stability and control

#28. The centre of Gravity of an aircraft is found to be within limits for take-off:

• Athe C of G will be within limits for landing
• Bthe C of G for landing must be checked, allowing for fuel consumed
• Cthe C of G will not change during the flight
• Dthe flight crew can adjust the CG during flight to keep it when acceptable limits for landing

#30. The property which tends to decreases rate of displacement about any axis, but only while displacement is taking place, is known as:

• Astability
• Bcontrollability
• Caerodynamic damping
• Dmanoeuverability

#12. With flaps lowered, lateral stability:

• Awill be increased because of the effective increased of dihedral
• Bwill be increased because of increased fit
• Cwill be reduced because the centre of lift of each semi-span is closer to the wing root.
• Dwill not be affected
