Update SOPs??
If you cant maintain altitude, then you cant maintain...! What do you want the guy to do? Update the SOPs to read: Dont descend even though the aircraft is unable to maintain!!
We had a CRJ2 lose an engine and he immediatly lost 3000ft until he managed to hold FL254. He didnt bother descending any further to make it a round flight level, because I guess every foot of altitude proves its worth if the other engine should decide to give up too....
