I was not being a SA Griffo. Granted the buttons are not ideally located but they are quite obviously in different places on the handgrip - one on the top and the other on the side. Even at night you can clearly see the FD release button on the top. I tell the PNF that I intend to cancel the FD, look down, press the button and hey presto (or e presto! in Italian) - job done with no brown trousers.
5 minutes in the hangar every so often refamilarising the location on these important buttons is not a bad idea if there is any doubt. Or AW could spend millions redesigning it of course.
Safe flying to you too.
