Really. The lesson is get organised before the flight. In flight two pairs
of eyes are better than one pair. I've done a fair bit of high performance
two seat cross country now in a Nimbus 3DM and 4DM and it is remarkable how
often one pilot will pick up something the other didn't see.
Apart from this there is the difficulty of organising it so the temporary
database is available for in flight editing in a two seater but not a
single seater. Simply getting the co-ords from a map is going to be
difficult enough in the cockpit even in a two seater.
Any setup where the main database is editable on the instrument will have
database integrity until the first pilot gets in the aircraft. We did this
experiment on the B100 which had an editable on the instrument database.
Everyone wanted PC upload of a checked database instead.
