05 Straight & Level

Aim: 

To fly the gyro at a constant height, speed, and direction, and in balance. 

Considerations: 

• Horizon
  • the line where the earth’s surface and the sky appear to meet.
• Fly using aircraft’s nose with the horizon

• 4 forces acting in flight 
  • Lift, Weight, Thrust, Drag 
   

• Equilibrium 
  • Constant direction & speed
  • Lift = Weight 
  • Thrust = Drag
   

• Production of Lift 
  • Angle of Attack vs Airspeed 
   

• Power + Attitude = Performance 

• Trim to remove stick force

Airmanship: 

• Lookout 
  • See and be seen 
  • Sectored scan - 20 degrees/2 seconds 
  • Clock code 
• Handover of controls 
  • "I have control/You have control" 
  • "Follow me through" 
• Area Orientation 
  • Local landmarks and boundaries
• VFR Minima's 
  • Clear of cloud 
  • In sight of surface
  • Vis 5km
   
• IMSAFE 

Aircraft Management: 

• Stick, Throttle & Pedal use
  • Positive and smooth movements 
• Trim
  • Back pressure                         trim aft
  • Forward pressure                   trim forward
• T's & P's 
  • Green & normal 
• Cruise ERPM 

• Fuel Management 

Human Factors: 

• Blind spots 
  • Move the head 
• Stress/Information Overload 
  • Practise helps to overcome
   

Exercise: 

Select 

• Ref point on horizon into wind
• Ref altitude
