I'm totally with Ghengis and I teach cockpit management from day 1. The nub of the problem is the lack of accessible storage space in all the two-seat trainers. The motor accessories industry has back-of-seat pockets as an after-fit option. Perhaps something similar behind the right hand seat that could be closed for transportation and with a carry handle? All that is needed 'to hand' is a map and kneeboard/kneepad (appropriate to type). Sadly, most 'experienced' PPLs are quite resistant to change! I don't share anchorhold's taste for the flying suit - it looks a bit naff in the GA environment, but it's interesting to note that all our instructors wear cargopants because of all the extra pockets.
