I was looking at the picture below and was wondering about the Kruger flap configuration set for landing.
This KLM 744 has landed with only the outboard Kruger slats deployed. Why would'nt the mid and in-board sections be deployed?
Obviously the a/c is still travelling fairly fast as shown by the spray, and too early to retract the flaps.
What kind of performance would the 744 have in this configuration? Is this a normal practice for KLM or any airlines? I ask because I have never seen a plane land or takeoff with only a partial flap/slat setting.
