Valley Turns

• Use of full width, anticipating need for 360° turn
• Minimise angle of bank to minimise Vs increase
• Lower airspeed to reduce turn radius
• Use of the poor visibility configuration
• Reduced flap to maintain performance i.e. 10° flap as opposed to 20°
• Need for power to combat drag
• Check turns before valley narrows
• Large valley - position anywhere right of centre
• Confined valley - any need to move over to make turn means one is not correctly positioned (Human Factors 5 - 7.5 seconds reaction time)
• Effect of sudden shadow/sun effects
• Clean screen
• Steep gliding turns and effects of changing horizon, narrowing valley
• Roll out position - never in middle of valley
• Always positioned to anticipate not react
• If on wrong side…easy decision to change sides, if in middle potential for indecision and lack of space
• If airspeed decays with full power, lower nose to convert height to airspeed
• Emphasise "caution flying up a valley you haven't previously flown down" philosophy
