HN39 - I am addressing what to do upon entering ALT 2 with no airspeed indication. Once in a stall first course on the table is admit you are stalled. Second course is nose down with an urgency depending on rate of drop of altitude. Third course is airspeed. Fourth course is a gradual pull up once airspeed is high enough. Fifth course is the dessert of moving back to planned course.
If no airspeed continues use AoA vane as a clue whether you are stalled or not. When it "agrees" with pitch you're good to pull up - gradually. No AoA report in the cockpit? Um, Er, Ah, Boss - you're gonna die?
