On a swept wing aircraft if both wing tip sections lose lift simultaneously the aircraft will
- yaw uncontrollably.
- pitch nose up.
- pitch nose down.
Explanation
On a swept wing the tip sections lie aft of the centre of gravity, so when both tips lose lift simultaneously the centre of pressure moves forward. This forward shift of lift creates a nose-up pitching moment. The behaviour is symmetric, so it produces pitch rather than yaw, and the direction is nose-up, not nose-down.
tijaku asking:
loss of lift = nose drop, how come in this case it's not so?
thx

Hello!
Not all sections of the wing loses lift in this situation. Only wing tip section loses lift. Swept wing tips located closer to the tail than other section of the swept wing. As a result aircraft's nose will pitch up in this situation.
Thank you for question.
