Objectives
To operate the primary control surfaces and observe the first aerodynamic effect on the aircraft in flight
To operate the primary control surfaces and observe the secondary aerodynamic effects on the aircraft in flight
To operate the ancillary controls and observe the effect on the aircraft in flight
Airspeed
Increased airspeed;increased control feel and response, decreased movement needed
Decreased airspeed;decreased control feel and response, increased movement needed
Power
Increase in power -> nose pitch up and yaw left
Decrease in power -> nose pitch down and yaw right
Trim
To relieve the pressure
If holding back pressure -> trim backwards
If holding forward pressure -> trim forward
Flap
Extending flap -> increase in lift and drag -> pitch down
Retracting flap -> decrease in lift and drag -> pitch up
Slipstream
Increased power -> increased slipstream
Increased flow over elevator -> more effective control
Strikes rudder -> yaw
Coordinate with rudder
