Thank you very much Slasher. That is very kind of you.
I must say a couple of things.
I am not talking about single engine procedures. Only about how much weight can you accept to clear the obstacles in an all engines running SID.
You said that your rwy analysis covers all the obstacles for that rwy. But I am not sure of that.
I use to fly with the best runway analysis software. I have also worked with Flygprestanda charts. If you go to their web you will see that obstacles to analyze are optional to the companies. Sorry for my English. I explain it better. Flygprestanda gives you a solution just in case of an engine failure only up to the diversion point, of the scape path that they suggest for that rwy and the current SID you are flying. Further analyses on the obstacles along the particular SIDs up to the TO final segment with all the engines running are optional to the costumer.
In fact, probably you have noticed, that you only have one rwy analysis chart on each rwy, not on each SID. If different gradient SIDs would be covered in only one chart, the company would be loosing cargo load potential on the less gradient SID.
May be that you have been using, several rwy analysis charts for the same rwy, grouped into same performance requirements. If that is not the case. How do you make your weight calculations to comply with those requirements?
Thank you again.
