Flaps & stalling

Just a thought here guys,

I was reading a book titled "Flight Automation", (which i've since added to my christmas wish list) and at the beginnning of the book, it discusses the theory behind drag, lift and angle of attack etc etc...

We all know that when you increase the AOA, that you produce a creater lift coefficient and so climb etc etc, very basically. However more regarding a stalling situation:

When the critial angle of attack (anlge between the relative airflow and the mean chord line of the wing) is met and exceeded, the aircraft will stall.

If you maintain an angle of attack close to the crittical angle of attack, same powerr setting etc, will the aircraft stall if you were to abruptly lower flap?

Technically this increases the mean chord line angle and so i think it should. What do you think?

I by no means accept responcibility for pilots who attempt this! lol

Regards,

Antony
