I thought it was sufficent to just push the ident button when asked to ident, but from now on I will comply with CAP 413
A previous post referencing 413 said we should state the initial SID required level when checking in on a stepped climb SID along with the passing level and SID designator. I thought that this was only required when ATC have modified the SID...ie maintain 3000'. How else do we communicate the difference when the two levels are the same (they usually are in my experience).
Hope this makes sense
