Many gliders and helicopters have yaw strings. Airplanes don’t, because they usually have a slip/skid indicator which tells you the same thing.
But once you’ve been flying a while, you don’t really need it, you can feel it.
- kqr 5y agoAccording to Denker, the inclinometer ball doesn't actually measure yaw against wind, but something different that can sorta maybe in most situations be interpreted as yaw against wind. (Specifically, it measures the combination of gravity and centrifugal forces on a motion-constrained mass, from what I can tell: https://www.av8n.com/how/htm/motion.html#sec-centrifugal-airplane https://www.av8n.com/how/htm/motion.html#sec-centrifugal-air...)

- namibj 5y agoOne such maneuver might be a deliberate sideslip during final approach, in particular the transition to no sideslip right after touchdown (unless all wheels steer, which is rare (the B-52 is a notable example)). I'm not too well versed in the details, though.

Comment from a glider instructor of my acquaintance: Yeah, and that big fan in front of the yawstring doesn't help. Might explain why yawstrings are more common in the twin engine case...
