Hey im huge fan and i know the basic of this game landing taking off etc...
one question to u all
how do i land with the back wheels with out the air plain doesnt go up again.. i know it has to be pitch or something like that
If you bounce when you land your coming in at a too steep an angle and or too fast.
Coming in to fast may also be the problem causing you to balloon or float over the runway. Open up your A/C knee board and look at the refrence section to find your approach speed which is called VREF.
check the included tutorial.
there is a video on the topic.
