It seems that Simbrief doesn’t correlate the planned altitude with both the surface and limitations of SID. It generates a plan for 7000’ via a SID that has points over 11000’.
Also, suggests a 7000’ when the mountains flying over are 10000’ high.
Example : DA62 , LOIH to LOSM. No SID here but definitely flying into the mountains. (suggesting 7000’ which is below the terrain height).
