Makes an interesting discussion. Especially since almost everybody flies these types of SID's and Missed Approaches every day, without giving them any thought. We all just fly these acceleration segments the way we feel, or the way our own logic tells us is correct.
In the Jep Air Traffic Control section, on pages 236 and 237, is an extract from the Flight Procedures (Doc 8168) Appendix 1 - Acceleration Segments. After reading this document, it is clear that the note "Climb to ....(altitude/height) prior to level acceleration" is only used in the terrein clearance instance. This IS NOT a noise abatement procedure.
MY LOGIC, (which too may be wrong) tells me that a V2 plus 10 (all engines) or V2 (engine out) climb is required until passing the specified altitude!???
Anybody else care to comment, or does anyone have a more specific knowledge on this subject???
