Factors Affecting

S&L (6a)

Controlled by attitude.
70Kts CB 25" - 70Kts in balance.
Air Moving up & down will make us move up and down (Wx effects).
Select Hold Adjust

Climb (6b)

APT 55Kts Max Manifold > 27"
10% rule
Hold onto power until level.

Descent (6c)

PAT 55Kts 18"ish
10% Rule
Effect of bank angle > lower rates of climb, higher rates of descent.
Use of Model Carb' icing, risks and reduction in power when in use.

Turns (6d)

Offset seating effect.
Balance maintained by use of pedals.
Excessive angles result in lower rates of climb and higher rates of descent.

Common Errors

Not holding attitude long enough to allow speed to stabilise, results in overcontrolling.
Poor RRPM control, lack of anticipation of airspeed or lever position change.
Failure to correct yaw during power changes.
Controlling height with cyclic, and speed with power.
On level out, reducing power before speed increases.

Ex. 6 Level Flight, Climbing Descending And Turning

Aim:To learn to how to fly straight and level at a given airspeed, to climb and descend and to turn onto selected headings.
