When maintaining level flight an increase in speed will

  • cause the C of P to move aft.
  • cause the C of P to shift forward.
  • have no effect on C of P position.

when increase in speed, basically lift increases. so the c of p move forward what!! sorry if i'm incorrect!

ronit_airbus: In level flight CL AND CP are in a straight line. When speed will increase CL will tend to increase, but the autopilot heading hold channel will supply the sensing error signal to the pitch trim motor thereby trimming the nose down attitude due to which the CP willmove aft

When the trailing edge flap is extended

  • CP moves rearward.
  • the CP moves forward.
  • the CP remains stationary.

Regarding the above question the CP moves forward in basic single engine aircraft and CP moves rearward in high speed aircraft where mach tuck happens so the question should specify it?

PART66Online: Hello! As I know, with flaps extended center of pressure moves rearward. But I'm not expert, maybe someone can provide proof link? I googled that and found what this question is very very wide, but basically with extended flaps CP moves rearward.
