Obstacle Source Information for Engine Failure Procedure at Take Off
Hi All,
I am wondering from where you take obstacle information for take off analysis, especially when designing an engine failure procedure which is not following runway heading or an SID (which you could assume the climb gradient provide 0,8% obstacle clearance).
AIP/AIC/Notam are a required source but not sufficient.
I started using digital data bases like FAA DOF, SRTM... or other paper sources like civil topographical charts (usually used for trekking purposes) when they show additional obstacles or areas not covered in AIP.
I guess you work is on a case by case basis but I wonder what kind of source you use. In addition, if you can share the company policy you are aware of, it would be very helpful.
