What are the aircraft axis? (select all that apply)
Longitudinal
Lateral
Rudder
Normal
What are the primary flight controls? (Select all that apply)
Rudder
Aileron
Flaps
Elevator
The aircraft _______ about the lateral axis
Rolls
Yaws
Dives
Pitches
To roll the aircraft how would you manipulate the controls?
Move the control column forward and aft
Lower 2 stages of flap
Press left/right on the rudder pedals
Move the control column left/right
The controls use ____________ to create a reaction force
Deflection of air
Reflection of air
Affection of air
Confliction of air
The ailerons control the aircraft in?
Yaw
Roll
Pitch
Speed
To roll the aircraft left how will the ailerons be deflected?
Left aileron will move down and the right aileron will move down
Left aileron will move up and the right aileron will move up
Left aileron will move down and the right aileron will move up
Left aileron will move up and the right aileron will move down
What is the secondary effect of roll
Further roll
Pitch
Slip and yaw out of the turn
Slip and yaw into the turn
If an aircraft experiences unwanted yaw to the right:
The aircraft will gain speed due to a increase of drag
The aircraft will slip and roll to the right
The aircraft will skid and then roll to the left
The aircraft will skid and then roll to the right
In a uncoordinated roll the aircraft will:
Pitch up. This is called adverse pitch
Tend to roll in the opposite direction. This is called adverse roll
Yaw out of the turn. This is called adverse yaw
Yaw out of the turn. This is called adverse roll
What type of ailerons are used to counter adverse yaw?
Select all that apply
Friese Ailerons
Coordinated rudder
Wooden ailerons
Differential Ailerons
Two aircraft of the same type perform a 30° turn. Aircraft 'A' is traveling at 60 knots and aircraft 'B' is traveling at 120 knots. Select the correct statement
Aircraft 'A' will have to move the controls further than aircraft 'B' to achieve the same roll. Aircraft 'B' will have increased control effectiveness
Aircraft 'B' will have to move the controls further than aircraft 'A' to achieve the same roll. Aircraft 'B' will have increased control effectiveness
Both aircraft will have to move the controls the same amount.
Aircraft 'A' will have to move the controls further than aircraft 'B' to achieve the same roll. Aircraft 'A' will have increased control effectiveness
What parts of the aircraft does slipstream effect?
Select all that apply
Tailplane
Elevator
Rudder
Ailerons
How do you increase slipstream?
Fly Faster
Fly Slower
Higher power setting
Lower power setting
Trim tabs:
Relieve control pressures. If back stick pressure is required, move the trim wheel forwards
Relieve control pressure. If forward stick pressure is required, move the trim wheel backwards
Increase control pressure. If forward stick pressure is required, move the trim wheel forwards
Relieve control pressures. If forward stick pressure is required, move the trim wheel forwards
To hold a control deflected in the desired position the trim tab will move.
In the same direction as the main control
In the opposite direction as the main control
Will always remain inline with the main control
What are the two types of control balances we are concerned with?
Mass and lateral balances
Mass and longitudinal balances
Mass and aerodynamic balances
Mass and normal balances
What is the purpose of mass balancing?
Eliminate flutter by moving the CoG of a control closer to the hinge line
Eliminate flutter by moving the CoG of a control further from the hinge line
Eliminate flutter by moving the CoG of a control further from the hinge line
Increase flutter by moving the CoG of a control closer to the hinge line
Select all the types of mass balance
External
Internal
Horn Balance
Mixed
Flutter is caused by?
CoG to far rearwards
CoG to far forwards
CoP to far rearwards
CoP to far forwards
Select all types of flutter:
Flexural
Torsional
Lateral
Normal
What is the difference between a balance tab and an anti-balance tab?
Select all that apply
Balance tabs move in the same direction and anti-balance tabs move in the opposite direction of the main control surface
Anti-balance tabs reduce control pressures where as balance tabs increase control pressures
Balance tabs move in the opposite direction and anti-balance tabs move in the same direction of the main control surface
Anti-balance tabs increase control pressures where as balance tabs reduce control pressures
What is the purpose of aerodynamic balancing?
To make the control surface easier to move
To make the control surface harder to move
Move the CoP further away from the pilot
To make sure the control surface doesn't go full deflection
Select all the methods of aerodynamic balancing:
Unshielded horn balance
Shielded horn balance
Inset hinges
Internal mass balance
