Why is there a nose-up change in moment after leaving ground effect?
Asked by: Lemontree 3596 views General Aviation
The Airplane Flight Handbook states:
The aircraft leaving ground effect will
1) Require an increase in AOA to maintain the same CL
2) Experience an increase in induced drag and thrust required
3) Experience a decrease in stability and a nose-up change in moment
4) Experience a reduction in static source pressure and increase in indicated airspeed
I'm having a hard time understanding the number 3 here. What's the aerodynamical reasons you experience a nose-up change in moment right after leaving the ground effect?
