Thanks for the replies.Top bunk if the published sid holds me to an initial block alt,that is my first level,fine.However the sid may have dme step alts initially alt 4000,15 dme xxx alt 5000.If you as the controller are so busy that my initial call is acknowledged but no further instuction is given to me and i pass the dme xxx point are you expecting me to climb or remain at the initial block altitude and wait for a call.
