  • $\begingroup$ Also not to be confused with "Point roll". $\endgroup$ Commented 15 hours ago
  • $\begingroup$ Sorry, but the exercise is done with coordinated rudder - rudder is applied in the same direction as the aileron input to cancel the adverse yaw. I think we've confused different activities, please reference the youtube video for the exercise that I mean. This answer doesn't explain why there is no heading change for that exercise. $\endgroup$ Commented 10 hours ago

    $\begingroup$ @Chomeh The explanation is the same. Except your plane has high aspect ratio wings thus has adverse yaw. Your plane, without any rudder input, will turn the opposite direction when you roll. This is adverse yaw. The way adverse yaw work is that the drag of the wings are more than the horizontal component of lift thus the turn is in the opposite direction of lift. When you roll on a point you are correcting adverse yaw JUST ENOUGH to not turn at all. $\endgroup$ Commented 10 hours ago
  • $\begingroup$ ... in a regular coordinated turn you are correcting adverse yaw more than enough to turn in the direction of lift (the opposite direction of drag) $\endgroup$ Commented 10 hours ago
  • $\begingroup$ But the textbook says the aircraft is turned by the horizontal component of lift - if the aircraft is banked (without unloading the elevator) shouldn't it turn irrespective of yaw / slip / skid?. I don't understand how a force about the normal axis could counter a force applied along the normal axis - i.e. they are orthogonal. $\endgroup$ Commented 10 hours ago
