Q

Flaps on a helo

A

Leading trailing edge

Helo makes extra lift

16
Q

Spoiler

A

Decrease wing lift

17
Q

Speed brakes

A

Hinged surface used to reduce speed

18
Q

stats

A

Located on leading edge improve lateral control at low air speed

19
Q

Collective

A

Rotor blades change collectively to change angle of lift

20
Q

Angle of attack

A

Angle airfoil or fuselage meet air

Measured in units

21
Q

Autorotation

A

Let’s helo land safely wo using engine power

22
Q

Basic aircraft hydraulic system

A
Reservoir to hold hydraulic fluid
Pump to move fluid
Tubing to transmit fluid
Selector valve to direct flow
Actuating unit to convert fluid pressure into useful work
23
Q

Landing gear component

A

Shock strut assembly absorb shock
Tires lets plane roll
Wheel brake assembly Slow and stop plane
Retracting and extending mechanism puts out landing gear
Side strut and support Gives Strength/support for landing gear
