JJFFC:
1/ a pilot nose up
2/ he stalled his plane and didn't alert the captain nor did he communicate
3/ he didn't recognize his fault although his instruments gave him all the necessary information (the lack of speed data is a consequence of the stall not the cause)
Is it your position that the airspeed indicators did NOT react to ice on the pitot tubes?
I play golf : every 3 month I need 3 hours of practicing my 3 iron to be able to do something with it.
To pilot is a sport : it needs training and training and training.
That's why there are captain and cadet. Champions and losers.
I play golf as well, and still use my 3 iron. The 1 and 2 iron have been retired.
Yes, one needs practice to stay proficient.
