During a right or left turn manoeuvre in an aircraft, a partial sideways movement is experienced which is known as
slip
A skidding movement is sideways and outward from the turn. This is known as
skid
The manoeuvre envelope (or VN Diagram) is used to
all of the above
The vertical axis of the manoeuvring load diagram represents
load factor or 'g'
The normal limit not to be exceeded on the load factor scale is called
limit load factor
The CLmax boundary on the manoeuvring load diagram represents
the point at which the stall occurs at various speeds and loading
Which control device is used to aid the rolling of the aircraft by lowering on the up going wing and raising on the down going wing?
Flaperon
What is the main purpose of drag inducing devices?
To decrease lift
What is the function of vortex generators?
To prevent separation of airflow
Which control device destroys lift over a part of the wing and is deployed to allow a rapid rate of descent?
Spoiler
What is the purpose of stall wedges located on the inboard leading edge structure of the wing?
To prevent stall
Which device is used to prevent air from flowing toward the wing tip?
Fence
Which of the following is true about high lift devices?
High lift devices allow for lower take-off and landing speeds.
What is the purpose of slats in leading edge devices?
To increase the lift produced by the wing.
What is the function of slots in leading edge devices?
To improve the airflow conditions at high angles of attack and slow speeds.
What happens to the slat during landing?
The slat extends further into the air flow
What disadvantage can be overcome by making the slot movable?
Increased drag at high angles of attack.
Which group do high lift devices belong to based on their location on the wing?
All of the above
Which type of flap is mainly used in areas where there is no room to use a slotted flap, such as around the pylon to wing area?
Kruger Flap
What is the purpose of wing flaps during take-off?
Increase lift with little increase in parasite drag
What is the purpose of having higher lift producing flaps located on the inboard trailing edge of large transport category aircraft?
To prevent over stressing of the wing
Which type of flap increases the effective area of the wing and lowers the trailing edge by rolling back on a track?
Fowler Flap
What are flaperons?
Flight controls that act as both flaps and ailerons
On which aircraft can the function referred to as 'aileron droop' be found?
A320 and A330
Which of the following is true about the VA design manoeuvring speed?
It is the maximum speed at which the aircraft can be manoeuvred to the g limits without damaging the structure.
What is the design cruising speed?
It is the selected speed by the manufacturer that includes a margin to prevent exceeding the maximum speed.
What happens when an aeroplane pulls up so quickly that the angle of attack exceeds the stall angle?
The laminar airflow separates from the surface of the aerofoil.
Which control device destroys lift over a part of the wing and is deployed to allow a rapid rate of descent?
Spoiler
What is the purpose of vortex generators?
To prevent separation of airflow
What is the function of a slotted flap?
Generates drag to help slow down the aircraft.
