Answer 16

EBF concept for powered lift is based on extending flaps into the engine exhaust to interact/deflect the exhaust stream downwards

Converts engine thrust to lift

Question 17

Backside approach meaning

Answer 17

With powered lift, thrust controls flight path angle and aircraft attitude controls speed

Question 18

Winglets purpose:

Answer 18

Winglets reduce wingspan for same amount of lift, they reduce drag and improve cruise performance

Question 19

Strakes

Answer 19

Nacelle strakes improve wing aerodynamics and fuselage strakes reduce cruise drag, cruise performance is then improved
