# IF Turns ## Instrument Flying

#### Review :

• Standard rate one turn is 3 degrees per second.
• The standart rate one turn it’s in relation with airspeed and angle of bank.
• The lower the airspeed at a given angle of bank:
• The higher rate of turn.
• The smaller the radius of turn.
• The rule of thumb to determine approximate angle of bank required for a standard rate turn is to divide your airspeed by 10 and add one half the result.
• Example:
• 120 kt:10 = 12.
• 12:2=6
• 12+6=18
• At 120 kt the approximate angle of bank required for a standard rate turn is 18°.
• When you return from a turn to straight and level flight you have ton anticipate the roll out.
• The amount of lead for the roll out from the turn is approximately ½ angle of bank.
• Exemple:
• If you held 18° of bank in turn  18:2=9  you should begin your roll out 9° before the desired heading.
• A small amount of pitch adjustment may be required during the turn entry and recovery

#### Scan technique: Turn

• What information do I need ?
• Which instrument give me the needed?
• Attitude indicator
• Alitmeter.
• Is the Information reliable ?
• Confirm the reliability of the heading indicator by referring to the turn coordinator and the magnetic compass.
• Confirm the reliability of the altimeter by referring to the airspeed indicator and the vertical speed indicator.
