before it stalls. so you do run into that situation. but as long as you re not experiencing a lot of airplane upset in the form of turbulence you re still in an okay situation as long as you re monitoring the power for the airplane and how the systems are operating. you raise an interesting point, because i was talking to a friend and colleague who is an aviation expert in australia, and he made that point. said he d been looking at the radar information that was available and said they were at 36,300 feet and climbing, doing 353 knots and that there were some in the industry who said that was a bit slow. it could have been. i don t want to speculate, especially since i m not an airbus a-320 captain, but that s indeed possible. but i think any of the radar data that we have or any of the data that we have period is just based on ground speed as opposed to airspeed.
