SAAB Pilot question

Is it true that the addition of flaps on the SAAB causes an increase in Vmc?

Well with flaps comes drag, So I would think that it would decrease Vmc. But to much flaps and its bad no matter what... You might be decreasing Vmc but the Drag will KILL you.

One thing I always liked about the SAAB was the Flap Blowback, we called them autoflaps heheh I think is was like 22000psi so once it had less than that they came down, or somethin like that.

Have you ever flown a twin? Same aerodynamic factors affect all twins in the same way.

Second that, everything that I was taught says that no matter what plane you are flying the addition of flaps increases Vmc.

flaps vs Vmc question

There is also the "induced lift" thing to consider, no? With an effective increased camber when flaps are down (to a degree), lift will be increased. When that happens, one needs MORE aileron towards the good engine to counter roll. Increasing Vmc would be an adverse condition, (IMHO) due to an increase in induced lift of the propwash over the wing.

Ain't that the truth. You'd think that they could have had something similar installed on the CRJ200. Total pain in the arse tweaking thrust levers whilst hurtling down the runway...

Show me proof of that... i can guarantee you that you wont find a single FAA document stating your position. Heard it from a mesaba Saab captain once, just wanted to see if any had anything different to say,
