All goods advice here. The best advice though is don't dept if ya can't come back for a ldg due terrain or wx. The reverse use of a DGA is great if available. Circle whilst in the ct area obviously simple & effective. Another trick is to use the opposite rwy compared to yr dept trk if avail. WX conditions allowing that is.
Say yr dept trk is 180 & you have 36 avail for dept. Dept off rwy 36 & by the time you get to the circuit limit for say Cat B (2.66nm) you may very well be abv LSALT already. If rdr is avial ask for rdr MVA whilst climbing.
I've even gone the opposite way to my intended dpet trk where the LSALT is much lwr then once I reach my LSALT for my intended trk minus an allowance for the 180 turn & miles already completed turn & set course:-)It's the same as staying in the Ct in a way but ya might get visual going the other way & be able to proceed visually abv cloud.
At the end of the day simple really,don't crash!
