We’re all on the same page, our discussion is for those aircraft that can but are not certificated to do so. I suspect we here have been doing this for a long time anyway but we need to go one step further.
We need to take leafblowers claytons part 35 and decide as an industry with casa support what is in and what is not. For example we can leave the 1st segment out since it’s not practical, accept that if you reject a takeoff on a 1200 metre runway at close to V1 you are almost certainly going to run off the end and focus on what you do should that happen.
Keep the 2nd and 3rd segments, use 1.6 to 2.4 percent gradients, understand weight and temperature limits to achieve that, include either a curved departure or a single turn after cleanup at 400 feet onto an obstacle clear flight path to lsalt/msa, understand how to create such special procedures. Google earth in 3D is a beautiful thing for that purpose. Understand how that turn is conducted.
Understand how many track miles it takes to get to just 1500 feet over a 1.6% gradient. (12 to 15 Nm) and what you do from there, return or go somewhere else.
Hands up all those single pilot turbine drivers that read this with more than a passing glance.
