Compared to Earth, Titan has about one-seventh the gravity but four times the atmospheric density.
These conditions make it easier to fly there.

Overview
The design called for a airplane powered by an advanced Stirling radioisotope generator
The advanced Stirling radioisotope generator (ASRG) is a radioisotope power system first developed at NASA's Glenn Research Center. It uses a Stirling power conversion technology to convert radioactive-decay heat into electricity for use on spacec ...
that would have allowed it to fly uninterrupted for about one year. However, the National Research Council's "Decadal Survey" did not prioritize the moon Titan for exploration, and the development of the advanced Stirling radioisotope generator was suspended indefinitely.
