Question 1

How do we get ultimate load

Answer 1

Load limit x safety factor

Question 2

Safety factor for normal aviation is

Answer 2

1.5

Question 3

Load limit does not account for mass so always use

Answer 3

heaviest

Question 4

Answer 6

+VE 6.0

-VE -3.0

Question 7

Va is

Answer 7

Highest speed you can give full elevator up deflection and not bend the ac

Question 8

If you are below Va / slower speeds what will happen before the a/c bends

Answer 8

stall

Question 9

Vb is

Answer 9

Design speed for Gusts / turbulence

Question 10

Vra

Answer 10

Used as recommended turbulence airspeed

which is fast enough to avoid stalling + slow enough to avoid structural damage

Question 11

Vc is

Answer 11

design cruise speed
no less than Vb x 1.32
no more than 80% of Vd

Question 12

Vmo

Answer 12

Max operating Velocity

Question 13

Mmo

Answer 13

Max Mach operating number

Question 14

Vne

Answer 14

never exceed

Question 15

Vle

Answer 15

max land gear extended

Question 16

Vlo

Answer 16

Max landing gear operating speed

Question 17

Vfe

Answer 17

Max flap extension speed

Question 18

Gust loads are

Answer 18

the extra load factor caused sudden gust of vertical or horizontal winds

Question 19

For gust loads think of the bad things about a?

Answer 19

glider apart from slow speeds
