John:
Thanks for the reply. Just to get it straight - these procedures are created by first looking at the performance factors - gradients & obstacles - then they are run by ATC to insure that they don't interfer with traffic conflicts - making sure they don't run through any adjacent traffic patterns, etc. ?
This may sound elementary - but because the Take Off phase of flight only goes to 1500' AGL - would these procedures only pertain until the A/C has reached that altitude.
Thanks for your continuing informative reply's
