Crosswind Landings / "Impossible Landing" TE / Crosswind landing advice

Some people use the rudder, some don’t. Those that fly WWII sims too will use it, those having trained on FBW aircraft mostly don’t. The rudder is nice for some corrections. But a plane is made for creating lift at the upside direction. If you “draq” through maneuvers with sideslipping, it isn’t effective. Most of the time, you just create additional drag and the plane of motion is changed more effective with using the stick instead of the rudder.
When you correct a strafing solution, you can either apply a little rudder or just put one wing down and let the pipper drift on the target. Both will give similar results.
Some jet engines even don’t like any sideslipping (like those on the tomcat).I use it sometimes when correcting a gun solution on slow speeds, but not high AOA’s to prevent a departure. For the rest, I have mixed to negative results on using the rudder. Most of the time I find myself correcting errors on the stick with the rudder. You can do that, but I try to correct it with the stick instead of the rudder more and more.
Besides from strafing, on the ground or for some fine correction, I don’t think there is a major use for those. I heard many people telling that the use them, but nobody told me yet any real life F-16 maneuver in which a major amount of rudder input would be used. So I’m pretty much sure they use it for fine correction and the rest is up to the FLCS.
Although I remember that using the rudder to correct a CCRP solution is forbidden as well due to a false FCR solution in that case. Would have to look it up in the multicommand handbook, but it’s late.
However, I would miss them if they wouldn’t be there. Especially in a gun solution where the lift vector matches the bandit’s plane of motion, but is shifted slightly to one side, they are really handy. -

Not true. The turkey can better utilize the rudder with wings spread (lower speeds) and slipping than the F-16. The engines were not the issues with that. Compressor stalls due to engines out of thrust alignment or any disruption of airflow through the intakes were the major cause of compressor stalls. Low speed slipping was not the case for stalls AFAIK.

Rudder is useful both on ground and in flight.

I was told that a low speed sideslip could cause compressor stalls on these engines. Well, if that isn’t the case, I’m always interested in improving my knowledge. Thanks for the information.

Kara Hultgreen’s notorious crash was due to a compressor stall after using the rudder to correct an overshoot in the groove. So, indded it could.

Well,
Not going into it too much, but using rudder at low speeds did not cause a lot of stalls. It is true the Kara’s jet had a compressor stall due too excessive rudder. The Turkey was more prone to low speed high alpha banking (like in my sig pic). As well as throttle misalignment. Any disruption of airflow with the Turkey was bad news. The cool jet combat scenes in Top Gun were not common flight procedures. Even when doing scissors, you had to be careful not to stall the engine.
