Ex 6. Straight & Level flight

Aim: To attain and maintain flight in a straight line, and at a constant altitude.

Airmanship:

  • Lookout
  • Regular checks – Fuel state/consumption rate/engine instruments/etc

Straight flight:

  • Visual reference point
  • Regaining and maintaining visual reference point
  • Use of yaw control to maintain balanced flight

Level flight, (Normal cruise power):

  • Power required dependent on load carried
  • Attitude appreciation and control
  • Use of in-flight trim control (if applicable)
  • Hands-off trim
  • Inherent stability
  • Use of altimeter to check level

Level flight, (Varying power settings and IAS):

  • Power provides height
  • Angle of attack provides speed
  • Power and angle of attack combine to give performance

Attitude control:

  • Use of pitch control to maintain constant attitude to achieve constant I.A.S.

Difference between 3-axis aircraft and weightshift aircraft

Pitch inputs change attitude on both weight shift & 3-axis aircraft, but with a weight shift aircraft the nose attitude in relation to the horizon remains nearly constant with different airspeeds, in a 3-axis aircraft the nose attitude in relation to the horizon changes with different airspeeds
