Narrative:

I have flown with some crews who seem inclined to make up their own obstacle clearance altitude even though there is a published single engine procedure. These crews like to look at the approach plate for the opposite runway and look for obstacles. At santiago, chile, recently, a crew picked 1500 ft. Eventually I convinced them that the published procedure is safer to level off at 800 ft and then climb at maximum angle to 9000 ft gives you a better climb profile than to level off at 1500 ft and then climb especially when there is terrain along the single engine route at and above 1500 ft. In south america, it is important single engine to get to maximum angle to climb sooner, even though you have to level off at 800 ft afl or 600 ft afl. Please get the word out on this one like you have been doing with other safety issues thanks.

Title: ARPT SITE CHARACTERISTIC TERRAIN - SOME FLCS ARE APPARENTLY CREATING THEIR OWN SINGLE ENG OBSTACLE CLRNC PROC EVEN THOUGH THERE ARE PUBLISHED PROCS. THE RPTR POINTS OUT 1 EXAMPLE OF THIS DANGEROUS PRACTICE.

Narrative: I HAVE FLOWN WITH SOME CREWS WHO SEEM INCLINED TO MAKE UP THEIR OWN OBSTACLE CLRNC ALT EVEN THOUGH THERE IS A PUBLISHED SINGLE ENG PROC. THESE CREWS LIKE TO LOOK AT THE APCH PLATE FOR THE OPPOSITE RWY AND LOOK FOR OBSTACLES. AT SANTIAGO, CHILE, RECENTLY, A CREW PICKED 1500 FT. EVENTUALLY I CONVINCED THEM THAT THE PUBLISHED PROC IS SAFER TO LEVEL OFF AT 800 FT AND THEN CLB AT MAX ANGLE TO 9000 FT GIVES YOU A BETTER CLB PROFILE THAN TO LEVEL OFF AT 1500 FT AND THEN CLB ESPECIALLY WHEN THERE IS TERRAIN ALONG THE SINGLE ENG RTE AT AND ABOVE 1500 FT. IN SOUTH AMERICA, IT IS IMPORTANT SINGLE ENG TO GET TO MAX ANGLE TO CLB SOONER, EVEN THOUGH YOU HAVE TO LEVEL OFF AT 800 FT AFL OR 600 FT AFL. PLEASE GET THE WORD OUT ON THIS ONE LIKE YOU HAVE BEEN DOING WITH OTHER SAFETY ISSUES THANKS.
