قائمة الأسئلة

Which point on the aerofoil is represented by number four

Separation point

What pattern can be found at the stagnation point?

Stream lines are divided into airflow above and below the profile

Compared to trailing edge flaps ,leading edge devices like slots

produce less drag while allowing a higher angle of attack

Which type of boundary layer does the figure show?

turbulent boundary layer

Which kind of drag contribute to total drag

induced drag and parasite drag

A statically unstable aeroplane

becomes more stable with a rear centre of gravity

Point number one in the figure indicates which flight state

inverted flight

Which point on the aerofoil is represented by number three

transition point

Which point on the air foil is represented by number one

Stagnation point

Which constructive feature provides longitude stability to an aeroplane in normal configuration (empennage at tail)

Downforce at the elevator

The right alieron deflects upwards the left downwards how does the aircraft react?

Rolling to the right yewing to the left

During a descent, at idle Power with constant speed the Propeller lever is moved backwards. How do the propeller pitch and sink rate change?

propeller pitch is increased sink rate is decreased

During straight and steady climb which force acts additionally and in the same direction as the drag force resulting in more power required for climb then horizontal flight

A component of the weight force along the rearward flight path

The position of the center of pressure at a positively shaped profile

moves to the trailing edge while the angle of the attack become smaller

Which statement about the airflow around the aerofoil is correct if the angle of attack decrease

The centre of pressure moves aft

Which statement concerning the angle of attack is correct?

A too large angle of attack may result in a loss of lift

Induced drag is generated

at the trailing edge of the wing

What structural item provides lateral stability to an aeroplane?

wing dihedral

Minimum drag

The bank in two minutes turn (rate one turn) depends on the

TAS

Which constructive feature is shown in the figure?

Latteral stability by wing dihedral

The elevators moves an aeroplane around there

Latteral axis

Balance around the latter axis is achieved by the

horizontal stabilizer

Number three in the drawing corresponds to the

Camber line

The start of the vortex development is created during which phase of flight

when lifts is being generated during rotation

Which statement about the airflow around the aerofoil is correct if the angle of attack increases

the stagnation point moves down

If you double the airflow speed, how does the parasite drag coefficient changes?

It does not change

The elevator deflection during takeoff rotation

Is increased for a front centre of gravity
