1) What is the purpose of the aircraft's ground spoilers? Report

The two outboard spoilers are ground spoilers, causing induced drag to slow the aircraft down on landing.

The ground spoilers operate in conjunction with the flaps using the induced drag to slow the A/C down after touch down.

To reduce lift and increases the aerodynamic drag after touch down.

2) At lower aircraft speeds the ailerons and spoilers on one wing, on most aircraft, will Report

Be locked out to prevent movement.

Be in use together.

Operate differentially (opposite directions)

3) Spoilers are hinged at the leading edge of their panels and are located Report

On the upper surface of the horizontal stabilizer's surface forward of the trailing edge

On the lower surface of the wing, forward of the trailing edge

On the upper surface of the wing, forward of the trailing edge

4) Spoilers on modern transport aircraft are designed to deploy Report

Downwards only

Upwards only

In either direction

5) Spoiler panels may also be referred to as Report

Speed brake panels

Slots

Diffusers

6) In the flight mode, when aileron control is commanded about the longitudinal axis, the spoiler on the down-going wing will Report

Raise

Lower

Remain flush with the wing's surface

7) What position on the speed brake cockpit control lever will provide for maximum spoiler panel deployment after landing? Report

Down

Armed

Up

8) Spanwise airflow across wings can be reduced by fitting Report

Winglets

Wing fences

Vortex generators

9) Vortex generators are used to prevent stalls caused by Report

Excessive angle of attack

Shock-induced separation

Turbulent atmospheric conditions

10) The lift/drag characteristics of an aircraft are controlled by the Report

Secondary flight controls.

Primary flight controls.

Airbrakes and liftdumpers.

11) Trim tabs are used to Report

Assist flap movement

Control a spoiler input

Alter the camber of primary flight control surfaces

12) A balance tab: Report

Moves in the same direction to the control surface

Deflects in the same direction as the control tab

Is controlled by the aircraft trim system

13) The purpose of the spring tabs is to: Report

Assist the pilot in moving the control surfaces

Contribute to the static balancing of the control surfaces

Make in-flight trim adjustments possible

14) Trim tabs Report

Are moved by the control wheel and rudder pedals

May be fitted to any of the primary flight control surfaces.

Perform the same function as balance tabs

15) Which way does an anti-servo tab move, relative to the control surface that it is fitted to? Report

In the opposite direction

It does not move, it is fixed

In the same direction

16) An adjustable trim tab on the elevator, can Report

Be adjusted by bending the fixed tab

Trim the aircraft so it will fly hands-off, at any airspeed

Also be called an aerodynamic balance panel

17) A fixed trim tab on the rudder Report

Can be adjusted by the pilot in flight

Can be adjusted by the movement of a jackscrew

Is bent so it will deflect the rudder to compensate for an out of trim condition

18) The spring of a spring tab is compressed at Report

High airspeeds

High altitudes

Low airspeeds

19) Fixed trim tabs Report

Cannot be adjusted

Are adjusted by trial and error

Can be adjusted in flight by the pilot

20) Incorrect rigging of the elevator trim tab will affect the balance of an aircraft about its: Report

Lateral axis

Longitudinal axis

Vertical axis
