What are the two turning tendencies that occur during a steep turn?
One of the turning tendencies that occurs during a steep turn is the tendency to over-bank.  This is generally due to the outer wing (wing-up) moving faster thru the air and creating a bit more lift that has to be counter-acted.  A second turning tendency is due to adverse yaw (requiring a bit more rudder during a right hand steep turn).
