speed?
Likely because with the nose gear open the air pressure
is the same on top and bottom (maybe even higher on the bottom due to higher
angle of attack). On a top-down air-flow system, to force cool air flow
through the cylinder fins and the oil cooler, the air pressure must be higher
on the top, and lower on the bottom. Therefore, the nose gear door must
be closed to achieve optimum (or perhaps any) air flow where it needs to be
most.
