about CAO 20.7.1b
O_S and J_T,
With no intention to divert the thread, can I throw in the following:
My understanding of the meaning of paras 12.1B and 12.4 is that the planning must go to either MSA if there is no navaid or the enroute OCA (1360'?) in the safety height containment area where there is a navaid.
I also understand that AIP is only a place to publish the effect of proper legislative instruments and cannot mandate anything in its own right. Any statement in AIP about takeoff performance and obstacle clearance would only be based on the regulators view of the effect of CAO 20.7.1b or any amending instruments.
Stay Alive...
