Yaw/roll - affect on heading
Hi all,
I've recently started my PPL, and am slightly confused as to the use of yaw - I understand the basics, but am struggling to understand how way and roll interact.
I get the secondary effects of ailerons and rudder, but I'm not entirely sure how side slip can work - if inducing yaw, and maintaining straight and level flight, how does the aircraft not change heading? Similarly, when inducing roll, and correcting with the rudder, why does the plane bank?
Surely (well, obviously not!) the aircraft would remain in direction of flight due to the forward vector produced by the thrust of the engine, and similarly changing the direction of the thrust with yaw - the plane should change direction!
What am I missing?
Thanks,
Neil
