TO perf

[ppppilot]

Hello Vsplat.
I have been rereading your post.
As you said, there is a proliferation of exigent SID, mainly because of noise abatement. What I see there is that the number of exigent SID because of obstacle clearance is also growing up, but not at the same rate that new airplane models improve their performances. I would say better, “TO performances are decreasing on new models, in the name of costs and fuel savings, while SID’s climb requirements are increasing”. And we pilots are performing blind TOs.
Reducing the number of engines of the airplanes, thus reducing the power and increasing the risk on extended over water operations, to save costs. Increasing the precision requirements on altitude and vnav, to increase the traffic potential. Going to the limits with the TOW, thanks to better soft and hardware in use today.
I agree we are getting better in technique and that is good for all of us. But the balance field is clearly falling to the money side, against safety and there, passengers and pilots are loosing. Long time ago, flying was a public service. Today the trend is to become a mountain of numbers.
I believe neither impossible nor too expensive, to have rules and systems to determine the TOW more precisely and safely as we have discussed in an earlier post

I am only asking to increase the safety at the same speed that precision does. Thanks to pprune we can discuss on that.
