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.
1. The certification process dwells extensively on the balanced runway and the takeoff flight path.
2. Every flight has a takeoff. And, often above max landing weight; perhaps well above.
3. Missed approaches occur on a small percentage of flights. If an engine becomes inoperative during the flight, often the IAP with a missed approach performance problem can be avoided.
4. There is no "takeoff" flight path defined in certification for the missed approach flight path.
Related to both the takeoff flight path and the missed approach flight path is the lack of clear, concise guidance on how to get from the end of the takeoff flight path safely into the en route structure, especially in mountainous areas.
