You can take it as you want, guy wanted to know why Citations taxied in with some flaps dangling. Yes the loads are higher in flight and yes you can park the plane flaps up no worries. For most, but not all operators it is SOP to park a 500 or 550 with flaps dangling whether there is truth to why or why not I have no idea, and since I do not fly the airplane any more I don’t really care. As for the 560 I have no idea I never flew it. The company I flew Citations for provided pilot services nationally, of all the operators I was farmed out to maybe 20, only one or two parked the plane flaps up. I have not flown the plane in a long time but still see a lot of them parked with some flaps out.
HAVE A NICE DAY!
