Flight spoilers are primarily used

with differential ailerons to reduce adverse yaw in a turn.

The rudder limiter reduces rudder travel at high speeds in order to prevent

rudder/stabilizer overload.

A servo tab is

connected directly to the pilot's control and moves the control surface to which it is attached aerodynamically

Control surface bias may be provided on one or more control surfaces to

make an aircraft oppose a constant disturbing force such as propeller slipstream.

On aircraft fitted with spoilers for lateral control, a roll to the right is caused by

right spoilers extending, left spoilers remaining retracted.

If the leading edge of a variable incidence stabilizer is moved downwards, there will be a

nose up moment on the aeroplane.

Flaperons

provide higher lift at low speed or roll control, or a combination of both.

Lift dumpers are used

after touchdown only.

A saw tooth leading edge

helps to prevent spanwise flow of the airflow across the wing.

Spring tabs provide

an aerodynamic assistance to movement of the control surfaces at high aircraft speeds only.

On an aeroplane fitted with inboard and outboard ailerons, the outboard ailerons are

ineffective at high speed.

An aerodynamic balance tab control rod

is not connected to the control surface.

The leading edge of an all moving tailplane goes down causing

the aircraft to pitch up

The Critical Mach No. can be increased by

sweeping back the wing.

A detrimental factor affecting the airflow in engine intakes of high speed aircraft

is formation of shockwaves.

To counter the effect of a shift of centre of pressure as an aircraft flies through the transonic region, fuel is pumped

backwards

Area rule' is a design feature sometimes used to

reduce drag at transonic and supersonic speeds.

The increase in skin temperature, due to aerodynamic heating, of a high speed aircraft is approximately proportional to

the square of the aircraft speed.

The ailerons are rigged so the one moving upward will travel farther than the one moving downward is called

differential ailerons.

Control surface that used to disrupt airflow over the wing is

spoiler

The ratio of speed at an aircraft to the local sound speed expresses the

mach number.

The purpose of a slot in a wing is to

act as venturi, accelerate the air and re-energise boundary layer.

will increase wing area and camber.

Fowler flap

A leading edge slat is a device for

increasing the stalling angle of the wing.

A factor of great importance in the study of high-speed flight is the

speed of sound

When tension exceeds the elastic limit of a material it will

remain permanently deformed

the slat that is permenantly extended is called

fixed

Elevons are fitted to the…………of the left and right wings of delta winged aircraft.

trailing edge

Imaginary axis that goes vertically through the aircraft is

normal axis.

The speed of sound is very important in aviation and depends

solely on the temperature
