I don't know if it is just me, but having done two dual navs now 1.8 each I am finding that my landings have gone off. I just seem to be too tired and in a bit of a daze? Both times we got back to base the wind had picked up to a decent cross wind. I find crosswinds very challenging at the best of times, and really had trouble keeping the airspeed up, nose in the right direction and am flaring too high. Has anyone else found tiredness and poor concentration at the end of a nav to be a problem? How do you get around that? I have done about 34 hours flying now, thought I should be better, very humbling.
