It would appear that we have now found the reason that Sydney trip arms are left
down while Victoria's are latched up.  As an aside, a few tangaras have been fitted
with automatically retracting trips.  When the reverser is placed in the isolate
position, the trip arm automatically raises.  (I think it is called Hall's Trip
Gear)
