Load Factor - Answer-ratio of the total load supported by the wing compared to the weight of the
aircraft. Also commonly known as "G force".
Load Factor Equation - Answer-load supported by wing/total weight of aircraft
Positive Static Stability ...
benefits of low wing - Answer✔✔-Easier to build strong landing gear support
Better roll maneuverability (less lateral stability)
Shorter take off distance
Ground Effect - Answer✔✔-Air gets trapped under wing causing high static pressure and more lift close
to ground, good for take off bad for landing
Is high or low wing more stable and why? - Answer✔✔-high wing, lift is above CG
benefits of T tail - Answer✔✔-Keeps air flowing near rudder at high AOA and air flowing over elevators at
low AOA. Also gets horizontal stab out of the way of engines and makes planes seem bigger
drawbacks of T tail - Answer✔✔-more weight on top, more structure needed
Benefits of v tail - Answer✔✔-decreases interference drag, pressure drag and skin friction drag and even
reduces radar detection
benefits of biplane - Answer✔✔-short wings good for fast rolls
Flying wires - Answer✔✔-transmit lift back to fuselage
landing wires - Answer✔✔-transmit downward impact of landing from wings to fuselage
Interplane struts - Answer✔✔-transmit lift between top and bottom wing
cabane struts - Answer✔✔-transmit lift from wing roots to fuselage, also support wings when they don't
connect to fuselage
stagger - Answer✔✔-when wings are not directly above each other
