One last question... On the 10-9A for CLT it has the Obstacle DP. Those numbers are different than what's on some of the SID's. I'd assume we'd follow the ODP, then when you are beyond the restrictions, continue with the SID, correct? Why don't they just change the SID to match the ODP?
Thanks as always guys.
CLT tower/departure could file a course deviation on you if you did that.
Fly the SID and not the ODP, SIDs provide obstacle clearance just as ODPs do. The SID is different than the ODP because it's designed by ATC for traffic flow while still providing obstacle clearance. ODPs are used when you're not assigned a DP/SID by ATC, but airlines usually don't follow generic charted ODPs because they have OPS specs allowing for a special company specific DP in lieu of a generic charted ODP.
