Never said
it did any planning....and if you are going to use the info for your emergency descent then let me know who you work for and I will avoid flying with your airline.
As has been pointed out to you twice, it is all about SA. With a chart out it is easy to decide which way you are going to turn (if at all) and what level you are going to descend to in order to stay above the highest MSA in your immediate vacinity, and then to monitor your track to an area of lower MSA, knowing when it is safe to descend further. Of course, with your up to date SA you would have already checked and have to hand your Oxygen Escape Chart for the area, tuned suitable navaids to give raw data fix position if needed and have checked the winds and surface temperature and applied suitable add-ons to the area MSA to avoid having to respond to your EGPWS.......now you would have done all that wouldn't you?
