Microlight Flight Lessons

• Exercise 4 Effects of Controls
• Flexwing Microlight

3
Aim

• To understand how each control effects the
  aircraft in flight

4
The flight path can be resolved into three planes
of movement
5
Control

• Weight shift
• Primary Control is effected by moving the trike
  unit and hence the centre of gravity. relative to
  the wing

6
Stability

• HANDS OFF TRIM POSITION- H.O.T.
• The aircraft is very stable and can flown hands
  off the control bar. The aircraft will
  automatically correct for small disturbances in
  light turbulence in pitch and to lesser degree in
  role.

7
Primary Attitude Reference

• The Primary reference to the attitude is the
  Horizon

8
Airspeed

• Airspeed is shown by the airspeed indicator. ASI
  , and can be assessed from the pressure of
  airflow on the pilots body

9
ROLLING OR BANKING THE AIRCRAFT

• AS THE AIRCRAFT BANKS IT WILL BEGIN TO
  SLIP.YAW.TURN
• Slip
• Yaw
• Turn

Yaw
Slip
Slip
Nose will lower Into the turn
Turn
10
Rolling or banking the Aircraft

• Moving the control bar laterally causes the
  aircraft to ROLL

Slip
Moving the control bar laterally
Yaw
Rolling back to level
Stabilise in new banked angle
11
Moving the control bar forwards or backwards
causes the aircraft to pitch
Bar Back
Nose pitches up
Bar Forwards
Nose pitches down

• Bar Forwards Nose pitches up
• Bar Back _ Nose pitches down

12
Further Effects
Control Movement Primary Effect Further Effects
Bar Forward Pitch nose up Reduction of airspeed
Bar back Pitch nose down Increase in airspeed
Bar right Roll to the left Slip and yaw to the left
Bar left Roll to the right Slip and yaw to the right
13
Effect of air speed

• High airspeed bar back Light and fast roll
  response
• Low airspeed bar forward Heavy and slow roll
  response

14
Effects of power
The initial effect of increases in power Is a
temporary increase in airspeed
Increase power
Increase in airspeed
Decreasing power
Initial effect of reducing power is A temporary
reduction of airspeed
Decrease In airspeed
15
The further effect of a power change
Decrease power the aircraft will nose down And
descend
Nose Up climb
Increase power
Decrease power
Nose Down descend
Increase power the Aircraft will nose up And
climb
The air speed will settle off to the original
trim speed
16
The effects of Trimmer
Effects of trimmer sets Different amounts of
reflex
This controls the H.O.T position and Hence
H.O.T.airspeed to relieve Yiring out of trim bar
pressure At chosen airspeed

AIRMANSHIP

• Lookout

• At the horizon to assess aircraft attitude and
  for other aircraft

Horizon Aircraft attitude
18
Airmanship Cont-Passing Control

• It is important that the student knows when he is
  control of the aircraft either Instructor or
  Student.
• Also the instructor may ask the student to follow
  through on the controls with the instructor to
  get a feel of the bar movement.
• Instructor You have control
• Student I have control
• Instructor I have control
• Student You have control
• You must relinquish control immediately after
  been asked
