Maybe us Boeing pilots should have some kind of warning when an Airbus is approaching us in the clouds at high altitude in RVSM airspace that the Airbus below you if losing IAS will by procedure fly through your altitude because of their procedures.
5 degrees nose up and climb power will definately take your aircraft out if you are not lucky enough to be not in their trajectory. AF 447 went through 3 altitudes to finally stall. Thank God no aircraft were there. AB, join the rest of the universe and in level flight just stay level and do the check list, don't fly through other airliners altitudes because mid air collisions can be dangerous. If your altimiter works use it, don't be stupid because AB said to do it. The procedure at the top of the checklist says to use it if you need to for safety of flight. Level at FL 350 it was not necessary, just set or leave power what it was and maintain attitude 2.5 to 3 degrees nose up and do the UAS checklist. Remember, we are not robots following every procedure because we also are pilot who know how to fly an airplane. Maintain altitude if your altimiter is working and do the simple check list.
