When you know the history of AF447 and (as far many saying) formation - training of new pilots it seems that strict limits are needed
If they had been strict in AF447 .. Hall could have said in reaction to SS command to climb :
I dunno our speed ... but ..
Your throttles are set at VVV
The weight of the aircraft is XXX
The current altitude is YYY
The temperature is WWW
The CG is located at ZZZ
If you want climb now you're going to put us in a very dangerous situation that's why I will limit your ability to climb
Will give you update ASAP
