M08 P2

'Load factor' has the following meaning:

• The ratio of a specified load to the mass of the aircraft the former being expressed in terms of aerodynamic and inertia forces

• The ratio of a specified load to the mass of the aircraft, the former being expressed in terms of aerodynamic forces, inertia forces and ground reactions

• The ratio of a specified load to the weight of the aircraft, the former being expressed in terms of aerodynamic forces, inertia forces and ground reactions

Which of the following are lift increasing device?

• Flaps only

• Slots only

• Flaps and slots

A boundary layer fence on a swept wing will

• improve the high speed characteristics

• increase the critical Mach Number

• improve the low speed characteristics

A deployed slat will

• increase the camber of the aerofoil and increase the effective angle of attack, suction peak so that Clmax is reached at higher angle of attack

• increase the boundary layer energy and increase the suction peak on the fixed part of the wing, so that the stall is postponed to higher angle of attack

• increase the boundary layer energy, move the suction peak from the fixed part of the wing to the slat, the stall is postponed to higher angle of attack

The type of flaps which increase both lift and area of the wing is a

• slotted flap

• plain flap

• Fowler flap

What happens to lift when flaps are lowered?

• Decreases

• Remains same

• Increases

In a gliding flight

• lift is greater than weight

• lift is less than weight

• lift is zero

A slotted flap will increase the CLmax by

• increasing only the camber of the aerofoil

• increasing the camber of the aerofoil and improving the boundary layer

• increasing the critical angle of attack

A stall warning device must be set to operate

• at a speed just above stalling speed

• at a speed just below stalling speed

• at the stalling speed

A stick shaker is intended to come into operation

• prior to the actual moment of aircraft stall

• at the actual moment of aircraft stall

• immediately after the aircraft is stalled
