08 Slow Flight

Aim:     

To slow the gyro and maintain straight and level flight at low airspeed and maintain a constant altitude while turning then return to normal operating airspeeds.

Considerations:

Power + Attitude = Performance.

• Lift = Angle of attack x airspeed
• As airspeed decreases angle of attack must increase to maintain level
• High nose attitude + little extra power required
• Fly the gyroplane at a slow speed, but maintain height
• Less control effectiveness = larger inputs required
• Slipstream effects are less – maintain balance
• Medium level turns – need additional power

Airmanship:

• Lookout
  • 20°/2 second scan
• Listen out
• Situational Awareness
• IMSAFE
• Fly using Horizon
• VFR Minima's
• Gyroplane position in training area
• HASELL checks

H            Height                 adequate safe height above the ground

A             Airframe           configuration – clean or flap

S             Security              No loose articles, doors and harnesses secure

E             Engine                 T’s & P’s normal, fuel sufficient

L             Location             Not over populated areas and clear of known traffic areas, including airfields

L             Lookout              one 180°, or two 90° clearing turns for traffic

Aircraft Management:

• Throttle Use
  • Smooth but positive movements
