As a courtesy to the next pilot: when you leave the flight deck, slide the seat fully forward and also tilt it forward. This makes it easier for the next guy to slide their navbag in beside the seat.
I am aware that plenty of people have 'done their back' with a navbag over the years. This is the first time that I have heard of anyone claiming compo.
Do operators to FLI and KI still require that pilots load 55-65Kg bags of cray fish in and out of the aircraft whilst bent double?
