CRJ7/9 Flap Positions and Uses
Can one of the CRJ fliers out there clarify this for me:
What are the (typical) uses of the various flap positions on the CRJ7/9?
My understanding is that 8 is normal takeoff, 20 is short field takeoff, 30 is approach, and 45 is landing.
Is 1 used for anything except as a brief pause during acceleration?
Is any flap position typically used for holding or extended approach?
What is typical takeoff for the 9?
Is 30 ever used for landing?
And, you know, anything interesting that comes up in the discussion.
Cheers.
