SIDs and the MSA
Heres a scenario.
Initially cleared on an SID.
On taxi ATC say " Disregard the SID , after departure route direct to XXX "
MSA in the direction of the new waypoint is 3000ft.
Do you need to track straight ahead till 3000ft or are ATC responsible for ensuring your new departure will keep you safe.
PS there was no omnidirectional procedures in the Jeppys.
Thanks
