(blah blah).

The bottom line is then; if you ignore the given altitude we are discussing, make sure that your company performance section have established that your performance exceeds the limits given above. Further, do not forget that this will usually be covered as a company policy, AND an engine out flight path needs to be established as an alternative means of escape should the DREADED occur.
