It is one of the problems not resolved from any versions.
If you take a PT, you consider of could not land.
You will receive all the types of message what " you have crashed", " you have ditched", but the only way for receive the message "you have landed safely" is to enter inside a port.
Anybody else type of landing, included that in proximity of the field or the TG, in the 99.99% of the cases won't be good.
